Key Takeaways

• The first two weeks post-double jaw surgery represent the most challenging period, with significant facial swelling, strict liquid diet requirements, difficulty speaking, and moderate pain managed through prescription medications
• Swelling peaks around day 3-4 then gradually decreases over 3-6 weeks, with 60-70% resolution by week 2, 80-90% by week 4, and final subtle swelling persisting up to 6 months
• Temporary jaw numbness affects nearly all patients, typically resolving progressively over 3-12 months as the inferior alveolar nerve regenerates, though 5-10% experience permanent mild sensation changes
• Return to work timelines vary dramatically by occupation, with desk jobs often feasible after 2-3 weeks while physically demanding positions may require 6-8 weeks before safe resumption
• Patient satisfaction rates exceed 90% despite challenging recovery, with most individuals reporting the functional and aesthetic improvements far outweigh the temporary discomfort and lifestyle restrictions

Was Jaw Surgery Beneficial?

Patient satisfaction with double jaw surgery consistently ranks exceptionally high, with 90-95% of individuals reporting they would undergo the procedure again knowing what recovery entails. Understanding both benefits and challenges helps set realistic expectations.

Functional improvements represent the primary benefit for most patients. Corrected bite alignment eliminates difficulties chewing, reduces excessive tooth wear, and restores proper oral function. Many patients experience dramatically improved breathing, particularly those whose jaw misalignment contributed to sleep apnea or chronic nasal obstruction. TMJ pain relief occurs in patients whose temporomandibular joint disorders stemmed from skeletal jaw misalignment.

Aesthetic enhancements provide significant psychological benefits. Facial balance and harmony improve as the jaw surgery corrects protruding or receding jaw positions. Profile improvements prove particularly dramatic, with balanced facial proportions replacing previous asymmetry or disproportionate features. Many patients report increased self-confidence and reduced self-consciousness about their appearance.

Quality of life improvements extend beyond physical changes. Patients frequently describe:

• Easier eating and nutrition without chewing difficulties
• Better sleep quality from improved airway function
• Clearer speech when jaw position previously affected articulation
• Reduced chronic pain from TMJ disorders or muscle strain
• Enhanced social confidence from facial appearance satisfaction

Long-term health benefits include reduced risk of tooth loss from excessive wear or bite trauma, decreased likelihood of developing TMJ disorders later in life, potential reduction in sleep apnea severity, and improved overall dental health from proper alignment.

However, realistic expectations matter tremendously. The recovery process proves challenging, requiring significant lifestyle adjustments, dietary restrictions, and patience through healing stages. Some patients experience permanent mild numbness, minor facial asymmetry, or need for secondary refinement procedures. Despite these considerations, the overwhelming majority find the benefits far exceed temporary recovery challenges.

How Long Were You Unable to Work?

Time off work after double jaw surgery varies considerably based on multiple factors including job type, surgical complexity, individual healing rates, and employer flexibility regarding modified duties.

Desk jobs and remote work typically allow return within 2-3 weeks post-surgery. By this point, major swelling has decreased enough for reasonable appearance, pain is manageable with over-the-counter medication, and energy levels support sitting at a computer. However, factors like video conference requirements may extend time off if facial swelling causes self-consciousness. Many patients successfully work from home starting week 2, avoiding commute fatigue while gradually rebuilding stamina.

Jobs requiring public interaction (retail, customer service, teaching) often necessitate 3-5 weeks absence. Residual facial swelling, difficulty speaking clearly, and potential self-consciousness about appearance influence this timeline. Speech clarity improves significantly by week 3-4 as swelling decreases and patients adapt to their new jaw position.

Physically demanding occupations (construction, nursing, warehouse work) require 4-8 weeks before safe return. Heavy lifting restrictions typically extend 6-8 weeks to prevent increased facial pressure that could compromise healing. Jobs requiring strenuous activity risk increased swelling, bleeding, or surgical site disruption if resumed prematurely.

Healthcare professionals and emergency responders face unique challenges. Long shifts, physical demands, and high-stress environments may necessitate 6-8 weeks off. Additionally, jaw wiring or facial numbness can complicate wearing protective equipment like N95 masks properly.

Self-employed individuals and business owners often attempt earlier returns, sometimes working modified schedules starting week 2-3. However, reduced energy levels during healing may compromise work quality or productivity. Many find gradual return strategies (half-days initially, progressive increase) most sustainable.

Factors affecting individual timelines include:

• Surgical complexity (single vs. double jaw surgery)
• Presence of complications requiring extended recovery
• Individual pain tolerance and healing rate
• Support system availability for assistance during recovery
• Employer accommodation regarding flexible scheduling or remote work

Disability and leave planning: Patients should arrange short-term disability if available, ensuring adequate financial support during recovery. FMLA (Family and Medical Leave Act) protects job positions for qualifying employees. Discuss timeline expectations with surgeons early, obtaining documentation for employers regarding expected absence duration and return-to-work restrictions.

Duration of Drooling and Bleeding Post-Surgery

Minor bleeding and drooling represent normal early recovery experiences that resolve relatively quickly but cause considerable concern for unprepared patients.

Post-operative bleeding typically manifests as pink-tinged saliva rather than frank blood. This minor oozing occurs from intraoral incisions and resolves within 3-7 days for most patients. The first 48-72 hours show the most noticeable bleeding, gradually decreasing daily. Patients should expect to:

• Change gauze pads frequently during the first 24-48 hours
• See pink or light red-tinged saliva when rinsing
• Notice occasional small blood clots in saliva
• Experience increased oozing with activity or lowering the head

Concerning bleeding requiring immediate medical attention includes bright red blood filling the mouth repeatedly, bleeding that doesn’t slow after 20 minutes of gentle pressure, or large blood clots that impair breathing. These situations occur rarely but demand prompt evaluation.

Excessive drooling proves frustrating but temporary. Facial numbness, particularly affecting lips and chin, impairs normal saliva control mechanisms. Additionally, increased saliva production occurs as a physiological response to oral surgery. Swelling further complicates normal swallowing coordination. Most patients experience problematic drooling for 3-7 days, with gradual improvement as:

• Facial swelling decreases allowing better mouth closure
• Sensation begins returning to lips and surrounding areas
• Saliva production normalizes after the initial inflammatory response
• Patients develop compensatory swallowing techniques

Managing drooling and bleeding:

• Keep absorbent cloths or towels readily available, particularly at bedside
• Sleep with head elevated on multiple pillows to reduce pooling
• Use dark-colored pillowcases to hide staining
• Rinse gently with prescribed mouthwash or salt water to remove accumulating blood
• Avoid touching surgical sites with tongue or fingers despite the urge
• Apply light pressure with gauze if bleeding increases, avoiding aggressive wiping

Saliva management improves significantly by day 4-5 for most patients. By week 2, drooling becomes minimal even with residual facial numbness. Complete control returns as sensation normalizes over subsequent weeks and months.

How Long Did the Swelling Last?

Facial swelling after double jaw surgery follows a predictable pattern, though individual variation exists. Understanding the swelling timeline helps patients prepare mentally and practically for recovery.

Immediate post-operative period (Hours 0-24): Swelling begins immediately after surgery, gradually increasing throughout the first day. By evening of surgery day, patients notice significant facial fullness, particularly around the cheeks, jaw angles, and neck.

Peak swelling (Days 2-4): Maximum facial swelling occurs around day 3-4 post-surgery. Patients often describe feeling like a “chipmunk” with dramatic facial enlargement. Mirror avoidance during this period is common as appearance changes dramatically. The face feels tight, heavy, and uncomfortable. Swelling during peak days can:

• Make eyes appear smaller or even completely close in severe cases
• Extend down the neck creating a double or triple chin appearance
• Cause difficulty opening the mouth even slightly
• Create significant facial asymmetry (one side often swells more than the other)
• Impair breathing through the nose due to internal nasal swelling

Rapid improvement phase (Weeks 1-2): Approximately 40-50% of swelling resolves during the first two weeks. Patients notice dramatic day-to-day improvement, with the most significant changes between days 5-10. By end of week 2, most patients look substantially more normal, though still noticeably swollen to close observers.

Continued gradual improvement (Weeks 2-6): Another 30-40% of swelling decreases during this period. By week 4, approximately 80-85% of swelling has resolved. Patients typically feel comfortable appearing in public without drawing excessive attention. Close friends and family still notice residual fullness, but casual acquaintances may not detect obvious swelling.

Final subtle swelling (Months 2-6): The last 10-15% of swelling resolves very gradually over 3-6 months. This residual swelling typically manifests as:

• Slight fullness under the chin or neck
• Morning puffiness that decreases throughout the day
• Subtle asymmetry between sides
• Mild tightness with certain facial expressions

Factors affecting swelling duration:

• Surgical complexity: Double jaw surgery produces more swelling than single jaw procedures
• Individual healing response: Some patients naturally swell more than others
• Post-operative care adherence: Proper ice application, head elevation, and activity restrictions minimize swelling
• Age: Younger patients often experience faster swelling resolution
• Pre-existing conditions: Lymphatic or circulation issues may prolong swelling

Managing swelling effectively:

• Apply ice packs for 20 minutes on, 20 minutes off during first 48-72 hours
• Sleep with head elevated 30-45 degrees on multiple pillows for 2-3 weeks
• Avoid bending over, heavy lifting, or straining during initial weeks
• Stay well-hydrated to support lymphatic drainage
• Follow prescribed medication regimens including any steroids given to reduce inflammation
• Consider arnica supplements (consult surgeon first) which some believe reduce bruising and swelling
• Perform gentle facial massage (only after surgeon approval, typically week 3-4+) to promote fluid drainage

Duration of Discomfort After Jaw Surgery

Pain and discomfort represent unavoidable aspects of double jaw surgery recovery, though modern pain management techniques have dramatically improved patient comfort compared to historical experiences.

Immediate post-operative pain (Days 1-3): Patients typically experience moderate to severe discomfort during the first 72 hours. Pain stems from surgical incisions, bone manipulation, soft tissue swelling, and jaw repositioning. Intravenous pain medication in the hospital provides substantial relief. Once home, prescription pain medication (typically opioids like oxycodone or hydrocodone) manages discomfort effectively when taken as prescribed.

Early recovery discomfort (Days 4-10): Pain intensity typically decreases progressively during this period. Many patients transition from prescription opioids to over-the-counter medications like ibuprofen or acetaminophen by day 7-10. Discomfort characteristics evolve from sharp pain to dull aching, tightness, and jaw soreness.

Mid-recovery phase (Weeks 2-6): Pain largely resolves by week 2-3, replaced by tightness, stiffness, and muscle soreness. Attempting to open the mouth wider causes pulling sensations. Eating and speaking create fatigue in jaw muscles unaccustomed to the new skeletal position. Most patients manage this discomfort with occasional over-the-counter pain relievers.

Late recovery (Weeks 6-12): Minimal pain persists, though patients notice occasional jaw soreness after eating challenging foods or talking extensively. Muscle adaptation to the new jaw position continues, sometimes causing temporary discomfort as muscles strengthen and coordination improves.

Types of discomfort experienced:

• Incisional pain: From surgical cuts inside the mouth
• Pressure and tightness: From facial swelling
• Jaw soreness: From repositioned bones and stretched muscles
• Headaches: Common from stress, muscle tension, and altered bite
• Ear pain: Referred pain from jaw surgery often manifests near ears
• Throat discomfort: From intubation during surgery, resolves within days
• Neck stiffness: From positioning during surgery and subsequent limited movement

Pain management strategies:

• Take pain medication before pain becomes severe rather than waiting
• Use ice therapy during first 48-72 hours to reduce inflammation-related pain
• Maintain head elevation to minimize pressure and throbbing
• Follow the prescribed medication schedule rather than trying to “tough it out”
• Transition gradually to weaker pain medication to avoid rebound discomfort
• Stay well-hydrated as dehydration exacerbates pain perception
• Rest adequately as fatigue lowers pain tolerance

Individual pain tolerance varies dramatically. Some patients describe the experience as “less painful than expected” while others find it “the most challenging thing ever done.” Realistic expectations based on understanding that significant discomfort is normal but manageable help patients cope psychologically with recovery demands.

What Products Were Essential During Recovery?

Recovery supplies significantly impact comfort and recovery success. Being well-prepared before surgery eliminates stress during the challenging first weeks.

Nutritional supplies:

• High-quality protein powder (whey, plant-based, or collagen) for nutritional shakes
• Blender or food processor capable of completely liquefying foods
• Meal replacement shakes like Ensure Plus, Boost, or Orgain
• Liquid vitamin supplements since pill swallowing may be difficult
• Reusable smoothie cups with wide openings for easy consumption
• Syringes (without needles) for administering liquids if jaw is wired
• Insulated containers to maintain food temperature longer

Oral hygiene products:

• Prescribed antiseptic mouthwash for infection prevention
• Salt for homemade saline rinses
• Water flosser or oral irrigator for cleaning around surgical sites and hardware
• Extra-soft toothbrush or child’s toothbrush for gentle cleaning
• Non-alcoholic mouthwash as alcohol-based versions may irritate surgical sites

Comfort and healing supplies:

• Ice packs (at least 4-6) for rotation, gel packs conform better to facial contours
• Soft cloth covers for ice packs to prevent skin irritation
• Multiple pillows for head elevation during sleep
• Wedge pillow specifically designed for elevated sleeping
• Humidifier for bedroom to prevent dry mouth and aid breathing
• Lip balm as mouth breathing and numbness cause severe chapping
• Absorbent cloths or small towels for managing drooling
• Dark pillowcases to hide minor bleeding stains

Entertainment and distraction:

• Streaming service subscriptions for shows and movies during recovery
• Books, magazines, or audiobooks for distraction
• Comfortable clothing with front buttons (avoid pulling over head)
• Notebook for tracking medications, pain levels, and questions for surgeon

Practical items:

• Grabber tool for reaching items without bending over
• Flexible straws if surgeon approves straw use
• Hand mirror for examining mouth and surgical sites
• Medical alert bracelet noting jaw surgery for emergency situations
• Copy of surgeon’s contact information easily accessible

Items patients wish they’d had:

• Baby wipes for easy cleaning when showering is exhausting
• Dry shampoo for days when washing hair feels overwhelming
• Eye drops for dryness from medication side effects
• Arnica supplements (with surgeon approval) potentially reducing bruising
• Stool softener as pain medication commonly causes constipation
• Facial massage oil or cream for later recovery phase (after clearance)

Frequency of Doctor Visits After Surgery

Post-operative follow-up schedule ensures healing progresses appropriately and allows early intervention if complications arise. Understanding the typical appointment timeline helps patients plan accordingly.

Immediate post-operative period:

Day 1-2: Many patients remain hospitalized 1-3 days post-surgery. Daily rounds by the surgical team monitor vital signs, pain control, initial healing, and oral intake tolerance. Discharge planning occurs once patients demonstrate stable vital signs, adequate pain control on oral medication, ability to tolerate liquid nutrition, and understanding of home care instructions.

Week 1 appointment: The first post-discharge visit typically occurs 5-7 days post-surgery. This critical appointment assesses:

• Incision healing and infection signs
• Swelling progression (should be decreasing after peak)
• Pain management adequacy
• Nutritional intake and hydration status
• Any early complications requiring intervention
• Removal of any non-absorbable sutures if used

Week 2-3 appointment: This visit evaluates continued healing progress and addresses any concerns that have developed. Surgeons may obtain early X-rays to verify bone alignment remains appropriate. Patients receive guidance on beginning gentle jaw stretching exercises if healing permits.

Week 4-6 appointment: A crucial visit where surgeons assess bone healing progress through clinical examination and usually radiographic imaging. Key decisions made include:

• Dietary advancement approval from liquids to soft foods
• Elastic or wire removal if jaw was immobilized
• Clearance for increased physical activity if healing appropriately
• Discussion of any sensation changes and expected recovery
• Assessment of bite alignment and occlusion

Week 8-12 appointment: This visit confirms adequate bone union and addresses any functional concerns. Patients typically receive clearance for resuming normal diet progressively and unrestricted daily activities with continued caution regarding contact sports.

Month 3-6 follow-ups: Less frequent appointments (every 4-8 weeks) monitor long-term healing, assess final aesthetic outcomes, evaluate sensation recovery, and determine if any refinement procedures might benefit results.

One-year follow-up: A final comprehensive evaluation includes complete X-ray series, assessment of final bone remodeling, evaluation of TMJ function, documentation of final aesthetic result, and discussion of any long-term concerns or additional treatments.

Additional appointments occur if:

• Complications develop (infection, non-union, hardware issues)
• Excessive pain or swelling beyond normal expectations
• Significant bleeding that doesn’t resolve
• Breathing difficulties or other concerning symptoms
• Bite feels off or teeth don’t meet properly
• Questions or concerns arise between scheduled visits

Most surgeons encourage open communication via phone or patient portal between appointments, addressing minor concerns without requiring office visits while ensuring serious issues receive prompt in-person evaluation.

Cost of Jaw Surgery

Double jaw surgery cost varies dramatically based on geographic location, surgeon experience, hospital facility, insurance coverage, and surgical complexity. Understanding financial considerations helps patients plan appropriately.

United States costs:

Without insurance: $40,000-$60,000 represents typical total costs including:

• Surgeon fees: $15,000-$25,000
• Hospital facility charges: $15,000-$25,000
• Anesthesiologist fees: $3,000-$5,000
• Pre-operative imaging and planning: $2,000-$3,000
• Post-operative care and follow-up: $1,000-$2,000

With insurance: Coverage depends on establishing medical necessity. Insurers typically cover functional jaw surgery addressing documented problems like severe malocclusion causing chewing difficulty, obstructive sleep apnea from jaw structure, chronic TMJ disorders unresponsive to conservative treatment, or congenital deformities. Patient out-of-pocket costs with insurance often range $5,000-$15,000 including deductibles, co-pays, and any portions deemed not medically necessary.

Purely aesthetic jaw surgery (no functional problems documented) faces full out-of-pocket responsibility as cosmetic procedures lack insurance coverage.

International costs (medical tourism):

• South Korea: $15,000-$25,000 comprehensive packages
• Turkey: $8,000-$15,000 including accommodation and transfers
• Thailand: $12,000-$20,000 with medical tourism support
• Mexico: $10,000-$18,000, convenient for North American patients
• India: $6,000-$12,000, most affordable option

Additional costs to consider:

• Pre-surgical orthodontics: $3,000-$8,000 for 12-18 months of braces before surgery
• Post-surgical orthodontics: $2,000-$5,000 for bite refinement after healing
• Time off work: Lost wages during 2-6 week recovery
• Travel expenses: For patients seeing surgeons far from home
• Recovery supplies: $300-$600 for nutritional supplements, medical supplies
• Childcare or assistance: If needing help during early recovery

Financial planning strategies:

• Verify insurance coverage thoroughly before proceeding, obtaining pre-authorization
• Health Savings Accounts (HSA) or Flexible Spending Accounts (FSA) can pay qualified medical expenses with pre-tax dollars
• Payment plans offered by many surgical practices spread costs over time
• Medical credit cards like CareCredit provide financing options
• Negotiate cash discounts as some providers reduce fees for upfront payment
• Medical tourism consideration for significant savings with thorough vetting of international facilities

When Could You Start Chewing Food Again?

Resuming chewing represents one of the most anticipated recovery milestones, though the timeline requires patience to protect healing bone and surgical sites.

Weeks 0-2: No chewing whatsoever. The strictly liquid diet during this period provides all nutrition through smoothies, protein shakes, blended soups, and meal replacement beverages. Attempting any chewing risks disrupting bone alignment or loosening surgical hardware.

Weeks 2-4: Continued no-chew diet. Most patients remain on liquids or very soft purees that slide down without jaw movement. Some surgeons permit pureed foods like mashed potatoes, yogurt, or scrambled eggs that require only tongue manipulation for swallowing, but no actual chewing.

Weeks 4-6: First minimal “chewing”. With surgeon approval based on healing assessment, patients may introduce extremely soft foods requiring minimal pressure. This includes:

• Very overcooked pasta
• Soft scrambled eggs
• Well-mashed beans
• Soft fish that flakes apart
• Ripe banana in small pieces

Even these foods should be approached cautiously, using back molars only and applying gentle pressure. Front teeth remain off-limits for biting.

Weeks 6-8: Soft foods with gentle chewing. Progressive dietary advancement includes:

• Ground meat cooked very moist
• Soft breads (no crusts)
• Cooked vegetables cut very small
• Soft fruits like melon or ripe pears
• Tender chicken or turkey

Chewing technique during this phase emphasizes slow, deliberate movements using back teeth with minimal force.

Weeks 8-12: Gradual return to normal textures. Most patients receive clearance for most regular foods during this timeframe, though progression should remain gradual:

• Week 8: Introduce slightly firmer foods like regular pasta, softer meats
• Week 10: Add foods requiring moderate chewing like sandwiches, cooked vegetables
• Week 12: Attempt more challenging textures like salads, tender steak, fresh vegetables

Foods to avoid until 3-4 months post-surgery:

• Very hard foods: Nuts, hard candies, ice, raw carrots
• Extremely chewy items: Tough meats, bagels, chewy candies
• Sticky foods: Caramel, taffy, very sticky rice
• Foods requiring wide mouth opening: Large burgers, whole apples, corn on the cob

Individual variation in timelines depends on:

• Surgical complexity: Double jaw surgery typically requires longer restrictions than single jaw
• Healing rate: Some patients heal faster, receiving earlier dietary advancement clearance
• Presence of jaw wiring: Patients with prolonged maxillomandibular fixation face longer liquid diet periods
• Complications: Healing delays extend dietary restrictions

Never advance your diet without explicit surgeon approval. Premature chewing risks serious complications including bone non-union, hardware loosening, bite misalignment, or fracture site disruption requiring revision surgery.

Did You Regain Sensation in Your Lower Jaw?

Temporary numbness following jaw surgery represents one of the most common and concerning side effects, though understanding expected recovery timelines alleviates anxiety.

Why numbness occurs: The inferior alveolar nerve runs through the lower jaw bone, providing sensation to the lower lip, chin, teeth, and gums. Jaw surgery requires cutting and repositioning bone surrounding this nerve. While surgeons take extreme care to avoid direct nerve damage, the manipulation, bone movement, and post-operative swelling inevitably affect nerve function temporarily.

Immediate post-operative period: Complete numbness of the lower lip and chin is universal immediately after surgery. Patients cannot feel the surgical area, their lip position, or even determine if they’re drooling. This dense numbness persists during the first 1-2 weeks.

Weeks 2-4: First sensation return. Many patients notice initial tingling or “pins and needles” sensations, indicating nerve recovery beginning. This stage feels uncomfortable, with unusual sensations described as:

• Electric buzzing or vibrating feelings
• Itching that can’t be scratched effectively
• Hypersensitivity to touch or temperature
• Awkward awareness that sensation isn’t quite normal

Months 1-3: Progressive improvement. Gradual sensation return accelerates during this period. Patients typically recover 40-60% of normal sensation by month 3, with continued steady improvement. However, asymmetric recovery is common, with one side improving faster than the other.

Months 3-6: Continued recovery. Most patients achieve 70-80% sensation recovery by six months post-surgery. Remaining numbness typically affects smaller areas, often concentrated in the chin or lower lip center. Functional sensation returns sufficiently that patients can eat, drink, and speak comfortably without awareness of deficits.

Months 6-12: Final improvements. Additional subtle improvements continue throughout the first year, with many patients reaching 85-95% normal sensation. However, some individuals notice permanent subtle differences in sensation quality—areas may feel slightly “different” compared to before surgery without constituting true numbness.

Long-term outcomes:

• Complete or near-complete sensation recovery: 70-80% of patients
• Mild permanent numbness (noticeable but not functionally limiting): 15-20% of patients
• Moderate permanent numbness (affects function or quality of life): 5-10% of patients
• Severe permanent numbness: <5% of patients

Factors affecting sensation recovery:

• Age: Younger patients (under 25) typically recover sensation more completely and quickly
• Nerve proximity to fracture site: Closer proximity increases injury risk
• Surgical technique and skill: Experienced surgeons minimize nerve trauma
• Individual nerve regeneration capacity: Varies person to person
• Presence of pre-existing nerve compromise: Degenerative conditions may limit recovery

Managing persistent numbness:

• Patience: Nerve regeneration occurs slowly over many months
• Gentle massage (after surgeon clearance) may promote blood flow and healing
• Vitamin B12 supplementation: Some believe this supports nerve healing, though evidence is limited
• Protective awareness: Numbness means reduced pain sensation, requiring caution with hot foods, sharp objects, or biting the lip/cheek accidentally

When to be concerned: While slow sensation recovery is normal, worsening numbness or development of severe neuropathic pain (burning, shooting pains) warrants evaluation. These symptoms might indicate nerve compression from swelling, hardware pressure, or other issues requiring intervention.

Most patients ultimately adapt successfully even if some mild permanent numbness persists, finding functional limitations minimal despite initial concerns. The trade-off between temporary or mild permanent numbness and the functional and aesthetic improvements from jaw surgery remains worthwhile for the vast majority of individuals.
