Sleep Apnea Surgery
For patients who cannot tolerate CPAP therapy, surgical intervention may provide a permanent solution to obstructive sleep apnea. Dr. Krajekian uses Virtual Reality planning to precisely address airway obstructions.
Understanding Obstructive Sleep Apnea (OSA)
OSA occurs when the airway collapses during sleep, causing:
- •Loud snoring
- •Gasping or choking during sleep
- •Excessive daytime sleepiness
- •Morning headaches
- •Difficulty concentrating
- •Increased cardiovascular risk
Surgical Treatment Options
Maxillomandibular Advancement (MMA)
MMA is the most effective surgical treatment for moderate to severe OSA:
- •Advances both upper and lower jaws forward
- •Enlarges the entire airway
- •90%+ success rate in properly selected patients
- •Permanent solution
- •Often eliminates need for CPAP
VR Planning for MMA:
- •3D airway analysis
- •Virtual advancement simulation
- •Prediction of airway improvement
- •Custom surgical guides for precision
Genioglossus Advancement (GA)
Advances the tongue muscle attachment:
- •Pulls tongue forward
- •Prevents tongue from falling back
- •Often combined with other procedures
- •Less invasive than MMA
Hyoid Suspension
Repositions the hyoid bone:
- •Stabilizes the airway
- •Prevents collapse at the tongue base
- •Often combined with GA
Nasal Surgery
Improves nasal airflow:
- •Septoplasty
- •Turbinate reduction
- •Addresses nasal obstruction component
Palatal Surgery
Addresses soft palate collapse:
- •Uvulopalatopharyngoplasty (UPPP)
- •Expansion sphincter pharyngoplasty
- •Removes or repositions excess tissue

- •Swelling continues to decrease
- •Gradual increase in jaw opening
- •Follow-up sleep study at 3–6 months
- •Most patients off CPAP immediately
Long-Term
- •Sleep study confirms improvement
- •Maintain healthy weight
- •Avoid alcohol before sleep
- •Regular follow-up appointments
- •Most patients report dramatic improvement in quality of life
Key Benefits
- •CPAP-free permanent solution
- •VR-planned airway analysis
- •3D-printed surgical guides
- •90%+ success rate for MMA
- •Improved sleep and energy
- •Reduced cardiovascular risk
Recovery Time
2-4 weeks initial; 6-12 weeks jaw mobility

OSA Treatment Overview
Treatment ranges from conservative lifestyle changes to advanced surgical intervention, depending on severity
Non-Surgical Options
Lifestyle Modification
Weight loss (even 10 lbs can help), changing sleep position, avoiding alcohol and sedatives before bed, and maintaining a regular sleep schedule.
Oral Appliances
Custom-molded devices worn at night to position the lower jaw forward, elevate the soft palate, and prevent the tongue from blocking the airway. Effective for mild to moderate OSA.
C-PAP / Bi-PAP Devices
Continuous or bi-level positive airway pressure delivered through a fitted mask prevents airway collapse during sleep. First-line treatment for moderate to severe OSA.
Surgical Options
Maxillomandibular Advancement (MMA)
Surgically advances both upper and lower jaws forward, moving the tongue and soft palate to permanently open the upper airway. The most effective surgical treatment for moderate to severe OSA. Dr. Krajekian uses piezoelectric instruments for precise bone cuts that protect nerves and blood vessels, combined with biologics (PRF, BMAC) at the osteotomy sites to accelerate healing.
Uvulopalatopharyngoplasty (UPPP)
Shortens and stiffens the soft palate by partially removing the uvula and reducing the edge of the soft palate, addressing airway collapse at the palatal level.
Genioglossus Advancement & Hyoid Suspension
GGA tightens the front tongue tendon to prevent the tongue from falling back; hyoid suspension stabilizes the hyoid bone to prevent collapse at the tongue base. Often performed together.
Dr. Krajekian's Advanced Approach
Sleep apnea surgery has advanced significantly. VR planning, piezoelectric instruments, and regenerative biologics deliver safer procedures and faster recovery.
VR Airway Planning
Dr. Krajekian uses Virtual Reality to visualize the entire upper airway in 3D, plan precise jaw advancements, and rehearse the surgery before the first incision, ensuring optimal airway opening.
Piezoelectric Surgery
Ultrasonic piezoelectric instruments cut bone with precision while preserving nerves and blood vessels. This means less swelling, reduced nerve injury risk, and faster recovery after MMA surgery.
Biologics for Healing
Platelet-Rich Fibrin (PRF) and Bone Marrow Aspirate Concentrate (BMAC) are applied at osteotomy sites to accelerate bone healing, reduce inflammation, and promote faster recovery, using the patient's own biology.
3D-Printed Custom Guides
Patient-specific surgical guides and splints are 3D-printed from the VR plan, ensuring the jaw advancement matches the planned position exactly, with sub-millimeter accuracy for optimal airway results.

AHI Severity Classification
Understanding your Apnea-Hypopnea Index (AHI) score from your polysomnography (sleep study) results
Understanding Your Sleep Study Results
The Apnea-Hypopnea Index (AHI) is the gold standard for measuring sleep apnea severity. It counts the number of times per hour your breathing partially (hypopnea) or completely (apnea) stops during sleep, as recorded by a polysomnography (sleep study). The American Academy of Sleep Medicine (AASM) classifies OSA severity as follows:
Surgical Success Rates
Published peer-reviewed data on surgical outcomes for obstructive sleep apnea treatment
MMA: The Gold Standard for Surgical OSA Treatment
A landmark meta-analysis of 627 patients demonstrated that Maxillomandibular Advancement achieves an overall surgical success rate of 86%, with a mean AHI reduction from 63.9 to 9.5 events/hr, an 85% reduction in sleep-disordered breathing events. The cure rate (AHI < 5) was 43%.

MMA Success Rate by OSA Severity
Success defined as AHI < 20 and ≥50% reduction (Sher criteria). Data from Holty & Guilleminault, Sleep 2010.
Surgical Outcomes by Procedure
Maxillomandibular Advancement (MMA)
Most effective surgical treatment for moderate-to-severe OSA
Holty & Guilleminault, Sleep 2010 • 627 patients
Phase I (UPPP + Genioglossus Advancement)
First-line surgical approach; targets palatal and tongue-base obstruction
Riley et al., Otolaryngology HNS 1993 • 239 patients
Phase II (MMA after Phase I)
Reserved for patients who do not respond to Phase I surgery
Riley et al., Otolaryngology HNS 1993 • Phase I non-responders
UPPP Alone
Most effective when obstruction is primarily at the palatal level; less effective for severe OSA
Sher et al., Sleep 1996 • Meta-analysis
Surgical outcomes depend on patient selection, site of airway obstruction, BMI, and other individual factors. Dr. Krajekian performs a comprehensive evaluation including 3D airway analysis and VR surgical planning to determine the optimal treatment approach for each patient. These statistics represent published peer-reviewed data and individual results may vary.
