Maxillomandibular Advancement Surgery in Treatment of Moderate to Severe Obstructive Sleep Apnea

Maxillomandibular advancement surgery (MMA) is an alternative treatment for moderate to severe OSA in patients unable or unwilling to adhere to the gold standard CPAP therapy. MMA reduces pharyngeal collapsibility, helping to reduce AHI and sleep fragmentation. It is well established that MMA is the most effective surgical treatment in resolving OSA with reported success rates of 85-91%. Furthermore there is evidence that MMA surgery provides significant further improvements beyond successful CPAP and Mandibular Advancement Therapy (MAD).

However, there is a need for patient specific and individualized approach to treatment of OSA, as treatment success varies amongst patients.  Successful MAD treatment can be a positive predictor of success for MMA surgery.

Dr. Meisami will discuss the use of MAD and DISE (Drug Induced Sleep Endoscopy) as diagnostic tools prior to MMA surgery to guide in predicting treatment success and potentially eliminating patients who would ultimately not benefit from MMA surgery.


  1. Review the Evidence in MMA surgery success in treatment of OSA
  2. Understand the vital role OMFS and Orthodontists play in surgical management of OSA
  3. Distinguish the differences between MMA surgery and Orthognathic surgery: indications, patient selection, treatment objectives and sequence
  4. Understand the use of diagnostic tools such as MAD and DISE in predicting success in MMA surgery

Oral Appliances, MARPE and Non-Surgical Management of the OSA/TMD Patient

Dr. Stephen Ho

DDS., MSc., FRCD(C), FADSA | CVOS Oral Surgery

This lecture will start with a review of the current generation of mandibular repositioning devices for OSA management. Upon this foundation we will then touch upon the evidence for evolving therapies such a Mini Screw Rapid Palatal Expansion in adults (MARPE). Finally, the overlap between the OSA and the TMD patient will also be addressed using non-surgical modalities.

Learning Objectives: At the conclusion of the lecture, participants should:

  1. Discuss positive indictors for oral appliance therapy
  2. Understand the different generations of oral appliances and the current innovations
  3. Know what current titration strategies exist for oral appliance therapy
  4. Understand the principles and evidence for MARPE 
  5. Discuss the treatment planning for the OSA/TMD patient

Dr. Ho completed his dental training at the University of Toronto. He then completed a hospital dental residency jointly at the University of Illinois at Chicago and the University of Chicago. Dr. Ho returned to the University of Toronto for his specialty training in Oral and Maxillofacial Surgery and Anesthesia. Dr. Ho has taken post-graduate medical education in Sleep Apnea Diagnosis and Treatment. Dr. Ho has focused expertise in the area of Obstructive Sleep Apnea as well as CT-based 3D treatment planning for dental implants, corrective jaw surgery and airway size determination. Dr. Ho’s 3D treatment planning expertise has allowed him to participate as a lecturer and professional resource to other dental specialists performing their own surgery.

Dr. Ho founded the Airway ENT and Oral Surgery Clinic. This pioneering clinic has an interdisciplinary team of physicians, dentists, physiotherapists and chiropractors united in the treatment of the OSA and TMD patient.
