Objective and Subjective Outcomes Following Maxillomandibular Advancement Surgery for Treatment of Patients With Extremely Severe Obstructive Sleep Apnea (Apnea-Hypopnea Index >100).

Purpose: It is important for patients and treating clinicians to know whether maxillomandibular advancement (MMA) surgery is effective when treating patients with obstructive sleep apnea syndrome (OSAS) and an extremely high apnea-hypopnea index (AHI) score. The purpose of this study was to evaluate objective and subjective treatment outcomes after MMA surgery for the treatment of OSAS in patients with a preoperative AHI score higher than 100.

Patients And Methods: This retrospective study included all patients who underwent MMA surgery for OSAS by members of the Department of Oral and Maxillofacial Surgery, QEII Health Science Centre (Halifax, Nova Scotia, Canada) from November 1996 through February 2014.

Subjective outcomes of maxillomandibular advancement surgery for treatment of obstructive sleep apnea syndrome.

Purpose: To evaluate subjective outcomes and use of continuous positive airway pressure (CPAP) after maxillomandibular advancement surgery for treatment of obstructive sleep apnea syndrome (OSAS).

Patients And Methods: A self-administered questionnaire was completed pre- and postoperatively by 116 patients who underwent maxillomandibular advancement surgery for treatment of OSAS from February 2000 through September 2010. The questionnaire included the Epworth Sleepiness Scale (ESS) for assessment of daytime somnolence and questions regarding snoring, witnessed apneas, CPAP use, and overall satisfaction.
