The aim of this study was to assess changes in the profile of adult male patients treated for obstructive sleep apnea syndrome (OSAS) with maxillomandibular advancement (MMA) surgery and to measure patient perception of changes compared with that of different panels.

Fifteen consecutive apneic patients displaying a wide variety of morphological types, mean age 42years (20–59), a BMI of 26.60kg/m² (22–29), a mean initial Apnea Hypopnea Index (AHI) of 50.9 (19–85), underwent MMA. Assessment was done by facial photography, lateral cephalographs (Tweed analysis modified by Riley and Delaire architectural analysis), polysomnographic records and a validated self-assessment questionnaire. Patients’ pre- and postoperative profiles were taken from photographs using Photoshop 7™ software. Their darkened outlines were shown randomly in positions A or B (pre- and postoperative) to panels composed of orthodontists (n=40), fine arts students (n=50) and lay persons (n=50) who were requested to choose the most attractive profiles.

The MMA success rate for OSAS was 80% (12/15) for an AHI less than 15, with no surgical complications. All patients reported a reduction of their symptoms and 14 out of 15 were satisfied with the esthetic outcome. Mean advancement was 8.4mm (3.0–10.0) for the maxilla and 10.8mm (10.0–13.0) for the mandible. Following MMA, 12 out of 15 exhibited maxillary protrusion and six out of 15 mandibular protrusion. The mean change in the nasolabial angle was −5.7° (−27°; 14°). The postoperative profiles were preferred by 85% of the combined panels (P=<0.001), showing no significant difference from one panel to another. No skeletal characteristic could be correlated with the esthetic preference. Upper lip retrusion, open nasolabial angle and dolichofacial type emerged as positive preoperative predictors of esthetic preference.

The profile changes following MMA were favorably perceived in the majority of cases. However, specific orthodontic preparation could be offered to patients with pronounced preoperative protrusion.
