Abstract
Objective To explore effectiveness of maxillomandibular advancement (MMA) in the treatment of obstructive sleep apnea/hypopnea syndrome (OSAHS). Methods MMA was performed in 10 OSAHS patients with mandibular dysplasia diagnosed by mandibular protrusion angle (SNB) 〈 75° and a posterior airway space (PAS) 〈 11 mm. Six patients had uvulopalatopharyngoplasty (UPPP) also. Six patients had over 6 months postoperative follow up. Resnlts The blood loss was about 250 -600 ml in the operation, and the serious complications didn't happen. The patients were satisfied with the postoperative facial change. Based on success criteria of 2009, of 5 patoents showed highly responsive result and 1 patient was responsive (valid). rate was 83% and the responsive rate 100%o. The snoring loudness score and Epworth sleepy score were reduced from preoperative 8(6 - 10) and 15( 11 -24) to postoperative 2(0 -4) and 5 (1 -8 ). AHI was reduced from preoperative 52. 2 (23.7 -83.8 ) to postoperative 12. 6 (7.6 -31.8 ), lowest mean oxygen saturation increased from 0.64 (0. 57 - 0.83 ) to 0.82 (0.78 - 0.93 ). Percentage of time with oxyhemoglobin saturation below 0. 90 (CT90) reduced from 21.0% (12. 0% -37.2% ) to 2. 0% (0% -8.0% ). Conclusions MMA is effective for the OSAHS patients with mandibular dysplasia.
