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 degrees and a posterior airway space (PAS) < 11 mm. Six patients had uvulopalatopharyngoplasty (UPPP) also. Six patients had over 6 months postoperative follow up.
Results:
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 patients showed highly responsive result and 1 patient was responsive (valid). rate was 83% and the responsive rate 100%. 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.
