Abstract:

Objective   To investigate the effect of  one stage multiplanar operation for the obstructive sleep apnea hypoventilation syndrome(OSAHS). Mehods   68 cases with nasal、 palatopharyngeal and oropharyngeal obstruction received H-uvulopalatopharyngoplasty(H-UPPP), nasal reconstruction and hyoid suspension. Before the operation, some severe cases underwent continuous positive airway pressure(CPAP) therapy or tracheotomy. Results   In 68 cases, all the  operations were performed successfully. No death or  severe complications occurred during the operation and follow-up. According to  polysomnography(PSG), the effectiveness was 100%  6 months later and 95.55% after one year. 6 months and one year after the operation, the changes of AHI and SaO2 were  significant (P<0.05) compared with those  preoperative. On CT scanning, the anteroposter dimensions of retroglossal areas were decreased, and retropalatal areas were increased after surgery (P<0.05). The shape of airway was improved  significantly. Conclusion   The one stage multiplanar operation is safe and effective for OSAHS. The shape of airway tends to be normal . CPAP before the operation can  effectively  prevent postoperative severe complications.
