Abstract: To explore the complications that happened after uvulopalatopharyngoplasty (UPPP) combined with hyoid suspension for obstructive sleep apnea hyperventilate syndrome (OSAHS) patients. MethodsFrom January 2003 to June 2008, 109 (98 males and 11 females) cases of severe OSAHS were treated with UPPP. All patients were checked with a fiber optic laryngoscope of Muller and X-ray or CT for upper air flue when they were in a waking state to locate the collapse level (oropharyngeal and palatopharyngeal level, most of them had an obstruction on the oropharyngeal level). After the UPPP, they were sent to the ICU and monitored with trachea cannula for 1 to 2days. ResultsThe lower perforated edge of the inferior maxilla mangled by the thread for the hole was too low in 1 case. Incisions on the neck were fat liquoring in 6 cases. 3 cases had repeated inflammation, which was probably because the incision was irritated by the suture. 2 cases had bleeding from the incision. All had discomfort sensation on the pharyngeal and glossal portion, and movement of the tongue was constrained for 2-4 days and became normal after 5-7days. ConclusionHyoid suspension has few complications and is simple, safe and effective for OSAHS with an oropharyngeal level collapse.
