Evaluation of uvulopalatopharyngoplasty in treatment of obstructive sleep apnea syndrome.
Many methods have been reported to select the proper candidates for uvulopalatopharyngoplasty (UPPP) among obstructive sleep apnea patients. Polysomnography with intraluminal pressure recordings in the upper airway was found useful to predict obstructive site(s) and hence the success of surgery. According to the pressure analysis, 11 cases with high negative pressure at the mesopharynx were selected for UPPP, while UPPP combined with midline partial glossectomy (UPPP-MLG) was done in 18 cases proved to have high negative pressure difference between the mesopharynx and esophagus. A reduction of the apnea hypopnea index (AHI) of more than 50% after UPPP was found in 8 cases (72.7%) and in 11 cases (61.l%) after UPPP-MLG. It was found that the response rate was lower among the second group if compared to that of the first because of other aggravating factors rather than simple obstruction at the level of the soft palate and or tonsils-tongue base level.
