Study on the Short-Time Remolding of Upper Airway After Uvulopalatopharyngoplasty.

Objective: To verify the short-time remolding of upper airway in patients diagnosed with obstructive sleep disordered breathing after Uvulopalatopharyngoplasty (UPPP). Methods: Twenty-one male adult patients aged 27 to 52 years followed up ranged from preoperation to 6 months after the operation. Lateral cephalometric radiographs (conventional and when pronouncing "i") were obtained 2 weeks preoperatively, 3 days postoperatively, and 1, 2, 3, 6 months after the surgery. The anterolateral diameters of different levels of upper airway and parameters of hyoid position of the patients were then measured. SAS 8.02 was used to analyze the differences by time. Results: The study illustrated that the UPPP major affected the velopharyngeal and glossopharyngeal areas: parameters wane (P 0.05) while the velopharyngeal parameters were increasing (P
