Laser-assisted uvulopalatoplasty is well established and relatively successful operation in the treatment of snoring and obstructive sleep apnea (OSA). But, there have been no reports about snoringsound of patientswho had been performed LAUP. This study was performed to evaluate the results of LAUP analysing preoperative snoringsounds. MATERIALS AND
METHODS:
There were 38 patientswho were diagnosed as OSA by polysomnography and had been performed LAUP between Mar, 1998 and July, 2002. Preoperative and postoperative snoringsounds were recorded during sleep and we performed an acousticanalysis using spectrogram (SPG), which was classified. And postoperative subjective satisfaction of bedtime partner was compared in each type and the degree of satisfaction was measured by VAS (visual analogue scale) score. According to previous study, types of spectrogram of snoringsounds were classified as palatal, tongue base and mixed.
RESULTS:
In postoperative analysis, snoring loudness was most decreased in palatal type, and snoring pitch was only increased in tongue base type. The average satisfaction of bedtime partner was highest at palatal type and lowest at tongue base type.
