[Comparison of combined operation and nasal CPAP treatments for sleep disorders].
Uvulopalatopharyngoplasty (UPPP) and nasal CPAP are used for the treatment of obstructive sleep apnea syndrome (OSAS) in different institutions. Although OSAS results from an abnormality in the soft-palate, almost no reports have been made on the selection of UPPP or nasal CPAP procedures according to the type of abnormality. The most probable reason for this is that a comparison of treatment methods in individuals cases is difficult. We performed CPAP titration before and after operations, and compared the treatment methods, and evaluated the medical therapy.


METHODS
A sleep polygraph was performed on the first night, and cases diagnosed as OSAS received CPAP titration on the second night. The blocked region was identified by endoscopic examination. The results of the operation were evaluated after 1-2 months, and apnea hypopnea index (AHI) improvements of less than 50% received a second CPAP titration.


RESULTS
The operation results were poor for cases where endoscopic examination showed full-circumference palatal type, and good for soft palate and tonsillar type abnormalities. When endoscopic examinations were performed in conjunction with nasal CPAP, the treatment was observed to act on the soft palate and expand the air way in all cases. Nasal CPAP was effective in cases with full-circumference palatal abnormalities because in these cases, the pressure was caused by inflamma. Combined medical treatments were effective in cases where CPAP alone was ineffective because the pressure was too high.
