title: [A case of sleep apnea syndrome due to a nasopharyngeal tumor].
abstract: Obstructive Sleep Apnea Syndrome (OSAS) is children is commonly caused by upper airway obstruction, such as that caused by adeno-tonsillar hypertrophy. We report a rare case of SAS due to a nasopharyngeal tumor. The patient was a 10-year-old boy who complained of snoring and sleep apnea. The tumor was found in the nasopharynx and mesopharyngeal space. We diagnosed this case as OSAS by overnight sleep study (Apnea Hypopnea Index: AHI = 19.67). The tumor was removed under general anesthesia. Histopathology revealed features of nasopharyngeal angiofibroma. After removal of the tumor, his symptoms resolved completely. A follow-up overnight sleep study confirmed resolution of OSAS. At the last follow up, conducted 17 months after the operation there were no signs of tumor recurrence.
