Large nasopharyngeal inverted papilloma presenting with rustling tinnitus.

Tinnitus is a common symptom caused by numerous diseases. The etiology is unknown in most cases; however, nasopharyngeal lesions may cause a certain tinnitus. We herein report a case of nasopharyngeal inverted papilloma which presents with rustling tinnitus as the sole initial symptom. The tympanic membrane was intact, and results of hearing test and impedance audiometry were normal. However, sonotubometry showed a complete blockage of the Eustachian tube. A large tumor was found that originated from the choana and occupied the nasopharynx which caused a rustling sound when she swallowed or spoke. Tinnitus totally subsided after removal of this tumor. To our knowledge, the tumor origin and presenting symptom of this case are very rare, and nasopharyngeal examination is required in the diagnosis of unknown hearing symptoms.
