Abstract

Aim

To report the effect of oval and round window reinforcement surgery performed in two patients with the Tullio phenomenon. Case 1: A male with bilateral superior canal dehiscence syndrome. Downbeat nystagmus with leftward horizontal eye movement was recorded in an electronystagmogram using a pure-tone sound of 110 dB at 2000 or 4000 Hz in the right ear. Case 2: A female who had undergone stapes surgery. Computed tomography revealed an ossicular prosthesis in the vestibule. An audiogram indicated mild to moderate hearing impairment in the right ear. Leftward horizontal nystagmus was recorded in an electronystagmogram using a pure-tone sound of 110 dB at 500 or 1000 Hz in the right ear. Surgical findings indicated that the prosthesis was inserted deep into the oval window, which was closed with thin connective tissue.

Outcomes

After oval and round window reinforcement surgery was performed in the right ear, and loud, pure-tone sounds elicited neither nystagmus nor dizziness in either patient.
