Idiopathic tinnitus concomitant with eye closure.
OBJECTIVE
To describe 2 patients presenting with idiopathic tinnitus concomitant with eye closure.


METHODS
Clinical capsule report.


METHODS
University hospital.


METHODS
Two patients presented with intermittent tinnitus synchronous with eye closing or blinking. Otoscopic examination revealed inward movement of tympanic membranes concomitantly with eye blinking or eye closure in 1 patient. Neither patient had facial nerve disease or myoclonus.


METHODS
Compliance in impedance audiometry was recorded.


RESULTS
Compliance in impedance audiometry was reduced during eye blinking and eye closure in both cases. The tinnitus was attributed to muscular tinnitus via stapedial muscle contraction during eye closure.


CONCLUSIONS
These are the rare 2 reported patients presenting with idiopathic muscular tinnitus concomitant with eye closure. The reductive change of compliance in impedance audiometry during tinnitus coincident with eye closure is a feature of this form of tinnitus. We suggest evaluation of compliance change in impedance audiometry to be a key examination in patients with stapedial muscular tinnitus concomitant with eye closure.
