OBJECTIVE: To describe 2 patients presenting with idiopathic tinnitus concomitant with eye closure.
STUDY DESIGN: Clinical capsule report.
SETTING: University hospital.
PATIENTS: 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.
INTERVENTIONS: 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.
CONCLUSION: 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.
