Auris Nasus Larynx
Tinnitus can be generated by various causes, including vascular or myogenic factors and sensorineural auditory structures. Tinnitus due to repetitive contraction of the paraauditory muscles is a rare condition. We present a case of bilateral tinnitus concomitant with eyelid blinking. Otoscopy revealed normal tympanic membranes; however, inward movement of the tympanic membrane was visible whenever the patient blinked. Long-time-based tympanometry measuring static compliance revealed a cogwheel or saw-toothed pattern associated with movement of the tympanic membrane related to eyelid blinking. The patient was managed with pharmacological treatment combined with assurance and was relatively well controlled.
