Objective Tinnitus Concomitant with Eye Blinking: A Case Report.

Kim TH, Jang HJ, Park SH, Nam SI - J Audiol Otol (2015)

Bottom Line: We present a rare case of intermittent unilateral tinnitus associated with eye blinking.Otoendoscopic examination showed that the external auditory canals and tympanic membranes were normal; however, rhythmic movements of both tympanic membranes, concomitant with the tinnitus, were evident whenever the patient blinked.The tympanometry and stapedial reflexes measured via impedance audiometry exhibited saw-tooth patterns; movement of the tympanic membrane was associated with eyelid blinking.

ABSTRACT
Tinnitus is a common auditory phenomenon associated with many otological diseases, and is usually subjective. Objective tinnitus can be generated by para-auditory structures, usually derived from vascular or myogenic sources, or the eustachian tube. We present a rare case of intermittent unilateral tinnitus associated with eye blinking. Otoendoscopic examination showed that the external auditory canals and tympanic membranes were normal; however, rhythmic movements of both tympanic membranes, concomitant with the tinnitus, were evident whenever the patient blinked. The tympanometry and stapedial reflexes measured via impedance audiometry exhibited saw-tooth patterns; movement of the tympanic membrane was associated with eyelid blinking. The patient was managed conservatively, with reassurance and medication, and the condition became well-controlled. Here, we present this educational case and review the literature.

Figure 3: Acoustic reflex decay showed (A) no perturbation without eye blinking and (B) sharp, irregular perturbation with eye blinking.

Mentions: Pure tone audiometry showed that the hearing threshold was normal. Both tympanograms were of type A; the middle-ear pressure was normal when the patient did not blink (Fig. 2A). However, and interestingly, saw-tooth patterns associated with tympanic membrane movement were obtained during blinking (Fig. 2B). Acoustic reflex decay revealed irregular perturbations synchronous with eyelid blinking (Fig. 3). The tinnitus was considered to be attributable to stapedial muscle contraction, based on the reductive change in impedance audiometry compliance during blinking. The auditory brainstem response was normal. Temporal bone computed tomography (CT) revealed no abnormal lesion such as trauma, infection, or a vascular or neoplastic disease.
