Objective Tinnitus Concomitant with Eye Blinking: A Case Report

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.

Endoscopic Treatment of Middle Ear Myoclonus with Stapedius and Tensor Tympani Section: A New Minimally-Invasive Approach.

Aims: We describe a new, entirely endoscopic surgical technique for treatment of middle ear myoclonus. Case Presentation: In our patient, the stapedius and tensor tympani tendons were sectioned to control chronic middle ear myoclonus. The procedure was performed using endoscopic ear surgery techniques, with the aid of rigid Hopkins rod endoscopes. Control of the pulsatile tinnitus was achieved after endoscopic tenotomy of the stapedius and tensor tympani, without any complications. Discussion and Conclusion: Endoscopic tensor tympani and stapedius tendon section is a new, minimally invasive treatment option for middle ear myoclonus that should be considered as a first line surgical approach in patients who fail medical therapy. The use of an endoscopic approach allows for easier access and vastly superior visualization of the relevant anatomy, which in turn allows the surgeon to minimize dissection of healthy tissue for exposure. The entire operation, including raising the tympanomeatal flap and tendon section can be safely completed under visualization with a rigid endoscope with good control of the pulsatile tinnitus.

One Case of Objective Tinnitus due to Palatal and Middle Ear Myoclonus / 대한이비인후과학회지

Tinnitus is very frequent and internal noise that impaires the quality of life. Objective tinnitus, which may be caused by palatal and middle ear myoclonus, is an extremely rare disorder. Such tinnitus may present very rapid, irregular and involuntary vibratory sound. Because it is a very rare disorder and patients have difficulty expressing their symptoms of tinnitus, the examiner may miss the diagnosis unless a careful history taking and physical examination is done. We have experienced a patient with objective tinnitus caused by both palatal myoclonus and middle ear myoclonus, who responded poorly to medical therapy and injection of botulinum toxin. However, this patient is treated with pterygoid hamulus fracture and sectioning of the tensor tympani and stapedial tendons. We report a review of the literature and present a case of a 26-year old man who did not respond to medical treatment and had to be relieved of the symptoms with surgical intervention.
