Auricular Myoclonus: A Case Report and Literature Review

Auricular myoclonus is an extremely rare disorder that manifests as involuntary semi-rhythmic movements of the auricle. We report the case of a 15-year-old female who presented to our outpatient clinics with bilateral spontaneous, uncontrolled movements of the auricles (auricular myoclonus) that are only briefly suppressible by some facial movements and completely disappear during sleep. Needle electromyography revealed baseline tonic motor unit activity with bursts of higher motor units amplitude in the posterior and superior auricularis muscles. Her symptoms improved with pregabalin intake, however, with incomplete resolution. This paper will review previously reported cases, as well as the different treatment modalities that have been used.

“…Three major muscles located around the auricle, namely the anterior, superior, and posterior auricular muscles, are functionally vestigial in humans. Previous studies have shown that ear movement disorders can successfully be treated with botulinum toxin injections [2,5,7]; however, to date, there have been no reports on surgical treatment. Herein, we report a patient with auricular dystonia, which was refractory to botulinum toxin injections, who was successfully treated with unilateral pallidothalamic tractotomy.…”

Background: Ear movement disorders are rarely reported. Although some patients may respond to botulinum toxin injections, reports on surgical treatment options remain limited. Case Report: A 57-year-old woman was diagnosed with auricular dystonia, which was refractory to botulinum toxin injections. Since involuntary movement and pain were predominantly present on the right side and the patient rejected the implantation of a mechanical device, we decided to perform left pallidothalamic tractotomy. Immediately following lesioning, bilateral ear movements and right auricular pain ceased with no complications. Discussion: Stereotactic neurosurgical treatment can be an alternative for auricular dystonia. Highlights: Ear movement disorders, such as auricular myoclonus or dystonia, are rarely reported. The present case was refractory to repetitive botulinum toxin injections and oral medications. To the best of our knowledge, this is the first case of auricular dystonia that successfully improved with stereotactic neurosurgical treatment (pallidothalamic tractotomy).

“…Ear aurical muscle myoclonusis an extremely rare phenomenon. Publications define it with various terms: ear tic, moving ear syndrome, muscle dystonia, ear dyskinesia [23][24][25][26][27]. Ear aurical muscle myoclonus, as it appears from one of the titles, is often accompanied by its evident rhythmical movement, yet as a rule it disappears at bedtime and at breath hold [10].…”

Myoclonus of the Auricular Muscles as the Cause of Objective Tympanophonia

The objective of the present article was to systematize the available data on the etiology, pathogenesis, clinical features, diagnostics and treatment of muscular tympanophonia. The common sourse of muscular tympanophonia is the tremor (myoclonus) of the soft palate or muscles of auditory ossicles. Sometimes this condition can be a consequence of myoclonus of the external ear muscles. Pharmacotherapy of muscular tympanophonia does not invariably result in the favourable outcome. The authors describe a rare observation of objective tympanophonia attributable to myoclonus of auricular muscle. Abbreviations: MEM: Middle Ear Myoclonus. Muscle tympanophony typically results from palatal tremor (myoclonus) or middle ear myoclonus. However there are a few descriptions of tympanophony associated with eyelid movement [7], ear outer muscle myoclonus (M. auricularis anterior, superior, posterior), and head Editorial Volume 3 Issue 2
