A Novel Technique for the Diagnosis and Management of Middle Ear Myoclonus.

A novel technique for the diagnosis and management of middle ear myoclonus is described. A patient with middle ear myoclonus underwent a trans-canal microscopic middle ear exploration with injection of botulinum toxin into the stapedius and tensor tympani muscles. Postoperatively, the patient noted complete resolution of symptoms. This is the first report of the use of botulinum toxin directly applied to the middle ear musculature via a trans-canal approach for the management of middle ear myoclonus. This approach is both a useful diagnostic and therapeutic tool that allows for temporary muscle paralysis prior to offering definitive surgical management. Laryngoscope, 131:E248-E249, 2021.
