mishaboo65 posted:
Middle ear myoclonus (MEM) is a rare diagnosis of tinnitus that is presumed secondary to abnormal movement of the tensor tympani or stapedius muscles. This diagnosis has been primarily used in case reports in the otolaryngology literature,1 where the phenomenology of the tinnitus, when described, is highly variable. MEM tinnitus is commonly characterized as clicking, suggested to be due the tensor tympani movement,2 or buzzing, suggested to be due to stapedius movement;3 however, it has also been described as throbbing, tapping, crackling like a grasshopper, bubbling, ticking, twitching, blowing, drum-like thumping, fluttering like a butterfly, whooshing or gushing.
