Is tensor tympani control rare?
Voluntary control over the tensor tympani muscle is an extremely rare event. However, an understanding of the potential audiometric effects of its contraction could aid the diagnosis of hearing disorders.
Are ears involuntary muscles?
Involuntary control (tympanic reflex) The reflex works by contracting the muscles of the middle ear, the tensor tympani and the stapedius. This pulls the manubrium of the malleus inwards and tightens it. This tightening prevents the vibrations from disturbing the perilymph.

The helicis minor is an oblique fasciculus, covering the crus helicis.
What happens when the muscles in the middle ear spasm?
When these muscles spasm, the result can be middle ear myoclonus (MEM), also known as MEM tinnitus. MEM is a rare condition — occurring in about 6 of 10,000 people — in which tinnitus (buzzing or ringing in ears) is produced by repetitive and synchronized contractions of the tensor tympani and stapedius muscles.
