The most common procedure for tonic tensor tympani syndrome is tympanotomy with tensor tympani tenotomy. This is a relatively simple surgical procedure that involves endoscopically cutting the tensor tympani muscle to eliminate spasms. A tensor tympani tenotomy is the preferred method of treatment due to being a safe and reliable procedure with ...
In many people with hyperacusis, an increased activity develops in the tensor tympani muscle in the middle ear as part of the startle response to some sounds. This lowered reflex threshold for tensor tympani contraction is activated by the perception/anticipation of loud sound, and is called tonic tensor tympani syndrome (TTTS). In some people ...
Of note, the tensor tympani muscle is innervated by the trigeminal nerve. The model also explains how whiplash injuries, temporomandibular joint dysfunction, and other conditions affecting the head and neck regions may influence the function of the tensor tympani muscle and contribute to ear symptoms such as pain hyperacusis.

Acamprosate has been successfully used to control tinnitus, hyperacusis, ear pain, and inner ear pressure during alcohol use due to spasms of the tensor tympani muscle. [medical citation needed] In addition, alcohol also inhibits the activity of N-methyl-D-aspartate receptors (NMDARs).
It has been suggested that the tensor tympani is involved in causing the disorder (see tonic tensor tympani syndrome). [6] [7] In France, researchers report the study of a case of acoustic shock in a scientific publication. They suggest that these symptoms may result from a loop involving the middle ear muscles, peripheral inflammatory ...
Some forms appear to be stimulus-sensitive. Some people with sleep myoclonus are rarely troubled by it, or need treatment. If it is a symptom of more complex and disturbing sleep disorders, such as restless legs syndrome, it may require medical treatment. Myoclonus can be associated with patients with Tourette syndrome.
The tensor tympani arises from the cartilaginous portion of the auditory tube and the osseous canal of the sphenoid and, having sharply bent over the extremity of the septum, attaches to the manubrium of the malleus (hammer); its contraction pulls the malleus medially, away from the tympanic membrane, which tenses the membrane.
The acoustic reflex (also known as the stapedius reflex, [1] stapedial reflex, [2] auditory reflex, [3] middle-ear-muscle reflex (MEM reflex, MEMR), [4] attenuation reflex, [5] cochleostapedial reflex [6] or intra-aural reflex [6]) is an involuntary muscle contraction that occurs in the middle ear in response to loud sound stimuli or when the person starts to vocalize.
