The tensor tympani is a muscle within the middle ear, located in the bony canal above the bony part of the auditory tube, and connects to the malleus bone. Its role is to dampen loud sounds, such as those produced from chewing, shouting, or thunder.
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 ...
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.

The stapedius muscle, the smallest skeletal muscle in the body, connects to the stapes and is controlled by the facial nerve; the tensor tympani muscle is attached to the upper end of the medial surface of the handle of malleus [2] and is under the control of the medial pterygoid nerve which is a branch of the mandibular nerve of the trigeminal ...
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.
The medial pterygoid nerve supplies the medial pterygoid muscle, tensor tympani muscle, and tensor veli palatini muscle (via the nerve to tensor veli palatini). [1] The tensor veli palati muscle is the only of the five paired skeletal muscles to the soft palate not innervated by the pharyngeal plexus. [citation needed]
"It is bad to lose muscle instead of fat, because muscles are the key players in body movement and function," says Gerardo Miranda-Comas, M.D., Assistant Professor of Rehabilitation Medicine ...
A superior tympanic artery runs in the canal of the tensor tympani muscle, and supplies this muscle and the lining of the canal. Orbital branches pass through the superior orbital fissure or through separate canals in the great wing of the sphenoid, to anastomose with the lacrimal or other branches of the ophthalmic artery.
