Tonic tensor tympani syndrome

The tonic tensor tympani syndrome is a disease of the tensor tympani muscle, described by Klochoff et al in 1971.[1][2] This is a decrease in the contraction threshold of tensor tympani. This hypercontraction (or spasms) leads to chronic ear pain and in particular in the case of hyperacusis [3] and acoustic shock.[4] These study opens an important understanding of the field of pain associated with hearing disorders.

Symptoms

Fullness in the ear, otalgia, tinnitus, dysacusis, tension headache and vertigo.[5]
