Objective: To present a case of a patient with visible stapedius contraction on vocalization and to discuss the related literature.

Patients: A 51 year-old woman with a Type III myringostapediopexy due to chronic suppurative otitis media and an incidental finding of voice-induced movement of the stapes head.

Interventions: Otoendoscopy, pure tone and impedance audiometry, and modified stapedius reflex decay.

Main Outcome Measure: Stapes head movement on otoendoscopy.

Results: Stapes head movement was seen endoscopically on vocalization but not on tympanometric measures.

Conclusion: Visible stapedius contraction with vocalization is an uncommon phenomenon. Our understanding of the nonauditory pathways to stapedius is limited and requires further research.

The middle ear muscles have vital roles, yet their precise function in hearing and protection remains unclear. To better understand the function of these muscles in humans, the morphology, fiber composition, and metabolic properties of nine tensor tympani and eight stapedius muscles were analyzed with immunohistochemical, enzyme-histochemical, biochemical, and morphometric techniques. Human orofacial, jaw, extraocular, and limb muscles were used as references.

Background: Stapes reflex test is a method of evaluating the involuntary muscle contraction of the stapedius muscle in response to a high-intensity sound stimulus. The formation of this reflex involves the intact function of the 7 nerve, brain stem, 8 nerve, and middle ear. Due to ease of administration and information yielded, the stapedial reflex is considered one of the most powerful differential diagnostic audiological procedures.

Middle ear myoclonus is a rare condition attributed to abnormal, repetitive contractions of the middle ear muscles including the tensor tympani and/or stapedius muscles. This condition generates objective tinnitus that is characterized by a "clicking" noise that is audible to both the patient and an outside observer. No specific pathophysiologic process has been identified as the cause of middle ear myoclonus, making its diagnosis and treatment challenging.

Middle ear muscle (MEM) abnormalities have been proposed to be involved in the development of ear-related symptoms such as tinnitus, hyperacusis, ear fullness, dizziness and/or otalgia. This cluster of symptoms have been called the Tonic Tensor Tympani Syndrome (TTTS) because of the supposed involvement of the tensor tympani muscle (TTM). However, the putative link between MEM dysfunction and the symptoms has not been proven yet and the detailed mechanisms (the causal chain) of TTTS are still elusive.
