Following the joint disarticulation, the stapedius

Preserving the stapedius

(Cristell, Hutchinson, & Alessio, 1998)Increased body temperature and release of chemical substances, which cause the changes in metabolic activity, (Lindgren & Axelsson, 1988)possible inhibition of the stapedius
reflex during exercise (Colletti et al., 1991)have been suggested as possible explanations.
Acoustic immittance test showed A-shaped tympanometry curves of both ears as well as normal acoustic reflex thresholds of ipsilateral and crossed stapedius
Cochleostapedial reflex is acoustic reflex produced by contraction of the stapedius
muscle and used in topographical diagnosis of facial nerve pathology.
muscle reflex in mercury-exposed Andean children and adults.
Besides, many studies use contralateral elicitors and do not include measures to discard the influence of stapedius
muscle contractions [12,13].
In addition, low-frequency conductive hearing loss or hyperacusis of bone conduction in pure tone audiometry (PTA) with normal findings on tympanometry, acoustic stapedius
reflex, and Gelle's test may also lead to a positive SSCD diagnosis.
The middle ear contains ossicles, nerves and muscles (stapedius
and tensor tympani).
As acoustic reflex test implies the intensity of stapedius
through movement of tympanic membrane through generation of a loud sound.
Otologic assessment included micro-otoscopy, pure-tone audiometry, tympanometry, and stapedius
reflex measurement to verify normal middle ear function.
