A stapes mobilization is a surgical procedure aimed at restoring the movement of the stapes bone, which is one of the three tiny bones in the middle ear responsible for transmitting sound vibrations to the inner ear. Under normal circumstances, the stapes vibrates freely, allowing sound waves to be effectively conducted. However, in certain conditions, particularly otosclerosis, the stapes can become fixed due to abnormal bone growth on the walls of the inner ear. This fixation leads to conductive hearing loss, as the sound transmission is impeded. The procedure begins with an incision made in the posterior aspect of the external ear canal wall, followed by the creation of a tympanomeatal flap. This flap is then elevated to expose and inspect the ossicles of the middle ear. During the stapes mobilization, a specialized hook is utilized, which is placed against the long process of the incus. The hook is maneuvered towards the stapes tendon to release any attachments that may be causing the stapes to be fixed in place. After the mobilization is successfully completed, the tympanomeatal flap is repositioned, and the incision in the meatus is closed with sutures, ensuring proper healing and restoration of function.
