Otosclerosis is a condition of the middle ear where portions of the dense enchondral layer of the bony labyrinth remodel into one or more lesions of irregularly-laid spongy bone. As the lesions reach the stapes the bone is resorbed , then hardened ( sclerotized ), which limits its movement and results in hearing loss , tinnitus , vertigo or a ...
Stapedectomy is a surgical procedure in which the stapes bone is removed from the middle ear and replaced with a prosthesis.. If the stapes footplate is fixed in position, rather than being normally mobile, the result is a conductive hearing loss.
Endoscopic ear surgery ... Otosclerosis is a disease that results in fixation of the stapes, which conducts sound to the inner ear. Microscopic stapedectomy, requires ...
Otosclerosis is a congenital or spontaneous-onset disease characterized by abnormal bone remodeling in the inner ear. Often this causes the stapes to adhere to the oval window, which impedes its ability to conduct sound, and is a cause of conductive hearing loss. Clinical otosclerosis is found in about 1% of people, although it is more common ...
Otology also includes surgical treatment of conductive hearing loss, such as stapedectomy surgery for otosclerosis. Neurotology (a related field of medicine and subspecialty of otolaryngology ) is the study of diseases of the inner ear, which can lead to hearing and balance disorders.
If absence or deformation of ear structures cannot be corrected, or if the patient declines surgery, hearing aids which amplify sounds are a possible treatment option. [3] Bone conduction hearing aids are useful as these deliver sound directly, through bone, to the cochlea or organ of hearing bypassing the pathology. These can be on a soft or ...
Otosclerosis; Congenital fixation of the stapes; Secondary surgical intervention to correct for a significant and persistent conductive hearing loss from prior otologic surgery; Surgically correctable injury to the middle ear from trauma
Whilst hearing loss is a common symptom in many diseases of the ear, for example in otosclerosis (abnormal bone growth in the ear), [3] the white, chalky patches on the tympanic membrane are fairly characteristic of tympanosclerosis. Cholesteatoma is similar in appearance but the whiteness is behind the tympanic membrane, rather than inside.
