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 ...
Fluid accumulation is the most common cause of conductive hearing loss in the middle ear, especially in children. [3] ... Otosclerosis, abnormal growth of ...
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.
In children with otitis media with effusion antibiotics may increase resolution of symptoms, but may cause diarrhoea, vomiting and skin rash. [13] Worldwide AOM affects about 11% of people a year (about 325 to 710 million cases). [14] [15] Half the cases involve children less than five years of age and it is more common among males.

Tympanic membrane retraction is fairly common and has been observed in one quarter of a population of British school children. [1] Retraction of both eardrums is less common than having a retraction in just one ear. It is more common in children with cleft palate. [2] Tympanic membrane retraction also occurs in adults. [3] [4]
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 ...
Stapedectomy and stapedotomy for otosclerosis - replacement or reshaping of the stapes bone of the middle ear can restore hearing in cases of conductive hearing loss; Surgical and implantable hearing aids are an alternative to conventional external hearing aids.
