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 ...
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.
Schwartz sign, also known as Flemingo's pink sign, is a diagnostic indicator for otosclerosis, a disease of the bones of the middle or inner ear. In clinical examination of the ear drum, increased vascularity of the promontory may be seen through the ear drum. This sign is known as Flemingo's flush sign or Schwartz's sign.
Otitis media is a group of inflammatory diseases of the middle ear. [2] One of the two main types is acute otitis media (AOM), [3] an infection of rapid onset that usually presents with ear pain. [1]
Stapedectomy has success rates ranging from 80% to 95%. [5] [6]Stapedectomy closes what is called the "air bone gap" very efficiently, meaning it restores efficient conduction of sound coming through the air close to the level of the best ability of the nerve cells to perceive the sound.
Otosclerosis, a disease of the ears. Primary lateral sclerosis, progressive muscle weakness in the voluntary muscles. Primary sclerosing cholangitis, a hardening of the bile duct by scarring and repeated inflammation.
The work that NICE is involved in, attracts the attention of many groups, including doctors, the pharmaceutical industry, and patients. NICE is often associated with controversy, because the requirement to make decisions at a national level, can conflict with what is (or is believed to be) in the best interests of an individual patient.
CT scan is useful in cases of congenital conductive hearing loss, chronic suppurative otitis media or cholesteatoma, ossicular damage or discontinuity, otosclerosis and third window dehiscence. Specific MRI scans can be used to identify cholesteatoma.
