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 ...
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.
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.
Otosclerosis is a condition that can cause fixation of the stapes (or stirrup) in the middle ear preventing its movement and causing conductive hearing loss. Perilymph fistula – a microtear in either the round or oval window (membranes separating the middle and inner ear) of the cochlea causing perilymph to leak into the middle ear. This ...
Similar symptoms are also associated with other kinds of hearing loss; audiometry or other diagnostic tests are necessary to distinguish sensorineural hearing loss. Identification of sensorineural hearing loss is usually made by performing a pure tone audiometry (an audiogram) in which bone conduction thresholds are measured.
In general, the reason for ear pain can be discovered by taking a thorough history of all symptoms and performing a physical examination, without need for imaging tools like a CT scan. [3] However, further testing may be needed if red flags are present like hearing loss, dizziness, ringing in the ear or unexpected weight loss. [6]
The Rinne test (/ ˈ r ɪ n ə / RIN-ə) is used primarily to evaluate loss of hearing in one ear. [1] It compares perception of sounds transmitted by air conduction to those transmitted by bone conduction through the mastoid.
Only measures of static acoustic admittance, ear canal volume, and tympanometric width/gradient compared to sex, age, and race specific normative data can be used to somewhat accurately diagnose middle ear pathology along with the use of other audiometric data (e.g. air and bone conduction thresholds, otoscopic examination, normal word ...
