Depending on length of symptoms, multinucleated giant cells and calcifications may be seen. Other disorders may be concurrently present, especially since this is a post infectious/inflammatory disorder, and these include a cholesterol granuloma, "tunnel clusters" (glandular epithelial inclusions below the surface epithelium), and cholesteatoma .
Balance symptoms in the presence of a cholesteatoma raise the possibility that the cholesteatoma is eroding the balance organs in the inner ear. [1] Doctors' initial inspections may only reveal an ear canal full of discharge. Until the doctor has cleaned the ear and inspected the entire tympanic membrane, cholesteatoma cannot be diagnosed. [2]
Computerised tomography (CT) can be used to determine if disease is present in the middle ear. [12] 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 ...
Endolymphatic hydrops is a disorder of the inner ear. It consists of an excessive build-up of the endolymph fluid, which fills the hearing and balance structures of the inner ear. Endolymph fluid, which is partly regulated by the endolymph sac, flows through the inner ear and is critical to the function of all sensory cells in the inner ear.
If medical management fails, myringotomy, which is a surgical procedure in which an incision is made in the eardrum to drain pus from the middle ear or to relieve pressure caused by a large buildup of fluid, is indicated, and usually accompanied by the insertion of a tympanostomy tube. [10]
The vestibular aqueduct acts as a canal between the inner ear and the cranial cavity. Running through it is a tube called the endolymphatic duct, which normally carries a fluid called endolymph from the inner ear to the endolymphatic sac in the cranial cavity. When the endolymphatic duct and sac are larger than normal, as is the case in large ...
Medical research on the function of ear hair is currently very scarce. Hair growth within the ear canal is often observed to increase in older men, [3] together with increased growth of nose hair. [4] Excessive hair growth within or on the ear is known medically as auricular hypertrichosis. [5]
Ear hair protruding from the external auditory meatus in a middle-aged male. Ear hair is the terminal hair arising from folliculary cartilage inside the external auditory meatus in humans. [ 1 ] In its broader sense, ear hair may also include the fine vellus hair covering much of the ear, particularly at the prominent parts of the anterior ear ...
