Tinnutis - Otosclerosis Factor
In the Statement of Principles for Tinnitus the RMA has defined otosclerosis as "a primary disorder of the labyrinthine capsule, characterised by new bone formation commonly involving the footplate of the stapes." The stapes [also called the stirrup] is one of the 3 small bones in the middle ear which conduct vibrations from the tympanic membrane to the inner ear.
The tendency to otosclerosis is familial and it becomes clinically evident in the late teenage and early adult years. About 10% of affected persons develop hearing loss.

Clinical onset and operational service [30392]
30468 the otosclerosis is causally related to operational service.
Clinical onset and eligible service [30393]
30469 the otosclerosis is causally related to eligible service.
Clinical worsening and operational service [30394]
30468 the otosclerosis is causally related to operational service.
30396 the clinical onset of the condition under consideration occurred prior to that part of operational service to which the otosclerosis is causally related.
Clinical worsening and eligible service [30395]
30469 the otosclerosis is causally related to eligible service.
30397 the clinical onset of the condition under consideration occurred prior to that part of eligible service to which the otosclerosis is causally related.
