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.

Preliminary questions [13078]

13661 there is some evidence that otosclerosis may be a factor in the development or worsening of the condition under consideration.

13127 the veteran has suffered from otosclerosis at some time.

13130  the veteran has established the causal connection between the otosclerosis and VEA service for tinnitus.

13129 the veteran was suffering from otosclerosis at the time of the clinical onset of the condition under consideration.

13131   the veteran has established the causal connection between the otosclerosis and VEA service for the clinical onset of tinnitus.

30392  the veteran has established the causal connection between the otosclerosis and operational service for the clinical onset of tinnitus.

or

30393  the veteran has established the causal connection between the otosclerosis and eligible service for the clinical onset of tinnitus.

or

7334     the clinical onset of the condition under consideration occurred after the end of the veteran's last period of VEA service.

7335     the condition under consideration permanently worsened.

30391 the veteran was suffering from otosclerosis at the time of the clinical worsening of the condition under consideration.

13132   the veteran has established the causal connection between the otosclerosis and VEA service for the clinical worsening of tinnitus.

30394  the veteran has established the causal connection between the otosclerosis and operational service for the clinical worsening of tinnitus.

or

30395  the veteran has established the causal connection between the otosclerosis and eligible service for the clinical worsening of tinnitus.

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.
