Acoustic neuroma
Meaning of acoustic neuroma: For the purposes of this Statement of Principles, acoustic neuroma: (a) means a benign neoplasm arising from Schwann cells of the vestibular or cochlear nerve; and (b) excludes acoustic neuroma associated with a tumour predisposition syndrome, such as neurofibromatosis or schwannomatosis.
Reasonable Hypothesis (RH) — Statement of Principles No. 96 of 2019
At least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting acoustic neuroma or death from acoustic neuroma with the circumstances of a person's relevant service:
- (1)having received a cumulative equivalent dose of at least 0.1 sievert of ionising radiation to the affected vestibular or cochlear nerve at least five years before the clinical onset of acoustic neuroma;
Note: cumulative equivalent dose is defined in the Schedule 1 - Dictionary.
- (2)inability to obtain appropriate clinical management for acoustic neuroma;
Aggravation-only factors: the factors in subsection 9(2) apply only to material contribution to, or aggravation of, the condition where it was suffered or contracted before or during (but did not arise out of) the person’s relevant service.
Balance of Probabilities (BoP) — Statement of Principles No. 97 of 2019
2 factors
At least one of the following factors must exist before it can be said that, on the balance of probabilities, acoustic neuroma or death from acoustic neuroma is connected with the circumstances of a person's relevant service:
- (1)having received a cumulative equivalent dose of at least 0.5 sievert of ionising radiation to the affected vestibular or cochlear nerve at least ten years before the clinical onset of acoustic neuroma;
Note: cumulative equivalent dose is defined in the Schedule 1 - Dictionary.
- (2)inability to obtain appropriate clinical management for acoustic neuroma;
Aggravation-only factors: the factors in subsection 9(2) apply only to material contribution to, or aggravation of, the condition where it was suffered or contracted before or during (but did not arise out of) the person’s relevant service.
