1 Name This is the Statement of Principles concerning otitis externa (Balance of Probabilities) (No. 26 of 2021). 2 Commencement This instrument commences on 25 January 2021. 3 Authority This instrument is made under subsection 196B(3) of the Veterans' Entitlements Act 1986. 4 Repeal The Statement of Principles concerning otitis externa No. 59 of 2012 (Federal Register of Legislation No. F2012L01803) made under subsections 196B(3) and (8) of the VEA is repealed. 5 Application This instrument applies to a claim to which section 120B of the VEA or section 339 of the Military Rehabilitation and Compensation Act 2004 applies. 6 Definitions The terms defined in the Schedule 1 - Dictionary have the meaning given when used in this instrument. 7 Kind of injury, disease or death to which this Statement of Principles relates (1) This Statement of Principles is about otitis externa and death from otitis externa. Meaning of otitis externa (2) For the purposes of this Statement of Principles, otitis externa: (a) means an infectious or non-infectious inflammation of the external auditory canal; and (b) includes: (i) acute diffuse otitis externa; (ii) acute localised otitis externa (furunculosis); (iii) eczematous otitis externa; (iv) malignant otitis externa; (v) acquired cholesteatoma of the external auditory canal; and (vi) otomycosis. Note 1: Otitis externa may be acute or chronic. Note 2: Typical symptoms of otitis externa include ear pain, pruritus, discharge and hearing loss. Note 3: Otitis externa may be accompanied by inflammation of the auricle. Note 4: otomycosis is defined in the Schedule 1 - Dictionary. (3) While otitis externa attracts ICD‑10‑AM code H60, H62.0, H62.1, H62.2, H62.3 or H62.4, in applying this Statement of Principles the meaning of otitis externa is that given in subsection (2). (4) For subsection (3), a reference to an ICD-10-AM code is a reference to the code assigned to a particular kind of injury or disease in The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM), Tenth Edition, effective date of 1 July 2017, copyrighted by the Independent Hospital Pricing Authority, ISBN 978-1-76007-296-4. Death from otitis externa (5) For the purposes of this Statement of Principles, otitis externa, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's otitis externa. Note: terminal event is defined in the Schedule 1 - Dictionary. 8 Basis for determining the factors On the sound medical‑scientific evidence available, the Repatriation Medical Authority is of the view that it is more probable than not that otitis externa and death from otitis externa can be related to relevant service rendered by veterans or members of the Forces under the VEA, or members under the MRCA. Note: MRCA, relevant service and VEA are defined in the Schedule 1 - Dictionary. 9 Factors that must exist At least one of the following factors must exist before it can be said that, on the balance of probabilities, otitis externa or death from otitis externa is connected with the circumstances of a person's relevant service: (1) participating in aquatic activities within the ten days before the clinical onset of otitis externa; Note: aquatic activities is defined in the Schedule 1 - Dictionary. (2) being exposed to hot and humid weather conditions or heavy rains, on at least ten days within the 30 days before the clinical onset of otitis externa; Note: hot and humid weather conditions is defined in the Schedule 1 - Dictionary. (3) undergoing a course of therapeutic radiation for cancer, where the affected ear was in the field of radiation, before the clinical onset of otitis externa; (4) having trauma to the external auditory canal of the affected ear within the ten days before the clinical onset of otitis externa; Note: Examples of trauma include a blunt or penetrating injury, a surgical procedure and blast force. (5) having a foreign object or implement inserted into, or removed from, the external ear canal of the affected ear within the ten days before the clinical onset of otitis externa; Note: An example of a foreign body or implement is an ear lavage instrument used for aural irrigation. (6) blocking the external auditory canal of the affected ear with an extrinsic aural device for a cumulative period of at least 16 hours within the seven days before the clinical onset of otitis externa; Note: extrinsic aural device is defined in the Schedule 1 - Dictionary. (7) having an acquired, persistent narrowing or obstruction of the external auditory canal of the affected ear at the time of the clinical onset of otitis externa; Note 1: Examples of causes of narrowing or obstruction of the external auditory canal include: (a) benign or malignant neoplasm; (b) cerumen accumulation; (c) exostosis of the external auditory canal; and (d) granuloma. Note 2: exostosis of the external auditory canal is defined in the Schedule 1 - Dictionary. (8) having an inflammatory skin disease at the time of the clinical onset of otitis externa, where the skin disease involves the external auditory canal of the affected ear; Note 1: Examples of an inflammatory skin disease include allergic or irritant contact dermatitis, seborrhoeic dermatitis, lichen planus, psoriasis and eczema. Note 2: Irritant or allergic contact dermatitis of the external auditory canal may be caused by shampoos, ototopical medications or accidental chemical splashes to the ear. (9) having an infectious, autoimmune or granulomatous disease at the time of the clinical onset of otitis externa, where the disease involves the external auditory canal of the affected ear; Note: Examples of an infectious, autoimmune or granulomatous disease include herpes zoster, relapsing polychondritis and sarcoidosis. (10) having chronic suppurative otitis media, involving the middle ear of the affected side, within the 30 days before the clinical onset of otitis externa; Note: chronic suppurative otitis media is defined in the Schedule 1 - Dictionary.
