Impaired drainage of the sinus Factor
The RMA defines Impaired drainage of the sinus to mean one of the following which leads to a narrowing or obstruction of the affected sinus or sinus opening:
(a) an anatomical deformity including deviated septum, enlarged turbinates, adenoidal hypertrophy, fracture of the nasal bones or any other bony structural abnormalities; or
(b) a soft tissue abnormality or mucosal swelling affecting the sinus including polyps, tumours, inflammation, sarcoidosis, granulomas, or scarring; or
(c) a foreign body including nasal packing, naso-gastric or naso-tracheal tubes, dental detritus.
In CCPS
If the veteran’s impaired drainage of the sinus is the result of one of the medical conditions listed in parts (a) or (b) of the RMA definition, then the Impaired drainage of the sinus factor should be investigated. This factor should also be used where the impaired drainage is caused by nasal packing, or the use of naso-gastric or naso-tracheal tubes during treatment for another medical condition (other than chronic sinusitis).
If the impaired drainage of the sinus results from the presence of a foreign body (e.g. shrapnel) during service, other than as a result of surgery or other treatment, then the Impaired drainage of the sinus due to an event on service factor should be investigated.
Establishing onset
You may need to seek medical advice to determine whether or not a veteran has ever suffered from impaired drainage of the sinus.
If a veteran or member had impaired drainage of the sinus he or she would probably have needed medical attention at some time. Such medical treatment would normally be recorded in doctors' notes and/or hospital records. However, these records may have been destroyed or can no longer be obtained. Therefore, if there is a reliable history of appropriate medical treatment at a particular time, this generally will be accepted, providing this is not negated by other evidence.
