Sinus barotrauma
Meaning of sinus barotrauma: For the purposes of this Statement of Principles, sinus barotrauma means an injury to a paranasal sinus arising from inequalities in the barometric pressure between the surrounding atmosphere and the air within the sinus cavity.
Reasonable Hypothesis (RH) — Statement of Principles No. 23 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 sinus barotrauma or death from sinus barotrauma with the circumstances of a person's relevant service:
- (1)experiencing a change in the ambient barometric pressure as specified, within the 24 hours before the clinical onset of sinus barotrauma;
Note: change in the ambient barometric pressure as specified is defined in the Schedule 1 - Dictionary.
- (2)receiving mechanical ventilation involving a face mask within the 24 hours before the clinical onset of sinus barotrauma;
Note: mechanical ventilation is defined in the Schedule 1 - Dictionary.
- (3)being exposed to an explosive blast within the 24 hours before the clinical onset of sinus barotrauma;
- (4)having impaired drainage of the sinus within the 24 hours before the clinical onset of sinus barotrauma;
Note: impaired drainage of the sinus is defined in the Schedule 1 - Dictionary.
- (5)having allergic rhinitis or sinusitis within the 24 hours before the clinical onset of sinus barotrauma;
- (6)experiencing a change in the ambient barometric pressure as specified, within the 24 hours before the clinical worsening of sinus barotrauma;
Note: change in the ambient barometric pressure as specified is defined in the Schedule 1 - Dictionary.
- (7)receiving mechanical ventilation involving a face mask within the 24 hours before the clinical worsening of sinus barotrauma;
Note: mechanical ventilation is defined in the Schedule 1 - Dictionary.
- (8)being exposed to an explosive blast within the 24 hours before the clinical worsening of sinus barotrauma;
- (9)having impaired drainage of the sinus within the 24 hours before the clinical worsening of sinus barotrauma;
Note: impaired drainage of the sinus is defined in the Schedule 1 - Dictionary.
- (10)having allergic rhinitis or sinusitis within the 24 hours before the clinical worsening of sinus barotrauma;
- (11)inability to obtain appropriate clinical management for sinus barotrauma;
Aggravation-only factors: the factors in subsections 9(6) to 9(11) 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. 24 of 2019
11 factors
At least one of the following factors must exist before it can be said that, on the balance of probabilities, sinus barotrauma or death from sinus barotrauma is connected with the circumstances of a person's relevant service:
- (1)experiencing a change in the ambient barometric pressure as specified, within the 24 hours before the clinical onset of sinus barotrauma;
Note: change in the ambient barometric pressure as specified is defined in the Schedule 1 - Dictionary.
- (2)receiving mechanical ventilation involving a face mask within the 24 hours before the clinical onset of sinus barotrauma;
Note: mechanical ventilation is defined in the Schedule 1 - Dictionary.
- (3)being exposed to an explosive blast within the 24 hours before the clinical onset of sinus barotrauma;
- (4)having impaired drainage of the sinus within the 24 hours before the clinical onset of sinus barotrauma;
Note: impaired drainage of the sinus is defined in the Schedule 1 - Dictionary.
- (5)having allergic rhinitis or sinusitis within the 24 hours before the clinical onset of sinus barotrauma;
- (6)experiencing a change in the ambient barometric pressure as specified, within the 24 hours before the clinical worsening of sinus barotrauma;
Note: change in the ambient barometric pressure as specified is defined in the Schedule 1 - Dictionary.
- (7)receiving mechanical ventilation involving a face mask within the 24 hours before the clinical worsening of sinus barotrauma;
Note: mechanical ventilation is defined in the Schedule 1 - Dictionary.
- (8)being exposed to an explosive blast within the 24 hours before the clinical worsening of sinus barotrauma;
- (9)having impaired drainage of the sinus within the 24 hours before the clinical worsening of sinus barotrauma;
Note: impaired drainage of the sinus is defined in the Schedule 1 - Dictionary.
- (10)having allergic rhinitis or sinusitis within the 24 hours before the clinical worsening of sinus barotrauma;
- (11)inability to obtain appropriate clinical management for sinus barotrauma;
Aggravation-only factors: the factors in subsections 9(6) to 9(11) 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.
