What Researchers Did
Researchers evaluated ear, nose, and throat (ENT) morbidity by examining serving soldiers presenting with ENT symptoms in a high-altitude environment and patients undergoing related therapies.
What They Found
The study detected 13 cases of otic barotrauma, 11 cases of sinus barotrauma, 3 cases of vertigo, and 6 cases of pinna frostbite among soldiers at high altitude. Additionally, 3 cases of barotrauma from hyperbaric chamber therapy, an unusually high incidence of epistaxis, and numerous cases of high altitude pharyngitis were observed.
Canadian Relevance
While this study was not conducted in Canada, its findings are relevant for Canadian military personnel deployed to high-altitude regions and for Canadian civilians who travel or engage in activities at high altitudes.
Study Limitations
The study's findings are limited by its focus on a specific military population and lack of a control group, which may affect generalizability.
