What Researchers Did
Researchers described a case of recurrent subcutaneous emphysema in a 21-year-old man, investigating its cause and performing surgical repair.
What They Found
They found that a 21-year-old man experienced recurrent subcutaneous cervicofacial emphysema, initially 2 months after endotracheal intubation, with subsequent recurrences despite initial treatment. Investigation revealed five fistular tract orifices (two near the right vallecula, three at the epiglottis root) that allowed emphysema upon Valsalva's maneuver, which resolved completely within 4 days after surgical repair.
Canadian Relevance
This study has no direct Canadian connection as it is a case report from a non-Canadian institution.
Study Limitations
As a single case report, the findings may not be generalizable to a broader patient population.
