What Researchers Did
Researchers investigated thermal myringotomy as an alternative to tympanostomy tube placement for eustachian tube dysfunction in 13 patients undergoing hyperbaric oxygen therapy.
What They Found
At five weeks post-operation, 96% of the myringotomies remained patent, providing adequate ventilation for most hyperbaric oxygen courses. The persistent perforation rate at six months was 15%, and only 1 patient experienced otorrhea, which resolved with dry ear precautions.
What This Means for Canadian Patients
This suggests thermal myringotomy could offer a temporary and less invasive solution for Canadian patients experiencing eustachian tube dysfunction during hyperbaric oxygen therapy. It may reduce the need for long-term indwelling tubes and their associated higher complication rates.
Canadian Relevance
This study does not have a direct Canadian connection.
Study Limitations
A limitation of this study is its small sample size of 13 patients.
