What Researchers Did
Researchers retrospectively analyzed 42 diabetic patients with necrotizing otitis externa, comparing those treated with antibiotics alone (23 cases) to those receiving antibiotics plus hyperbaric oxygenotherapy (19 cases).
What They Found
The study included 42 diabetic patients with a mean age of 67 years. Patients receiving hyperbaric oxygenotherapy (HOT) experienced faster resolution of symptoms, with otalgia disappearing at day 5 compared to day 11 for those without HOT, and otorrhea disappearing at day 6 with HOT versus day 13 without HOT.
What This Means for Canadian Patients
For Canadian patients with necrotizing otitis externa, particularly those with diabetes, adding hyperbaric oxygenotherapy to antibiotic treatment may lead to quicker symptom resolution. This could potentially reduce the duration of discomfort and improve recovery time for this severe condition.
Canadian Relevance
This study has no direct Canadian connection as it was conducted in Tunisia and does not involve Canadian researchers or patients.
Study Limitations
This was a retrospective study with a relatively small sample size of 42 patients, which limits the generalizability and strength of its conclusions.
