What Researchers Did
Researchers retrospectively examined six patients with severe laryngeal chondroradionecrosis to evaluate diagnostic methods and treatment outcomes.
What They Found
CT scans identified chondroradionecrosis in the anterior larynx in three patients and posterior larynx in three patients, with one false-positive PET result. Patients underwent a mean of 36+/-6 hyperbaric oxygen (HBO) dives. Five out of six patients (83%) showed CRN improvement after early debridement and HBO, with no tumour recurrence over a mean 24-month follow-up, though one patient required total laryngectomy.
What This Means for Canadian Patients
Canadian patients suffering from laryngeal chondroradionecrosis following radiation therapy might benefit from early diagnosis using endoscopy and imaging, coupled with debridement and hyperbaric oxygen therapy. This approach could potentially help save the functional larynx and avoid more invasive procedures like total laryngectomy.
Canadian Relevance
This study covers chondroradionecrosis, which is a Health Canada-recognised indication for hyperbaric oxygen therapy.
Study Limitations
The primary limitation of this study is its very small sample size of only six patients, which restricts the generalizability of the findings.
