Summary
Laryngeal radionecrosis, a rare complication of radiotherapy, presents diagnostic challenges. Surgical intervention, often total laryngectomy, is crucial for this life-threatening condition, even with negative biopsies.
Area of Science:
- Otolaryngology
- Radiation Oncology
- Surgical Pathology
Context:
- Laryngeal radionecrosis is an infrequent but serious late complication following radiotherapy.
- Distinguishing radionecrosis from recurrent laryngeal cancer poses significant diagnostic hurdles.
- This study reviews six cases of surgically treated Chandler grade IV laryngeal radionecrosis over 15 years.
Purpose:
- To highlight the diagnostic difficulties in differentiating laryngeal radionecrosis from recurrent cancer.
- To present the authors' experience in managing severe laryngeal radionecrosis.
- To discuss treatment strategies for this life-threatening complication.
Summary:
- Complications occurred between 1 and 45 years post-radiotherapy.
- All cases showed negative results on repeated biopsies.
- Intensive pharmacological and surgical treatment is required for laryngeal radionecrosis.
Impact:
- Total laryngectomy is the preferred surgical option for non-functioning larynges, even with negative biopsies.
- Artery flaps combined with total laryngectomy may be indicated to mitigate postoperative complications like skin necrosis and pharyngeal fistula.
