Abstract
- Objective: To study the clinical effect of heterogeneity (cattle) acellular dunal matrix in repairing mucosa defect in laryngeal surgery.<br />Methods: Eighteen cancer patients with mucosa defect in central vocal area accepted treatment with heterogeneity acellular dunal matrix after surgery. There were two methods to repair mucosa defect. One was simple use of acellular dunal matrix, the second was combined use of acellular dunal matrix and muscle lamella or muscle and tendon film lamella. 18 cases had cancer in central vocal area: T2N0M0 (8), T3N1M0 (5), T3N2M0 (4), T4N2M0 (1). All were squamous cell carcinoma. Ten cancer patients accepted radiation after surgery. The radiotherapy volume was 60-80 Gy. After the operation, the patients were checked by fibrolaryngoscope four or five times after half a year, observing the dynamic development.<br />Results: All 18 patients were healed, rechecked by endoscope after 0.5-6 months, heterogeneity acellular dunal matrix mingled with mucosa within 30-60 d, no allergy and irritation were found. The laryngeal function, including breathing, pronouncing and swallowing, was recovered. The survival rate (1 year) was 100%, and 10 patients survived after 2 years. After radiotherapy, the process of recovery was not affected.<br />Conclusions: Heterogeneity acellular dunal matrix can be easily obtained and it is a new method to repair mucosa defect. The operative procedure is easy to perform and worthwhile to use clinically.
