Abstract
Objective:To retrospectively analyze the clinical effect of biomaterial combined with silicone keel technology in the prevention and treatment of vocal folds adhesion. Methods:The basic data, perioperative conditions and prognosis of 21 cases of vocal folds adhesion treated by biofilm-silicone keel complex were retrospectively analyzed in Huashan Hospital Fudan University. Results:A total of 21 patients were enrolled in this study（19 males（90.5%）, 2 females（9.5%）. Among these patients, 18 cases of early glottic laryngeal carcinoma（T1b）, 1 case of bilateral vocal folds leukoplecta and 2 cases of postoperative vocal folds adhesion. No accidental rupture of the silicone keel occurred during perioperative period, and the silicone keel was removed in 22.4±2.6 days. All patients were reviewed after removing the silicone keel, the overall effective rate was 90.5%（19/21）. Postoperative complications occurred in 5 patients（1 laryngeal infection, 4 granulation tissue hyperplasia）, all of whom were cured after conservative treatment. Conclusion:This study explored the feasibility of biomaterial in the treatment of vocal folds adhesion. The biomaterial-silicone keel complex technology is simple to operate and has effect on the prevention of vocal folds adhesions, which is worth of clinical promotion.
