Clinical analysis of biomaterial-silicone keel complex in the vocal folds adhesion treatment
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 condi-tions 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).Postopera-tive 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.
