［］ Objective: To explore the application value and therapeutic effect of one-stage implantation of absorbable collagen membrane in the operation of anterior combined glottic carcinoma under support laryngoscope. Methods: 19 patients with anterior combined glottic carcinoma underwent laryngeal tumor resection under general anesthesia supported laryngoscope. At the same time, they placed and trimmed the appropriate size absorbable collagen membrane and fixed it with cricothyroid membrane. After 1 week, the external laryngeal fixation suture was removed. All patients were followed up for 6 months to 5 years. The content of the follow-up included: vocal cord wound recovery, anterior joint morphology, and pronunciation function indicators. Results: 1. During the postoperative follow-up, except for 1 patient who found residual tumor recurrence during the 1 month postoperative reexamination, 3 patients had vocal cord adhesions, and the remaining 15 patients had no dyspnea and the vocal cords had a good triangle shape before the joint; 2 In the postoperative pain score, 17 cases (89.5%) had mild pain, 2 cases (10.5%) had moderate pain, and none of them had severe pain. 3. Voice function assessment and subjective acoustic parameter VHI surgery were performed after the mucosal function was stable for half a year after the operation. Before and after (19.37±5.73 vs 60.63±12.93), the difference was statistically significant (p<0.001); the objective acoustic parameters before and after MPT surgery (10.07±1.47vs14.40±1.48), the difference was statistically significant (p<0.001); Before and after DSI surgery (-1.52±4.20vs0.97±2.12), the difference was statistically significant (p<0.001). Conclusion: The first-stage implantation of absorbable collagen membrane can prevent bilateral vocal cord adhesions after resection of early glottic laryngeal carcinoma, and the patients have mild postoperative pain, which can promote the recovery of postoperative laryngeal function without adverse reactions.
