Abstract:Objective: To review the clinical features of the patients with laryngeal stenosis after laryngeal cancer surgery, and the surgical outcomes of the repair of anterior cervical rotation portal myocutaneous flap in the treatment of laryngeal stenosis.Methods: Between January 2018 and October 2021,39 patients with laryngeal stenosis after laryngeal cancer were retrospectively analyzed. 19 patients underwent the anterior cervical rotation portal myocutaneous flap repair.20 patients underwent CO2 laser surgery under microscopic support laryngoscope.All patients were followed up for 1 month to 36 months after operation.The treatment conditions and extubation time of the patients were recorded. Results: Among the 39 patients with laryngeal stenosis, 19 patients who underwent the repair of anterior cervical rotation portal myocutaneous flap had a successful extubation rate of 78.95% after one operation, which was higher than that of those who underwent CO2 laser surgery under microscopic support laryngoscope(50.00%). In the treatment of patients with laryngeal stenosis,the anterior cervical stenosis myocutaneous flap repair has a higher rate of postoperative extubation and a lower incidence of restenosis than CO2 laser under microscopic support laryngoscopy. Conclusion: The repair of anterior cervical rotation portal myocutaneous flap is an effective treatment for the patients with laryngeal stenosis after laryngeal cancer surgery.
