The application of mitomycin C in treatment of airway scarring stenosis / 临床耳鼻咽喉头颈外科杂志

ABSTRACT

OBJECTIVE@#To explore the feasibility and efficacy of mitomycin C(MMC) in the treatment of airway scarring stenosis.@*METHOD@#The clinical materials of 11 patients with airway stenosis treated with MMC from 2008 to 2012 were analyzed retrospectively,including atresiaofnasopharynx/choanal atresia (2 cases), pharyngostenosis (1 case), and laryngotracheal stenosis (8 cases). All were treated with endoscopic surgery under general anesthesia. Patients received topical application of MMC (0.4 mg/ml) to the lesion for 5 minutes after the scar tissue removed and repeated five times.@*RESULT@#No patients occurred restenosis in 2 months' follow-up postoperative. Two patients with atresiaofnasopharynx/choanal atresia achieved satisfactory ventilation outcome, 8 patients with laryngotracheal stenosis decannulated successfully, 1 patients with pharyngostenosis achieved near normal deglutition.@*CONCLUSION@#MMC in endoscopic airway surgery is safe and effective in the treatment of airway stenosis and offers a high success rate for patients with grade 1-2 stenosis. It should be used as a first method in the treatment of airway stenosis.
