Treatment options of T1 glottic carcinoma / 临床耳鼻咽喉头颈外科杂志

T1 glottic carcinoma is part of early laryngeal carcinoma which involves the vocal cords, including anterior commissure or posterior commissure. We analyzed the treatment options of T1 glottic carcinoma by reviewing the related literatures about T1 glottic carcinoma treated by conservative surgery (open surgery and laser microsurgery), radiotherapy, robot surgery, photodynamic treatment.

The application septonasal bidirectional mucoperiosteal flap in treatment of refractory choanal atresia in adults / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the effects of septonasal bidirectional mucoperiosteal flap in the treatment of refractory choanal atresia in adults.@*METHOD@#Analysis of 9 cases for choanal atresia was conducted. Two cases were of congenital origin and 7 cases of acquired origin, which was a complication of radiotherapy for nasopharyngeal carcinoma. The patients received transnasal endoscopic surgery using the septonasal bidirectional mucoperiosteal flap, without positioning the postoperative expansion tube. After the operation, the changes of symptoms were observed and the recurrent rate of restenosis or atresia was investigated in the follow-up time.@*RESULT@#The symptoms of nasal obstruction and mouth breathing improved significantly in the 9 patients. At an average follow-up time of 19.3 months, the new forming posterior nare remained patent. The mucoperiosteal flap had no shift or necrosis. No restenosis or atresia happened. Nasal adhesion occurred in two patients. Granulation tissue hyperplasia was found in 1 patient, who underwent endoscopic revision without recurrence.@*CONCLUSION@#The application of mucoperiosteal flap in transnasal endoscopic surgery for the choanal atresia can reduce the incidence of restenosis or atresia. Postoperative expansion tube is not mandatory.
