RESUMO
OBJECTIVE To review the clinical and image features of the patients with grade III-IV tracheal stenosis, and the surgical outcomes of tracheal sleeve resection and end-to-end anastomosis in the treatment of severe tracheal stenosis. METHODS Between July 2008 and July 2016, 20 patients with grade III-IV tracheal stenosis underwent tracheal sleeve resection and end-to-end anastomosis. RESULTS Postoperative decannulation was achieved in 17 patients(85.0％), and restenosis developed in 3 patients(15.0％). Postoperative complications were: 1 case wound infection, 4 cases subcutaneous emphysema, 3 cases temporary unilateral vocal fold palsy. Suture dehiscence, irreversible injury of the recurrent laryngeal nerves was not observed in our patients. No perioperative mortality occurred. CONCLUSION The tracheal sleeve resection and end-to-end anastomosis represent a viable treatment for severe tracheal stenosis. Long segment stenosis should not be considered as a contraindication. This surgical method should be considered cautiously in patients with diabetes.
RESUMO
OBJECTIVE@#To investigate the clinical characteristics of nasopharyngeal teratomas (NPT), improve the diagnosis and treatment of the disease.@*METHOD@#We reported a 14 years old girl with NPT, and reviewed the literatures.@*RESULT@#NPT was transorally expected under nasal endoscope, no recurrence was found over a 5 year follow-up.@*CONCLUSION@#NPT is rare,the diagnosis of the disease relies on clinical manifestations, imaging and pathological examination. Transoral endoscopic surgery is an effective method of treatment.
