The treatment of trigeminal neuralgia by resecting maxillary nerve and infraorbital nerve under the endoscopy at the pterygopalatofossa through approach to the maxillary sinus / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#This paper presents a method for treating maxillary neuralgia, the second division of trigeminal nerve.@*METHOD@#One hundred and thirty six cases with 136 trigeminal neuralgia were treated from 2004 to 2011. All patients were treated with endoscopic surgery at the pterygopalatofossa through approach to the maxillary sinus for resecting maxillary nerve and infraorbital nerve.@*RESULT@#One hundred and eighteen patients were relieved after operation and no recurrence of neuralgia was occurred after 2 to 8 years of follow-up.@*CONCLUSION@#This method had the advantages of avoiding to operate craniotomy with no complications, which was performed easily with valid efficacy.

Endoscopic Resection of Nasopharyngeal Angiofibroma after Superselective Embolization / 中国微创外科杂志

Objective To explore the efficacy of endoscopic surgery for juvenile nasopharyngeal angiofibroma.MethodsDuring 27 years from March 1980 to July 2007,we performed endoscopic surgery on totally 19 patients with nasopharyngeal angiofibromas.According to Radkowski Stating,five of the patients were stage ⅠA,ten were stage ⅠB,and 4 were stage ⅡA.Before the endoscopy,superselective embolization was performed in all the cases via bilateral maxillary arteries.Results All tumors were successfully resected by endoscopy.The intraoperative blood loss was 200-600 ml.One of the stageⅡA patient developed cerebrospinal rhinorrhea during the endoscopic resection,and thus received repair of the middle turbinate by a mucosal patch immediately.In this series of patients,no massive epistaxis,intracerebral infection,or blindness occurred.Follow-up at three months after the surgery by nasoscopy showed epithelialisation of the nasal mucous membrane without residual tumor tissues.Meanwhile,otoscopy revealed normal light reflex of the eardrum,no fluid in the middle ear.Of the patients,eleven were followed up for one to five years,during which none of them had recurrent tumors confirmed by nasoscopy or CT scan.Conclusions Endoscopic resection of nasopharyngeal angiofibroma results in little trauma and few blood loss after superselective embolization.Experience and surgical skills are key points for the operation.
