Revision endoscopic sinus surgery and combined therapy for recurrent sinusitis / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the efficacy of revision endoscopic sinus surgery and combined therapy on recurrent sinusitis and polyps.@*METHOD@#Revision endoscopic sinus surgery was performed in 72 patients, of which endoscopic nasal lateral wall dissection was used in 3 cases, the endoscopic frontal sinus surgery (Draf I-II) was used in 16 cases, and all patients received combined therapy including peri-operation conservative management and nasal endoscopy examination during the follow-up period.@*RESULT@#All patients were followed up for more than one year. Of 72 patients, 52 patients were successfully cured, 10 patients showed improvement, but there was no change in other 13 patients. The total efficacy rate was 91.67% (66/72). No serious complication occurred.@*CONCLUSION@#The treatment efficacy can be greatly improved by enough preoperative preparation, fine operation, combined pre-operation conservative therapy and postoperative follow-up.
