Revision endoscopic sinus surgery on chronic sinusitis and polyps

Objective:To study the indications,surgical landmarks,surgical significance,complications and operative avoidance of revision endoscopic sinus surgery on chronic sinusitis and polyps.Method:We performed revision endoscopic sinus surgery on 112 cases of chronic sinusitis and polyps under controlled hypotension anaesthesia by using the Messerklinger technique and Stryker debrider.Result:89 cases were successful and 17 unresolved,6 failed,all the complications consist of cerebrospinal fistula in one, orbital hematoma in four,increased tearing in three and profuse bleeding in 6 patients.Conclusion:Revision endoscopic sinus surgery was advised in case of sinuous obstruction caused by uncontrolled lesions under postoperative care,which can do good for adhesion and obstruction except nasal polyposis.The reminant of the middle turbinate and the upper arch of choana were helpful operative landmarks.Preoperative CT scan decrease the complications.
