ABSTRACT

OBJECTIVE@#To evaluate the prognosis of Draf II b surgery in treating fontal sinus inverted papilloma.@*METHOD@#A retrospective study was carried out among 15 patients diagnosed as fontal sinus inverted papilloma, which had underwent endoscopic Draf II b surgery. The clinical success rate and surgical success rate were calculated by survival analysis.@*RESULT@#In all patients, there were 1 (6.67%) recurrence,1 (6.67%) stenosis, 4 (26.67)% complete closure, and 1 (6.67%) mucocele cyst. The 3-year clinical success rate was 93.3%, and the 3-year surgical success rate was 65.0%.@*CONCLUSION@#Draf II b surgery is feasible when the frontal sinus inverted papilloma is involved in the area of the pupil center line, and the frontal neo-ostium stenosis or complete closure is a common complication after surgery. Thus a close follow-up is recommended during the first year after the surgery. Further study is necessary to find a better way to reduce the complication rate.
