[Endoscopic sinus surgery for the treatment of inverted papilloma of nasal cavity and paranasal sinuses].

Fourteen patients suffering from inverted papilloma of the nasal cavity and sinus were operated by the intranasal endoscopic approach. The period of follow-up were 24-60 months. Only one case had recurrence after three months and was then cured by a combined treatment of external nasal approach and radiotherapy. The other 13 cases had no recurrence in the follow up period. The intranasal endoscopic surgical technique was proved a better method for treating inverted papilloma of nasal cavity and sinus even when the lesions had affected the posterior ethmoid and spenoidal sinuses. It seems that this approrch would be a new way for removing inverted papilloma completely and the major advantage of which is an incision of the face can be avoided, while the curative rate might be the same or even better than that of the external approach.
