[The management of sinonasal inverted papilloma by endoscopic surgery: an analysis of 54 cases].

OBJECTIVE

The study is to evaluate our results of patients with sinonasal inverted papilloma (SIP) undergoing endoscopic sinus surgery and to investigate the recurrence relative factors of SIP.

METHOD

A retrospec- tive analysis was performed of medical records for 54 cases SIP treated with endoscopic resection. Compared to pre operation imaging evaluation and intraoperative observation, efficacy assessments included endoscopy during follow-up after operation and combined with CT examination results.

RESULT

The incidence of 54 cases with ethmoid sinus, part of the lateral wall of the nasal cavity was higher. The recurrence rate was higher in the cases invaded front and/or inferior wall of maxillary sinus, frontal recess. There was no case with middle turbinate. Canceration with the same time accounted for 1.85%.

CONCLUSION

Misdiagnosis as polyps, the lesion sites of tumour, involving the frontal recess, front and inferior wall of maxillary sinus are the risk factors of recurrence. The preoperative accurate judgment of the primary tumor site and surgical resection completly are the most effective means of preventing recurrence. Postoperative endoscopy examination combined with CT examination is an effective means for the evaluation of recurrence.
