Inverted papilloma of nose and paranasal sinuses -a clinical study.

This study includes details of twentytwo cases of inverted papilloma. It is an uncommon nasal disease. It is treated more radically than other benign conditions of the nasal cavity. The recurrence is frequent and malignant changes are also not uncommon. Histopathological study is important and requires opinion from an experienced pathologist. Rare extension into ear is also observed though the exact mechanism of spread is not understood. Long followup is essential in dealing with recurrences.
