Eighty-nine patients with sinonasal inverted papilloma presenting between 1975 and 1995 were reviewed with the aims of studying predictors of tumour behaviour and correlating outcome with p53 expression. Correlation of clinical, radiological features and p53 status was made using X2 and multiple logistic regression analysis with recurrence and malignant degeneration as the main outcome measures. Two patients had synchronous malignancy but no malignant degeneration was seen. There was no significant difference in recurrence between minor intranasal procedures and more extensive surgery for the first event. Younger patients were more likely to recur. (P = 0.0493, odds ratio 0.43). Those who smoked showed a trend towards multiple recurrence. p53 was expressed in 41% but did not predict recurrence. Morbidity was related to the extent of surgery. Inverted papilloma presenting to a non-tertiary centre is more benign than previously reported. Initial management by less extensive endoscopic surgery may reduce morbidity.
