Denker's approach was used in the management of 78 patients presenting with
an inverted papilloma of the nasal sinus complex between the years 1986 an
d 1993 at the University Teaching Hospital in Rotterdam. The recurrence rat
e was 9% with a mean follow-up after surgery of 56 months. There was minima
l morbidity and no mortality associated with the procedure. Three patients
had a squamous cell carcinoma associated with the inverted papilloma. The r
esults of our study indicate that Denker's approach has a similar or lower
recurrence rate than an open external approach to papilloma and is a safe p
rocedure with minimal morbidity.
