Objective:
To assess the surgical management of patients with inverted nasal papilloma over a 14-year period.
Study Design:
Retrospective study.
Setting:
Tertiary health care center.
Results:
Fifty-three patients (38 males, 15 females) with an average age of 49.8 years were treated. Overall recurrence rate was 28% and a malignant association of 9% was shown. Recurrence rates varied from 27% in patients with more extensive disease involvement treated by lateral rhinotomy and medial maxillectomy, to 30% in patients with less extensive disease treated conservatively. Of the 5 patients with associated malignancy, 3 (6% of all patients) are likely to have undergone malignant transformation.
Conclusion:
Aggressive initial management remains the therapeutic aim in this condition.
