Endoscopic surgery of inverted papillomas under image guidance-a prospective study of 42 consecutive cases at a Danish university clinic

A treatment based on endoscopic resection with image guidance appears to offer a safe treatment modality of inverted papilloma with insignificant morbidity. Predominantly cases with nonmedial involvement of the maxillary sinus still require a supplement with the Caldwell Luc procedure. Although all the recurrences were found within 9 months postoperatively, later recurrences cannot be excluded. Long-term follow-up is recommended.
