Abstract: Sinonasal inverted papilloma—benign, but locally aggressive tending to recur, and often associated with malignancy—have necessitated a radical external approach, including lateral rhinotomy. This is changing, however, to initial endoscopic sinus surgery (ESS). Using navigation with computed tomography (CT) reduces the surgeon’s stress and aids in safe curative resection. All of the 13 cases of sinonasal inverted papillomas we treated between September 2004 and October 2010 were initially treated using ESS, and navigation was introduced in October 2006. Of these 13, 9 were classified as Krouse’s staging T2, 3 as T3, and 1 as T4. Recurrence was seen in 4 of the 9 whose tumors were preoperatively classified as T2, often near important structures, such as the medial orbital wall, and where ESS is difficult, such as the orifice and anterior maxillary sinus wall. Tumors recurrent in the orifice and anterior wall were resected using ESS and the Caldwell-Luc procedure—a dual approach that may be the first choice in cases involving the anterior maxillary sinus wall. One subject diagnosed with synchronous malignancy underwent radical resection by lateral rhinotomy and adjuvant chemoradiotherapy.
