Abstract

Objective: To demonstrate the potentials and limitations of three different endoscopic procedures employed for treatment of inverted papilloma (IP) of the sinonasal tract.

Study Design: Retrospective analysis of a cohort of patients treated at two University hospitals.

Methods: From January 1992 to June 2000, 47 patients with IP underwent endoscopic resection. Preoperative workup included multiple biopsies of the lesion and imaging evaluation by computed tomography or magnetic resonance imaging. Massive skull base erosion, intradural or intraorbital extension, extensive involvement of the frontal sinus, abundant scar tissue caused by previous surgery, or the concomitant presence of squamous cell carcinoma were considered absolute contraindications for a purely endoscopic approach. Three types of resection were used: ethmoidectomy with wide antrostomy and sphenoidotomy (type 1) for IPs confined to the middle meatus, medial maxillectomy with ethmoidectomy and sphenoidotomy (type 2) for IPs partially invading the maxillary sinus, and a Sturmann-Canfield operation (type 3) for IPs involving the mucosa of the alveolar recess or of the anterolateral corner of the maxillary sinus. All patients were followed by periodic endoscopic evaluations.

Results: Type 1, 2, and 3 resections were performed in 26, 15, and 6 patients, respectively. No recurrences were observed after a mean follow-up of 55 (range 30–132) months. One patient, who underwent a type 2 resection, developed a stenosis of the lacrimal pathways requiring endoscopic dacryocystorhinostomy.

Conclusions: Our experience confirms that endoscopic surgery is an effective and safe method of treatment for most IPs. The availability of different endoscopic techniques allows the entity of the dissection to be modulated in relation to the extent of disease. Strict application of selection criteria, meticulous use of subperiosteal dissection in the involved areas, and regular follow-up evaluation are key elements for success.
