ABSTRACT
BACKGROUND: The purpose of this study was to define the optimal surgical strategy for sinonasal inverted papilloma in relation to the site of origin and tumor extent. METHODS: Retrospective analysis of patients affected by inverted papilloma treated by purely endoscopic or combined approaches at the Department of Otorhinolaryngology of the University of Brescia and Pavia-Varese from November 1991 to December 2007. RESULTS: Two hundred twelve patients were considered eligible for this study. An exclusive endoscopic approach was performed in 198 patients (93.4%); the remaining 14 patients (6.6%) underwent an endoscopic approach combined with an osteoplastic frontal flap. Follow-up ranged from 24 to 192 months (mean, 53.8 months). A single recurrence was observed in 12 patients (5.7%). Twenty complications (9.4%) were observed. CONCLUSION: Endoscopic surgery is the first choice in the treatment of inverted papilloma; only lesions with extensive involvement of frontal sinus and/or supraorbital cell may require a combined approach. A minimum follow-up of 5 years is recommended.

OBJECTIVES: The traditional approach to sinonasal tumors involving the skull base has been the anterior craniofacial resection. The first report by Ketcham et al (American Journal of Surgery, 1963;106:698-703) documented their experience with 17 anterior craniofacial resections for malignant tumors of the sinonasal tract. Later experience with this technique at several centers has resulted in the publication of many refinements of technique and further reduction in the morbidity and mortality associated with this procedure. In our hands, endoscopic techniques have allowed us to approach the intranasal aspect of skull base lesions without external incisions and yet still achieve an en bloc resection. The type of lesions suitable for this approach and the associated technical issues are discussed in this article. METHODS: Between 1999 and 2004, 18 patients with malignant nasoethmoid tumors underwent endoscopic nasal and anterior craniotomy resections. The average age of the patients 60.2 years, with a male-to-female distribution of 15 to 3. Mean follow-up period was 25.1 months. RESULTS: Two patients died from postoperative complications, three died from recurrent disease and two from unrelated causes. Eleven patients are free of disease with a mean survival of 19.8 months. CONCLUSIONS: Although we do not consider this approach a replacement for the traditional anterior craniofacial resection, it is an important adjunct in the skull base surgeon's armamentarium.
ABSTRACT
OBJECTIVES: To illustrate endoscopic techniques used in the treatment of esthesioneuroblastoma and to advocate this method of management followed by radiation therapy in selected cases. METHODS: A retrospective case series of 10 patients with esthesioneuroblastomas treated between 1999 and 2004 at a tertiary referral center using endonasal techniques. RESULTS: Mean age of patients at presentation was 56.2 years (median 57 years). Seven patients were female and 3 patients were male. Kadish staging at presentation was: A - 3 patients, B - 5 patients, C - 2 patients. Dulguerov stage at presentation was: T1 - 4 patients, T2 - 4 patients, T3 - 2 patients. The period of follow-up ranged from 11 months to 74 months (mean 38.1 months, median 39 months). To date no recurrence has developed in any patient. CONCLUSIONS: Our experience suggests that endoscopic surgery can be an effective method of management. Strict attention to selection criteria, careful surgical techniques, and regular follow-up are key elements for success.
