Objective: Sinonasal inverted papilloma is a rare benign tumor with a high recurrence rate and potential malignant transformation. The purpose of this study was to analyze the clinical and radiological aspects and to identify the suitable surgical approaches to be used in developing countries. Methodology: In 3 years, 7 cases have been analyzed in a retrospective study. Patients presented with unilateral nasal obstruction and epitasis, a whitish unilateral polypoid mass, sinonasal opacity with osteolysis on CT scan or on sinus X-ray. Using these data we adopted the Krouse staging which classifies the disease in four stages and accordingly the appropriate surgical approach was used. The diagnosis was confirmed by histological examination of the biopsied specimen. Results: Average age 48.28 years, predominant sex male. Symptom: unilateral nasal obstruction 5, bilateral nasal obstruction 1, epistaxis 5. The average time-delay before consultation was 73 months. The combined endonasal endoscopic and vestibular was the most commonly used approach (4 cases). The results were satisfying. After a minimal follow up of 2 years, one case of recurrence was detected after 4 years. Conclusion: CT scan is an essential tool for the diagnosis and detecting the extension of sinonasal inverted papillomas. Better results were obtained with a surgical approach that combined a vestibular approach and an endonasal endoscopic approach in our region.
