THE CASE OF INVERTED PAPILLOMA INVOLVING BASE OF SKULL

Skull base inverted papilloma (IP) is a rare case of Sino nasal tumor. The complex anatomy of the facial and bones of the skull as well as clinical presentations of the malignancy makes diagnosis of the condition difficult. However, the tumor has high potency for recurring in addition to malignant degeneration. In a case study of a 59-year old male, medical investigations involving nasal endoscopy examination, magnetic resonance imaging (MRI) and computed tomography (CT) scans are important in identifying the TUMORS of skull base inverted papilloma. Certainly, signs and symptoms of skull base IP are nasal obstructions, headache, low vision, epistasis, loss of smell and sinusitis. The modern medical imaging has initiated the development of efficiency and safety choice of surgical approaches in the treatment of skull base IP. Evidently, NASAL endoscopic surgery involving resection of the Sino nasal tumors have been considered gold standards in the treatment of skull base IP. The approach is less invasive as it does not involve incision of the skull and facial bones. Besides, endoscopy techniques are associated with less pain, reduced tumor manipulation, fewer rates of recurrence and improved cosmetic outcomes. However, the effectiveness of the technique is ascertained in patient follow-ups between 1 and 11 months. Key Words: inverted papilloma, sinus surgery, skull base, endoscopy, sinonasal tumors
