A rare location of bilateral inverted papilloma of the nose and paranasal sinuses.
Inverted papilloma is a rare benign sinonasal tumour, characterized by a potentially invasive nature. The lateral nasal wall represents the most common site of origin, whereas paranasal sinuses are involved by extension quite frequently. In contrast, primary sinus inverted papillomas have rarely been reported. Although the midfacial degloving approach has historically been the procedure of choice, recent technological advances have rendered endoscopic sinus surgery a safe procedure with equivalent success rates and low probability of papilloma recurrence. We present a rare case of bilateral inverted papilloma arising from the sphenoid septum and extending towards both the sphenoid and posterior ethmoid sinuses and the posterior section of both nasal cavities, while it slenderizes the sella turcica by compression and elevates the pituitary gland. The bilateral inverted papilloma was successfully removed with a transnasal endoscopic procedure. There is no evidence of recurrence for a follow up period of 1.5 years postoperatively. We conclude that it is a rare entity, which can be treated successfully with endoscopic sinus surgery in the hands of an experienced otorhinolaryngologist.
