Minimally invasive transnasal approach for primary ectopic meningioma of the paranasal sinuses.

Endoscopic sinus surgery is a standard procedure in the treatment of various pathologies such as chronic sinusitis or some types of neoplasms. The transnasal approach to tumours of paranasal sinuses is favourable due to functional and aesthetic reasons. We report a rare case of a large primary ectopic meningioma of the paranasal sinuses in a 48-year-old woman referred to the Otolaryngology Clinic due to the incidental finding of a pathologic mass visualised on the orthopantomography picture. After diagnosis, the patient was successfully treated with radical transnasal surgery performed under endoscopic vision. In a 1-year follow-up there were no signs of tumour recurrence.
