title: Endoscopic sinus surgery for sinonasal haemangiopericytomas.
abstract: Haemangiopericytomas are rare peri-vascular tumours with variable malignant potential. The nasal cavity and the paranasal sinuses are most often involved in the head and neck. Five cases of haemangiopericytomas treated by a strict endonasal endoscopic approach are presented. Bleeding and nasal obstruction are the most frequent symptoms. Computed tomography (CT) scan and magnetic resonance imaging (MRI) allowed pre-operative assessment. Angiography with embolization was needed in two of the five cases. None of our patients presented with malignant histology. Our five cases were operated on, and a total tumour excision was performed through the endoscopic endonasal approach. We had one recurrence with a mean follow-up of 4.5 years. We suggest that when the tumour is purely intranasal or strictly located in the ethmoid or sphenoid sinus, it can be removed via an endonasal approach under endoscopic guidance in experienced hands.
