title: Endoscopic, endonasal management of sinonasal haemangiopericytoma: 12-year experience.
abstract: OBJECTIVE
  To report our experience with endoscopic, endonasal management of sinonasal haemangiopericytoma.
  
  
  METHODS
  Retrospective review of the medical records of 10 patients undergoing endoscopic, endonasal surgery for sinonasal haemangiopericytoma of the nose and paranasal sinuses, between 1997 and 2008.
  
  
  RESULTS
  Five men and five women were included. Their mean age at surgery was 59 years. All patients underwent endoscopic, endonasal resection of their tumour. Major post-operative complications were encountered in only one patient (stroke). Local recurrence was diagnosed in only one patient (10 per cent), who subsequently underwent a combined resection (endoscopic and external) with orbital exenteration.
  
  
  CONCLUSIONS
  Sinonasal haemangiopericytomas are rare tumours that are usually benign. The mainstay of treatment is wide surgical excision with free resection margins. Nowadays, the great majority of patients can be treated using a purely endoscopic, endonasal approach.
