Endoscopic Approach for Excision of Venous Malformation of the Orbital Apex.

INTRODUCTION: Venous malformation is a common tumor of the orbit, presenting with visual impairment and proptosis. These lesions can be excised via an external or transcranial approach, but recent advances in minimally invasive surgery have led to increased popularity of endoscopic approach.

PATIENT: The authors report a 62-year-old female presenting with diplopia and proptosis, found to have a 1.7-cm venous malformation of the orbital apex. An endoscopic trans-nasal approach was undertaken for surgical resection.

RESULTS: The tumor was successfully removed in a single specimen, without injury to the nearby orbital anatomy. The patient experienced resolution of her presenting symptoms 3 weeks after the procedure, with no adverse effects. A review of the literature demonstrates increasing reports of similar successful cases.

CONCLUSION: A minimally invasive, endoscopic resection of orbital venous malformation is possible and provides a reasonably safe and effective approach. Further large-scale studies are needed to fully explore its outcomes relative to traditional approaches.
