Exostosis of the optic canal in a child--a rare diagnosis in a paediatric ear, nose and throat setting: a case report.

INTRODUCTION: Optic nerve compression is an uncommon disorder leading to deterioration or complete loss of vision. CASE PRESENTATION: We describe the case of a 14-year-old Caucasian girl with a gradual deterioration of vision in her right eye. Using modern imaging techniques and endonasal endoscopic surgery, we identified the cause and removed the pathology. CONCLUSIONS: The cause of optic nerve compression was a rare exostosis in the optic canal. An endonasal endoscopic approach is the optimal choice for management of optic nerve pathologies. It is a gentle and minimally invasive surgical technique. Interdisciplinary cooperation, especially with the eye doctor and radiologist, is required in these cases.
