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.
