Traumatic optic neuropathy (TON) is an important cause of severe visual loss after blunt or penetrating head and facial trauma. High-dose steroids and surgical interventions have been applied in the indirect TON. However, there is no convincing evidence that results of the treatment have any strong benefits in terms of improvement of visual acuity. Nevertheless, surgical decompression should be considered in the case of a direct bony compression to the optic nerve and a progressive visual loss in indirect TON. Neurosurgeon should be aware the surgical indication, optimal timing and relevant technique for the optic canal (OC) decompression. In this review article, we will focus on the surgical approaches to the OC and how to decompress it.

Osteoma is the most common benign tumor in the craniofacial bone. We present a case of osteoma, a rare site in a patient with palpable mass on suboccipital area. A 54-year-old woman presented with palpable mass in the right occipital area. Brain computed tomography scan indicated that the mass was starting from the outer table of the occipital bone. The mass was separated well from the cortical bone. Histopathology report presented osteoma diagnosis composed of a compact bone. After the operation, the patient was discharged without any complications and follow-up was done for 8 years without incidences of recurrence. It is very rare for osteoma to occur in the occipital bone. We reported a case of a huge osteoma of the occipital bone that grew without invasion of the inner table of the cranial bone.
