Although the microsurgical anatomy of the MCA in Indian population correlated with the findings in the western literature, some structural and statistical variations were noted.

Background: Giant cell tumor is a benign but locally aggressive bone neoplasm which uncommonly involves the skull. The petrous portion of the temporal bone forms a rare location for this tumor.

Although rare SSEDH requires immediate surgical decompression to avoid any permanent neurological deficit. Reconstructive surgical procedures like laminotomy are preferred in children where the incidence of spinal deformity is high following laminectomy.

Background: Osteoid osteoma is a benign bone neoplasm which is seen in the long bones of appendicular skeleton. It is rarely seen in the cranium. Skull base osteoid osteoma is extremely rare and has been anecdotally reported. Case presentation:The authors report a case of a large osteoid osteoma of the ethmoid with intraorbital and intracranial extension in a 33 year old male patient. He presented with loss of vision in the left eye. The intra-cranial extension was excised through a single burr-hole frontoorbitotomy. The ethmoid and orbital portions were approached and excised through a WeberFerguson incision and inferior orbitotomy. Radical excision of the tumor could thus be achieved through a craniofacial approach.Conclusion: Although benign and rare, skull base osteoid osteoma can present with neurological deficit due to its mass effect and involvement of vital structures. A multispeciality team approach is advisable in such cases if radical excision is to be achieved. A craniofacial approach made radical single stage excision of this multicompartmental osteoid osteoma possible with an uneventful postoperative period.
