Navigating the unusual: A case of osteoid osteoma on the external skull table

Osteomas are benign, slow-growing tumours composed of mature bone, typically found in the paranasal sinuses and skull. Surgical excision is the preferred treatment, especially when the osteoma causes functional impairment, neurological symptoms or cosmetic concerns. This case report describes the successful removal of an osteoma from the external table of the skull using a chisel and mallet technique. The patient had a firm mass over the frontal region, which was confirmed as a well-circumscribed osteoma via radiographic imaging. The lesion was excised while preserving the surrounding tissues. Postoperatively, the patient had an uncomplicated recovery, with no recurrence at the 6-month follow-up. This case demonstrates the effectiveness and safety of using conventional tools for osteoma excision when the tumour is accessible, with minimal complication risk.
