Endoscopic Approach for Resection of Frontal Forehead Osteoma: Technical Case Report Instruction

Forehead osteomas are benign bone tumors. They are frequently associated with exophytic growth in the outer table of the skull, causing cosmetic disfigurement of the face.^1-9 The objective of this study was to present the efficacy and feasibility of the endoscopic treatment of forehead osteomas by presenting a case report with details of the surgical technique. A 40-year-old female patient presented with aesthetic complains of a progressing bulge in the forehead. A computed tomography scan with 3-dimensional reconstruction showed bone lesions on the right side of the forehead. The patient underwent surgery under general anesthesia with no noticeable incision, which was planned 2 cm behind the hairline in the midline because the osteoma was close to the midline plane on the forehead (Video 1). A retractor coupled with a 4-mm channel for endoscopy and a 30-degree optic was used to dissect, elevate the pericranium, and locate the 2 bone lesions in the forehead. The lesions were removed using a chisel, endoscopic facelifting raspatory, and a 3-mm burr drill. The tumors were resected completely, resulting in good cosmetic outcomes. The endoscopic approach for treating forehead osteomas is less invasive and facilitates complete removal of tumors, which results in good cosmetic outcomes. Neurosurgeons should consider and add this feasible approach to enhance their surgical armamentarium.
