Background and Objectives: Frontal bone osteomas are benign tumors characterized by the abnormal proliferation of bone. Though typically asymptomatic, these masses often produce visible forehead deformity and may cause localized discomfort. Endoscopic resection has emerged as an optimal technique for appropriately selected frontal osteomas because it enables complete excision while minimizing visible scarring and risk of neurovascular injury. This case series reviews the senior author's patient outcomes and complications using a scalp-based, endoscopic-assisted surgical approach for frontal bone osteoma excision. Materials and Methods: A review was conducted of all patients (n = 22) who underwent endoscopic-assisted frontal bone osteoma excision performed by a single surgeon between February 2019 and December 2025. All procedures involved endoscopic visualization through remote scalp incisions, osteoma excision, and frontal bone contouring. Patient demographics, presenting symptoms, CT imaging findings, operative details, histopathology results, and postoperative outcomes were recorded. Results: Twenty-two patients underwent endoscopic-assisted excision of frontal bone osteomas performed by the senior author (NT). The primary concern prompting surgical intervention was aesthetic deformity, with localized pain reported in some cases. For all patients, CT imaging was obtained preoperatively to evaluate lesion size and anatomical relationships to nearby facial structures. Histopathology confirmed cortical bone consistent with osteoma in all cases. Postoperative swelling and ecchymosis were common in the first week but resolved spontaneously. No contour irregularities, fluid collections, residual bone, or sensory deficits were observed. Some alopecia was noted in the first three patients, prompting the senior author to modify the technique. All patients healed with small, flat, well-concealed scars adjacent to the hairline. Conclusions: This single-surgeon experience demonstrates that endoscopic-assisted excision of frontal bone osteomas is a safe and effective technique that permits complete excision with excellent aesthetic outcomes and minimal morbidity. The operative framework presented in this study, including surgical planning, technique steps, and postoperative management, supports endoscopic resection as an ideal alternative to traditional direct approaches for frontal bone osteomas.
