(B) Computed tomography, axial view exhibiting pedicle (red arrow) on the internal aspect of the left angle of the mandible. (C) Surgical specimen, osteoma removed through resection of its pedicle to the left angle of the mandible. (D) Follow-up computed tomography demonstrating no lesions (the red arrow shows the point at which the osteoma was pedunculated).

Computed tomography indicated that the latter bony lesion was single, lobulated, and pedunculated on the left inner face of the mandibular angle (Fig. 1A and B). Total resection via cross-sectional cervicotomy ipsilateral to the lesion was performed through osteotomy of the lesion pedicle (Fig. 1C). She is asymptomatic and has no signs of recurrence (Fig. 1D).
