Abstract:
Osteomas are benign tumors composed of mature, compact, or cancellous bone that commonly arise in the sinuses and exhibit slow and asymptomatic growth. Surgical resection may be performed using intraoral or extraoral approaches when functional or morphological deficits are present. A 63-year-old female presented with an osteoma in the subcondylar region, which had doubled in size 9 years after the initial diagnosis. Considering the potential risk of functional impairment, the osteoma was excised using the high perimandibular approach. Two years postsurgery, the patient remained asymptomatic, with no functional or morphological deficits or recurrence of the disease. This case report describes the successful use of the high perimandibular approach for managing an osteoma in the subcondylar region and highlights its clinical versatility.
