A sizeable aneurysmal bone cyst of the mandibular ramus on 15-year-old patient. Intraoral approach

Abstract

Aneurysmal bone cysts (ABCs) are benign, non-neoplastic bone lesions, which contain blood and demonstrate a destructive pattern. They rarely occur in the head and neck region, with the mandible being the most common site of craniofacial origin. They develop in the second decade of life and their etiology is obscure. ABCs can sometimes demonstrate distinct radiological features and imaging is also necessary for preoperative planning. Surgery is the mainstay of treatment. The ABC should be excised in toto and usually osteotomies and primary reconstruction are necessary. We present a case of sizeable ABC of the mandibular ramus that was excised intraorally, without the need of combined approaches or reconstruction.
