Highlights

•	ABCs in the head and neck region are uncommon and occur usually in the second decade of life.
•	They most commonly affect the mandible, the sinuses, and the cranium.
•	Given the low recurrence rates surgical excision should be performed with the least morbidity in mind.
•	The surgeon should be prepared to convert an intraoral procedure and/or be able to perform appropriate primary reconstruction.

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.
