Abstract

Objective:To carry out a systematic review of available data of aneurysmal bone cyst (ABC) of the jaws.

Methods: The methodology followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020. A systematic search until in four databases and grey literature was conducted. As eligibility criteria, case reports and case series describing the clinicopathological and management of ABC were included. The quality assessment of the studies was performedby the Joanna Briggs Institute's (JBI) tool.

Results: A total of 190 studies reporting 257 cases were evaluated. ABCs affected females slightly more (53.9%), with a mean age of 19.7 years. In 64.4% of cases, no history of trauma was reported. Most lesions were symptomatic (53.2%) and located in the posterior mandible (77.8%). Clinically, they appeared as firm swellings or nodules (95.8%). Multilocular (67.9%) radiolucency (87.4%) was the predominant radiographic feature. Marginal or segmental resection was the most common treatment (34.2%), and 86.4% of patients had no recurrence. While case reports adhered well to JBI guidelines, case series often lacked demographic detail and participant selection criteria

Conclusion: ABCs of the jaws predominantly affect young individuals without a marked gender predilection and are most frequently located in the posterior mandible.
