ANEURYSMAL BONE CYST OF THE JAWS: A SYSTEMATIC REVIEW

Abstract

<h3>Objectives</h3> To integrate the literature data on aneurysmal bone cyst (ABC) of the jaws into a systematic review of the clinicopathologic features, treatment, and recurrence. <h3>Study design</h3> This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement (PRISMA). PubMed, Web of Science, Scopus, and Embase electronic databases were searched. Case reports and case series reporting ABC of the jaws with predefined eligibility criteria were included. <h3>Results</h3> Out of 1,393 references, 151 articles (173 cases) met eligibility criteria. Female individuals (n = 88, 50.9%) with a mean age of 19.2 years (±12.35950 SD) were more affected. Regarding the anatomical location, the mandible (80.9%) was more affected. Clinically, most of the lesions presented as an extraoral swelling (n = 102, 50.2%), followed by intraoral swelling (n = 57, 28.1%). ABCs commonly presented as multilocular (n = 49, 20%) radiolucent (n = 93, 38%) lesions and 23.1% of the cases occurred in association with another lesion. Treatment of choice was mostly conservative (56.1%), presenting a low recurrence rate (n = 18, 10.4%). <h3>Conclusions</h3> Most of the ABCs included in this study occurred in young individuals presenting a low prevalence of recurrences. These results can help professionals to recognize the main clinicopathologic manifestations of ABCs.
