Purpose: This study aimed to assess the prevalence, demographics, clinicohistopathological features and treatment outcomes of maxillofacial aneurysmal bone cysts (ABCs) in Isfahan.
Materials and method: A unicenter retrospective study of patient charts dated from 1987-2013 (26 years) was undertaken to assess maxillofacial ABCs. Variables such as age, gender, location (maxilla, mandible, anterior or posterior segments), histological type (solid, mixed, vascular), signs, symptoms, radiographic features ,treatment modalities and outcomes of this lesion were evaluated by the authors. The data was analyzed using SPSS 20 software (p<0.05).
Result: 16 patients were diagnosed and treated in our study, which included 6 (37.5%) males and 10 (62.5%) females. There was a significant female predilection (p<0.05). The mean age of occurrence was16.2 ± 7.9 years ranging from 6 to 28 years.The prevalence was not significantly higher in any decade of life. The rate of affliction was 0.6 case per year. ABC was significantly more common in the mandible (p<0.05) and the posterior areas (p<0.05). The most common histopathological type was the mixed type (p<0.05).Bony hard Swelling was the most common clinical finding (p<0.05) and all cases were radiolucent. All cases were treated with excision and curettage. Two patients (12.5%) showed recurrence during the follow-up period (1-26 years).There was no relationship between recurrence and other parameters.
Conclusion: ABCs of the jaws are rare lesions with variable presentation and often respond well to excision and curettage. Apparently it seems that there is no need to do more aggressive surgery because recurrence is low.
