Solitary and Aneurysmal Bone Cysts of Jaws: a Clinico-Pathological Investigation
Objectives: Solitary bone cysts (SBC) and aneurysmal bone cysts (ABC) of the jaws are non-epithelial lined cysts of unclear aetiology. There is limited literature on the presentation and management of these rare cysts in the jaws. The aim of this study was thus to describe the clinico-pathological features of these cysts as well as their management and recurrence patterns.
Methods: A retrospective cross-sectional analytical study was conducted for a period of 40 years. The data recorded included demographic details, clinical signs and symptoms as well as history of trauma/ orthodontic treatment. Radiographic features assessed included location, density, locularity, size and effects on adjacent structures. Surgical approaches were analysed along with follow-up records.
Results: A total of 32 SBCs and 5 ABCs were included with mean age of 21 years for SBC and 22 years for ABC. The majority of SBCs occurred in males (58.62%) while four ABCs presented in females (80.0%). Only 2 cases of SBCs were symptomatic (6.2%) while no history of trauma was noted for both lesions. Most SBCs (96.8%) and all ABCs presented in the mandible. Radiographically, the majority of SBCs (75%) appeared as radiolucent while 2 lesions were associated with cement-osseous dysplasia (6.2%). All ABCs were of mixed density. Most SBCs were managed by surgical exploration (62.5%) and curettage (37.5%) with no recurrences. All ABCs were also managed with surgical exploration with the majority of lesions demonstrating dark venous blood.
Conclusions: Both lesions presented in younger individuals in the mandible with no history of trauma and were mostly asymptomatic. Most lesions appeared as lucent or mixed in density on radiographs. ABC and SBC should form part of differential diagnosis of well-defined radiolucencies not associated with dentition in the jaws. These lesions should be surgically explored/ curated to confirm the diagnosis and this also forms part of their management.
