Purpose: This study evaluated the significant differences in clinicopathologic features of aneurysmal bone cyst in the maxilla and mandible.
Materials and methods: A search of the literature showed 30 recorded maxillary cases, and these together with one previously unrecorded case formed the basis of the study.
Results: There were no differences in the age and sex incidence. Only two patients complained of pain, and no patient complained of tenderness. No patient gave a history of trauma. Swelling was present in virtually every patient. In seven cases, there was tooth mobility or migration of teeth. Two patients complained of paresthesia. Four patients presented with proptosis, two of whom complained of diplopia. The radiographic appearance of the aneurysmal bone cyst is suggestive but not diagnostic.
Conclusion: Although these differences do not enable the clinician to make a definitive diagnosis before biopsy, they have important implications for management.
