Cystic lesions of the jaws in edentulous patients: analysis of 27 cases.

In this retrospective study we reviewed the distribution, characteristics, and treatment of 27 cystic jaw lesions in edentulous patients, and compared these with 242 cysts in dentate patients. The mean age was 60 years (range 46-74), and the male:female ratio 4.4:1. The maxilla was more affected than the mandible, with radicular/residual cysts being the most common. Patients were treated by marsupialisation, enucleation, or enucleation with bone grafting. Edentulous men were at higher risk than women of developing cystic lesions in the maxilla. Patients who are edentulous alert us to the possibility that their general health may be compromised, and this should be kept in mind when planning treatment.
