Application of fenestration for treatment of large jaw cystic lesions

Abstract

Objective To explore the effect of fenestration for large jaw cystic lesions. Methods Eighteen cases of large odontogenic cyst of maxillofacial areas in our department in 2013-2017 years were treated with fenestration, and the changes of cysts in 3 years after the operation were observed. Results After 1-3 years of follow-up, the cystic cavity disappeared in 15 cases, 2 cases recurred and 1 case was not effective, which was treated by traditional operation. In the cases of fenestration, the bone growth in the lesion area recovered well, and the clinical symptoms were eliminated. Conclusions Fenestration for large jaw bone cystic lesions is feasible. The pulp of the affected teeth was preserved as far as possible. After the bone growth around the capsule, the root canal therapy was considered one year after the fenestration according to the dental pulp test.
