Precise locating and cutting of the bone lid with a digital template during the treatment of large mandibular cysts: A case series study

The aim of the study was to investigate the efficacy and safety of a digital template in the bone lid technique during enucleation of large mandibular cysts. Six patients were enrolled in this study. Patients' preoperative CT data were collected to design and produce the digital templates. The bone lids were located and cut under the guidance of the digital templates, and then replanted and fixed following cyst enucleation. Postoperative clinical symptoms were observed and recorded from postoperative days 1-7. The follow-up visits were set at 3, 6, and 12 months. The cystic lesions were exactly and fully exposed without the need for secondary bone removal. The contours of the mandibles recovered well, with excellent sealing of the defects. Apart from one case with postoperative infection and one case with 2-month numbness of the lower lip, no other complications occurred. Six months after the surgery, patients' appearance and function were well-restored. A digital template in the bone lid technique during enucleation of large mandibular cysts was effective and safe.
