Abstract
We performed three-dimensional reconstruction of facial CT scan images of patients with mandibular angle hypertrophy to explore the related factors of mandibular angle hypertrophy. At the same time, the article uses the results of three-dimensional reconstruction to simulate the clinical operation and obtain the final operation method. It was found that all patients were able to obtain the proper surgical plan from the three-dimensional reconstructed images and can get the hypertrophy factor of the mandibular angle. For this reason, we conclude that computer reconstruction simulation technology can obtain the tissue changes before and after osteotomy of mandibular angle hypertrophy and get the cause of hypertrophy. Three-dimensional reconstruction simulation technology is the best auxiliary diagnosis plan for the selection of mandibular angle surgery.
Highlights
Mandibular angle osteotomy is a common operation in facial contouring
Craniofacial surgery has been a hot topic for maxillofacial surgeons and computer experts. It improves the predictability of surgery and allows patients to understand the degree of deformity, correction methods, and postoperative effects visually and intuitively. is is conducive to strengthening doctor-patient communication [1]. ree-dimensional reconstruction based on DICOM data obtained from three-dimensional spiral computer tomography (CT) scanning is a mature method recognized internationally
Typical Cases. e patient Wang came to our hospital for mandibular angle hypertrophy osteotomy due to bilateral hypertrophy of the mandibular angle
Summary
Mandibular angle osteotomy is a common operation in facial contouring. To improve the accuracy of surgery, plastic surgeons are making continuous efforts. Craniofacial surgery has been a hot topic for maxillofacial surgeons and computer experts. It improves the predictability of surgery and allows patients to understand the degree of deformity, correction methods, and postoperative effects visually and intuitively. Ree-dimensional reconstruction based on DICOM data obtained from three-dimensional spiral CT scanning is a mature method recognized internationally. It has been applied in craniomaxillofacial surgery. To this end, this paper measures the geometric facial features before and after osteotomy of mandibular angle hypertrophy. We hope to explore a feasible way to improve the aesthetic effect and the accuracy of surgery
