摘要
Abstract
Objective This study aims to observe the clinical effect of bone plate reduction in combination with a re-sorbable plate on large mandibular cysts.Methods Between October 2017 and September 2022,patients with large mandibular cysts in the presence of labial and buccal cortical bone were involved in the study.Intraoral approach was performed for bone plate reduction.Cone beam computed tomography(CBCT)scan was reviewed at 3,6,and 9 months postoperatively to observe postoperative complications.Osteogenic results were assessed at these times to determine the clinical outcomes of this procedure.Results Eleven cases with large mandibular cysts in the presence of cortical bone were evaluated.The average thickness of the cortical bone on the labial and buccal sides was measured to be about(1.98±0.37)mm before surgery,with a mean value of(0.73±0.17)mm at the thinnest part of the plate and up to 0.51 mm at the thinnest part of the plate.The cystic cavities were well re-vealed during the surgeries,which were completed suc-cessfully.Postoperatively,the wounds healed in one stage without infection.The percentages of cyst shrinkage were 20.01%,41.76%,and 73.41%at 3,6,and 9 months after surgery,respectively.Quantitative measurement of bone mineral density in the jaws by CBCT with MIMICS software.The bone mineral densities of the adult bone were 313.78,555.85,and 657.45 HU at the 3,6,and 9 month time intervals,respectively.No significant change in the patient's maxillofacial appearance were observed from the preoperative period as assessed by the patient's and observer's visual analog scale.Conclusion Bone plate reduction is an effective treatment for large mandibular cysts of the oral and maxillofacial re-gion with the presence of cortical bone.关键词
