開窓部骨片を復位させた下顎臼歯部顎骨内病変摘出法 : 骨欠損部の骨形成に関するCT画像による評価 Surgical removal of a lesion from the posterior part of the mandible with replacement of the bone fragment to the resection site : Evaluation of bone formation in the mandibular defect by computed tomography
This report describes the technique for and clinical outcome of removal of a lesion from the posterior region of the mandible. Removal of an intramaxillary lesion requires resection of the surrounding cortical bone. We describe how a block of cortical bone was completely resected by corticotomy. After surgery, the block bone was returned to the cavity. We used this technique in 11 patients who underwent radicular cystectomy with root resection, radicular cystectomy, removal of odontoma, and extraction of residual roots. Focal infection did not develop in any patient. There was also no evidence of resorption of replaced bone fragments in seven patients examined by 3-dimensional computed tomography. We conclude that temporarily removed buccal cortical bone could be replaced in its original site and was useful for the removal of lesions from the posterior part of the mandible.
