颌骨囊性病变的治疗通常采用造袋术或摘除术,小的囊肿或囊肿邻近的重要结构,如牙齿、鼻窦和下颌管未受累时,实行摘除术;较大囊肿及邻近结构受累时,需行造袋术;若随后行骨移植也可直接行摘除术。为了明确颌骨囊性病变的CT检查价值,作者比较了20例颌骨囊性病变的CT表现与平片(PFR)所见,并进行评分与统计学分析。CT检查采用横断薄层扫描,间隔1mm,重叠1.2mm;范围包括整个上颌骨和下颌骨,而后行颊舌平面和全景重建。按1:1的比例在图象上测量,需估价下列参
The treatment of cystic lesions of the jaw usually use bagging or enucleation, a small cyst or cyst adjacent to the important structures, such as teeth, sinus and mandibular tube without involvement, the implementation of enucleation; larger cysts and adjacent structures involved, Need to line bagging; if the subsequent line of bone transplantation can also be directly removed. In order to clarify the value of CT examination of cystic lesions of the jaw, the authors compared CT findings and plain film (PFR) findings of 20 cases of cystic lesions of the jaws, and scored and statistically analyzed. The CT scan was performed with a transverse lamellar scan at an interval of 1 mm and an overlap of 1.2 mm; the range included the entire maxilla and mandible, followed by a bucco-lingual plane and panoramic reconstruction. According to the ratio of 1: 1 on the image measurement, the following parameters to be assessed
