目的评价锥形束CT(CBCT)用于诊断颌下腺涎石病的临床价值。方法选择2013年1月至2014年12月在大连市中心医院口腔颌面外科就诊的颌下腺涎石病患者26例,进行下颌横断片、颌下腺侧位片和CBCT检查并定位涎石位置,行颌下腺导管切开取石术或颌下腺切除术。结果 4例为多发涎石,22例为单发涎石。8例涎石位于导管口,6例位于前磨牙区,5例位于磨牙区,3例位于腺门部,4例位于颌下腺内。涎石最大直径12 mm,最小直径5 mm,平均8.4 mm。距下颌骨内侧缘的平均距离为(8.5±2.7)mm。有3例在下颌横断片和颌下腺侧位片中未显影而在CBCT中显影。19例行颌下腺导管切开取石术,7例行颌下腺切除术。结论 CBCT可作为诊断颌下腺涎石病的常规有效手段,特别是对一些涎石较小、钙化不全病例具有很好的指导意义。
Objective To evaluate the clinical value of cone beam computed tomography (CBCT) in the diagnosis of submandibular gland. Methods From January 2013 to December 2014, 26 patients with submandibular gland salivosis undergoing oral and maxillofacial surgery in Dalian Central Hospital were enrolled. The mandibular transverse segments, lateral submandibular glands and CBCT were examined to determine the location of the salivary glands. Catheterization or submandibular gland resection. Results of 4 cases of multiple salivary stone, 22 cases of single saliva stone. 8 cases of salivary glands in the catheter port, 6 cases in the premolar area, 5 cases in the molar area, 3 cases in the glandular portal, 4 cases located in the submandibular gland. The largest diameter of saliva 12 mm, the smallest diameter of 5 mm, an average of 8.4 mm. The average distance from the medial margin of the mandible was (8.5 ± 2.7) mm. Three cases developed in CBCT without development in mandibular transverse and submandibular gland flaps. Nineteen patients underwent submandibular gastrectomy and seven patients underwent submandibular gland resection. Conclusion CBCT can be used as a routine and effective method in the diagnosis of submandibular gland sash disease, especially for some cases of salivary glands with poor calcification.
