目的 探讨骨显像对口腔颌面部病变的诊断和鉴别诊断的临床价值。方法 用＾９９Ｔｃ＾ｍ－亚甲基二膦酸（ＭＤＰ）对５例正常人，１５例患者（３例下颌骨造釉细胞瘤、５例口腔内鳞状细胞癌、２例下颌胚胎型横纹肌肉瘤、１例舌血管瘤、１例下颌骨肉瘤、１例下颌骨囊肿、１例腮腺慢性炎症和１例拔牙后患者）进行三相骨显像、断层显像和半定量分析。结果 ３例下颌骨造釉细胞瘤均表现为＾９９Ｔｃ＾ｍ－ＭＤＰ浓聚，５例口腔鳞癌和下颌

The Preliminary application of bone imaging in oral and maxillofacial surgical patients

Objective To evaluate the clinical value of bone imaging for the diagnosis and differential diagnosis of oral and maxillofacial surgical patients and to clarify whether the mandible is invaded by the adjacent lesion Methods Routine planar three phase bone scintigraphy and semiquantitative mandibular tomography were performed on 5 controls and 15 patients Of these 15 patients, 3 cases were with ameloblastoma of mandible, 5 cases with intraoral squamous carcinoma, 2 cases with embryonal rhabdomyosarcoma, 1 case with hemangioma of tongue, 1 case with sarcoma of mandible, 1 case with mandibular cyst, 1 case with chronic parotitis and 1 postextraction patient Results All of 3 ameloblastomas of mandible showed high uptake of 99 Tc m MDP The mandibles invaded by intraoral squamous carcinoma and the embryonal rhabdomyosarcoma showed that the ratio of lesion to cervical vertibrae (L/C) was more than 1; the mandibles not invaded by intraoral squamous carcinoma and embryonal rhabdomyosarcoma showed that the L/C was less than 1; the tongue hemangioma showed a high uptake of 99 Tc m MDP in blood flow phase and blood pool phase, but no high uptake of 99 KG*2/3]Tc m MDP in bone imaging For the postextraction case, the alveolar bone showed a high uptake of 99 Tc m MDP in mandibular tomography, but L/C was less than 1; mandibular carcinomas showed a high uptake of 99 KG*2/3]Tc m MDP in mandibular tomography, L/C was 1 01 Conclusions Routine planar three phase bone scintigraphy and semiquantitative mandibular tomography is a useful method for the diagnosis and differential diagnosis of diseases in oral and maxillofacial surgery, and it is also helpful for finding out the limits of foci and invasion of mandibles by the lesions in adjacent tissue in clinical practising
