探索经口对颞下颌关节进行斜矢状位超声成像的可行性.选取2019年2—5月于解放军总医院海南医院接受住院医师规范化培训的志愿者6名,其中5名经MRI证实双侧颞下颌关节结构正常,1名为双侧关节盘前移位,用拐杖形超声探头经上颌前庭沟和颊部软组织之间进入颊廊直至上颌结节后外方黏膜,对颞下颌关节进行斜矢状位超声扫描,每名志愿者均扫描双侧关节.6名志愿者均顺利完成超声扫描,12侧关节的超声图像均可清晰辨认髁突、翼外肌上下头、上颌静脉和关节盘.经口对颞下颌关节进行斜矢状位超声成像具备一定的可行性.

This pilot study aimed to investigate the feasibility of trans?oral ultrasonography of the temporomandibular joint (TMJ) in oblique sagittal plane. Six volunteers who were receiving residency training at Hainan Hospital of General Hospital of Chinese PLA were recruited into this study, five of them had normal TMJ and one had anterior displaced disc all of which had been confirmed by MRI. A hockey?stick?shaped ultrasound probe was placed between the cheek and maxilla to push against the mucosa lateral to posterior maxillary tuberosity, and every volunteer underwent bilateral scans. The sonographic imaging were completed successfully on the six volunteers; the condyle, the superior and the inferior head of the lateral pterygoid muscle, the disc and the maxillary vein were clearly identified in all the twelve ultrasonographic scans. The feasibility of trans?oral ultrasonography of TMJ in oblique sagittal plane was confirmed.
