To show the feasibility of acquiring high-resolution sagittal ultrasound (US) images of the temporomandibular joint (TMJ).
We used commercially available US probes to assess the TMJ via a transoral soft tissue window to acquire sagittal images. Magnetic resonance imaging and clinical correlation were compared with the US findings by the consensus assessment of 2 of the senior investigators.
The sample was composed of 10 TMJs (6 participants) with an age range of 34 to 71 years and a male-female ratio of 3:1. The condyle and subcondylar surface were visible in 10 of 10 joints (100%), the disc in 7 of 10 joints (70%), and the pterygoid muscles in 6 of 10 joints (60%). In the 5 joints with magnetic resonance correlation, disc position and configuration were confirmed in all cases.
We show the first sagittal transoral sonograms of the TMJ disc and associated joint components.
展示获取颞下颌关节（TMJ）高分辨率矢状面超声（US）图像的可行性。
我们使用市售的超声探头，通过经口软组织窗口评估颞下颌关节以获取矢状面图像。由两位资深研究者通过共识评估，将磁共振成像及临床相关性与超声检查结果进行比较。
样本包括10个颞下颌关节（6名参与者），年龄范围为34至71岁，男女比例为3:1。10个关节中的10个（100%）可见髁突和髁突下表面，10个关节中的7个（70%）可见关节盘，10个关节中的6个（60%）可见翼状肌。在5个有磁共振相关性的关节中，所有病例均证实了关节盘的位置和形态。
我们展示了颞下颌关节盘及相关关节组成部分的首张矢状面经口超声图像。
