The invention relates to a simplified fronto-sagittal and two-dimensional ultrasound apparatus exclusively intended for the exploration of the two right and left temporo-mandibular articulations (ATM) at rest or during mandibular movement, in the case of stomatology and traumatology exams. The calculation and the adjustment of the parameters for obtaining a displayed image of the region of the temporo-mandibular articulations is already done during the design step. Accordingly, the invention provides an apparatus with small dimensions and a lower cost relative to traditional ultrasound apparatuses, which will promote its use in medical practices both from a logistic and financial point of view. This exploration method has a low cost, does not require any particular preparation or hospitalisation for the patient, does not include any risks due to X-rays, and has no known side effects. The apparatus includes a quadruple hinged ultrasound probe (right and left) (FIG. 3, no1 et no3), two of which are connected to a flexible and telescopic extra-oral and semi-circular bearing (FIG. 3, no2) and are placed around the head of a patient, while two other ones are connected to a flexible and telescopic intra-oral and semi-circular bearing (FIG. 3, no4) adapted to the upper jaw. The bearings are connected to a screen (FIG. 3, no5) for simultaneously displaying the right and left ATM and for comparing them both in the sagittal and frontal planes. A printer (FIG. 3, no6) can be used for reproducing the selected images on paper. The device of the invention is particularly intended for use in medical practices and in hospital stomatology and traumatology wards for instantaneously displaying the temporo-mandibular articulations.
