ANAMNESIS / SYMPTOMS:
A 52 year old patient shows a big swelling in the area of the right upper jaw. The swelling continues on the cheek and tongue. The symptoms are increasing for one week. In spite of antibiosis there is no improvement.


FINDINGS:
In comparison of both sides on a longitudinal plane a thickened and hypoechoic masseter muscle of the right side is visible. Caudal of the masseter muscle the hypoechoic surface of the mandible is visualized. The surface shows an interruption on a distance of about 6 mm. When pressure is exerted with the transducer moving reflections are visible that disappear into a hypoechoic or echofree space between masseter muscle and lower jaw bone.


DIAGNOSIS:
The patient is suspected of suffering from a dentogenous osteomyelitis with perforation through the mandible. An osseus defect with abscess formation is visible in the area of the mandibular ramus. Further orosurgical diagnosis confirmed the tentative diagnosis.
