Abstract

Inferior joint space arthrograms of the temporomandibular joints of 31 healthy volunteers (62 joints) were obtained to determine normal arthrographic findings. The superior margin of the anterior recess was smooth and flat in 68% of the joints and concave in 32% with the subjects' mouths closed. The concavity was the result of the anterior ridge of the meniscus impinging on the contrast material. The concave impression could be distinguished easily from an anteriorly displaced meniscus on videotaped studies, which demonstrated a smooth transition of contrast material from the anterior to the posterior recess during opening of a subject's mouth. With the mouth open, the anterior recess decreased in size, appearing as a small, crescent-shaped collection of contrast material anterior to the head of the condyle in 52 joints (84%); it remained large in ten joints (16%) at maximal mouth opening. The configuration of the posterior recess was identical to that described previously; however, with the subjects' mouths closed, it was larger than the anterior recess, contrary to most previously reported results.
