Ta. Dorsay et Ra. Youngberg, CINE MRI OF THE TMJ - NEED FOR INITIAL CLOSED MOUTH IMAGES WITHOUT THE BURNETT DEVICE, Journal of computer assisted tomography, 19(1), 1995, pp. 163-164
Objective: To evaluate the Burnett device when studying functional and
morphologic aspects of internal derangements of the temporomandibular
joint (TMJ) with cine MRI. Materials and Methods: A patient with clic
ks in the TMJ cycle was studied with dynamic cine MRI both prior to th
e placement of the Burnett device and with the Burnett device in posit
ion. Results: Review of MRI revealed clear anterior displacement of th
e disk in relation to the condylar head in true closed mouth position
without the Burnett device in place. Conclusion: Closed mouth off-sagi
ttal imaging of the disk in the closed mouth position should be includ
ed prior to appliance placement to detect anterior displacements with
very early recapture.
