The disc is attached to the temporal bone and condyle posteriorly by elastic and loose connective tissue; this tissue is also known as the retrodiscal soft tissue or the bilaminar zone.
In 1979, McCarty et al reported a 94% success rate for disc-repositioning surgery; their technique involved removing 3 to 4 mm of the posterosuperior condylar surface and a posterior wedge resection (2 mm) of the bilaminar zone with suture reapproximation (9).
Posteriorly, the bilaminar zone attaches the disk and capsule to the condyle and temporal bone.
As the fibers of the posterior bilaminar zone loosen, the disk no longer reduces.
