Combined or Staged Temporomandibular Joint and Orthognathic Surgery for Patients with Internal Derangement and Dentofacial Deformities.

Patients with internal derangement of the temporomandibular joint and dentofacial deformities need appropriate evaluation for both conditions. Correct diagnosis of internal derangement is vital in determining the correct orthognathic surgery plan, and it is particularly important to differentiate between myofascial dysfunction and intra-articular joint problems. Depending on the stage of internal derangement, patients may need treatment for temporomandibular dysfunction symptomatically, staged, or concurrently with orthognathic surgery.
