Detailed explanation-1: -Jaw deviation with the opening is usually due to the restricted motion of the injured joint while the healthy joint moves normally. This is often caused by a displaced or damaged disc. The opening will not be symmetrical and the chin will deviate toward the injured side.
Detailed explanation-2: -The most common type of temporomandibular joint (TMJ) dislocation is anterior dislocation, dislocations may however occur in any direction especially when associated with condylar fractures3, 6.
Detailed explanation-3: -Temperomandibular joint displacement, also known as internal disc derangement, is an abnormal relationship between the articular disc, the mandibular condyle and the mandibular fossa. The most frequent displacement of the disc is anterior to the mandibular condyle however, in rare cases it can be posteriorly.
