Internal derangement of the temporomandibular joint can be defined an an abnormal
relationships of the meniscus relative to the mandibular condyle, articuar fossa and
eminence. This may cause variable mandibular dysfunctions and pain. For diagnosis,
arthrography, computed tomography and magnetic resonance imaging are used. In this
study, the author reviewed 98 TMJs of 88 patients who were diagnosed as internal
derangement througth inferior joint spare arthrography at the department of Oral &
Maxillofacial Radiology, Dental Hospital Dankook university through 1986 to 1992. 98
TMJs consisting of 30 disc displcement with reduction, 48 disc displcement without
reduction and 20 perforation were studied about clinical and radiological findings.
The results were as follows:
1. Internal derangement was found most frequently in the 2nd 3rd decades and the
average age of perforation was higher than that of disc displcement with higher than
that of disc displcement with reduction. The sexual predilection was 2 times hiker in
females.
2. The most frequent chief complaints were TMJ sound in disc displcement with
reduction, pain and limitation of mouth opening in disc displcement without reduction
and pain in perforation. The duration of the chief complaints was longer in disc
displcement with reduction with than in preforation and disc displcemment without
reduction.
3. Reciprocal click was the most frequently TMJ sound in disc displcement with
reduction. History of joint sound in disc displacement without reduction an crepitus in
perforation was the most frequent one.
4. The average maximum opening was 45.4§® in disc displcement with reduction, 31.4
§® in disc displcement without reduction and 33.8mm in perforation.
5. In the centric occlusion, posterior condylar position was the most frequent in disc
displcement with reduction. posterior and concentric condylar position was frequent in
disc displacement without reduction, concentric and anterior condylar position in
perforation. At 1 inch opening the same position to articular eminence was most
frequently found in disc displcement with reduction, posterior position in disc
displcement without reduction, posterior and anterior position in perforation was
frequently found.
6. Bony changes, especially sclerosis and flattening, was most frequently found in
perforation.
