Thirty-nine patients (forty-four joints) who had been diagnosed as havings meniscus
perforation of the temporomandibular joint by inferior joint spate arthrography and had
been treated by surgical procedures were evaluated retrospectively. Information of
clinical findings, arthroto-mographic findings and surgical findings was cellected on a
standardized form and evaluated.
The results were as follows:
1. On the 34 patients of 38 joints which were surgically confirmed perforation of
meniscus or its attachments of the temporonlandibular joint, there were 29 females and
5 males (5.8 : 1).
The average age was 36 years (range 17 to 70).
2. The common clinical findings of group that had meniscus displacement without
reduction and with perforation were pain on the affected joint and limitation of mouth
opening. In the group showing meniscus displacement with reduction and with
perforation the common clinical findings were pain and clicking on the affected joint.
3. 32 joints (84.2%) were arthrotomographically anterior meniscus displacement without
reduction and with perforation, 6 points (15.8%) showed anterior meniscus displacement
with reduction and with perforation.
4. Joints categorized arthrotomographically as having meniscus displacement without
reduction and with perforation were less likely to have full translation of the condyle in
comparison with the normal or meniscus displacement with reduction and with
perforation groups.(p<0.05)
5. The arthrographic findings of 44 joints having meniscus perforation were compared
with surgical findings, there were 6 false positive findings of meniscus perforation, the
reliability of arthrographic findings of meniscus perforation was a 86.4% correlation with
surgical findings.
6. On the site of perforations of 38 joints which were surgically confirmed perforation
of meniscus or its attachments, twenty-three of perforations (60.5%) were in location at
the junction of the meniscus and posterior attachment, forteen (36.9%) were located at
the posterior attachment and one (2.6%) was at the meniscus itself.
