MRI and arthrograms were used to diagnose the disc displacement of
temporomandibular joint, but most of these trials focused on the anterior disc
displacement. The discs could be displaced laterally or medially and in some case this
sideway displacement may play a role as a main problem of temporomandibular disorder.
In this study, 45 patients(31 unaffected sites, 59 affected sites) and 20 asymptomatic
volunteers' sagittal and coronal MRI views were reviewed, then some results were
found as follows
1. In sagittal plan, anterior disc displacements were found 15% in normal sites, 45% in
unaffected sites and 69% in affected sites.
2. In coronal plan, sideways disc displacements were found 15% as medial in normal,
6% as medial and 13% as lateral in unaffected, 8% as medial and 14% as lateral
diaplacement in affected sites.
3. In asymptomatic sites involving unaffected sites, medial disc displacements(11.3%)
but in symptomatic joints, lateral disc displacements(13.8%) were prevalent.
4. The sideways disc displacement were observed 10.1% as medial and 2.9% as lateral
dispalcement without and 9.8% as medial and 16.4% lateral dispalcements with anterior
disc displacement. And, the coronal views of MRI were beneficial to evaluate the
sideways disc displacement.
Further studies may be needed on evaluation of the relations between sideways
displacements and clinical symptoms or the treatment results.
