To evaluate of the relationship between the TMJ disorder and the vertical mandibular
asymmetry, the author analyzed the differences between condylar heights, ramus heights
of and mandibular heights of both sides.
All measurements were performed with a digital micrometer on the panoramic
radiographs of 36 TMJ disorder patients and 30 normal control group. The differences
were e3[pressed in millimeters and percentage using the following formula ; ¦¢
(R-L)/(R+L)¦¢¡¿100%
The results were as follows :
1. The condylar height difference was greater of in patient group (136¡¾1.66 §®) than
that of in control group (1.22¡¾0.85 §®)(p<0.05).
But there was no significant difference in the condylar height ratio difference between
patient group(11.67¡¾11.44%) and control group (7.64¡¾6.21%) (p>0.05).
2. The ramus height difference and ramus height ratio difference of patient group
(4.52¡¾3.70 §® 4.39¡¾3.49%) were greater than those of control group (2.64¡¾2.13 §®, 2.46
¡¾2.02%)(p<0.05, p<0,01).
3. The mandibular height difference and mandibular height ratio difference of patient
group (432¡¾3.52 §®, 3.59¡¾2.81%) were greater than those of control group (2.57¡¾2.46
§®, 2.01¡¾1.95%)(p<0.05).
4. The ratio difference in condyle height to ramus height and condylar height to
mandibular height of patient group (5.01¡¾4.13%, 3.36¡¾2.88%) were greater than those of
control group (2.33¡¾1.78%, 1.90¡¾1.40%) (p<0.01).
