Abstract

著者는 1974年에서 1984年까지 서울大學校齒科大學病院에 來院하여 顎關節强直症으로
判明된 患者 48名을 對象으로 하여 이 中에서 片側性顎關節强直症患者의
orthopantomograph 31장과 記錄을 찾아 볼 수 있었던 患者의 記錄을 調査硏究하여 다음과
같은 結論을 얻었다.
1. 全體患者 48名中男性이 23名, 女性이 25名이었고 65%의 達(달).者(자)가 1∼10歲群
에서 發生했으며 發生平均年齡은 11.7歲平均期間은 11.7年이었다.
2. 片側性으로 罹患된 患者가 39名(81.3%) 兩側性이 9名(18.7%)이었고 片側性中에서 左
側顎關節에 罹患된 患者가 20名, 右側이 19名이었다.
3. 發生原因은 外傷이 11名(57.9%), 感染이 4名(21.2%), arthritis 1名(5.2%), 手術이 1名
(5.2%), 알 수 없었던 境遇가 2名(10.5%)의 順이었다.
4. 患者의 主訴는 開口困難이 18名(78.3%), 顔貌變形이 4名(17.4%), 齒牙의 疼痛이 1名
(4.3%)의 順이었다.
5. 放射線學的所見에 의한 下顎骨의 形態變化
(a) 下顎枝의 길이는 强直症에 罹患된 側이 反對側보다 짧았고 兩側 모두 正常値보다
짧았다
(b) 下顎體의 길이는 强直症에 罹患된 側이 反對側보다 길었고 兩側 모두 正常値보다
길었으며 下顎切痕의 깊이와 關係가 있었다.
(c) 下顎孔을 基準으로 한 下顎枝의 上下部比率은 强直症에 罹患된 側이 反對側보다
작았고 兩側 모두 正常値보다 짧았다.
(d) 下顎切痕의 깊이와 下顎枝後緣의 彎油의 깊이는 强直症에 罹患된 側이 反對側보다
훨씬 컸다.
(e) 下顎角은 强直症에 罹患된 側이 反對側보다 컸고 兩側 모두 正常値보다 작았다.
#초록#
The auther studied clinically and radiologically 48 cases which had been diagnosed as
TMJ ankylosis in SNUDH.
The purpose of this study is to analyse clinical features of TMJ ankylosis and to
evaluate the effect of TMJ ankylosis on the growth of the mandible.
The obtained results were as follows:
1. Total 48 cases of TMJ ankylosis patients consist of 23 males and 25 females.
65 percent of all cases of TMJ ankylosis occurred in patients between 1 and 10 years
of age.
The average age at the onset of ankylosis was 11.7 and average duration at the time
of examination was 11.7 years.
2. Unilateral akylosis (81.3%) was more frequent than bilateral ankylosis (18.7%).
3. Trauma (57.9%) and infection (21.2%) were main etiology.
4. Inability to open the mouth (78.3%) and facial asymmetry (17.4%) were main chief
complaints.
5. Mandibular morphology through radiographic features.
(a) In TMJ ankylosis patients the ramus length of the ankylosed side was shorter
than that of the non-ankylosed side. Comparing with the control group, ramus length of
the each side was shorter than normal value.
(b) The partial body length of the ankylosed side was longer than that of the
non-ankylosed side. Comparing with the control group, partial body length of the each
side was longer than normal value.
Partial body length was related with antegonial notch depth.
(c) Ratio of upper and lower ramus length at the level of mandibular foramen was
smaller in ankylosed side than in non-ankylosed side.
(d) Antegonial notch depth and ramus posterior contour depth were deeper in
ankylosed side than in non-ankylosed side and those of bothsides were deeper than
normal value.
(e) Gonial angle in ankylosed side was larger than in non-ankylosed side and that in
both sides was smaller than normal value.
