Abstract

著者는 唾液際에 對한 病歷이 없고, 全身狀態가 良好한 正常成人 37名을 對象으로 等唾
液腺造影術을 施行하여 얻은 顎下腺造影寫眞 132枚에서 正常顎下腺의 導管 및 腺實質의 解
剖學的形態와 周圍組織과의 關係를 究明하고자 本硏究를 試圓한 바 다음과 같은 結論을
얻었다.
1. 顎下腺排泄管의 直涇은 遠心部에서 平均 1.96㎜이었고, 幽門部에서는 平均 2.71㎜로 遠
心部의 直經이 작았다.
2 顎下腺排泄管의 길이는 平對 42.02㎜이었다.
3. 顎下腺排泄管이 下顎下緣과 이루는 角度는 平均 35.67度이었고, 顎舌骨筋의 後方境界
部에서 排泄管에 依하여 이루어지는 角度는 平均 103.05度이었다.
4. 韻不腺排泄管의 形態에 따른 分布는 曲線型이 39.39%, 直線型이 16.67%, S宇型이
22.73%, V字型이 21.21%이었으며, 排泄管의 走行狀態에 따른 分布는 平滑型이 83.33% 이
었고, 蛇型이 16.67%이었다.
5. 顎下腺實質의 크기는 上下間의 平均直徑이 45.49㎜, 前後間의 平均直徑이 43.56㎜, 內
外側間의 平均直徑이 28.85㎜이었으며, 下顎隅角部水準에서의 下方延長은 그 平均距離가 駱
33.65㎜이었다.
6 顎下腺實質의 朧胞가 잘 觀察된 例는 77.28%이었고, 微細導管까지 明瞭하게 觀察된 例
는 50.06%이었다.
7 顎下腺의 導管 및 腺實質의 크기와 形態에 있어서의 左右差異는 認定되지 않았으며, 個
人差는 甚하였다.
#초록#
The aim of this study was to establish the diagnostic criteria of normal
submandibular glands in adults.
Materials included 132 sialograms of selected person from 23 to 28 years outage.
In subjects each variable was measured and evaluated statistically introducing 18
items respectively.
Conclusions from this study were as follows.
1. The mean diameter of main duct was 1.96mm in distal end and 2.71mm in hilar
end, so the diameter of distal end was smaller than that of hilar end in submandibular
glands.
2. The mean length of main duct was 42.02㎜ in submandibular glands.
3. The mean angle of main duct was 35.67 degrees with inferior border of mandible
and 103.05 degrees at posterior mylohyoid portion.
4. In configurations following shape of main duct, those revealed that 39.39% of cases
of the curvilinear type, 16.67% of cases of the linear type, 22.73% of cases of the
sigmiod type and 21.21% of cases of the angular type. And in configurations following
course of main duct, those revealed that 83.33% of cases of the smooth type and 16.67%
of cases of the tortuous type.
5. The mean caliber of submandibular glands was 45.59mm in superoinferior height,
43.56㎜ In anteroposterior width, 28.85㎜ in mediolateral width and 33.65㎜ in extent
below mandibular angle.
6. Well-delineated acinar parenchyme was observed in 77.28% of cases and
well-defined tertiary ducts In 50.06% of cases.
7. There were no differences between right and left submandibular glands in size and
shape of main duct and parenchymal portion , but there were great variations in each
individual.
