The purpose of the present study was to determine the locations of the infraorbital foramen and mental foramen based on soft-tissue landmarks to facilitate prediction of the locations of these structures during facial surgery.
Fifty embalmed cadavers (100 sides) of Koreans were dissected to expose the infraorbital foramen and mental foramen. The distances between the bilateral infraorbital foramina and between the mental foramina and the distances between the alae of the nose and between the corners of the mouth (cheilions) were measured directly on the cadavers, and the vertical and horizontal distances between the infraorbital foramen and mental foramen and the ala of the nose and cheilions, respectively, were measured indirectly on photographs.
The distance between the bilateral infraorbital foramina (54.9 +/- 3.4 mm) was greater than that between the bilateral mental foramina (47.2 +/- 5.5 mm). The infraorbital foramen was located 1.6 +/- 2.7 mm lateral and 14.1 +/- 2.8 mm superior to the ala of the nose. The distance between the ala of the nose and the infraorbital foramen was 15.9 +/- 2.8 mm, and the horizontal angle between these structures was 64.1 +/- 9.9 degrees laterosuperiorly. The mental foramen was located 20.4 +/- 3.9 mm inferior and 3.3 +/- 2.9 mm medial to the cheilions. The distance between the cheilions and mental foramen was 20.9 +/- 3.8 mm, and the vertical angle between these structures was 9.2 +/- 8.1 degrees inferomedially.
This study provides data that will be useful in predicting the locations of the infraorbital foramen and mental foramen when used together with hard-tissue landmarks. These data may be particularly helpful for facial surgery in patients with missing teeth.
本研究的目的是基于软组织标志确定眶下孔和颏孔的位置，以便于在面部手术中预测这些结构的位置。
解剖50具韩国防腐尸体（100侧）以暴露眶下孔和颏孔。在尸体上直接测量双侧眶下孔之间以及颏孔之间的距离，以及鼻翼之间和口角（唇裂）之间的距离，并在照片上间接测量眶下孔和颏孔与鼻翼和口角之间的垂直和水平距离。
双侧眶下孔之间的距离（54.9±3.4mm）大于双侧颏孔之间的距离（47.2±5.5mm）。眶下孔位于鼻翼外侧1.6±2.7mm、上方14.1±2.8mm处。鼻翼与眶下孔之间的距离为15.9±2.8mm，这些结构之间的水平角度为外上64.1±9.9度。颏孔位于口角下方20.4±3.9mm、内侧3.3±2.9mm处。口角与颏孔之间的距离为20.9±3.8mm，这些结构之间的垂直角度为内下9.2±8.1度。
本研究提供的数据在与硬组织标志一起使用时，将有助于预测眶下孔和颏孔的位置。这些数据可能对缺牙患者的面部手术特别有帮助。
