The aim of this study is to elucidate innervation of the procerus muscle, which is attributed mainly to transverse lines on the radix nasi and indirectly to glabella frown line. Twenty-three hemifaces of Korean adult cadavers were dissected. In all specimens, the procerus muscle was supplied by the buccal branch of the facial nerve, which coursed infraorbitally. The number of the buccal branches varied: three in 47.8%, two in 47.8%, and one in 4.4% of the specimens. The buccal branch crosses the intercanthal line (nasion to the medial canthus) at approximately lateral one third. The nerve entrance was within a circle with a diameter of 5 mm and its center located 9 mm lateral and 10 mm superior from nasion. It was about a midpoint of lateral half of intercanthal line and lower one third between the intercanthal line and tangential line of the supraorbital rim. The anatomical knowledge might be contributive to depletion of transverse lines on the nasal bridge and function of the procerus muscle.
本研究旨在阐明降眉间肌的神经支配，该肌肉主要与鼻根部的横向皱纹有关，间接与眉间皱眉纹有关。对23例韩国成年尸体的半侧面部进行了解剖。在所有标本中，降眉间肌由面神经的颊支供应，该颊支在眶下走行。颊支的数量各不相同：47.8%的标本中有3支，47.8%的标本中有2支，4.4%的标本中有1支。颊支在大约内眦连线（鼻根至内眦）的外侧三分之一处穿过。神经入口位于一个直径为5mm的圆内，其圆心位于鼻根外侧9mm、上方10mm处。它大约位于内眦连线外侧一半的中点以及内眦连线与眶上缘切线之间下三分之一的位置。这些解剖学知识可能有助于消除鼻梁上的横向皱纹以及降眉间肌的功能。
