Operations for lengthening the columella can be classified into three groups on the basis of source of material: lip, nose, or ear. When seen in profile, the middle of the lip provides one-fourth to one-third of the forward projection of the columella as compared with the level of the alar bases. Complete bilateral cleft lips usually benefit from columellar lengthening, but symmetrical, incomplete clefts rarely require it. Ancillary procedures, such as correction of a retruded maxilla by Le Fort I osteotomy or by contour build-up, can enhance the overall result. Our experience with advancement of skin from the floor of the nose and ala [15], skin from the alar margins at the tip [7], prolabial advancement flaps, fork flaps, and composite earlobe grafts is reported.
根据材料来源，鼻小柱延长手术可分为三组：唇部、鼻部或耳部。从侧面看时，与鼻翼基部水平相比，唇部中部提供了鼻小柱向前突出的四分之一至三分之一。完全双侧唇裂通常受益于鼻小柱延长，但对称的不完全唇裂很少需要。辅助手术，如通过勒福Ⅰ型截骨术或轮廓塑形矫正上颌后缩，可提高整体效果。本文报道了我们使用来自鼻底和鼻翼的皮肤推进术[15]、鼻尖鼻翼边缘的皮肤推进术[7]、唇前推进皮瓣、叉状皮瓣和复合耳垂移植的经验。
