Although there has been a narrowing in the gap in successful functional outcomes between external and endonasal DCR, external DCR is still being frequently performed when cost, availability of additional surgical instruments and visual systems, surgeon's experience and preference are concerned. Nonetheless, skin incisions at the lateral nasal sidewall of the lower eyelid inevitably leave cutaneous scars. The purpose of this review is to evaluate the outcomes of current modified surgical practices that prevent a conspicuous scar in external DCR.
尽管外路和鼻内镜下泪囊鼻腔造口术（DCR）在成功实现功能预后方面的差距已有所缩小，但在考虑成本、额外手术器械和视觉系统的可用性、外科医生的经验和偏好时，外路DCR仍经常被采用。然而，下眼睑鼻外侧壁的皮肤切口不可避免地会留下皮肤瘢痕。本综述的目的是评估当前改良手术方法在外路DCR中预防明显瘢痕的效果。
