泪阜在下泪小管吻合术中定位意义

A study of orienting with lacrimal caruncle in lacrimal of canaliculus

目的了解泪阜在下泪小管断裂中的定位意义。方法测量泪小管近侧断端与泪阜的水平和垂直距离关系。结果下泪小管近侧断端大多位于泪阜下方1mm以内，鼻侧2mm以内，而且存在泪道断端被泪阜遮盖的可能。结论以泪阜作为定位参照，对于经外路的泪小管吻合术有助于进一步提高手术成功率。

Objective To research the value of orienting with lacrimal caruncle in repair of lacri- mal of canaliculus. Methods The distance between the nosal points of lacrimal of canaliculus and lac-rimal caruncle was measured horizontally and vertically. Results Great majority of the nosal points of lacrimal of canaliculus were smaller than lmm below lacrimal cartmcle, and smaller than 2mm to lacri-mal caruncle in nasalis, and the nosal points of lacrimal of canaliculus might be recovered by lacrimal earuncle. Conclusions Orienting with lacrimal caruncle is favorable for lacrimal of canaliculus.
