摘　　要：目的:观察泪小管断裂后鼻侧断端位置与泪阜和内眦韧带的关系及其在泪小管断裂吻合术中的应用。方法:选取外伤性下泪小管断裂患者65例65眼,测量泪小管泪点至颞侧断端的距离,直视下寻找鼻侧断端,量化分析鼻侧断端与泪阜、内眦韧带的关系。结果:本组患者颞侧断端距离≤6mm者39眼,其中鼻侧断端位于泪阜区者35眼;颞侧断端距离>6mm者26眼,其中鼻侧断端位于内眦韧带区者24眼。泪阜区鼻侧断端距离泪阜下缘黏膜的垂直距离为2.1±0.7mm,内眦韧带区鼻侧断端距离皮肤面的垂直距离为3.5±1.2mm。结论:泪小管断裂后将鼻侧断端位置分为泪阜区和内眦韧带区,有助于寻找鼻侧断端位置。AIM:To investigate the positional relationship between the nasal ends of the lacerated lacrimal canaliculi,lacrimal caruncle,and medial canthal ligament,as well as its application in the lacrimal canalicular anastomosis.METHODS:Sixty-five patients with traumatic lower canalicular laceration were selected.The distance from the lacrimal punctum to the temporal end was measured.The nasal ends were found under direct vision,and the positional relationship between the nasal ends,lacrimal caruncle and medial canthal ligament were quantitatively analyzed.RESULTS:Totally 65 patients with canaliculus laceration,39 patients had a distance of less than 6mm from the lacrimal punctum to the temporal end,where the nasal ends of 35 patients were located in the lacrimal caruncle area.There were 26 cases in which the distance from the lacrimal punctum to the temporal end was greater than 6mm,where the nasal ends of 24 cases were located in the medial canthal ligament area.The vertical distance between the nasal ends in the lacrimal caruncle area and the lacrimal mucosa was 2.1±0.7mm,and the vertical distance between the nasal ends in the medial canthal ligament area and the skin edge was 3.5±1.2mm.CONCLUSION:The positions of nasal ends can be divided into the lacrimal caruncle area and the medial canthal ligament area,providing a basis for finding the nasal ends of the lacerated lacrimal canaliculi in the clinical practice.
