内眦韧带撕脱或断离修复术

[适应证]

内眦韧带撕脱或断离导致眦角向颞下移位,即远内眦畸形。

[术前准备及麻醉]

1.冲洗泪道了解有无慢性泪囊炎,如有粘液脓性分泌物洗出,应先作泪囊摘出术。

2.术前应作X线检查,了解局部骨质畸形情况,为制订手术方案提供重要依据。

3.术前鼻腔内滴以氯麻滴鼻剂。

眶下神经、滑车上神经、滑车下神经阻滞麻醉。

[手术步骤]

1.靠近鼻根部作内眦部皮肤的弧形切口,长约2~2.5cm。用钝头剪向下分离软组织达泪骨,将其充分暴露。清除局部瘢痕组织,松解瘢痕组织和其他原因所致的一切牵引力。寻找内眦韧带两侧断端(图1)。

2.如果发现原韧带断端,可用尼龙缝线或不锈钢细钢丝予以缝合。如发现部分韧带断裂,可将韧带的断端缝合于残留的内眦韧带上。

3.假若原内眦韧带残端确实无法寻找到,可于后泪嵴用骨钻作两个骨孔,相距0.5cm,钻孔时尽量不穿透鼻粘膜(图2)。

4.不锈钢丝由一侧骨孔穿入,于鼻粘膜和骨壁间通过,由另侧骨孔穿出,与相当于内眦水平的比较坚韧的结缔组织缝合,作扭转固定(图3)。

5.切除切口颞侧过多的软组织和皮肤,分层缝合眼轮匝肌与皮肤。

[术中注意事项]

1.将内眦韧带断端固定于鼻侧眶缘时,可以略偏高一些,外貌可以更好。

2.用骨钻钻孔,以及用不锈钢丝穿越时,尽量注意不要穿透鼻粘膜。

[术后处理]

术后压迫包扎,48小时后首次换药,7天后拆除皮肤缝线。继续用弹力绷带压迫包扎1~2周。

术后全身给予抗生素。
