Sodium hyaluronate (Healon) injected into the lacrimal sac, facilitates a full-thickness cut of the lacrimal sac in cases in which it is difficult to identify the lumen of the sac. The sodium hyaluronate does not stain tissues, is effective for hemostasis, and is easily irrigated. A full-thickness cut of the lacrimal sac is required to ensure exact mucosal suturing in dacryocystorhinostomy. However, in cases involving a hypertrophic sac wall, a small lumen of the sac, or earlier perforation of the sac, it is sometimes difficult to identify the lumen during surgery. We describe how sodium hyaluronate, injected into the sac via a canaliculus, can facilitate identifying the lumen in this situation.
将透明质酸钠（Healon）注入泪囊，在难以识别泪囊管腔的情况下，有助于对泪囊进行全层切开。透明质酸钠不使组织染色，止血效果良好，且易于冲洗。泪囊全层切开是确保泪囊鼻腔吻合术中精确黏膜缝合所必需的。然而，在泪囊壁肥厚、泪囊管腔较小或泪囊早期穿孔的情况下，手术中有时难以识别管腔。我们描述了如何通过泪小管将透明质酸钠注入泪囊，在这种情况下有助于识别管腔。
