Locating the cut medial ends of canaliculi after trauma or surgery can be difficult. In cases of double canalicular or common canalicular lacerations, injection of sodium hyaluronate (Healon) directly into the lacrimal sac may help pinpoint the medial openings.
创伤或手术后定位泪小管内侧断端可能很困难。在双泪小管或共同泪小管撕裂的情况下，直接向泪囊内注射透明质酸钠（Healon）可能有助于确定内侧开口。
