Obstruction of the lacrimal drainage apparatus may result in excessive tearing or epiphora. This may occur as a result of a traumatic injury or accumulation of debris, mucus, or pus. In nuclear dacryoscintigraphy, a radioactive solution is introduced into the conjunctival sac by pipette and allowed to follow the flow of the tear solution through the lacrimal drainage system. This article will review normal lacrimal anatomy and indications for nuclear dacryoscintigraphy in oral and maxillofacial surgery.
泪道引流装置阻塞可能导致流泪过多或溢泪。这可能是由外伤或碎屑、黏液或脓液积聚所致。在核素泪囊造影术中，通过滴管将放射性溶液引入结膜囊，并使其随泪液通过泪道引流系统流动。本文将综述正常泪道解剖结构以及口腔颌面外科中核素泪囊造影术的适应证。
