Dacryoliths are concretions formed in the lacrimal sac from cellular debris and proteins, which may calcify and cause further obstruction of the nasolacrimal pathway. Dacryoliths are often underlying contributors in cases of intermittent or chronic dacryocystitis (i.e. nasolacrimal sac inflammation, characterised by epiphora, pain, erythema, sac dilation and lacrimal punctum swelling).
We report an unusual case of dacryolith resulting in obstructive epiphora, managed via an endonasal endoscopic approach.
Case report and literature review pertaining to dacryolith.
A 54-year-old man attended the multidisciplinary nasolacrimal clinic due to recurrent epiphora. Obstructive epiphora secondary to chronic dacryocystitis was diagnosed. He underwent endonasal endoscopic dacryocystorhinostomy. Intra-operatively, a large dacryolith was found to be the cause of epiphora.
Dacryolith is an unusual cause of nasolacrimal duct obstruction. This case highlights this unusual cause, and the relevant diagnostic investigations. This case also illustrates successful endonasal endoscopic management, rather than an external, open approach.
泪石是由细胞碎片和蛋白质在泪囊中形成的凝结物，可能会钙化并导致鼻泪管进一步阻塞。泪石通常是间歇性或慢性泪囊炎（即鼻泪囊炎症，其特征为溢泪、疼痛、红斑、泪囊扩张和泪小点肿胀）病例的潜在病因。
我们报告一例因泪石导致阻塞性溢泪的罕见病例，通过鼻内镜手术进行治疗。
关于泪石的病例报告及文献综述。
一名54岁男性因反复溢泪就诊于多学科鼻泪科门诊。诊断为慢性泪囊炎继发阻塞性溢泪。他接受了鼻内镜下泪囊鼻腔造口术。术中发现一块大的泪石是溢泪的原因。
泪石是鼻泪管阻塞的罕见病因。本病例突出了这一罕见病因及相关诊断检查。本病例还展示了鼻内镜手术治疗的成功，而非外部开放手术。
