Dacryocystorhinostomy (DCR) remains the surgery of choice for the treatment of epiphora secondary to nasolacrimal duct (NLD) obstruction. It involves creating a direct soft-tissue anastomosis between the lacrimal sac and the ipsilateral nasal cavity, via an osteotomy created by removal of the floor of the lacrimal fossa and surrounding bone. Successful surgery clearly requires the presence of a nasal space and absence of this poses a surgical challenge. We describe three patients with absent nasal cavity on the side of lacrimal obstruction, where DCR was performed by the creation of an anastomosis between the lacrimal sac and the contralateral nasal space.
泪囊鼻腔吻合术（DCR）仍然是治疗鼻泪管（NLD）阻塞继发溢泪的首选手术。该手术通过去除泪囊窝底部及周围骨质形成截骨，在泪囊与同侧鼻腔之间建立直接的软组织吻合。成功的手术显然需要有鼻腔空间，而缺乏鼻腔空间则带来了手术挑战。我们描述了3例泪道阻塞侧鼻腔缺失的患者，在这些病例中，通过在泪囊与对侧鼻腔空间之间建立吻合进行了泪囊鼻腔吻合术。
