After failed implant dacrocystorhinostomy (DCR) first patient underwent endoscopic DCR with removal of embedded intracystic implant (Pawar stent). After one-year, epiphora recurred due to a migrated second stent obstructing the neo-ostium. Second case with prelacrimal pneumatisation had failed left implant DCR due to misplaced stent in the middle meatus. Endoscopic DCR as primary surgery for dacryocystitis avoids such complications.
在植入式泪囊鼻腔造口术（DCR）失败后，首例患者接受了内镜下DCR并取出了嵌入囊内的植入物（Pawar支架）。一年后，由于第二个支架移位阻塞了新造口，溢泪复发。第二例患者泪前气肿，因中鼻道支架位置不当导致左侧植入式DCR失败。内镜下DCR作为泪囊炎的初次手术可避免此类并发症。
