摘　　要：AIM:To describe the role of endoscopic transnasal canaliculorhinostomy(ETC)in refractory common canalicular obstruction(CCO)associated with an absent or unidentifiable lacrimal sac.METHODS:The records of patients with refractory CCO who underwent ETC at the Eye Hospital of Wenzhou Medical University from October 2007 to December 2016 were retrospectively reviewed.RESULTS:Fifty-six patients(56 eyes)with refractory CCO were recruited into the study.Eight patients were excluded due to the presence of a residual lacrimal sac or failure to complete the follow-up duration.The anatomic and functional success rates were both 85.4%(41/48)at a mean follow-up of 18.6 mo.Five cases failed as a result of ostial synechia and two failed because of ostial obstruction by granulation.Postoperative complications included mild nasal bleeding in 5 cases,dried nasal feeling in 8 cases,and olfactory dysfunction in 4 cases.CONCLUSION:Although being surgically challenging,ETC has comparable findings to its external approach counterpart or conjunctivodacryocystorhinostomy(CDCR)with Jones tube.And it may prove to be a novel alternate surgical technique for patients with refractory CCO without identifiable lacrimal sac.
