Nasolacrimal duct obstactrcphinlectomy proponed by Zheng(huansiis a simple and effect operation to treat the chronic dacryoeystitiis.Inour hospital this surgery was accepted instead of dacryocystorhinostomy.In this paper the authors described some problems which might he metin the course of the operation,i.e.the bleeding,defined and incised thelacrimal sac,explo-ring the position of the beginning of the nasolacrim-al duct,the progress in the nasolacrimal duct with the trephine and thepostoperative infection.The result in histopathologic studjes of the incisedtissues from the nasolacrimal duct obstraction was predominantly infLam-matory tissues.Nasolacriml duct obstactrehinlectomy was a surgerywhich could incise these inflammatory tissues and therefore cure the chr-onic dacryocyocystitis.
