Endoscopic Dacryocystorhinostomy (DCR) is an established surgical technique for the management of peripheral nasolacrimal duct (NLD) obstruction. Its main points are the correct identification of the lacrimal sac and the execution of surgical procedures that allow a rapid and accurate healing of the surgical field. The main endoscopic landmarks used for the identification of the lacrimal sac are the middle turbinate and the maxillary line. However, in some cases, this procedure can be difficult due to several factors (e.g. anatomical variations, former surgery). In the present study, a variation of “classic” endoscopic DCR, named “retrograde” endoscopic endonasal DCR (rDCR), is described. rDCR is performed through the quick identification of the NLD at the level of the most anterior insertion of the inferior turbinate in the lateral nasal wall. In most cases, at this level only a very thin shell of bone is present (crack point), easily fractured by using blunt angled dissector. The duct is then followed upward along its course by removing the overlying bone in order to correctly identify the lacrimal sac and unequivocally drill along the lacrimal pathway. This technique proved to be a safe, quick and effective procedure, even in patients with difficult anatomy.

Abstract

Endoscopic Dacryocystorhinostomy (DCR) is an established surgical technique for the management of peripheral nasolacrimal duct (NLD) obstruction. Its main points are the correct identification of the lacrimal sac and the execution of surgical procedures that allow a rapid and accurate healing of the surgical field. The main endoscopic landmarks used for the identification of the lacrimal sac are the middle turbinate and the maxillary line. However, in some cases, this procedure can be difficult due to several factors (e.g. anatomical variations, former surgery). In the present study, a variation of “classic” endoscopic DCR, named “retrograde” endoscopic endonasal DCR (rDCR), is described. rDCR is performed through the quick identification of the NLD at the level of the most anterior insertion of the inferior turbinate in the lateral nasal wall. In most cases, at this level only a very thin shell of bone is present (crack point), easily fractured by using blunt angled dissector. The duct is then followed upward along its course by removing the overlying bone in order to correctly identify the lacrimal sac and unequivocally drill along the lacrimal pathway. This technique proved to be a safe, quick and effective procedure, even in patients with difficult anatomy.
