AbstractTo evaluate the clinical results of endoscopic endonasal surgical dacryocystorhinostomy (EES-DCR) as team work by an ophthalmologist and an ear-nose-throat (ENT) surgeon and the appropriate selection of the patients this study performed.All candidates for DCR underwent computed tomography (CT) scan of the paranasal sinuses (PNS). Patients who did not want a scar on the medial canthus skin or who did not have intranasal problems received EES-DCR, which was performed as team work by an ophthalmologist and an ENT surgeon. Surgical success was the resolution of epiphora (i.e., functional success) and free passage of the fluid on irrigation (i.e., anatomical success) by six months after surgery.One hundred twenty-eight patients underwent EES-DCR. Six months following the operation, six patients underwent surgical failure (three cases of anatomical failure and three cases of functional failure); the success rate was therefore 95.3%. The most common intranasal problems that led to EES-DCR were sinusitis, septal deviation, close proximity of the agger nasi to the lacrimal bone, and concha bullosa; moreover, 15.5% of patients selected EES-DCR for cosmetic reasons. Cooperation between ophthalmologists and ENT surgeons in the preoperative assessment of patients with epiphora before EES-DCR increases its success rate, and it may replace external DCR in some patients.
