PURPOSE:: To evaluate the outcomes of endoscopic dacryocystorhinostomy (eDCR) with and without the use of ultrasonic bone aspirator (UBA; Sonopet). METHODS:: A retrospective, institutional review board approved chart review of all eDCRs over 49 months. Data included demographics, indication/etiologic factors of nasolacrimal duct obstruction, comorbidities, intraoperative findings, epiphora symptoms pre- and postoperatively, and complications. Patients were grouped in eDCR with or without UBA. RESULTS:: One hundred and twenty-three primary eDCRs in 99 patients were included, 59 with UBA and 64 without UBA. Most patients were Caucasians (80.8%) and women (72.0%), with a mean age of 55.9 years (range, 9-89). There were no significant differences in the demographics of the 2 subgroups. Complete resolution of symptoms was obtained in 81.3% of procedures without UBA and in 79.7% with UBA. Most patients (72.7%) were deemed idiopathic preoperatively. Lacrimal sac biopsy demonstrated significant pathologic factors in 9 (7.3%) cases, with 7 (5.7%) of these resulting in a new diagnosis for the patient. There were no cases of cerebrospinal fluid leakage, visual loss, diplopia, infection, or uncontrolled epistaxis in either group. CONCLUSIONS:: Early results of eDCR with UBA appear to show reasonable efficacy. The overall success and failure rates of eDCR with and without UBA are similar. Neither group had any complications in this study, although any conclusion on the overall safety of the procedure is limited by the power of this study.
