Purpose: Data supporting treatment recommendations for congenital nasolacrimal duct obstruction (CNLDO) in patients with craniofacial abnormalities is scarce. This study reports the incidence, clinical features, and outcomes of patients with concomitant craniofacial abnormalities and CNLDO., Methods: This multi-center, retrospective, population-based cohort study included all patients diagnosed with CNLDO before age 6 during a 10-year period in a single US county., Results: Of the 17,713 live births during the study period, 1998 infants were diagnosed with CNLDO, among whom 41 (2.05%) had associated congenital craniofacial abnormalities, yielding a birth prevalence of 23.1 (95% CI 16.6-31.4) per 10,000 live births. Craniofacial patients were significantly older at time of diagnosis (6.2 months) compared to uncomplicated CNLDO (3.7 months; p  = 0.035). There was no significant difference in mean age at spontaneous CNLDO resolution, but 31.7% of craniofacial patients required probing for CNLDO resolution, compared to 14.5% in the CNLDO group (OR 2.76 [95%CI 1.41-5.39] p  = 0.003). All but two patients with craniofacial abnormalities had resolution of symptoms after initial probing. Intraoperative probing findings indicated that 8 of 13 craniofacial patients had complex obstructions., Conclusions: The similar age at spontaneous resolution indicates that watchful waiting until approximately one year of age is a reasonable approach even in patients with craniofacial abnormalities, though more of these patients may require surgical intervention.

Purpose: Endoscopic surgeries, such as dacryocystorhinostomy (DCR), are increasingly performed for orbital and lacrimal conditions. This study describes and compares recent trends in endoscopic DCR with open, or external, DCR in the United States (US). Methods: Medicare-Part-B National Summary data files were analyzed from 2000 to 2015 for temporal and geographic trends in endoscopic and external DCR. Medicare Physician and Other Supplier public use files detailing provider information were collected and analyzed from 2012 to 2015. Results: Between 2000 and 2015, the number of external DCRs remained relatively unchanged (8008 to 7086, −0.7% average annual growth), while the number of endoscopic DCRs steadily increased (881 to 1674, 4.6% average annual growth). The greatest number of endoscopic DCRs were performed in the South Atlantic region, whereas the Mountain region had the greatest number per capita. From 2000 to 2015, the average payment per procedure for external DCR was $526.63, compared with $512.45 for endoscopic DCR. Of endoscopic DCRs performed from 2012 to 2015, 831 (79%) were performed by Ophthalmology, 184 (18%) were performed by Otolaryngology, and the remainder by other subspecialties. Conclusions: The number of endoscopic DCR surgeries increased over the last 15 years while the number of external DCR surgeries remained stable and continued to surpass endoscopic procedures. While ophthalmologists perform the overwhelming majority of endoscopic DCR, otolaryngologists are performing a growing number. [ABSTRACT FROM AUTHOR]
