Purpose
Traumatic nasolacrimal duct obstruction (NLDO) is commonly seen in patients with midfacial trauma. Patients with traumatic NLDO may experience epiphora, compromised visual acuity, and an increased risk of dacryocystitis. This study aimed to analyze the clinical profile and surgical outcome for dacryocystorhinostomy in patients with traumatic nasolacrimal duct obstruction (NLDO).
Methods
This is a single-center, retrospective study. We reviewed 46 patients (46 eyes) diagnosed with traumatic NLDO and treated with external or endoscopic dacryocystorhinostomy (DCR) between 2000 and 2018. Medical records regarding the demographics, clinical characteristics, surgical interventions, and surgical outcomes were reviewed. Univariable analysis and multivariable analysis for factors related to surgical outcome of DCR were conducted.
Results
A total of 46 patients (46 eyes) with traumatic NLDO receiving DCR were identified. The mean age was 33.3 years (range, 6－87 years). All patients received either external DCR (n = 39; 85 %) or endoscopic DCR (n = 7; 15 %). The total anatomical success rate was 93 % (n = 43) and the functional success rate was 77 % (n = 33). The mean follow-up duration was 17.1 months (range, 6-107 months). High velocity injury (n = 31, 67%), including blunt injuries in road traffic accidents, crush injuries by machines, and falls from high floors, was found to be the most common cause for traumatic NLDO. Stent migration (n = 5, 11%) was the most common complication after DCR. Le Fort III-II was found to be related to poor anatomical outcome after DCR in patients with traumatic NLDO.
Conclusion
Surgical outcome for DCR in traumatic NLDO was relatively poor in comparison with primary NLDO. Our results may assist in preoperative counseling and surgical planning for patients with traumatic NLDO.
