Abstract

Purpose : To evaluate the utility of a Nunchaku-style stents in various lacrimal surgeries.

Methods : Charts were reviewed for patients who underwent placement of the Nunchaku (FCI Ophthalmics, Pembroke, MA) stent placement between (2017-2018) an oculoplastic surgeon at a single institution. The primary outcome measures were recorded as the rate of resolution of daily epiphora or absence of daily tearing symptoms at the early (<30 days) and late post-operative visits (>30 days). Patient demographics, type of surgery, use of a lacrimal balloon dacryoplasty or canaliculoplasty, concomitant procedures, level of obstruction, size of tube and post-operative complications were recorded.

Results : 40 patients (51 eyes) were included. 27 underwent probing for congenital or acquired NLDO, 18 had dacryocystorhinostomy (DCR), 4 had canalicular laceration repair, and 2 had canalicular reconstruction following Mohs surgery. Rates of epiphora were evaluated at early (10.8 ± 8.13 days) and late (57.7 ± 50.41 days) post-operative timepoints. At early post-op follow-up 15 eyes (54.9%) of patients undergoing probing with silicone intubation had resolution compared to 17 eyes (94.4%) who underwent endoDCR. At late follow-up 24 eyes (88.9%) who underwent probing with silicone intubation had resolution compared to 17 eyes (94.4%) who underwent endoDCR. Eyes who received stents for canalicular reconstruction after Mohs or canalicular laceration repair didn’t exhibit occurrence of epiphora at any time points after surgery (table 1).

Conclusions : Traditionally Crawford style stents have been used in oculoplastic lacrimal surgery. The Nunchaku lacrimal stent - a self-retaining, push-style stent - circumvents the need for intranasal retrieval, securing, and is easier to remove. Overall, our results show that Nunchaku stenting with probing and endoDCR had high rates of success in the late post-operative period. In addition, low rates of new-onset epiphora after canalicular lacerations or canalicular repair after Mohs defects were seen. Higher rates of epiphora in the early post-operative period had improved at the later timepoints, which is likely attributable to post-operative swelling. This study provides further evidence that Nunchaku stents should be used with high confidence in treatment for patients with various lacrimal pathologies. Further studies directly comparing Nunchaku-style and Crawford tubes may be beneficial.
