Clinical Results of Nasopore; Nasal Packing on Endonasal Dacryocystorhinostomy

Purpose: To investigate the effects of Nasopore<sup>&#9415; as a nasal packing material on the surgical success rate and prevalence of postoperative complications after endonasal dacryocystorhinostomy (DCR). Methods: The present study included a total of 558 patients (699 eyes) with primary acquired nasolacrimal duct obstruction who underwent endonasal DCR; 227 eyes were packed with Nasopore<sup>&#9415; and 472 eyes were packed with Merocel<sup>&#9415;. The surgical success rate and postoperative complications such as synechiae, granulation, wound healing (osteal mucosal epithelium epithelialization), postoperative bleeding, infection, and revision rate were compared between the packing materials. Results: The surgical success rate of the Nasopore<sup>&#9415; group (99.1%, 98.6%) showed significantly better results than the Merocel<sup>&#9415;group (97.2%, 95.1%) at postoperative 1 and 3 months (p = 0.04, 0.03 Pearson chi-square test), whereas there was no statistically significant difference between the 2 groups in postoperative surgical success rate at 1 week and 6 months. In comparison of postoperative complications, the Nasopore<sup>&#9415; group (0%) showed a lower incidence of delayed wound healing (delayed epithelialization of osteal mucosal epithelium) than the Merocel<sup>&#9415; group (2.3%; p = 0.013), whereas there was no difference in granulation, synechiae, postoperative bleeding, infection and revision rate (p > 0.05). Conclusions: The Nasopore<sup>&#9415; group showed a lower proportion of delayed wound healing and improvement of the surgical success rate at an early postoperative period after endonasal DCR compared to non-absorbable nasal packing material.
