title: Effects of nasopore packing on dacryocystorhinostomy.
abstract: OBJECTIVE
  To investigate the effects of placement of the absorbable packing material Nasopore at the anastomosis site of newly formed mucosal flaps on postoperative re-bleeding, discomfort, and on the success rate of dacryocystorhinostomy (DCR).
  
  
  METHODS
  A review of the medical records of patients with primary acquired nasolacrimal duct obstruction that underwent external or endonasal DCR by a single surgeon was performed. The degree of re-bleeding, discomfort, and postoperative results, including anatomical success, functional success and postoperative nasal findings such as granulation, synechiae, and membrane formation were compared in patients whose anastomosis site was packed with either Nasopore or Merocel, a non-absorbable packing material.
  
  
  RESULTS
  A total of 77 patients (101 eyes) were included. Of the 101 eyes, 30 were packed with Nasopore, while 71 were packed with Merocel. The Nasopore group showed significantly better results than the Merocel group in the degree of re-bleeding and the level of patient discomfort (p = 0.000, 0.039, respectively; Pearson's chi-square test), whereas there were no statistically significant differences between the two groups in postoperative anatomical and functional success (p > 0.05).
  
  
  CONCLUSIONS
  Nasopore significantly reduced postoperative nasal re-bleeding and patient discomfort during the early post-surgical period, but failed to show an effect on the postoperative anatomical and functional success of DCR.
