PurposeWe report a simple and effective method of identifying the medial cut end of lower canalicular laceration cases.MethodsTwenty-seven eyes with lower canalicular lacerations as a result of trauma were involved in the study. Surgery was performed within 48 hours after injury for canalicular reconstruction. Upper canalicular probing was utilized to identify the medial cut end of deep canalicular lacerations when difficulties were encountered. Total time from the initiation of the probing procedure to the identification of the medial cut end of the lower canaliculus was measured.ResultsA total of 27 eyes with lower canalicular lacerations were reconstructed. In 20 eyes, the medial lacerated end was located by upper canalicular probing. The mean time from initiation of the probing procedure to identification of the medial cut end of the lacerated canaliculus was 2 minutes.ConclusionsWe conclude that upper canalicular probing in patients with lower canalicular lacerations significantly reduces the time from the initiation of the operation to the identification of the medial cut end of the lower canaliculus.

Purpose: This study evaluated the relationship of nasal cavity state and surgical results after endonasal dacryocystorhinostomy (DCR). Methods: We retrospectively analyzed 306 eyes of 204 patients between January 2007 and December 2011. The correlation between the existence of preoperative nasal cavity abnormality, postoperative nasal cavity complications after proper management of nasal cavity abnormality, and postoperative nasal cavity complications according to nasal packing material were investigated. We analyzed the success rates and the correlation between each set of factors. Results: The success rate of primary operations performed six months after tube removal was 87.3% (267/306). The success rate after secondary revision, granuloma removal and punctoplasty was 90.5% (277/306). Postoperative nasal cavity complications were inspected in 40 eyes. Of the 306 eyes, patients treated with Nasopore showed significantly more postoperative nasal cavity complications (47.8%, 32/67) than in patients treated with Merocel (3.3%, 8/239). The rate of postoperative nasal cavity complications was 8.7% in patients with normal nasal cavity, 16.7% in patients who received treatment, and 20% in patients without treatment, with significant statistical increase if the nasal cavity was abnormal (p = 0.019). The incidence of complications influenced the primary success rate (p = 0.008); however, preoperative nasal cavity abnormalities were not correlated with primary success (p = 0.479). Conclusions: In the case of endonasal DCR, preoperative nasal cavity abnormality and type of nasal packing material used did not affect the success rate but significantly affected postoperative nasal cavity complications. In conclusion, endonasal DCR with preoperative treatment of nasal cavity abnormality and Merocel packing is expected to reduce postoperative nasal cavity complications and increase patient satisfaction.
