Analysis of the Results Endonasal Dacryocystorhinostomy Related to Nasal Cavity State

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.

The Effect of Nasal Cavity Abnormality Related to Surgical Success Rate of Endonasal Dacryocystorhinostomy

PURPOSE: To investigate the effect of a nasal cavity abnormality on the success rate of endonasal dacryocystorhinostomy (DCR). METHODS: Two hundred seventy eyes of 230 patients who had undergone endonasal DCR from February 2003 to July 2004 were retrospectively analyzed. The patients were classified into three groups after all were preoperatively examined by an otolaryngologist. Group A consisted of patients who had no nasal cavity abnormality; Group B, patients who had a nasal cavity abnormality and who received treatment; and Group C, patients with a nasal cavity abnormality but who received no treatment. RESULTS: The success rate of endonasal DCR were 83.9% in Group A, 87.5% in Group B, and 79.2% in Group C, with no statistical significance among the three groups (p>0.05). CONCLUSIONS: The presence of a nasal cavity abnormality did not affect the success rate of endonasal DCR.
