Abstract

Primary success rate of endonasal DCR has been reported as lower than that of the conventional procedure. Endonasal DCR has been performed from July 1991 to October 1994, with a follow-up period of 6 to 37.3months(mean, 14.2months). According to the period of the operation, 156 eyes of 132 patients were classified into three groups: Group 1;47 eyes between July 1991 and June 1992. Group 2;44 eyes between July 1992 and June 1993, and Group 3;65 eyes between July 1993 and October 1994. Success rates of the primary operation were 68.1% in Group 1, 84.1% in Group 2, and 92.3% in Group 3 respectively. The success rate of Group 3 reached almost similar to that of the conventional procedure. Improvement of success rate may be owing to appropriate preoperative evaluation, skillful surgical technique, and careful postoperative management.
