摘要
To compare the extent of mucosal margins remaining unsutured at the end of ext ernal dacryocystorhinostomy (DCR) using single or double flap techniques and to evaluate the influence on outcome. Prospective, consecutive case series. The num ber and length of mucosal margins remaining unsutured at the end of external DCR were evaluated in 64 patients. Mucosal anastomosis was performed using either a conservative (group 1) or extended (group 2) double flap, or a single flap (gro up 3) dissection. Patients were selected for group 1 if the regional anatomy per mitted the desired dissection. All other patients were randomized to group 2 or 3. The mean length of unsutured mucosal margins was calculated for each group. S ubjects were followed up to 12 months, with final success rate recorded. In grou ps 1, 2, and 3 respectively: 11, 24 and 29 patients were recruited; four, 12, an d 10 mucosal margins remained unsutured; and the mean length of unsutured mucosa l margins was 16.36 mm (SD=2.8), 70.66 mm (SD=9.3), and 62.00 mm (SD=6.0). The m ean length of unsutured mucosal margins was significantly different, although gr oups 1 and 2 collectively did not have a significantly different mean length of unsutured mucosal margin from group 3. Mean follow up was 11 months (SD=2.2), 6 3 patients (98.43%) had a successful outcome with no significant difference amo ng groups (P=.429). Different patterns of mucosal dissection in external DCR cre ate a different number and extent of unsutured mucosal margins which do not appe ar to adversely affect the success rate of external DCR.
