To assess the aesthetic and functional results of primary treatment of telecanthus in patients with naso-orbito-ethmoidal fractures, the results in 36 patients were evaluated in a retrospective study. Twenty had double-sided telecanthus: 13 required an indirect technique of canthopexy and seven a direct technique. Sixteen had unilateral telecanthus, of whom six were treated by the indirect and 10 by the direct technique. The intercanthal distance (ICD) was measured directly postoperatively and more than 12 months after reconstruction. The late ICD after application of the direct technique was nearly 3 mm smaller (ANOVA, P < or = 0.02, mean 34.3 mm) and yielded 2 mm less relapse (ANOVA, P < or = 0.02) as compared with the indirect technique. Delayed or late-primary treatment showed a significantly higher frequency of epiphora (chi-square test, P < or = 0.05). Early primary treatment of traumatic telecanthus produced the best aesthetic and functional result.
为评估鼻眶筛骨折患者内眦间距增宽一期治疗的美学和功能效果，我们进行了一项回顾性研究，评估了36例患者的治疗结果。20例为双侧内眦间距增宽：13例需要间接眦固定术，7例需要直接技术。16例为单侧内眦间距增宽，其中6例采用间接技术治疗，10例采用直接技术治疗。术后直接测量内眦间距（ICD），并在重建后12个月以上再次测量。与间接技术相比，应用直接技术后的晚期ICD小近3mm（方差分析，P≤0.02，平均34.3mm），复发少2mm（方差分析，P≤0.02）。延迟或二期初次治疗溢泪发生率显著更高（卡方检验，P≤0.05）。创伤性内眦间距增宽的早期一期治疗产生了最佳的美学和功能效果。
