This study aimed to compare the therapeutic effects of biplane skin dilator implantation with those of conventional skin dilator implantation in auricular reconstruction. A total of 137 patients with microtia who met the inclusion criteria from January 2020 to April 2021 were retrospectively selected. Sixty-three patients comprised the control group and were implanted with a skin expander using the conventional method. Seventy-four patients comprised the experimental group and were implanted with a skin expander using the biplane method. Non-parametric tests were used to compare the down-moving distance of the skin dilator between the experimental group and the control group. There was a statistically significant difference in the down-moving distance of the skin dilator between the experimental group and the control group (P < 0.05). The chi-square test showed no significant difference in postoperative complications between the experimental group and the control group (P > 0.05). Moreover, there was no significant difference in the satisfaction rate of patients and their families between the experimental group and the control group (P > 0.05). In this study, the treatment effect of biplane skin dilator implantation was better than that of conventional skin dilator implantation.
本研究旨在比较双平面皮肤扩张器植入与传统皮肤扩张器植入在耳廓再造中的治疗效果。回顾性选择了 2020 年 1 月至 2021 年 4 月符合纳入标准的 137 名小耳畸形患者。其中 63 例患者为对照组，采用传统方法植入皮肤扩张器；74 例患者为实验组，采用双平面法植入皮肤扩张器。使用非参数检验比较实验组和对照组皮肤扩张器下移距离。实验组和对照组皮肤扩张器下移距离差异有统计学意义（P<0.05）。卡方检验显示实验组和对照组术后并发症无显著差异（P>0.05）。此外，实验组和对照组患者及其家属的满意度差异无统计学意义（P>0.05）。本研究表明，双平面皮肤扩张器植入的治疗效果优于传统皮肤扩张器植入。
