Abstract:
This study aimed to analyze the anatomical differences in levator aponeurosis angle and length between both sides in double eyelidplasty in East Asians. The retrospective study included patients with mild blepharoptosis who underwent upper blepharoplasty with levator aponeurosis. In the study, 140 patients were enrolled, 126 females and 14 males, with an age range of 16-73 years. The mean levator aponeurosis angle was 19.2 ± 2.9° on the right and 17.0 ± 3.8° on the left, which was significantly different (95% CI, p < 0.001). The mean length was 24.1 mm on the right and 23.2 mm on the left, a difference that was also statistically significant (95% CI, p < 0.001). The relationship between the dominant eye and levator aponeurosis prominence was also investigated, although there was no apparent correlation. Within the limitations of the study, it seems that this is the first study of the anatomical differences of the levator aponeurosis between both sides, leading to a greater predictability of surgery to maximize postoperative symmetry.
摘要:
本研究旨在分析东亚人双眼皮成形术中两侧提上睑膜角度和长度的解剖学差异。这项回顾性研究包括轻度上睑下垂的患者,这些患者接受了上睑成形术并进行了提上睑膜成形术。在研究中,140名患者入选,126名女性和14名男性,年龄范围为16-73岁。左提肌肌腱膜平均角右侧为19.2±2.9°,左侧为17.0±3.8°,这是显著不同的(95%CI,p<0.001)。右侧平均长度为24.1毫米,左侧平均长度为23.2毫米,差异也有统计学意义(95%CI,p<0.001)。还研究了优势眼与提上膜膜突出之间的关系,虽然没有明显的相关性。在研究的局限性内,这似乎是对两侧提上肌肌腱膜解剖差异的首次研究,导致更大的手术可预测性,以最大限度地提高术后对称性。
