In recent years, the perpendicular plate of the ethmoid (PPE) has emerged as a new autogenous grafting material in rhinoplasty and septoplasty of nasal deviation. However, no studies have outlined the precise size, shape, and morphologic features of the PPE. Therefore, this study aimed to provide detailed information on the anatomical and morphologic characteristics of the PPE to assist surgeons in performing surgeries that are more precise. About 104 Chinese patients who underwent paranasal computed tomography were assessed in this study. By analyzing the features of the PPE reconstructed with 3-dimensional models, the characteristics of the PPE at different stages of development and according to sex were observed. The PPE had a flat shape, and its lower part was relatively thin. It usually developed horizontally with age, which contributed to expansion of the PPE area. The dimensions of the PPE were significantly larger in male patients than in female patients. Through the reconstruction and measurement of Chinese patients' PPE, the authors have established precise information about the PPE's anatomical and morphologic features. The flat shape and proper size, which are similar to those of nasal septum cartilage, make the PPE an ideal alternative to conventional autogenous grafting materials. The findings might be useful to surgeons in helping them perform surgeries that are more precise.
近年来，筛骨垂直板（PPE）已成为鼻整形术和鼻中隔偏曲矫正术中一种新型的自体移植材料。然而，尚无研究明确阐述PPE的精确尺寸、形状和形态学特征。因此，本研究旨在提供有关PPE解剖学和形态学特征的详细信息，以协助外科医生进行更精确的手术。本研究评估了约104例接受鼻窦计算机断层扫描的中国患者。通过分析用三维模型重建的PPE的特征，观察了PPE在不同发育阶段以及根据性别划分的特征。PPE呈扁平状，其下部相对较薄。它通常随着年龄的增长而水平发育，这有助于PPE面积的扩大。男性患者的PPE尺寸明显大于女性患者。通过对中国患者PPE的重建和测量，作者建立了有关PPE解剖学和形态学特征的精确信息。PPE的扁平形状和合适尺寸与鼻中隔软骨相似，使其成为传统自体移植材料的理想替代品。这些发现可能有助于外科医生进行更精确的手术。
