背景:鼻旁扩张术一直是恢复亚洲患者外侧轮廓的一种流行方法。手术区域的不规则表面强调了形态学证据对术前评估和鼻旁植入物设计的重要性。
方法:我们回顾性收集了2020年至2022年整形外科患者的颅面计算机断层扫描扫描。将成像数据导入Mimics(20.0版;物化,鲁汶,比利时)进行三维重建。在3-matic(版本12.0;Materialize)中进行了骨鼻基部的测量。鼻旁凹陷的严重程度由资深医生分级,以研究与测量变量的相关性。
结果:本研究纳入了57例中位年龄为27岁(IQR:22-33)的患者。对于鼻旁植入物的设计,测量下边缘和横向边缘的长度作为参考。在回归分析中,鼻翼底-肺泡突角与鼻旁凹陷程度显著相关(OR=1.222,p=0.00001)。
结论:在目前的研究中测量并呈现了骨鼻基部的形态学数据。分析支持将鼻翼底-肺泡过程角度用于术前分级和评估,以帮助指导治疗决策。

BACKGROUND: Paranasal augmentation has been a popular approach in restoring Asian patients\' lateral profile. Irregular surface in the surgical area emphasizes the importance of morphological evidence for the preoperative evaluation and the design of paranasal implants.
METHODS: We retrospectively collected craniofacial computer tomography scans of patients in the department of plastic surgery from 2020 to 2022. The imaging data were imported to Mimics (version 20.0; Materialize, Leuven, Belgium) for three-dimensional reconstruction. Measurements of osteal nasal base were performed in 3-matics (version 12.0; Materialize). The severity of paranasal concavity was graded by a senior doctor to study the correlation with measured variables.
RESULTS: Fifty-seven patients with a median age of 27 years (IQR: 22-33) were included in the study. For design of paranasal implants, the lengths of both lower and lateral edge were measured for reference. In the regression analysis, the alar base-alveolar process angle was significantly associated with the degrees of paranasal concavity (OR = 1.222, p = 0.00001).
CONCLUSIONS: Morphological data of osteal nasal base were measured and presented in the current study. The analysis supported that alar base-alveolar process angle be used for preoperative grading and evaluation to help guiding treatment decisions.
