The perpendicular plate of ethmoid (PPE) was used to correct short noses in rhinoplasty in Asians, but the safe harvest of the plate and the assessment of its clinical application has been perplexing to plastic surgeons.
To explore how to safely cut the perpendicular plate of ethmoid bone and evaluate its application effect.
PATIENTS/METHODS: A finite element model was established to guide the clinical operation. A total of 30 patients with short noses were selected. Among them, 15 patients used autologous septal cartilage to lengthen the nasal tip, and 15 patients used the PPE to strengthen the L-shape nasal septum. The differences in the esthetic parameters of the nose, complications, and patients' satisfaction were compared between the two groups.
Significant differences were noted in the nasal dorsal length (p = 0.001), Goode's ratio (p = 0.001), and nasofrontal angle (p = 0.003) after rhinoplasty, and no significant differences were noted in any of the esthetic parameters between the two groups. The symptoms of nasal obstruction in the experimental group were significantly lighter than those in the control group (p = 0.04). There was no statistically significant difference in the doctors' assessment of outcomes between the two groups (p = 0.48).
The safest region to harvest the PPE is in the middle and lower third. Rhinoplasty improves the esthetics of the patient's nose. The PPE used to strengthen the L-shape nasal septum structure has a smaller probability of nasal septal deviation with the time in Asian short noses.
在鼻整形术中，筛骨垂直板（PPE）被用于矫正亚洲人的短鼻，但如何安全地获取该板并评估其临床应用一直困扰着整形外科医生。
探索如何安全地切割筛骨垂直板，并评估其应用效果。
患者/方法：建立有限元模型以指导临床操作。共选择 30 例短鼻患者，其中 15 例患者采用自体鼻中隔软骨延长鼻尖，15 例患者采用 PPE 加强 L 形鼻中隔。比较两组患者的鼻部美学参数、并发症和患者满意度的差异。
两组患者的鼻部背侧长度（p=0.001）、Goode 比值（p=0.001）和鼻额角（p=0.003）差异有统计学意义，但两组患者的美学参数无统计学差异。实验组患者的鼻塞症状明显轻于对照组（p=0.04）。两组医生对手术结果的评估无统计学差异（p=0.48）。
PPE 最安全的采集区域位于中下段。鼻整形术可改善患者鼻部的美观。在亚洲短鼻中，用于加强 L 形鼻中隔结构的 PPE 发生鼻中隔偏曲的概率较小。
