Preoperative computer simulation (PCS) is a tool for demonstrating potential rhinoplasty results to patients and determining the patient's preferred external nasal appearance.
The authors evaluated the effectiveness of PCS in Asian rhinoplasty patients.
The records of 224 patients who underwent rhinoplasty were reviewed. Sixty-eight (30.4%) of these patients had received PCS. To evaluate the accuracy of PCS in predicting postoperative results, postoperative photographs and PCS images were graded on a 4-point scale by a panel of 3 otolaryngologists. Postoperative patient satisfaction was compared between the PCS and non-PCS groups. Aesthetic parameters were assessed in the PCS images to determine the patient's preferred external nasal appearance.
The mean overall accuracy of PCS was 86.0% according to the otolaryngologist panel's ratings: 41.2% of the surgical results were rated as identical, 44.1% as similar, 13.2% as approximate, and 1.5% as poor. There were no significant differences between the PCS and non-PCS groups in terms of patient satisfaction or revision rates (P > .05). The most favored nasal appearances were straight dorsum (63.2%), straight columella (50.0%), and convergent alar axis (64.7%). The mean (± standard deviation) preferred nasofrontal and nasolabial angles were 137.5° ± 6.9° and 97.3° ± 8.6°, respectively.
Preoperative computer simulation is an accurate tool for assessing preferred external nasal appearance and can be a reliable predictor of postoperative rhinoplasty results in Asian patients.
术前计算机模拟（PCS）是一种向患者展示隆鼻潜在效果并确定患者偏好的鼻外形的工具。
作者评估了PCS在亚洲隆鼻患者中的有效性。
回顾了224例行隆鼻手术患者的记录。其中68例（30.4%）患者接受了PCS。为评估PCS预测术后效果的准确性，由3名耳鼻喉科医生组成的小组对术后照片和PCS图像进行4分制评分。比较了PCS组和非PCS组患者术后的满意度。在PCS图像中评估美学参数以确定患者偏好的鼻外形。
根据耳鼻喉科医生小组的评分，PCS的平均总体准确率为86.0%：41.2%的手术结果被评为相同，44.1%为相似，13.2%为近似，1.5%为较差。PCS组和非PCS组在患者满意度或修复率方面无显著差异（P>.05）。最受欢迎的鼻外形是鼻背挺直（63.2%）、鼻小柱挺直（50.0%）和鼻翼轴汇聚（64.7%）。偏好的鼻额角和鼻唇角的平均（±标准差）分别为137.5°±6.9°和97.3°±8.6°。
术前计算机模拟是评估偏好的鼻外形的准确工具，并且可以作为亚洲患者隆鼻术后效果的可靠预测指标。
