To quantitatively measure the accuracy of preoperative computer imaging (PCI) as a reflection of postoperative rhinoplasty results.
Thirty-eight patients underwent primary and revision rhinoplasty. Six-month postoperative photographs and "morphed" PCI images were graded on a 5-point Likert scale by 2 panels of judges, one composed of surgeons and the other of nonsurgeons. Twelve parameters were assessed. Results were stratified based on primary vs revision rhinoplasty and degree of difficulty of the rhinoplasties. Patient surveys were conducted to determine correlation between satisfaction and PCI accuracy.
Mean overall accuracy was 2.98 by the expert panel, indicating moderate PCI accuracy. Supratip height was the lowest-rated parameter, while measurements of the upper third were most accurate. The accuracy in primary rhinoplasty was comparable to that found in revision surgery, although tougher cases were rated lower in overall accuracy and projection score. Satisfied patients had significantly higher PCI accuracy scores, and most patients found the PCI extremely useful.
Preoperative computer imaging is a useful exercise, valued by patients during the rhinoplasty consultation. Accuracy is moderate in both primary and revision cases, although supratip edema is a limiting factor at the 6-month mark.
定量测量术前计算机成像（PCI）作为鼻整形术后效果反映的准确性。
38例患者接受初次和修复性鼻整形手术。术后6个月的照片和“变形”的PCI图像由两组评委按照5分制李克特量表进行评分，一组由外科医生组成，另一组由非外科医生组成。评估了12个参数。结果根据初次与修复性鼻整形手术以及鼻整形手术的难度程度进行分层。进行患者调查以确定满意度与PCI准确性之间的相关性。
专家小组评定的平均总体准确性为2.98，表明PCI准确性中等。鼻尖上区高度是评分最低的参数，而鼻上部三分之一处的测量最为准确。初次鼻整形手术的准确性与修复手术相当，尽管难度较大的病例在总体准确性和突出度评分方面较低。满意的患者PCI准确性得分显著更高，并且大多数患者认为PCI非常有用。
术前计算机成像很有用处，在鼻整形咨询期间受到患者重视。初次和修复病例的准确性均为中等，尽管鼻尖上区水肿在6个月时是一个限制因素。
