OBJECTIVE: To quantitatively measure the accuracy of preoperative computer imaging (PCI) as a reflection of postoperative rhinoplasty results. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.
