Charts of 120 patients who have undergone face lifts in a single practice have been reviewed for objective evidence of postoperative hematoma formation following traditional or second-look face lift surgery. The respective rates of hematoma formation-21.7 percent, as compared with 7 percent-were found to be significantly different (P less than 0.025) by chi-square analysis, and no extraneous factors can be asserted to explain this difference. The authors therefore conclude that the second-look technique is responsible for reducing postoperative complication from face lift and that it is a worthwhile modification to the traditional procedure.
对在同一医疗机构接受面部提升手术的120例患者的病历进行了回顾，以寻找传统或二次直视面部提升手术后血肿形成的客观证据。通过卡方分析发现，血肿形成的各自发生率分别为21.7%和7%，差异有统计学意义（P<0.025），且没有其他外在因素可以解释这种差异。因此，作者得出结论，二次直视技术有助于减少面部提升术后的并发症，是对传统手术的一项值得进行的改进。
