The postoperative evaluation of cleft lip is an important means to improve the operation method and the effect of the restoration. In recent years, the methods of cleft lip repair, such as Chinese western rotary propulsion, reconstruction of labial and nasal muscle tension band+trefoil flap, etc., have been developed. However, at present, there are still many secondary deformities, such as obvious scars and alar collapse. In this paper, in a review of the previous literature, the existing methods, advantages and disadvantages, and the application of the evaluation of the postoperative effect of cleft lip were reviewed. To date, there are many methods that can be used to evaluate the effect of cleft lip surgery. These research methods can be divided into subjective evaluation and objective evaluation, such as subjective evaluation, direct measurement, photo measurement, and three-dimensional scanning measurement. Among them, the subjective evaluation is simple, but the reliability is poor, and this method is suitable for all patients with cleft lip. The direct measurement has a low cost and is only suitable for one-dimensional information measurement, but the accuracy is poor, so it is difficult to determine the endpoints. The time of the photo measurement method is short, which can avoid tissue deformation, but it is easy to produce errors; this method is suitable for patients with cleft lip who can cooperate. The three-dimensional scanning measurement has a high accuracy, is time consuming and is a simple method but has a high cost and is suitable for areas with appropriate equipment conditions. Overall, the evaluation of the postoperative effect of cleft lip surgery should combine subjective evaluation with objective evaluation, dynamic evaluation with static evaluation, and utilize long-term follow-up to obtain comprehensive and accurate information and provide a reference for clinicians to carry out cleft lip surgery.
