Analysis of risk factors affecting poor wound healing after primary cleft palate surgery.

Abstract

Objectives: To study the risk factors of poor wound healing after primary cleft palate surgery.

Methods: In this study, 980 cases of congenital cleft palate treated by Sommerlad-Furlow in the Department of Cleft Lip and Palate Surgery of Sichuan University from 2017 to 2021 were continuously analyzed. Indicators included patient's age, gender, body weight, cleft palate type, width of the widest fistula, cleft palate index (width of the widest fistula/width at the posterior edge of the maxillary tubercle plane), preoperative white blood cell count, preoperative hemoglobin level, preoperative antibiotic use, doctor's seniority, use of relaxation incision, operation time, postoperative upper respiratory tract infection, and postoperative wound healing. The postoperative wound healing was divided into normal healing, delayed healing, and palatal fistula. Both delayed healing and palatal fistula were classified as poor healing. The factors that may affect the healing outcome of the palatal wound after primary cleft palate repair were analyzed using SPSS 26.0 software.

Results: A total of 825 patients (84.2%) had normal healing, 112 patients (11.4%) had delayed hea-ling, and 43 patients (4.4%) had palatal fistula. Doctor's seniority, width of the widest fissure, cleft palate index, and operation time influenced the wound healing effect after cleft palate surgery (P<0.05). Doctors with low seniority, wide width of the widest fistula, large cleft palate index, and long operation time were the risk factors of poor wound healing.

Conclusions: Doctor's seniority, width of the widest fissure, cleft palate index, and operation time are related to the effect of healing effect after cleft palate surgery.
