Abstract

Abstract: PURPOSE: To explore the surgical technique of modified Onizuka cheiloplasty for the changes of bilateral lip peak heights and evaluate the postoperative symmetry in a short time. METHODS: Charts of 19 unilateral cleft lip patients who were repaired by modified Onizuka in Shanghai Ninth People’s Hospital, Shanghai Jiao Tong University School of Medicine from September 2021 to December 2021 were retrospectively reviewed. The differences of bilateral lip peak heights immediately and one month after surgery and the changes of upper lip morphology were analyzed. The distance was measured by Adobe Photoshop CC software through photos. SPSS 25.0 software package was used for data analysis. RESULTS: The difference of lip peak height between the healthy side and the affected side was (0.40±0.35) mm and (0.53±0.40) mm immediately and 1 month after operation, respectively, there was no significant difference(P>0.05). It was found that the cupid’s bow was rebuilt in a natural form and the configuration of the upper lip was reconstructed symmetrically. The philtrum column was not disturbed by the small triangle flap. CONSLUSIONS: Modified Onizuka is an effective way for repairing unilateral cleft lip.
