A systematic review and meta-analysis of capsular contracture rate after breast augmentation with textured and smooth breast prostheses

Background: With the development of breast augmentation and the increased people's pursuit of beauty, more and more women choose breast prosthesis breast augmentation. This study aimed to evaluate the incidence of capsular contracture after breast augmentation with textured and smooth breast prostheses by meta-analysis. Methods: Studies relating to capsular contracture after breast augmentation with textured breast prosthesis and smooth breast prosthesis were retrieved from the Chinese Journal Full-text Database (CNKI), VIP, the Wanfang Science and Technology Journal Full-text Database, the Chinese Biomedical Literature Search Database (CBM), PubMed, Embase, and the Cochrane Library. The search period was from database establishment to October 2021. EndNote X9 software (Clarivate, Philadelphia, PA, USA) was used to screen and exclude duplicate studies, screen the studies according to the inclusion and exclusion criteria, and extract data for quality evaluation. The data were recorded using the Stata 15.1 software (StataCorp LLC, College Station, TX, USA), and a meta-analysis was performed on the incidence of capsular contracture after breast augmentation with textured and smooth breast prostheses. Finally, the reliability of the results was assessed by sensitivity analysis. A funnel plot was used to evaluate the publication bias of the literature. Results: A total of 13 articles were included, and the total sample size of the study was 5,440. The results of the meta-analysis showed that the incidence of capsular contracture after breast augmentation with textured breast prostheses was significantly lower than that with smooth breast prostheses (OR =0.26; 95% CI: 0.08, 0.81; P<0.05). Discussion: The incidence of capsular contracture after breast augmentation with textured breast prosthesis is significantly lower than that with smooth breast prosthesis.
