Purpose:
In recent years, 3D printing technology has been employed as a production method that builds materials layer upon layer, providing notable advantages in terms of individual customization and production efficiency. Autologous costal cartilage ear reconstruction has seen substantial changes due to 3D printing technology. In this context, this research evaluated the prospects and applications of 3D printing in ear reconstruction education, preoperative planning and simulation, the production of intraoperative guide plates, and other related areas.
Methodology:
All articles eligible for consideration were sourced through a comprehensive search of PubMed, the Cochrane Library, EMBASE, and Web of Science from inception to May 22, 2023. Two reviewers extracted data on the manufacturing process and interventions. The Cochrane risk of bias tool and Newcastle-Ottawa scale were used to assess the quality of the research. Database searching yielded 283 records, of which 24 articles were selected for qualitative analysis.
Results:
The utilization of 3D printing is becoming increasingly widespread in autogenous costal cartilage ear reconstruction, from education to the application of preoperative design and intraoperative guide plates production, possessing a substantial influence on surgical training, the enhancement of surgical effects, complications reduction, and so forth.
Conclusion:
This study sought to determine the application value and further development potential of 3D printing in autologous costal cartilage ear reconstruction. However, there is a lack of conclusive evidence on its effectiveness when compared to conventional strategies because of the limited number of cohort studies and randomized controlled trials. Simultaneously, the evaluation of the effect lacks objective and quantitative evaluation criteria, with most of them being emotional sentiments and ratings, making it difficult to execute a quantitative synthetic analysis. It is hoped that more large-scale comparative studies will be undertaken, and an objective and standard effect evaluation system will be implemented in the future.
