Abstract Background: Breast cancer is the one of the important medical issues nowadays. The surgical treatment of breast cancer has evolved greatly over the past years. It has developed from a radical procedure to a procedure combining both oncologic and aesthetic principles. Upon well-understanding of the anatomy of the breast, surgeons could develop the oncoplastic procedures. Aim of Study: To assess, through the available literature, the oncologic and aesthetic outcomes of the Round Block Technique and to identify the post-operative complications after the use of this technique. Material and Methods: Publications from Medline data-bases (PubMed, Medscape, ScienceDirect. EMF-Portal) and all materials available on the Internet till 2021. This is a meta-analysis of the Round Block Technique in the surgical management for breast cancer. It was done from December 2020 till January 2022. This review was conducted according to the Preferred Reporting Items for Meta-Analyses (PRISMA) guidelines. 80 The PRISMA Statement was pub-lished in 2009. If the studies did not fulfill the inclusion criteria, they were excluded. Study quality assessment included whether ethical approval was gained, eligibility criteria spec-ified, appropriate controls, and adequate information and defined assessment measures. Results: As regards the total post-operative complications, they were low after the use of the Round Block Technique. It had a percentage of 17.2% (95% CI: 12.4-23.4%). Infection was reported in percentage of 4% (95% CI: 2.9%-5.5%), seroma had a percentage of 6.5% (95% CI: 3.7%-11.4%), hematoma had a percentage of 3.8% (95% CI: 2.6%-5.4%), wound complications had a percentage of 3.3% (95% CI: 2.2%-5.1%) while the Nipple-areola complex complications had a percentage of 2.4% (95% CI: 0.8&-6.9%). After all these results, it's obvious that the Round Block technique had a low rate of different types of post-operative complications. Conclusion: Round Block technique is an excellent choice as an oncoplastic technique in patients with early breast cancer with mild to moderate ptosis. It's safe oncologically with a very good aesthetic outcome. Patients underwent that technique had high satisfaction with a low rate of complications.
