Comprehensive Comparison Between Shaped Versus Round Implants for Breast Reconstruction: A Systematic Review and...

Area of Science:

• Plastic Surgery
• Biomaterials Science
• Medical Device Evaluation

Background:

• Prosthetic breast reconstruction is increasingly popular, with diverse implant options available.
• Evaluating new shaped implants against conventional round implants is crucial for safety and efficacy.
• Limited research exists comparing shaped versus round breast implants for reconstruction outcomes.

Purpose of the Study:

• To conduct a meta-analysis comparing shaped and round breast implants in reconstruction.
• To evaluate complication profiles and aesthetic satisfaction between shaped and round implants.

Main Methods:

• Systematic literature search of PubMed/MEDLINE, Ovid, and Cochrane databases.
• Meta-analysis of 8 retrospective cohort studies (2490 cases).
• Calculated relative risks for infection, seroma, capsular contracture, rupture, rippling, failure, and implant removal; assessed aesthetic satisfaction.

Main Results:

• No significant differences in infection, seroma, capsular contracture, or reconstruction failure risks.
• Shaped implants showed significantly reduced risks of implant rupture and rippling.
• Subgroup analysis indicated higher infection risk with shaped/textured implants; other complications were similar.
• Aesthetic satisfaction scores were comparable between shaped and round implant groups.

Conclusions:

• Both shaped and round implants yield favorable breast reconstruction outcomes.
• Complication rates and aesthetic results are similarly low for both implant types.
• Shaped implants may offer advantages in reducing specific complications like rupture and rippling.
