Summary
For breast reconstruction, round and anatomical implants show similar complication rates and aesthetic outcomes. Patient preference and surgeon expertise should guide implant choice for optimal results.
Area of Science:
- Plastic Surgery
- Oncological Reconstruction
Background:
- Implant-based breast reconstruction (IBBR) is a common oncological reconstruction method.
- Implants differ in size, composition, texture, and shape, with round and anatomical shapes being most prevalent.
- Previous studies explored differences in outcomes based on implant shape.
Purpose of the Study:
- To evaluate and compare postoperative outcomes and aesthetic satisfaction in IBBR using round versus anatomical implants.
- To conduct a systematic review and meta-analysis of comparative studies.
Main Methods:
- Systematic literature review and comparative meta-analysis.
- Included only comparative studies reporting postoperative complications or patient-reported outcomes.
- Calculated odds ratios and 95% confidence intervals using a random-effects model.
Main Results:
- Nine studies with 2535 patients (1578 round, 957 anatomical) were analyzed.
- No significant difference in overall complication rates between round and anatomical implants (OR=0.46; 95% CI=0.14-1.48; P=0.19).
- Specific complication rates and patient-reported outcomes were comparable across both implant groups.
Conclusions:
- Round and anatomical implants yield similar complication rates and aesthetic results in IBBR.
- Implant selection should involve shared decision-making, considering surgeon experience, patient morphology, and personal preference.
