Comparison between rapid and slow tissue expansion in breast reconstruction

Area of Science:

• Plastic Surgery
• Biomaterials Science

Background:

• Tissue expanders are commonly used in breast reconstruction.
• Optimizing the tissue expansion process is crucial for aesthetic outcomes and patient satisfaction.
• Understanding the impact of expansion speed on long-term results is essential for surgical technique refinement.

Purpose of the Study:

• To compare the efficacy of rapid versus slow tissue expansion in breast reconstruction.
• To evaluate the long-term effects of expansion speed on capsular contraction and breast softness.
• To assess the correlation between subjective and objective methods for evaluating breast implant outcomes.

Main Methods:

• Randomized controlled trial involving 50 women undergoing breast reconstruction with tissue expanders.
• Two groups: rapid expansion (daily) and slow expansion (weekly).
• Evaluation using Breast Augmentation Classification (subjective) and applanation tonometry (objective) at 6 and 12 months post-implant placement.

Main Results:

• Capsular contraction rates after 1 year were 33.5% subjectively and 50.5% objectively across all patients.
• No statistically significant difference in capsular contraction between rapid (40% subjective, 60% objective) and slow (27% subjective, 41.5% objective) expansion groups.
• Results were stable from 6 to 12 months, and irradiated patients did not show poorer outcomes.

Conclusions:

• The speed of tissue expansion (rapid vs. slow) does not significantly impact capsular contraction rates or breast softness in the long term.
• Both subjective and objective evaluation methods are valuable for assessing breast reconstruction outcomes.
• The findings support the stability of results and suggest that expansion timing can be flexible.
