Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults over 18 scheduled for gender-affirming mastectomy or breast reconstruction.

Probably not a fit

Patients with pre-existing nerve conditions or those on medications affecting nerve regeneration may not benefit from this study.

What this trial studies

This observational study aims to assess postoperative sensation and patient-reported outcomes in individuals undergoing gender-affirming mastectomy and breast reconstruction. It compares patients who receive advanced surgical reinnervation techniques to those who do not, focusing on the impact of these techniques on sensation and satisfaction. The study employs quantitative sensory testing to measure various aspects of sensation, addressing limitations in previous research. By utilizing a standardized approach, the study seeks to provide comprehensive insights into the effectiveness of nerve preservation and grafting during mastectomy procedures.

Why it matters

Potential benefit: If successful, this study could lead to improved postoperative sensation and satisfaction for patients undergoing mastectomy.

How similar studies have gone: Previous studies have shown positive outcomes with similar reinnervation techniques, indicating potential for success in this approach.
