Summary

This study compares two surgical methods for treating gynecomastia (enlarged male breast tissue): a newer endoscopic technique using small incisions versus traditional open surgery. Researchers will follow 100 men aged 18 to 60 for up to 12 months after surgery to see which method leads to better cosmetic results, fewer complications, and higher patient satisfaction.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

What this could lead to
If successful, this could show that a less invasive surgical technique provides better cosmetic results and fewer complications for men with gynecomastia.
What could go wrong
This is an observational study, not a randomized trial, so results may be influenced by patient selection. The study is also relatively small (100 participants), which limits how broadly the findings can be applied.

Who is studied

The study population consists of adult male patients with primary gynecomastia (Simon Grade II-III) who undergo surgical treatment at Antalya City Hospital and Istanbul Bagcilar Training and Research Hospital. Participants will undergo either endoscopic or conventional open nipple-areola complex-preserving mastectomy as part of routine clinical care and will be followed for 12 months to evaluate clinical outcomes, complications, aesthetic results, sensory outcomes, patient satisfaction, and quality of life.
