Comparison of Endoscopic and Open Surgery for Gynecomastia

12 juni 2026 bijgewerkt door: Antalya City Hospital

Prospective Comparative Evaluation of Different Surgical Techniques in the Treatment of Gynecomastia: A Multicenter Study

The goal of this observational study is to compare the clinical outcomes, safety, and patient satisfaction of endoscopic versus conventional open surgical techniques in adult male patients undergoing surgery for gynecomastia.

The main questions it aims to answer are:

  • Does endoscopic gynecomastia surgery provide better aesthetic outcomes and patient satisfaction compared with conventional open surgery?
  • Does endoscopic surgery reduce postoperative complications, sensory changes of the nipple-areola complex, and visible scarring compared with conventional open surgery?

Researchers will compare patients undergoing endoscopic nipple-areola complex-preserving mastectomy with patients undergoing conventional open nipple-areola complex-preserving mastectomy to evaluate differences in surgical outcomes, complications, cosmetic results, and quality of life.

Participants will:

  • Undergo gynecomastia surgery as part of their routine clinical care using either an endoscopic or conventional open technique.
  • Attend routine postoperative follow-up visits for up to 12 months.
  • Complete patient-reported outcome assessments, including pain and satisfaction questionnaires.
  • Undergo evaluation of scar quality, nipple-areola complex sensation, and postoperative complications during follow-up.

Studie Bevolking

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.

Beschrijving

Inclusion Criteria:

  • Male patients aged 18 to 60 years.
  • Clinically and/or ultrasonographically confirmed primary gynecomastia with palpable glandular tissue ≥2 cm.
  • Simon Grade II or Grade III gynecomastia.

  • Eligible for either endoscopic or conventional open nipple-areola complex-preserving mastectomy according to routine clinical practice.
  • Ability to provide written informed consent.
  • Willingness and ability to comply with the 12-month follow-up schedule.

Exclusion Criteria:

  • Secondary gynecomastia caused by endocrine disorders, medications, hypogonadism, thyroid disease, or suspected malignancy.
  • Pseudogynecomastia (lipomastia without glandular proliferation).
  • Age younger than 18 years or older than 60 years.
  • Severe uncontrolled comorbidities that may increase surgical risk.

Cohorten en interventies

Groep / Cohort
Interventie / Behandeling
Endoscopic NAC-Preserving Mastectomy Cohort
Adult male patients with gynecomastia undergoing endoscopic nipple-areola complex-preserving mastectomy as part of routine clinical care. Participants will be followed for 12 months to assess postoperative complications, nipple-areola complex sensation, scar quality, patient satisfaction, and quality of life.
The procedure is performed under general anesthesia using a minimally invasive endoscopic approach. Breast glandular tissue is removed through a small axillary incision while preserving the nipple-areola complex. Liposuction may be performed when clinically indicated. The surgical technique is performed as part of routine clinical care and is not assigned by the study.
Conventional Open NAC-Preserving Mastectomy Cohort
Adult male patients with gynecomastia undergoing conventional open nipple-areola complex-preserving mastectomy as part of routine clinical care. Participants will be followed for 12 months to assess postoperative complications, nipple-areola complex sensation, scar quality, patient satisfaction, and quality of life
The procedure is performed under general anesthesia using a conventional open surgical approach. Breast glandular tissue is removed through a periareolar incision while preserving the nipple-areola complex. Liposuction may be performed when clinically indicated. The surgical technique is performed as part of routine clinical care and is not assigned by the study.
