Summary

Matrix rotation mammoplasty is an effective breast-conserving surgery for upper inner quadrant breast tumors. This technique preserves breast shape, with 88.6% of patients reporting satisfactory cosmetic results.

Area of Science:

  • Oncology
  • Plastic Surgery
  • Breast Surgery

Background:

  • Tumors in the upper/upper inner quadrant of the breast require careful management.
  • Wide excision for these tumors can negatively impact breast aesthetics.
  • Oncoplastic techniques aim to balance cancer removal with cosmetic outcomes.

Purpose of the Study:

  • To evaluate the efficacy and cosmetic results of matrix rotation mammoplasty for breast-conserving surgery.
  • To assess the impact of matrix rotation on breast shape and patient satisfaction.
  • To determine the suitability of this technique for tumors requiring wide excision.

Main Methods:

  • A cohort of 36 patients with upper/upper inner quadrant breast cancer underwent matrix rotation mammoplasty between June 2012 and April 2015.
  • Patients were divided into two groups: matrix rotation with periareolar de-epithelialization (donut group, n=11) and matrix rotation only (non-donut group, n=25).
  • Cosmetic outcomes were self-assessed via questionnaires, and follow-up included monitoring for local recurrence.

Main Results:

  • The average excised tumor weight was 104.1 g in the donut group and 84.5 g in the non-donut group.
  • 88.6% of patients (31/36) rated their postoperative results as acceptable or satisfactory.
  • 77.1% of patients (27/36) reported their treated breast appeared nearly identical or only slightly different from the untreated side.
  • One case of local recurrence was observed and managed with mastectomy and reconstruction.

Conclusions:

  • Matrix rotation mammoplasty is a straightforward breast-preserving technique for upper/upper inner quadrant breast cancers.
  • This method allows for wider tumor excision while maintaining acceptable breast appearance.
  • The technique offers a viable option for breast conservation without significant cosmetic compromise.
