Area of Science:

  • Plastic Surgery
  • Reconstructive Surgery
  • Breast Surgery

Background:

  • Reconstructed breasts often exhibit different ptosis resistance compared to natural contralateral breasts post-unilateral reconstruction.
  • Acellular dermal matrix (ADM) can reinforce the inferior pole of uplifted breasts during the incorporation phase.
  • Recurrent ptosis is a common concern following mastopexy procedures, particularly after breast reconstruction.

Purpose of the Study:

  • To evaluate the efficacy of incorporating acellular dermal matrix (ADM) slings in reducing recurrent ptosis after unilateral mastopexy.
  • To compare the rate of recurrent ptosis in patients who received mastopexy with ADM support versus standard mastopexy.

Main Methods:

  • A prospective randomized analysis of 24 patients with Grade III breast ptosis undergoing unilateral mastopexy.
  • Group A: Symmetrization mastopexy with an ADM sling to the inferior pole.
  • Group B: Standard symmetrization mastopexy without ADM support. Follow-up was conducted for 36 months.

Main Results:

  • A statistically significant difference (P < 0.05) in outcomes was observed between the groups over the 36-month follow-up.
  • From the sixth postoperative month onwards, Group A (with ADM) showed significantly less recurrent ptosis compared to Group B (P < 0.05).

Conclusions:

  • The addition of an acellular dermal matrix (ADM) sling provides an effective internal support layer.
  • ADM slings demonstrably delay the recurrence of ptosis, improving long-term results of mastopexy in reconstructed breasts.
