Area of Science:

  • Anatomy
  • Plastic Surgery
  • Biomechanical Engineering

Background:

  • The inframammary crease is a critical aesthetic and functional landmark of the female breast.
  • Accurate anatomical understanding is essential for successful breast surgery, particularly augmentation and reconstruction.
  • Previous descriptions of the inframammary crease anatomy lack detailed focus on specific ligamentous structures.

Purpose of the Study:

  • To precisely define the anatomical components of the female inframammary crease.
  • To identify and characterize a specific ligament contributing to the inframammary fold.
  • To elucidate the clinical implications of this ligament in breast surgery outcomes.

Main Methods:

  • Performed thirteen blunt dissections of the female breast in cadavers.
  • Conducted one dissection in a living patient undergoing mastectomy.
  • Utilized histologic sections to confirm the origin of the identified ligament.
  • Examined the relationship of the ligament to transaxillary subpectoral mammaplasty techniques.

Main Results:

  • Identified a distinct ligament originating from the periosteum of the fifth rib (medially) and intercostal fascia (laterally).
  • Confirmed the ligament's insertion into the deep dermis of the inframammary skin fold.
  • Demonstrated that disruption of this ligament during dissection can cause the "double-bubble" phenomenon.
  • Established that the ligament's horizontal orientation influences breast ptosis and fall.

Conclusions:

  • The identified ligament is a crucial anatomical structure defining the inframammary crease.
  • Understanding and preserving this ligament is vital to prevent surgical complications like the "double-bubble" deformity.
  • The ligament's position is a determinant factor in breast shape and the management of breast ptosis.
