Tissue expansion before microvascular free flap transfer creates large, thin flaps. This technique minimizes donor site deformity and allows safe suturing under tension for reconstructing large defects.

Area of Science:

  • Plastic Surgery
  • Reconstructive Surgery
  • Tissue Engineering

Background:

  • Microvascular free flap transfer is a reconstructive technique.
  • Tissue expanders have been used as an adjunct to free flap transfer.
  • The effect of pre-transfer flap expansion was investigated.

Observation:

  • Two case reports detail the use of expanded free flaps.
  • Expanded flaps were observed to be large and thin.
  • A capsule formed around the expanded flap.

Findings:

  • Expanded free flaps are large and thin, facilitating reconstruction.
  • The capsule allows for safe suturing under tension.
  • The expansion process "delays" the flap, reducing donor site deformity.

Implications:

  • Tissue expansion is a valuable pre-operative technique for free flap transfer.
  • This method is particularly useful for reconstructing large defects.
  • Expanded flaps offer advantages in terms of size, vascularity, and donor site morbidity.
