Inferior Gluteal Artery Perforator Flap in Breast Reconstruction
- 57 Downloads
For reconstructing moderate-to-high projection breasts in nulliparous patients with insufficient abdominal tissue or prior abdominal surgeries, a unilateral inferior gluteal artery perforator (IGAP) flap is an alternative procedure. In patients with slim hips, however, unilateral gluteal tissue is insufficient and inferior gluteal crease displacement may develop postoperatively. Donor-site asymmetry is also a major disadvantage. Use of bilateral IGAP flaps for breast reconstruction helps to avoid asymmetry of the inferior buttock volume and shape. Bilateral flaps provide sufficient tissue volume and allow for reconstruction of a breast comparable to the unaffected side.
