The omnipotential pig buttock flap.
An experimental pig flap model is presented with detailed operative technique. Studies employing this model are reported showing that difference in survival patterns depends on vascular configuration. Innervated island flaps were found to survive to the same length as denervated free flaps, and the onset of the benefits of the delay procedure occurred by the fourth postoperative day. The advantages of the pig and the pig buttock flap are discussed in detail.
