The muscle-sparing thoracotomy in infants and children.
Deformities of the chest wall, breast, shoulder girdle, and spine are well-documented sequelae of major thoracotomies that transect muscles, divide major motor nerves, resect ribs, or cause them to fuse. These deformities are probably aggravated by the growth process. This is why we make a plea for the routine use, in infants and children, of a muscle-sparing thoracotomy that will minimize these sequelae without sacrificing exposure. Major (lateral) thoracotomy by this technique involves these steps: (1) creating a transverse incision below the tip of the scapula, or a vertical axillary incision; (2) elevating the skin flaps to expose the muscles; (3) retracting the latissimus dorsi posteriorly; (4) retracting the serratus anterior and scapula superiorly; (5) disinserting the lower origins of the serratus if required only; (6) opening the desired intercostal space; (7) reapproximating the ribs without crowding, using a pericostal suture that is passed along the inferior rib subperiosteally, to avoid any compression on the neurovascular bundle; and (8) allowing the muscles to fall back into place, reattaching the serratus insertions as indicated. Lessened postoperative pain and improved respiratory function are additional benefits.
