The Lateral Arm Flap
  FIG. 8-30. One-year follow-up shows good contour without breakdown. The patient has protective sensation and uses the hand with less pain.


A plastic surgical resident lost four fingers in a building collapse during an earthquake in Mexico City.

FIG. 8-31. A classical groin flap was used to close the initial wound. Later, a double toe transplant was performed to provide three finger "chuck-pinch."

FIG. 8-32. There was residual, painful scarring over the hypothenar area.

FIG. 8-33. A lateral arm flap was used to provide durable coverage over the ulnar base of the hand and expand the web space. (See Case 2, Chapter 28) Recipient area prepared.

FIG. 8-34. Final result. The flap sensory nerve was repaired to the dorsal ulnar sensory to provide protective sensation in this critical area.


A 67-year-old man was treated with radiation therapy after resection of a mandibular squamous tumor.

  FIG. 8-35. Mandibular nonunion, osteomyelitis, and an orocutaneous fistula developed. The segments were stabilized with a classical Roger Anderson external pins and bar.

FIG. 8-36. Wide debridement resulted in a soft tissue defect that included the floor of the mouth and the chin.

FIG. 8-37. A lateral arm flap was transected across its middle, using one paddle for the oral surface and the other paddle, folded, for the cutaneous surface.

FIG. 8-38. Late follow-up shows closure of the fistula, adequate skin cover, and lining. Mandibular nonunion went on to solid fusion.

FIG. 8-39. Intraoral view shows lining pad of the folded lateral arm flap.
