Sensitive areolar reconstruction in using a neurocutaneous island flap based on the medial antebrachial cutaneous nerve.

Sensory reconstruction has recently been stressed in breast reconstruction. However, there are no reports concerning the reconstruction of a sensitive areola. The bilateral reconstruction of a sensitive areola using a neurocutaneous flap based on the medial antebrachial cutaneous nerve is reported. The flap was harvested from the distal third of the forearm as an island flap and tunneled to reach the apex of the new breast, which was previously reconstructed using a 135-cc, gel-filled, silicone prosthesis covered by a latissimus dorsi myocutaneous flap. Six months later, fine sensibility in the reconstructed areola was demonstrated. The patient could perceive light touch, pain, and 14 mm two-point discrimination. At 2 months after surgery, 50 percent of cutaneous faulty stimulus location was observed. However, at 4 and 6 months after surgery, faulty location disappeared. Six months after harvesting the medial antebrachial cutaneous nerve, the sensory deficit was minimal; it included a hypoesthesic zone of 4 to 7 cm and an anesthesic zone of 2.5 to 5 cm on the middle third of the forearm. Fifteen months after the procedure, no hypoesthesic zone was observed; only a 2 to 3 cm anesthesic zone on the proximal medial side of the forearm existed. This sensory deficit passed unnoticed by the patient. The technique developed here is a refinement in breast reconstruction, and we think it should be used in selected patients.
