Temporoparietal-occipital flap for facial reconstruction

Eight patients with an extensive facial defect of the masseter region were reconstructed with a temporoparietal- occipital rotation flap. This flap is vascularized by both the arteria auricularis posterior and the arteria occipitalis lateralis. These vessels have been sufficient to ensure viability of the entire flap. It is elevated and easily transposed to the masseter region because of the distensibility obtained from the posterior neck. This approach avoided the need for an unsightly skin graft at the site while providing tissue with hair follicles that blend well with the surrounding hair. This large flap offers cosmetic advantages over other techniques for coverage of facial defects in men.     

The reverse auricular flap: a new flap for nose reconstruction.

In the present article, the authors describe a new chondrocutaneous island flap from the ear helix for nose reconstruction. Anatomic studies showed that helix vascularization depends mainly on the superficial temporal vessels. The presence of vascular communications between the anterior frontal branch of the superficial temporal system and the supraorbital and supratrochlear arterial systems allows this flap to be used in a reverse vascular flow fashion. This new flap has been used successfully in seven cases for reconstructing composite defects of the nasal tip and ala. The donor-site defect is repaired with an advancement and rotation flap from the helical rim, leaving an inconspicuous scar and giving an acceptable cosmetic result of the donor area.     

Conventional TRAM flap versus free microsurgical TRAM flap for immediate breast reconstruction

Immediate breast reconstruction using the transverse abdominal myocutaneous island (TRAM) flap was performed in 54 patients over the past 3 years at our institution. This represented approximately 59 percent of patients undergoing all types of immediate breast reconstruction. In 10 patients, the abdominal island flap was transferred as a free flap based on the deep inferior epigastric pedicle. These patients were compared with the other 44 patients, in whom the flap was transferred using the conventional technique. The TRAM flap is well suited for immediate breast reconstruction because the procedure can be carried out simultaneously with mastectomy using separate operating teams and instruments. The operation is safe and relatively free of complications. The free TRAM group compared favorably with the conventional group in terms of complications, operating time, estimated blood loss, hospitalization, and return to functional baseline. The free TRAM flap appears to be as safe as the conventional technique with the advantages of a more limited rectus muscle harvest, improved medial contour of the breast due to the lack of tunneling, and perhaps a healthier flap because of the large donor vessels.     

Innervated radial thenar flap combined with radial forearm flap transfer for thumb reconstruction

A radial thenar flap combined with radial forearm flap was used for the reconstruction of the ipsilateral thumb in four patients. Vascular supply of the combined flap was based on the radial artery and extending the vascular pedicle to the superficial palmar branch of the radial artery. The flap was sensated by the palmar branch of the superficial radial nerve. The size of the flap averaged 15 x 5 cm and the innervated region of the thenar eminence was an area approximately 5 x 3 cm located over the proximal parts of the abductor pollicis brevis and opponens pollicis muscles. The flap was transferred as a free flap in three patients and as an advancement flap in one patient. The flaps survived completely without complications. Satisfactory restoration of sensation was achieved in the flap area, as shown by 6 mm of average moving two-point discrimination. This combined flap may be a feasible reconstructive option for large palmar defects of the fingers such as degloving injuries.     

The elastic flap for lip repair

These cases illustrate a new concept in lip repair. This approach recognizes the great inherent elasticity of the oral cavity and takes advantage of the florid blood supply of the region. Recent laboratory studies of Taylor et al., as well as the works of Manchot and Salmon, are combined with anthropologic observations of tribal customs to formulate another way of looking at lip reconstruction. Triangularization of surgical defects, lip switching, and mobilization of distant flaps are avoided by taking advantage of stretched local tissues. Preoperative expansion is discussed as a future option.
