The transverse myocutaneous gracilis free flap: a valuable tissue source in autologous breast reconstruction

The transverse myocutaneous gracilis free flap with a transverse orientation of the skin paddle in the proximal third of the medial thigh region allows the taking, in selected patients, of a moderate amount of tissue for autologous breast reconstruction. The donor-site morbidity is similar to that of a classic medial thigh lift. The indication for this flap in autologous breast reconstruction and the surgical technique will be discussed in this article. From August of 2002 to March of 2003, 10 patients underwent autologous breast reconstruction with 12 transverse myocutaneous gracilis free flaps. The patients' ages ranged from 26 to 48 years (median, 40 years). Of those, two BRCA-positive women received bilateral breast reconstructions after prophylactic skin-sparing mastectomy, and eight patients received immediate breast reconstruction after skin-sparing mastectomy in early-stage breast cancer. Mean follow-up of the 10 patients was 5 months (range, 1 to 9 months). We had no free-flap failure. Four patients had small areas of ischemic skin necrosis related to very thin preparation of the skin envelope after skin-sparing mastectomy without altering the final aesthetic results. Cosmetic evaluation of the reconstructed breasts and thigh donor site by two plastic surgeons showed good results in nine patients and fair results in one patient. There was no functional donor-site morbidity caused by harvesting the gracilis flap. The transverse myocutaneous gracilis flap is a valuable alternative for immediate autologous breast reconstruction after skin-sparing mastectomy in patients with small and medium-sized breasts and inadequate soft-tissue bulk at the lower abdomen and gluteal region.     

Latissimus dorsi myocutaneous flap for breast reconstruction: long-term results.

A review was performed on 170 patients who underwent 173 consecutive latissimus dorsi myocutaneous flap breast reconstructions between 1978 and 1989. The majority of the patients had modified radical mastectomies, and reconstruction was usually delayed for 3 to 18 months after mastectomy. Acceptable symmetry was obtained in the majority of patients without the need for surgery on the opposite breast. Perioperative and long-term complications are reviewed. Patients were followed for an average of 4.7 years after reconstruction. Ninety-four percent of patients demonstrated little or no change in the reconstructed breast after the first year. This method of reconstruction has met patient expectations with a minimum number of procedures and low morbidity.     

The extended vertical rectus abdominis myocutaneous flap for breast reconstruction

The extended vertical rectus abdominis myocutaneous flap has been used in 34 patients for breast reconstruction after radical mastectomy. This flap can reconstruct a large ptotic breast mound and fill the infraclavicular and axillary areas. The operative technique and a discussion of the method are presented. There are several advantages to the extended vertical rectus abdominis myocutaneous flap. First, the main advantage of this flap is its reliable vascular supply, which can reach to the infraclavicular and axillary areas. Second, the large volume of this flap can reconstruct the large ptotic breast, fill the infraclavicular hollow, and create an axillary fold. Third, no lower abdominal wall hernias have developed, and use of alloplastic abdominal wall reinforcement is not necessary. Finally, the simultaneous beneficial effect of horizontal abdominoplasty, which further enhances the patient's body image by narrowing the waist, is unique to this vertical abdominal flap. The disadvantages of this flap include (1) the midline abdominal scar, (2) an umbilical scar on the reconstructed breast, and (3) in principle, inappropriateness for the patient who desires pregnancy postoperatively.     

Double-pedicle transverse rectus abdominis myocutaneous flap for unilateral breast and chest-wall reconstruction

Fifteen patients underwent unilateral breast and chest-wall reconstruction by a double-pedicle transverse rectus abdominis myocutaneous flap technique. Criteria for using both pedicles include (1) exceptionally large soft-tissue requirements, (2) prior abdominal operations compromising the vasculature to portions of the anterior abdominal wall, and (3) certain higher-risk patients with suspected microvascular pathology. Double pedicles allowed the transfer of the skin island as one unit or as two independent hemiellipses of tissue. Follow-up time ranges from 4 to 17 months. Complications included partial tissue loss in two patients, one abdominal flap seroma, and one patient with a hernia.     

Pectoralis major myocutaneous flap for hypopharyngeal reconstruction

The reconstruction of total or subtotal defects after surgical treatment for hypopharyngeal cancer is a challenging problem in head and neck surgery. The authors discuss reconstructive surgery performed in 37 patients affected by advanced hypopharyngeal cancer using the pectoralis major myocutaneous flap. In 22 cases of total pharyngolaryngectomy, the reconstructive procedure originally proposed by the authors was based on the use of a pectoralis major myocutaneous flap directly sutured to the pharyngeal and esophageal stumps and the prevertebral fascia, which eventually represented the posterior wall of the neohypopharynx. In 15 cases of subtotal pharyngolaryngectomy, the posterior wall of the neohypopharynx consisted of a residual strip of pharyngeal mucosa. In each patient, removal of the tumor and reconstruction were performed during the same operation, with only a few complications. Neither flap necrosis nor strictures were encountered; five patients had pharyngeal fistula and one patient died because of massive pneumonia. Although the use of microvascular free flaps is a reliable procedure, the pectoralis major myocutaneous flap is still applicable for hypopharyngeal reconstruction, thanks to its feasibility and low complication rate. The other reconstructive options require surgical transgression of the abdomen and/or thorax in patients affected by malnutrition and other chronic systemic disorders.     

Reconstruction of the vulva with V-Y advanced myocutaneous gracilis flap

Reconstruction of the vulva with V-Y advanced triangular myocutaneous gracilis flap(s) is reported. Seven patients were treated with this technique following radical vulvectomy with two minimal complications. The reliability of this known flap and the usefulness of the V-Y advancement are stressed and make it a simple and successful technique.     

Refinements in transverse rectus abdominis myocutaneous flap breast reconstruction: projection and contour improvements

A surgical procedure with the transverse rectus abdominis myocutaneous (TRAM) flap for breast reconstruction is presented using parameters from the opposite normal breast to achieve a better cone shape in the new breast to project the nipple-areola complex. This cone projection is obtained through a vertical plication of both skin/fat halves of the TRAM flap and with two supraumbilical fat flaps to avoid cone collapse. The infraclavicular and axillary regions are filled with a de-epithelialized "fish-fin" cutaneous-fat or fat-only flap, which is placed as a lateral TRAM extension. The de-epithelialized lateral extremity of the TRAM flap folded over itself gives a mound shape to the lateral aspect of the new breast, and the inverted umbilical stalk attached to the TRAM flap imitates a nipple. This procedure is based on six breast reconstructions with a 2-year follow-up. The procedure is a simple, safe, and versatile way to mimic the opposite breast. It is mostly indicated for thin patients who have small to moderate breasts without ptosis or hypertrophy who refuse breast implants or request a mastopexy or reduction mammaplasty on the opposite normal breast during the same procedure.
