Reconstruction of the nipple-areola complex.

We present a technique for nipple-areolar reconstruction, which consists basically of hinging two quadrangular dermafat flaps together after denuding the entire area. Mucosal grafts are then applied over the whole nipple-areolar site.     

Reconstruction of the burned nipple-areola complex

Reconstructive results of 115 burned nipple-areola complexes in 84 female patients were reviewed. Results of nipple reconstruction using local quadrapod flaps (33 percent good, 45 percent fair, 22 percent poor) and composition grafts from the earlobe (20 percent good, 60 percent fair, 20 percent poor) were comparable, and both were superior to results obtained with the "double-bubble" technique (24 percent good, 35 percent fair, 41 percent poor). Differences in nipple reconstruction techniques were not appreciated until 1 year postoperatively. The early appearance of areola reconstruction with tattooing and split-thickness grafts was excellent. However, significant late hypopigmentation changes were observed with both techniques. Areola reconstruction with full-thickness skin grafts from the superomedial thigh (47 percent good, 33 percent fair, 20 percent poor) were superior to those obtained with tattooing (14 percent good, 35 percent fair, 51 percent poor) and split-thickness skin grafts from the contralateral unburned areola (21 percent good, 21 percent fair, 58 percent poor). We recommend employing local quadrapod flaps (for nipple), provided there is adequate surrounding dermis, and full-thickness skin grafts (for areola) in the reconstruction of the burned breast.     

Appropriate location of the nipple-areola complex in males

Gynecomastia is a common deformity encountered by plastic surgeons. The appropriate location of the nipple-areola complex is a major determinant of the aesthetic success of the procedure.To study the natural location of the nipple-areola complex in the normally built male, 50 nonobese men with no evidence of gynecomastia and an average age of 27.9 years were examined.Three ratios were calculated and found to be relatively constant; they were the ratio between the height of the nipple and the height of the patient, the ratio between the distance between the nipples and chest circumference, and the ratio between the suprasternal notch-to-nipple distance and the height of the patient.Using these three parameters, a method of locating the nipple-areola complex on the male chest wall was devised. The method is advocated as a reliable, simple, and useful technique.     

The sensitivity of the nipple-areola complex: an anatomic study

Although preservation of the sensitivity of the nipple and areola is an important goal in breast surgery, only scant and contradictory information about the course and distribution of the supplying nerves is found in the literature. The existing controversy might be due to the difficulty in dissecting the thin nerves and to frequent anatomic variations that bias the results if only a small number of cadavers are dissected. We dissected 28 female cadavers and found that the nipple and areola were always innervated by the lateral and anterior cutaneous branches of the 3rd, 4th, and 5th intercostal nerves. The most constant innervation pattern was by the 4th lateral cutaneous branch (79 percent) and by the 3rd and 4th anterior cutaneous branches (57 percent). The anterior cutaneous branches took a superficial course within the subcutaneous tissue and terminated at the medial areolar border in all dissected breasts. The lateral cutaneous branches took a deep course within the pectoral fascia and reached the nipple from its posterior surface in 93 percent of the dissected breasts. In 7 percent of the dissected breasts, the lateral cutaneous branches took a superficial course within the subcutaneous fat and reached the nipple from the lateral side. These findings suggest that the nerves innervating the nipple and areola are best protected if resections at the base of the breast and skin incisions at the medial areolar border are avoided.     

Configuration and localization of the nipple-areola complex in men.

The causes of bilateral absence of the nipple-areola complex in men are seldom congenital, but attributable rather to destruction as a result of trauma, or after mastectomy in female-to-male transsexuals and in male breast cancer, or after the correction of extreme bilateral gynecomastia. Such a bilateral loss becomes a major reconstructive challenge with respect to the configuration and localization of a new nipple-areola complex. Because there is very little information available in the literature, we carried out a cross-sectional study on the configuration and localization of the nipple-areola complex in men.A total of 100 healthy men aged 20 to 36 years were examined under standardized conditions. The first part of the study dealt with the configuration of the nipple-areola complex (dimensions, round or oval shape). The second part concentrated on the localization of the complex on the thoracic wall with respect to anatomic landmarks and in correlation to various parameters such as weight and height of the body, circumference of the thorax, length of sternum, and position in the intercostal space.Of the 100 subjects examined, 91 had oval and seven had a round nipple-areola complex. An asymmetry between the right and the left side was found in two cases. The mean ratio of the horizontal/vertical diameter of an oval nipple-areola complex was 27:20 mm and the mean diameter for a round nipple-areola complex was 23 mm. The center of the nipple-areola complex was in the fourth intercostal space in 75 percent and in the fifth intercostal space in 23 percent of the subjects. To localize the nipple-areola complex on the thoracic wall de novo, at least two reproducible measurements proved to be necessary, composed of a horizontal line (distance from the midsternal line to the nipple = A) and a vertical line (distance from the sternal notch to the intersection of line A, = B). The closest correlation for the horizontal distance A was given by the circumference of the thorax: A = 2.4 cm + [0.09 x circumference of thorax (cm)], (r = 0.68). The best correlation to calculate the vertical distance B was found using the distance A and the length of the sternum: B = 1.2 cm + [0.28 x length of sternum (cm)] + [0.1 x circumference of thorax (cm)], (R = 0.50).In cases of bilateral absence, we recommend creating an oval nipple-areola complex in men. The appropriate localization can be calculated by means of two simple equations derived from the circumference of the thorax and the length of the sternum.     

Sensitivity of breasts reconstructed with the autologous latissimus dorsi flap

The purpose of this study was to measure, both objectively and subjectively, the sensitivity of breasts reconstructed with the autologous latissimus dorsi flap and to compare these results with those of other reconstruction techniques, especially the transverse rectus abdominis myocutaneous flap. The study population included 50 patients with autologous latissimus dorsi flap breast reconstruction; these patients had an average age of 51 years and an average follow-up of 27 months. Patients answered a seven-item questionnaire that attempted to define the sensitivity of the reconstructed and opposite breasts. This sensitivity was then measured objectively using standard techniques for heat, cold, and tactile sensations. After statistical analysis, these results were compared with those published for other reconstruction techniques. Overall results were comparable or superior to those published for other techniques for autologous breast reconstruction. A total of 56 percent of patients had fine or very fine sensitivity, but 70 percent deemed this sensitivity to be less than that of the opposite breast. A total of 94 percent of patients perceived the reconstructed breast as integral to their body image. The superior medial part of the breast had the greatest sensitivity, both objectively and subjectively. Autologous latissimus dorsi breast reconstruction, a good technique with excellent aesthetic results, affords satisfactory sensitivity. This is yet another advantage of the technique.
