Heavy pendulous breasts cause physical and psychological trauma. Postburn deformity of breasts results in significant asymmetry, displacement of nipple-areola complex, due to burn scar contracture, and significant scarring; these factors add more psychological discomfort and subsequent behavioral changes. The use of the inferior pedicle procedure in burned breasts can solve many problems. The technique reduces the size of the large breast, eliminates the scar tissue by excising both medial and lateral flaps, and brings the mal-located nipple and areola to a normal position. This study stresses the possibility of harvesting the inferior dermal pedicle flap from within the postburn scar tissue without necrosis of the nipple and areola, because of the excellent flap circulation. Acceptable aesthetic appearance and retainment of nipple viability and sensitivity can be achieved with the inferior pedicle technique even with postburn deformity of the breast. The study was conducted on 11 women, all of whom had sustained deep thermal burns to the breasts and anterior torso and whose breasts were hypertrophied and pendulous.  相似文献

In reduction mammaplasty by the inferior pedicle technique, the dermal-breast pedicle can be manipulated to form a central breast mound and enhance breast projection. When this technique is applied both to macromastia and breast asymmetry, excellent early results are reported. To study the effects of time on breast reduction, 22 patients were followed for an average of 4.7 years. Contour of the breast mound and projection are well preserved. However, evaluation of long-term results reveals a gradual increase in the inframammary fold to inferior areola distance. Since no increase in the midclavicle to nipple distance is observed, inferior migration of the breast parenchyma and superior displacement of the nipple-areola with respect to the breast mound occur after reduction mammaplasty with the inferior pedicle technique.  相似文献

The aim of the present study was to evaluate the alterations of symptoms and tactile sensibility of the breast after reduction mammaplasty. In a prospective study, 10 women were operated on using the inferior pedicle technique. The patients were examined and interviewed preoperatively and at 2 weeks and 3 and 12 months postoperatively. Tactile sensibility was assessed by Somedic monofilaments applied on nine points on each breast: the nipple, four points on the areola, and in four quadrants of the skin. Preoperative tactile sensibility was compared with tactile sensibility in 10 normal controls. A median of 744 g of tissue was removed. All patients reported relief of shoulder and neck discomfort and improvement of skin sensibility 1 year after the operation. Two weeks after the operation, the sensibility of the areola was reduced (p < 0.05), but the skin sensibility of two quadrants was improved (p < 0.05). The sensibility of the areola was restored to preoperative values during the observation period. At 12 months, sensibility was improved compared with preoperative values both in the upper part of the areola and in three quadrants of the skin (p < 0.05). Significant improvement of skin sensibility was found between 3 and 12 months postoperatively in two quadrants of the breast. Also, the erectile function of the nipple was not altered by the operation. In conclusion, the sensibility of the breast was improved or unchanged 1 year after reduction mammaplasty using the Robbins technique. Continuous improvement of sensibility was found during the 1-year observation period. The evidence provided by this prospective study rules out the common misconception that a reduction mammaplasty gives the patient reduced areola sensibility and altered erectile function.  相似文献

Patients with macromastia often comment on a lack of sensation in their nipple-areola complex. A study was designed to investigate the cause of this decreased sensation. Two hypotheses were proposed. First, the decreased sensation could result from neuropraxia of the sensory nerve fibers secondary to traction caused by the heavy breast parenchyma. The second hypothesis proposed that tissue expansion of the nipple and areola by the voluminous breast parenchyma caused a decrease in nerve fibers per surface area and hence decreased sensory perception. Sixty-one patients were assessed in the study. All patients underwent surgery in which histological biopsy of either the areola alone (31 reduction mammaplasty patients) or the nipple and areola (30 mastectomy patients) was possible. Before surgery, each nipple-areola complex was tested with Weinstein Enhanced Sensory Test monofilaments as a quantitative test of tactile sensation. Breast cup size, ptosis, and weight of tissue excised were recorded to allow general assessment of the breast size. The nipple and areola biopsy specimens were assessed using immunohistochemistry (S-100 polyclonal antibody, Dako Z311) to measure nerve fiber count per unit area. Statistical analysis was undertaken to find any association among sensitivity, breast cup size, ptosis, weight of tissue resected, and nerve fiber density in the nipple and areola biopsy specimens. Sensitivity at the areola decreased with increasing breast cup size (r = 0.47, p < 0.001) and ptosis (r = 0.42, p = 0.002 for increasing distance between inframammary crease and nipple; r = 0.49, p < 0.001 for increasing manubrium to nipple distance). There was a weak correlation between nerve fiber density at the areola and breast cup size (r = -0.22, p = 0.1). Sensitivity at the nipple was higher than at the areola. Nerve fiber density count at the nipple was higher than at the areola, but there was no statistically significant correlation between nipple sensitivity and breast cup size, ptosis, or weight of tissue resected. The results suggest that the areola and nipple are different in their neuroanatomy. The areola is a thin, pliable structure that is predisposed to stretch as the breast enlarges and therefore experience a decrease in nerve fiber density. The nipple is a compact structure that is less likely to stretch with breast enlargement. In the nipple, neither sensory perception nor nerve fiber density varied with size or breast ptosis. The perceived lack of sensation in the nipple-areola complex is multifactorial. This study shows that neither traction injury to the sensory nerves nor decreased nerve density alone can explain the subjective numbness reported by patients with macromastia. Psychological factors, such as dissatisfaction with body form or interpretation of lack of sensation in the areola as also affecting the nipple, may influence the patient's assessment of the nipple-areola sensitivity.  相似文献

A method of breast reduction is presented that maintains the blood supply and innervation to the nipple and areola complex by means of an inferior pedicle, reduces the breast volume by removing tissue from the periphery of the breast, maintains breast shape with internal plication sutures, and limits the scar using a periareolar technique with a short inferior vertical-to-oblique extension. There were 167 breasts in 98 patients reduced in this fashion. The average resection volume was 632 g per breast, with an average follow-up of 7.6 months. The complication rate was similar to that observed using traditional inferior pedicle techniques with the inverted-T cutaneous scar. This technique has proven to be versatile, technically straightforward, and applicable to breasts of all sizes for both breast reduction and mastopexy. By combining the aesthetic advantage of less cutaneous scarring with the safety and familiarity of the inferiorly based pedicle, superior results in breast reduction can be obtained that are consistent, long-lasting, and satisfying for both patient and surgeon alike.  相似文献

A method that minimizes residual scarring following Poland's syndrome correction by latissimus dorsi muscle transposition and placement of a submuscular breast implant is described. In order to reduce any resulting unsightly scarring and, in particular, eliminate the anterior thoracic scar, both a dorsal S-shape and an axillary incision were made and the muscle flap was raised. A prosthesis was then inserted and the muscle flap sutured to the anterior chest wall through an anterior incision symmetrical to the inferior border of the contralateral areola. The latter is a previously undescribed approach that produces good cosmetic results.  相似文献

A personal technique for breast reduction utilizing a circular dermal-breast pedicle is presented. After a cutaneous glandular excision in the inferior pole and glandular excision in a discoid shape under the central area, the pedicle is folded on itself to produce a direct elevation of the nipple-areola complex into its new position, to enhance projection, and to act as a central support. A rational economy of scars is obtained by a central convergence of the breast tissue that stretches the breast periphery and by sutures finishing in the inferoareolar area. There the skin excess is removed to avoid scar lengthening in both the caudal and cranial directions. Evaluation of long-term results reveals maintenance of breast projection, preservation of the inframammary fold to inferior areola distance, and minimal residual scarring.  相似文献

The preservation of the sensitivity of the nipple-areola complex after reduction mammaplasty is an important goal. The authors performed this prospective study to accurately assess whether sensitivity changes are influenced by the weight of resection or the surgical technique. Eighty patients who underwent bilateral breast reduction (Lassus, 10 patients; Lejour, 13 patients; McKissock, 18 patients; Wuringer, 20 patients; and Georgiade, 19 patients) were tested for sensitivity changes of the nipple and cardinal points of the areola with Semmes-Weinstein monofilaments before surgery, at 3 weeks, and at 3, 6, and 12 months after surgery. Patient characteristics (age, body mass index, and preoperative sensitivity) were statistically similar in all groups. The mean resection weight was significantly smaller in the Lassus (540 g) and the Lejour groups (390 g) than in the Georgiade group (935 g). The sensitivity of the nipple and the inferior and lateral part of the areola was significantly lower after a superior pedicle technique (Lassus and Lejour) than after any other technique at 3 weeks and at 3, 6, and 12 months postoperatively. Insensate nipples and areolas were found only after breast reductions with the Lassus and the Lejour techniques (47.8 percent). Nipple sensitivity after breast reduction by the other techniques was unchanged (Wuringer, McKissock, and Georgiade) or sometimes even improved (Georgiade) as early as 3 weeks postoperatively. Changes in nipple and areola sensitivity after reduction mammaplasty depend on the surgical technique rather than the weight of resection. Superior glandular pedicle techniques that require tissue resections at the base of the breast are associated with a higher risk of injury to the nerve branches innervating the nipple-areola complex.  相似文献

The levels of the bacterial contamination of the nipple, the areola and the surrounding skin, the occurrence and species composition of staphylococci in 120 nursing women on days 4-5 after parturition have been studied. S. aureus contaminate the surface of the nipple and the areola in 75% of the examined women, and in 57.5% of these women the massive contamination of the above-mentioned areas (greater than or equal to 10(3) colony-forming units per sq. cm) is observed. In 80% of puerperae the occurrence of S. epidermidis on the nipple, the areola and the surrounding skin has proved to be practically the same. The population of S. aureus colonizing the mammary glands consists mainly of hospital strains; of these, 75.97% belong to phage type 75.  相似文献

The tuberous breast deformity is a rare entity affecting young women bilaterally or unilaterally. The deformity is characterized by a constricting ring at the base of the breast, which leads to deficient horizontal and vertical development of the breast with or without herniation of the breast parenchyma toward the nipple-areola complex and areola enlargement. Several methods have been put forward to correct the deformity, but most of these fail to address the issue of the constricting ring and subsequently yield results that are not aesthetically satisfactory. A new approach to the treatment of the deformity is presented, which consists of a periareolar approach and rearrangement of the inferior part of the breast parenchyma by division of the constricting ring, thus creating two breast pillars. These pillars are allowed to redrape, and in cases of volume deficiency, a silicone breast implant is placed in a subglandular pocket. The procedure is completed by a donut-type excision to address the size of the nipple-areola complex. The technique has used on 11 patients (21 breasts) with excellent aesthetic results.  相似文献

Breast sensitivity after vertical mammaplasty   总被引:7,自引:0,他引:7  
Breast sensation after reduction mammaplasty is a major concern for surgeons and patients. The sensitivity of 80 breasts that were reduced using Lejour's technique (a superior dermoglandular pedicle with resection at the lower quadrants) was assessed in a prospective study. Ten points were selected on each breast for this study, including the nipple, four points on the areola, and five points on the breast skin. The measurements were performed preoperatively and at 3, 6, and 12 months postoperatively. Pressure thresholds were measured with 20 Semmes-Weinstein monofilaments, temperature sensitivity with hot and cold metal probes, vibratory thresholds with the Biotesiometer, and static and moving two-point discrimination tests with a Disk-Criminator. To assess the influence of breast ptosis and hypertrophy on sensitivity, the population was divided into two groups. In group I (19 patients), the sternal notch-to-nipple distance was less than 29 cm, and less than 500 g of tissue per breast was removed. In group II (21 patients), the sternal notch-to-nipple distance was more than 29 cm, and more than 500 g of tissue was resected. The sensitivity on the nipple and areola was significantly decreased at 3 and 6 months postoperatively for all modalities. At 1 year, sensitivity recovered, and no breast or nipple-areola complex was insensitive. Pressure sensitivity was not significantly different from the preoperative measurement in any area of the breast or in either group of patients, except for superior breast skin, for which sensitivity was improved in group II (p = 0.0004). Temperature sensitivity in group I was not different preoperatively and postoperatively, but in group II, a significant decrease was observed in sensitivity for the nipple and areola (p = 0.01 and 0.004, respectively). Vibratory sensitivity was significantly decreased on the nipple, the areola, and the inferior breast skin (p = 0.01, 0.01, and 0.001, respectively) in group II but not in group I.In conclusion, ptotic or moderately hypertrophied breasts that were reduced using Lejour's technique recovered their preoperative level of sensitivity after an initial postoperative decline. However, in large breasts, although pressure sensitivity recovered after 1 year, temperature and vibration sensitivity remained diminished on the nipple-areola complex.  相似文献

Assessment of long-term nipple projection: a comparison of three techniques   总被引:4,自引:0,他引:4  
Nipple-areola reconstruction represents the final stage of breast reconstruction, whereby a reconstructed breast mound is transformed into a breast facsimile that more closely resembles the original breast. Although numerous nipple reconstruction techniques are available, all have been plagued by eventual loss of long-term projection. In this report, the authors present a comparative assessment of nipple and areola projection after reconstruction using either a bell flap, a modified star flap, or a skate flap and full-thickness skin graft for areola reconstruction. The specific technique for nipple-areola reconstruction following breast reconstruction was selected on the basis of the projection of the contralateral nipple and whether or not the opposite areola showed projection. Patients with 5 mm or less of opposite nipple projection were treated with either the bell flap or the modified star flap. In patients where the areola complex exhibited significant projection, a bell flap was chosen over the modified star flap. In those patients with greater than 5-mm nipple projection, reconstruction with a skate flap and full-thickness skin graft was performed. Maintenance of nipple projection in each of these groups was then carefully assessed over a 1-year period of follow-up using caliper measurements of nipple and areola projection obtained at 3-month intervals. The best long-term nipple projection was obtained and maintained by the skate and star techniques. The major decrease in projection of the reconstructed nipple occurred during the first 3 months. After 6 months, the projection was stable. The loss of both nipple and areola projection when using the bell flap was so remarkable that the authors would discourage the use of this procedure in virtually all patients.  相似文献

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.  相似文献

The microflora of the mammary glands in the area of the nipple, the areola and the adjacent skin was studied by the methods of washings and impression. 120 nonpregnant women and 164 pregnant women were examined. The pregnant women showed a higher level of the contamination of the above-mentioned sites. The highest density of bacterial population was detected in the area of the nipple and the lowest density, on the skin surrounding the areola. Coagulase-negative staphylococci proved to be the most numerous organisms among all bacterial population found on the skin of the mammary glands of pregnant women. Of these staphylococci, S. epidermidis was most frequently isolated, its isolation rate being higher in the pregnant women than in the nonpregnant ones.  相似文献

The preservation of sensitivity within the nipple-areola complex is of paramount importance to patients presenting for reconstructive and aesthetic breast procedures. Previous attempts to measure sensation in the breast before and after surgery have relied primarily on the Semmes-Weinstein monofilament test, which is an imprecise study that measures the logarithm of force necessary to bend a series of six to 20 filaments. Within the last 10 years, various authors have published normative pressure threshold data for the breast that have varied by a magnitude of greater than 10-fold. Recently, precise anatomic studies have been performed that have elucidated the innervation of the nipple-areola complex medially and laterally from cutaneous branches of the intercostal nerves. Despite this knowledge, no quantitative sensibility studies have yet been performed that compare postoperative sensation when medially versus laterally innervated pedicles have been used in reduction mammaplasty. The present study is the first to use computer-assisted neurosensory testing to generate normal breast sensation data and to compare sensory outcomes between the inferior and the medial pedicle techniques of reduction mammaplasty.A total of 34 patients were divided into four groups and underwent breast sensory testing (67 breasts total) using the Pressure-Specified Sensory Device, a computer-assisted force transducer that measures static and moving one and two-point discrimination. Sensation in the nipple and in the four quadrants of the areola was measured. Groups I and II were composed of 17 unoperated controls with breast sizes ranging from 34A to 36C (group I; 18 breasts) and 36DD to 46EE (group II; 16 breasts) who presented to a general plastic surgery clinic. Groups III and IV were composed of 17 patients who underwent either medial or inferior pedicle reduction mammaplasty between July of 1997 and March of 1999. Pressure thresholds in the most sensitive breasts were as low as 0.3 g/mm2, a marked contrast to data from previous studies using Semmes-Weinstein monofilaments documenting the lowest recordable pressure threshold as greater than 2 g/mm2. Several findings from previous studies using Semmes-Weinstein monofilament testing were confirmed in unoperated controls, including an inverse relationship between sensitivity and breast size, superior nipple sensitivity when compared with the areola, and significant interpatient variability with respect to static and moving two-point discrimination among women matched according to age and breast size. When comparing medial with inferior pedicle reduction mammaplasty patients, it was found that despite significantly greater reductions using the medial pedicle technique (mean of 1.7 kg versus 1.1 kg of breast tissue removed), there were no significant differences in postoperative sensory outcomes in the sample size of 17 patients. Furthermore, within each group of patients undergoing either the medial or inferior pedicle technique, the amount of breast tissue removed did not correlate with postoperative sensory outcomes.Computer-assisted quantitative neurosensory testing is a highly accurate technique for measuring sensibility. The use of this technology demonstrates a 10-fold difference in measurable sensory thresholds in normal patients from preexisting data using Semmes-Weinstein monofilaments. Advances in measurement methods have allowed the authors to compare postoperative sensory outcomes reliably using two popular techniques of reduction mammaplasty.  相似文献

A Z-mammaplasty with minimal scarring   总被引:1,自引:0,他引:1  
An improved technique for reduction mammaplasty is described that has the advantage of giving a satisfactory final shape to the breast while producing a minimal scar. The method involves periareolar deepithelialization with displacement of the nipple-areola complex, partial subcutaneous mastectomy at the base of the mammary cone, and a Z-plasty to interlock two triangles of skin left after the removal of a little excess skin in the region above the inframammary fold. The Z-plasty adds skin vertically to the inferior pole, resulting in a better final shape and reducing tension around the areola. Any further excess skin is left to retract spontaneously. The best indications for this operation are in young women with elastic skin free of striae "gravidarum." Our experience now covers 53 patients aged 14 to 30 years with reductions of up to 900 gm per breast, and we have encountered no major complications over a 3-year follow-up period.  相似文献

Guidelines in concentric mastopexy   总被引:3,自引:0,他引:3  
The scope and technique of concentric mastopexy remain unclear and controversial. In our hands, the procedure has application for mild nipple ptosis, glandular ptosis, and areola asymmetry, as well as the tuberous breast. Early disappointment has changed to increasing satisfaction as we have gained confidence in predicting our results based on the identification of three simple principles of concentric mastopexy. The first and most important, which states Doutside less than or equal to Doriginal + (Doriginal - Dinside), requires that the outer concentric circle must be drawn not to exceed the original areola diameter by more than the original areola diameter exceeds the inner concentric circle diameter. The second principle, Doutside less than or equal to 2 X Dinside, recommends that the outer circle diameter be drawn not to exceed twice that of the inner circle, to prevent poor scarring or over flattening of the breast. The third principle, Dfinal = 1/2(Doutside + Dinside), allows prediction of the final areola size as the average of the diameters of the inner and outer concentric circles. These three principles allow excision of a maximum amount of areola and periareola skin without the side effect of poor scars, dilated areola, or misshapened breasts. Applying these three principles to concentric mastopexy with or without augmentation mammaplasty, one may confidently correct a wide variety of deformities, producing more symmetrical, attractive breasts with areolae of a predictable size.  相似文献

A method of changing the absolute position of the areola if poor positioning occurs after surgery is described. This method uses tissue expansion as an intermediate step and in so doing allows movement with no new scars. There is no reason that medial, lateral, or superior malpositions could not be corrected in this way. Most breast reduction patients with bottoming out will not need this two-stage procedure if the areola is not too high in the beginning.  相似文献
