Breast-feeding after inferior pedicle reduction mammaplasty

The breast-feeding practices of a series of postpartum women, who had undergone prior reduction mammaplasty by means of an inferior pedicle approach, are reported in this retrospective study. Also identified are the factors that influenced the decision to breast-feed postoperatively. From a patient pool of 544 individuals who elected to have reduction mammaplasty between 1984 and 1994 (age range, 15 to 35 years), 334 could be contacted and interviewed by means of telephone by using a standardized questionnaire. Successful breast-feeding was defined as the ability to feed for a duration equal to or greater than 2 weeks. Seventy-eight patients had children after their breast reduction surgery. Fifteen of the 78 patients (19.2 percent) breast-fed exclusively, 8 (10.3 percent) breast-fed with formula supplementation, 14 (17.9 percent) had an unsuccessful breast-feeding attempt, and 41 (52.6 percent) did not attempt breast-feeding. Of the 41 patients not attempting to breast-feed, 9 patients did so as a direct consequence of discouragement by a health care professional. Further reasons for feeding with supplementation, having an unsuccessful attempt, and not attempting to breast-feed are presented. Of the 78 women who had children postoperatively, a total of 27 were discouraged from breast-feeding by medical professionals with only 8 of the 27 (29.6 percent) subsequently attempting, despite this recommendation. In comparison, 26 patients were encouraged to breast-feed; nineteen (73.1 percent) of them did subsequently attempt breast-feeding. This rate is statistically significant by using a chi2 test with 1 df(p = 0.0016). Postpartum breast engorgement and lactation was experienced by 31 of the 41 patients not attempting to breast-feed. Of these 31 patients, 19 believed that they would have been able to breast-feed due to the extent of breast engorgement and lactation experienced. Given the use of an inferior flap mammaplasty technique and patient encouragement, the possibility for breast-feeding after reduction mammaplasty exists. This prevalence falls near the breast-feeding rate found in the population not having undergone breast surgery, according to an article in the Canadian Journal of Public Health.     

Reliability of inferior pedicle reduction mammaplasty in burned oversized breasts

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.     

A comparison of complication rates in large and small inferior pedicle reduction mammaplasty

The main objective of this retrospective study was to determine whether the rates of complications are higher in large reductions (> or =1000 g per breast) as compared with smaller reductions (< or =999 g per breast) using the inferior pedicle technique. A retrospective chart review of 133 consecutive patients operated on between October of 2000 and March of 2002 was undertaken. Complication data were recorded and analyzed on a per-breast basis. Two hundred sixteen breasts had reductions of 999 g or less, whereas 50 breasts had reductions of 1000 g or more. The overall mean follow-up period was 152 days (range, 20 to 522 days). There were no statistically significant differences in the rates of nipple necrosis, hematoma formation, seroma, delayed healing, culture-positive wound infection, fat necrosis, cyst formation, nipple sensation, or hypertrophic scarring between the large and small reductions. However, the rate of wound dehiscence was significantly lower in the smaller reduction group. The rates of wound dehiscence and hypertrophic scarring were also significantly lower in patients who had received at least 5 days of postoperative antibiotics. A statistically significant difference was also reported for clinical wound infection (p < 0.0005). Body mass index had no statistically significant effect on the rate of nipple necrosis, hematoma formation, fat necrosis, cyst formation, nipple sensation, or hypertrophic scarring. However, body mass index had a statistically significant effect on delayed healing, wound dehiscence, and culture-positive wound infection. A higher mean body mass index predicted a delayed healing, wound dehiscence, and infection. The inferior pedicle technique is a safe method of breast reduction regardless of degree of parenchymal resection. However, the use of postoperative antibiotics for at least 5 days is recommended to reduce rates of wound dehiscence and improve postoperative scarring.     

Superomedial pedicle technique of reduction mammaplasty

A series of 148 patients who underwent reduction mammaplasty utilizing the superomedial pedicle technique is presented. Resections as large as 4100 gm per breast with nipple-areola transpositions up to 30 cm were done with reliable nipple-areola survival, including preservation of sensation. The superior pedicle technique of breast reduction is recognized by many as technically easier and capable of producing a longer-lasting aesthetic effect. Classically, however, it has been limited to smaller resections. By incorporating the medial quadrant in the superior pedicle, more aggressive reductions can be safely undertaken with the same excellent results. Details of the procedure, the anatomic basis for its success, and complications are discussed.     

Preservation of projection after reduction mammaplasty: long-term follow-up of the inferior pedicle technique

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.     

Quantitation of breast sensibility following reduction mammaplasty: a comparison of inferior and medial pedicle techniques

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.     

Medial pedicle reduction mammaplasty for severe mammary hypertrophy

Current options in reduction mammaplasty for severe mammary hypertrophy include amputation with free-nipple graft as well as the inferior pedicle and bipedicle techniques. Complications of these procedures include nipple-areola necrosis, insensitivity, and hypopigmentation. The purpose of this study was to determine whether medial pedicle reduction mammaplasty can minimize these complications. Twenty-three patients with severe mammary hypertrophy were studied. The medial pedicle successfully transposed the nipple-areola complex in 44 of 45 breasts (98 percent). Mean change in nipple position was 17.1 cm, and mean weight of tissue removed was 1604 g per breast. Nipple-areola sensation was retained in 43 of 44 breasts (98 percent) using a medial pedicle. Hypopigmentation was not observed, and central breast projection was restored in all patients. This study has demonstrated that medial pedicle reduction mammaplasty is a safe and reliable technique and should be given primary consideration in cases of severe mammary hypertrophy.     

Tissue oxygenation and perfusion in inferior pedicle reduction mammaplasty by near-infrared reflection spectroscopy and color-coded duplex sonography

Near-infrared reflection spectroscopy has been used in various experimental and clinical settings to investigate tissue perfusion and oxygenation noninvasively. Its application in plastic surgery has only recently been reported. The current study used near-infrared reflection spectroscopy to monitor cutaneous microcirculation in breast skin flaps after inferior pedicle reduction mammaplasty. Thirty patients underwent bilateral reduction mammaplasty by a modified Robbins technique. Near-infrared reflection spectroscopy measurements were performed preoperatively and postoperatively at several defined positions of the breast. The reflection spectroscopy system was capable of detecting absolute values of total hemoglobin in milligrams per milliliter of tissue and tissue hemoglobin oxygen saturation in percent. Color-coded duplex sonography was used to visualize nutrient vessels of the inferior dermoglandular pedicle and to measure systolic peak flow in the arteries supplying the nipple-areola complex. Reflection spectroscopy values were examined for changes during the postoperative course. Reflection spectroscopy and duplex sonography values were analyzed for differences between patients with normal and compromised skin flap perfusion and wound healing, which was assessed clinically and by ultrasound. Preoperative reflection spectroscopy values demonstrated local, regional, and interindividual variations. Postoperatively, characteristic changes of tissue hemoglobin oxygen saturation and total hemoglobin were observed in all patients during the 2-week follow-up. Reflection spectroscopy values differed significantly between breast and nipple-areola skin. Tissue hemoglobin oxygen saturation was significantly lower, and total hemoglobin significantly higher, in patients with impaired wound healing compared with patients having normal wound healing. However, systolic peak flow in arteries of the inferior dermoglandular pedicle did not reveal differences between patients with impaired or normal wound healing of the nipple-areola complex. Near-infrared reflection spectroscopy allows the detection of hemoglobin content and oxygenation in skin flaps. Changes in tissue hemoglobin oxygen saturation and total hemoglobin reflect hemodynamic changes in skin flaps during normal and pathological wound healing. Because of considerable intraindividual and interindividual variations, trend values seem to be superior to single measurements. Although in this study, near-infrared reflection spectroscopy was capable of distinguishing between normal and impaired perfusion in skin flaps in a clinical model, its future implication may be the early detection of vascular compromise in free flaps.
