Gynecomastia: analysis of 159 patients and current recommendations for treatment

Gynecomastia has been treated surgically in 159 patients during the past 22 1/2 years. Prior to 1980, all patients had traditional excision, which was followed by a high incidence of complications and undesired sequelae, not the least of which was that the results of this aesthetic operation were often unaesthetic. Since 1980, when suction lipectomy became the cornerstone of treatment, the results have been much better. As a result, current recommendations for treatment are as follows: If the gynecomastia is entirely due to fat, suction lipectomy alone is sufficient treatment. However, since suction will not remove breast parenchyma, those patients whose gynecomastia is due to parenchymal hypertrophy also require local excision of the parenchyma. Skin excision is rarely, if ever, necessary.     

Classification and management of gynecomastia: defining the role of ultrasound-assisted liposuction

Gynecomastia, or excessive male breast development, has an incidence of 32 to 65 percent in the male population. This condition has important physical and psychological impacts. Advances in elucidating the pathophysiology of gynecomastia have been made, though understanding remains limited. Recommendations for evaluation and workup have varied and are often arbitrary. A diagnostic algorithm is suggested, with emphasis on a comprehensive history, physical examination, and minimizing unnecessary diagnostic testing. Medical management has had limited success; surgical therapy, primarily through excisional techniques, has been the accepted standard. Although effective, excisional techniques subject patients to large, visible scars. Ultrasound-assisted liposuction has recently emerged as a safe and effective method for the treatment of gynecomastia. It is particularly efficient in the removal of the dense, fibrous male breast tissue while offering advantages in minimal external scarring. A new system of classification and graduated treatment is proposed, based on glandular versus fibrous hypertrophy and degree of breast ptosis (skin excess). The authors' series of 61 patients with gynecomastia from 1987 to 2000 at the University of Texas Southwestern Department of Plastic Surgery demonstrated an overall success rate of 86.9 percent using suction-assisted lipectomy (1987 to 1997) and ultrasound-assisted liposuction (1997 to 2000). The authors have found ultrasound-assisted liposuction to be effective in treating most grades of gynecomastia. Excisional techniques are reserved for severe gynecomastia with significant skin excess after attempted ultrasound-assisted liposuction.     

The use of liposuction to contour cherubism

Yet another application of suction lipectomy equipment is presented to remove the pathologic tissue in cherubism. Owing to the variations of consistency of the material in this condition, this technique may not be successful in all patients, but it is certainly recommended when indicated.     

Subcutaneous pseudobursa secondary to suction and surgery

Suction lipectomy has been used throughout the regions of the body to remove vast amounts of subcutaneous fat. The blunt technique allows for a multiplicity of small (4 to 6 mm) channels to be created and the fat removed by suction with little disturbance of the overlying skin, the supporting septa, vessels, or nerves. Abdominolipectomy has been successfully performed for decades, in which large amounts of skin and subcutaneous fat are removed by sharp dissection. The undermining involved in an adbominolipectomy extending from the xiphoid to pubis and laterally to the level of the iliac crest and then supplemented by the suction technique has led to the formation, in some cases, of chronic seromas not relieved by multiple aspirations. Healing and contractions of these seromas causes a deformity of the overlying skin, because it is puckered and drawn upon itself. This results in the formation of a subcutaneous pseudobursa lined by collagen sheets but no epithelial cells. We present 9 patients who have demonstrated this phenomenon. We suggest that in the largest resections, safety is best served by waiting a period of at least 6 weeks between suction and subsequent resection.     

A new device to avoid unfavorable results in suction lipectomy

A cannula system with guard wheel attachment and special wrench has been developed and used for suction lipectomy. The devices facilitate the procedure, and results are more consistent and dependable.     

Suction lipectomy of the neck

Suction lipectomy of the neck has been advocated in other reports. However, because of skin laxity, a simultaneous face/neck lift has been performed usually. In this series of 49 patients, ages 18 to 73, removal of submandibular fat was performed by suction lipectomy. A simultaneous face/neck lift was not done. In addition, no skin was excised. On the contrary, the apparent excess skin was found to be required for contouring. Approximately one-third of the patients had a simultaneous chin implant. Others had different aesthetic surgical procedures performed during the same operation. The removal of neck fat by suction has proven to be more efficacious than excisional methods of lipectomy. The risks of operation have been found comparable to suction lipectomy performed in other anatomic locations.     

En bloc cervical lipectomy for treatment of the problem neck in facial rejuvenation surgery

The treatment of cervical fat in facial aesthetic surgery has received much attention in recent years. Suction lipectomy has become a very popular technique for removing cervical fat because it is easy to perform and results in few complications. This paper describes the en bloc excision of cervical fat in conjunction with rhytidectomy. The senior author has treated 1,000 patients over 17 years using this technique with a high degree of patient satisfaction and minimal morbidity. Although suction lipectomy alone may be indicated for the younger patient, our experience suggests that the en bloc excisional technique is the treatment of choice in the older patient in whom a rhytidectomy is also indicated. In contrast with suction lipectomy, we have found that the en bloc excision of cervical fat allows for more anatomic dissection and facilitates removal of greater amounts of fat and better redraping of the cervical skin.     

Suction lipectomy: complications and results by survey

In October of 1983, we sent a questionnaire on suction lipectomy to 2524 U.S. and Canadian members of the American Society of Plastic and Reconstructive Surgeons. Six-hundred and twelve plastic surgeons returned questionnaires (24.2 percent response rate). One-hundred and seven responding surgeons reported 1573 operations in which suction lipectomy with or without skin excision was used for 2685 procedures on various parts of the body. In the subset of 1249 operations in which suction lipectomy only was used to treat 2261 anatomic areas, surgeons reported greater than 80 percent good or excellent aesthetic results. The overall complication rate was 9.3 percent. The most frequent complications were persistent hypesthesia (2.6 percent), seroma (1.6 percent), and persistent edema (1.4 percent). Skin pigmentation, pain, hematoma, infection, and slough each occurred with an incidence of 1.0 percent or less. Based on the results of this survey, suction lipectomy is a valuable new modality for surgical improvement of body contour.     

Minimal surgical access to treat gynecomastia with the use of a power-assisted arthroscopic-endoscopic cartilage shaver

Gynecomastia is the most common benign condition of the male breast. The authors present a new method of treatment for gynecomastia that combines traditional liposuction in conjunction with a shaver technique to effectively remove the fibrofatty and the glandular tissues of the male breast and avoid areolar incisions. Twenty-five patients were treated in this fashion, and each patient demonstrated a smooth, masculine breast contour with well-concealed scars in the inframammary folds, eliminating the stigma of breast surgery. The procedure is technically straightforward and provides consistent results. It is offered as an additional option for the treatment of gynecomastia.     

Concentric circle operation for massive gynecomastia to excise the redundant skin.

A technique is described for excising the excess skin in gynecomastia operations, using a concentric "circle" design to remove a calculated amount in the vertical in the horizontal directions. The sole residual scar is a circular one around the periphery of the areola.     

Combined use of ultrasonic liposuction with the pull-through technique for the treatment of gynecomastia

The authors present a method of treatment for gynecomastia that combines the use of two techniques of soft-tissue contouring. This method uses ultrasonic liposuction in conjunction with the pull-through technique of direct excision to effectively remove the fibrofatty tissue of the male breast and the fibrous breast bud through a single 1-cm incision. Fifteen patients were treated in this fashion, and each patient demonstrated a smooth, masculine breast contour with a well-concealed scar, which eliminates the stigma of breast surgery. The procedure is technically straightforward and provides consistent results. It is offered as an additional option for the treatment of gynecomastia.     

Gynecomastia: pathomechanisms and treatment strategies

Gynecomastia is common in adolescents and adults, and reflects an underlying imbalance in hormonal physiology in which there is an increase in estrogen action relative to androgen action at the breast tissue level. Most patients have persistent pubertal gynecomastia or breast glandular enlargement from medications, age-related reduction in testicular function, or idiopathic causes. Gynecomastia must be differentiated from pseudogynecomastia due to increased breast adipose tissue, as well as from breast carcinoma. The evaluation of the causes of gynecomastia can be accomplished through history, physical examination and a few laboratory tests. Painful gynecomastia of recent onset may respond to antiestrogen therapy. Surgical removal is the mainstay for long-standing gynecomastia or glandular enlargement that is unresponsive to medical therapy.     

Suction mammaplasty: the use of suction lipectomy to reduce large breasts

The use of suction lipectomy to reduce breast volume is described. The technique applies only to a very limited group of patients whose nipple-areola complexes are normally located and whose enlargement is primarily fibrofatty in nature. Suction mammaplasty can be used as a sole technique in congenital asymmetry or in post-reduction enlargement or asymmetry.     

Hand rejuvenation with structural fat grafting

A simple, reliable technique of autologous fat grafting for long-lasting rejuvenation of the dorsum of the hand is presented. With this technique, small intact parcels of fatty tissue are harvested with a syringe and a blunt 3-mm cannula. Then, most of the nonviable components are removed from the harvested subcutaneous material by centrifugation, decanting, and wicking. Finally, a 17-gauge blunt cannula places the fat in minuscule parcels of tissue with many passes through five or six tiny incisions in the hand. Separation of the tiny parcels of fat maximizes contact between the surfaces of the transplanted fat and surrounding recipient tissues to encourage integration, anchoring, and long-term survival. Structured, purposeful placement of a thin layer of transplanted fat rejuvenates the dorsal hand by restoring a slight fullness to atrophic subcutaneous tissue, by softening the color and definition of exposed extensor tendons and dorsal hand veins, and by supporting the aging skin.     

Skin retraction following suction lipectomy by treatment site: a study of 500 procedures in 458 selected subjects

I identified 500 suction lipectomy procedures involving sites on the body and in the cervicofacial region in 458 selected patients and studied the influence of treatment site on postoperative skin retraction by comparing preoperative and postoperative skin condition. Postoperative skin condition was evaluated first in the immediate postoperative period (second or third day); then at a more remote date (after at least 2 months of follow-up). On the body, restoration of the preoperative condition of the skin was obtained in 94.6 percent of treatment sites in the immediate postoperative period; after a longer follow-up, this proportion was 87.9 percent because of delayed development of modifications. The time interval needed to obtain a stable result increased with increasing age, regardless of the nature of this result, as well as with the total amount of fat removed. On the neck, liposuction improved or even eliminated preexisting skin looseness, and this improvement was even more noticeable as follow-up increased. The neck thus appears as the site of choice for suction lipectomy. On the face, in contrast, favorable results deteriorated over time, a finding that leads me to advocate combination with a face-lift whenever ptosis is present. Thus treatment site obviously has a substantial impact on the potential of the skin for retracting postoperatively.     

Lipodissection in body sculpturing: the dry procedure

We have used the honeycombed suction lipectomy (wet and/or dry) in over 700 patients. It represents a major advancement in the treatment of the localized adiposities of the body. Its advantages are eliminating the need for long, unsightly scars and reducing operating time and morbidity. Selection of appropriate patients is of paramount importance for reliable results because this technique is truly sculpting of the soft tissues. Results improve also with the proper training and experience of the surgeon. The indications and complications have been discussed. This technique (honeycombed suction lipectomy) appears more reliable than suction curettage that employs sharp dissection.     

Tumescent and dry liposuction of lower extremities: differences in lymph vessel injury

Lipectomy is a standard procedure in plastic surgery. Until now, however, there was no definite information about the influence of different liposuction techniques (tumescent versus dry liposuction) on the integrity of lymph collectors during this procedure. To study the effect of these liposuction techniques on the incidence of lymph vessel injury, postmortem lymphatic preparations were done in nine human cadavers (18 lower extremities). Conventional liposuction with a blunt 4-mm cannula in the dry technique (n = 29 regions) was compared with the tumescent technique (n = 26). Liposuction was performed in parallel to the superficial lymph vessels (longitudinal suction) or transversally in an 80-degree to 90-degree angle to the extremity (vertical suction). Careful surgical preparation of different regions followed. A specific macroscopic lymph vessel injury score was applied to differentiate three degrees of lymph vessel lesions according to the extravasation of patent blue. In all lower extremities, postmortem lymph flow occurred as indicated by patent blue staining of the lymph vessels. Injection of fluid that is obligatory during tumescent suction did not result in grade 2 injury. On the contrary, tumescent suction overall produced significantly fewer lymph vessel lesions when compared with the dry technique (p < 0.05). Longitudinal liposuction produced significantly less injury when compared with vertical suction (p < 0.05). Tumescent suction and dry suction were equally effective in removing adipose aspirates, as verified by circumference measurements. In addition, tumescent liposuction is unlikely to cause major lesions of epifascial lymph vessels during suction procedures vertical to the extremity axis. Therefore, in this respect, this technique is superior to dry suction.     

Suction-assisted lipectomy for correction of 202 figure faults in 101 patients: indications, limitations, and applications

Since its introduction in the United States, suction-assisted lipectomy has proven to be a safe, effective technique for correction of figure faults. It has been greeted with considerable skepticism by many practitioners, however, owing to the poor results many have obtained in their initial attempts to apply similar techniques. Suction lipectomy using the blunt technique is a safe procedure that can yield consistently good results when appropriately applied. It is suggested that the principal reason others have had difficulty involves problems in patient selection. The technique may not be effective for the correction of generalized obesity and cannot be expected to dramatically alter overall appearance. Patients should be selected for treatment of specific "figure faults" and educated as to what may realistically be expected. The patient's emotional and psychological condition must be taken into consideration. We report a series of 101 patients treated with a total of 202 separate suction lipectomy procedures with good results and only two minor complications. A survey of patients treated by the method reveals a generally high level of satisfaction and some of the ambivalence that might be anticipated from such a technique.     

Abdominoplasty and abdominal wall rehabilitation: a comprehensive approach

Standard abdominoplasty techniques involve a low horizontal or W skin excision, muscle plication, and umbilical transposition. Newer techniques include suction-assisted lipectomy, the use of high lateral tension with fascial suspension, and external oblique muscle advancement. The author has modified these traditional procedures and added new techniques to improve the aesthetic and functional results of the abdominoplasty procedure. This modification provides a comprehensive approach to abdominal wall aesthetic improvement and rehabilitation. The comprehensive approach described includes four components: the "U-M dermolipectomy," "V umbilicoplasty," the rectus abdominis "myofascial release," and suction-assisted lipectomy. The patient is marked while standing for areas of suction lipectomy and undermining. The lower incision is designed as an open U with the lateral limbs placed inside the bikini line. The upper incision is a lazy M with the higher peaks located at the level of the flanks. Subcutaneous hydration is achieved to perform suction along the flanks, waistline, and iliac areas. Gentle suction of the flaps is also performed. The umbilicus is cored out in a heart shape. The flaps within the U-M marks are excised, and the undermining is performed to the xiphoid and costal margins. The rectus diastasis is marked, and the anterior rectus fascia is incised at the junction of the medial third with the central third of the width of the rectus sheath. Horizontal figure-eight plication sutures by using the lateral fascial edge enable easier infolding of the central tissue. The new recipient of the umbilicus is made by an incision in a V shape on the abdominal flap. The umbilicus is telescoped, and the triangular flap of the abdomen is sutured to the triangular defect of the umbilicus. Skin flap fixation to the umbilicus relieves tension in the lower portion of the flap. The upper skin flap, which is cut in an M manner, provides lateral tension and matches the length of the lower flap. A standard fascial suspension is used and closure is performed in layers. The techniques described here are intertwined procedures. Each facilitates the accomplishment of the other procedure, and they complement each other. They all attain the 12 objectives of the abdominoplasty described. These combined techniques have been used in 104 patients in a period of 11 years. Complications were minimal and easily manageable, except for one patient who required excision of a pseudobursa and retightening of the lower quadrants of the abdominal wall musculature to correct extreme lordosis. A comprehensive approach for the treatment of complex abdominal wall aesthetic and functional defects is presented. These require thoughtful integration of the four components mentioned. This approach has allowed predictable, reproducible, and aesthetically pleasing results.     

Treatment of pubertal gynecomastia with the specific aromatase inhibitor anastrozole

Gynecomastia can be detected in up to 70% of boys during puberty and in about one third of adult males. An imbalance of estrogen to androgen tissue levels is believed to be the major reason for the development of gynecomastia; as a result most medical treatments so far have tried to lower the estrogen level. Five boys with pubertal gynecomastia and breast tenderness were treated for 6 months with the selective aromatase inhibitor anastrozole. Initial plasma levels of estradiol (E2), testosterone (T), androstenedione, dehydroepiandrosterone sulfate (DHEA-S) and gonadotropins were normal. DHEA-S showed a significant rise during treatment. T and androstenedione showed no significant change during treatment. E2 decreased with therapy, although to no statistically significant extent. The E2/T ratio decreased significantly during the treatment. Breast size decreased in 4 out of 5 patients, and in 1 of these 4 boys glandular breast tissue disappeared completely. The longer the duration of gynecomastia before anastrozole administration, the smaller was the reduction of breast size. Breast tenderness was resolved in all boys within 4 weeks. No adverse effects were recorded. Since the aim of medical treatment is the total disappearance of breast tissue, anastrozole, as previous aromatase inhibitors, is of limited effect. However, anastrozole seems to be of benefit for the treatment of tenderness in gynecomastia and for patients in whom surgery is particularly risky. However, as spontaneous disappearance of pubertal gynecomastia is common, further double-blinded, placebo-controlled trials are necessary before a definite conclusion can be drawn about the effectiveness and the side effects of this therapy.
