Surgical correction of gynecomastia in thin patients. Indications for and results of surgical therapy for male gynecomastia. Ceasing to use the offending agent may result in regression of GM. If GM either persists or becomes more severe and is associated with pain, psychological distress or embarrassment caused by avoidance of activities in which the chest is exposed, pharmacological and surgical therapeutic options should be considered, especially when the patient wishes to pursue treatment.

With the assumption that there is a high possibility that the GM may spontaneously regress, the decision on when to treat is often difficult. Androgens, antiestrogens and aromatase inhibitors have been tested for GM treatment with some success. Danazol is an antigonadotropic drug with a weak androgen effect that acts to counterbalance the stimulatory effects of estrogens. A daily dose of mg may provide effective control over the symptoms.

Dihydrotestosterone heptanoate, which does not undergo peripheral aromatization, was used in one study for a small number of pubertal cases with excellent results.

Selective estrogen receptor modulators, such as tamoxifen and raloxifene are fairly safe and should be beneficial. Two studies have compared tamoxifen with other substances. Ting et al. Three studies have investigated the effectiveness of anastrozole, which is a potent aromatase inhibitor used for treating pubertal GM.

While two observational studies with small samples have provided encouragement for the use of anastrozole, 66,67 a well-designed randomized controlled trial on 80 pubertal boys found that anastrozole was not significantly more effective than placebo for reducing the breast volume calculated from ultrasonography measurements Tamoxifen was considered superior to anastrozole for prevention of bicalutamide-induced GM in men with prostate cancer.

Overall, the use of drugs for GM treatment is only supported by very low quality of evidence, and the uncertainty about the balance between their benefits and potential harm should be highlighted to candidate patients. GM of long duration is unlikely to regress spontaneously and may often progress to dense fibrosis and hyalinization.

So far, for long-standing symptomatic GM, medical therapy is less likely to be effective because the stroma is mostly fibrotic. Traditionally, surgery has been the mainstay of therapy in such cases, as well as for men for whom medical therapy fails, is not tolerated or is declined, or for whom tissue removal is preferable for cosmetic reasons.

In some cases, denial of cosmetic correction or procrastination in providing this may create an additional unnecessary burden on an already overloaded psyche. The aims of surgical treatment of GM are to restore normal chest contours, eliminate the inframammary fold, correct the NAC position, remove redundant skin, create symmetry between the two halves of the chest and minimize scarring.

There are many surgical techniques and treatment protocols for correcting GM in the literature. The presence of cutaneous ptosis and the amount of excessive skin are decisive in guiding the choice between surgical treatment methods.

In our opinion liposuction alone should not be used and is limited only to cases of pure pseudogynecomastia. Surgical treatment of gynecomastia requires an individualized approach. In grade I, the enlargement is caused solely by glandular proliferation without adipose accumulation. Surgical correction involves mammary adenectomy performed by a semicircular inferior periareolar incision. Liposuction is not required Figure 6. In these cases, liposuction and surgical excision must be combined in the same operation Figure 7.

We recommend that the procedure should begin with vacuum lipoplasty and should be followed by mammary adenectomy by means of a classical periareolar incision. It is worth noting that other incisions may also allow good results, such as intra-areolar, pull-through or endoscopic procedures. Mammary adenectomy without liposuction leads to unsatisfactory outcomes, with an uneven surface or asymmetry.

In grade III, the operation begins with liposuction and is followed by glandular excision with periareolar removal of the tissue. It is necessary to detach the excess skin to obtain a good chest silhouette.

The surgical planning is undertaken bearing in mind the necessity to preclude the stigma of big scars. For the final appearance, it is always preferable for the scars to be restricted to the periareolar area. As a routine, a double-circle incision is performed over the skin, thereby making it possible to remove the epithelial tissue from an annular portion of skin that is as large as needed for each case Figure 8.

Because the epidermis has been removed, round-black suturing is done, which gives rise to a circumferential periareolar scar. The hallmarks of grade IV GM are severe ptosis and a large amount of redundant skin. One of the techniques for reduction mastoplasty is used to remove gland and skin and flatten the chest outline. Inverted T-shaped resection, with NAC migration using superior or superior-medial dermic pedicles, similarly to the procedure for mammoplasty in women, may be used.

Other techniques such as those with horizontal or oblique incisions can also be used Figure 9. When patients strongly desire to have inconspicuous scars confined to the periareolar region, sequential double-circle skin incisions in a multi-step procedure are a valid option.

Since GM may be harboring neoplasia, histopathological analysis of the resected tissue is mandatory. Closed suction drains are placed after the excisions and removed when the output over 24 hours has decreased to less than 30 ml. To facilitate tissue accommodation and achieve an even chest surface, we advise patients to wear elastic compressive garments for a period of months.

Hypoesthesia of the nipple is very common and is transient. The cosmetic results and patient satisfaction after surgery are high. After confirming the diagnosis, searching for a specific cause and classifying the case according to severity grade, the therapy for GM should be personalized. Lifestyle guidance, reassurance, medical treatment and surgical correction are valid tailored therapeutic options.

They often grow unevenly. It is often caused by changes in levels of the female hormone estrogen and the male hormone testosterone. Other things may cause it as well. Most cases happen when a preteen or teenage boy is going through puberty. But it can also happen to newborn babies and older men. It often goes away on its own. In some cases, hormone therapy is needed. Surgery may also help treat the condition.
