Background: Transsexual (TS) people are those who assigned one sex at the birth but identified their gender in what society considers the opposite direction. Studies showed that gender reassignment surgery (GRS) had greatly improved the quality of life in TS patients. Materials and Methods: We studied 20 patients who had legally the permission of being underwent the sex reassignment surgery in Imam Khomeini Hospital Complex of Tehran, Iran. For all patients, concentric periareolar subcutaneous mastectomy was performed. The patients were followed up for 1 year and the results were evaluated. Results: Our findings show an acceptable scar formation after 1 year of the sex reassignment surgery. There was only one complication which was managed conservatively. About 90% of patients were satisfied from the results of surgery, and no one was less/unsatisfied. The average score of nipple sensation was 7.9 and no changes in nipple pigmentation was observed. Conclusion: Concentric periareolar mastectomy is probably a good technique of subcutaneous mastectomy in female to male GRS in patients with small and medium size of the breast and poor skin elasticity. The result scar in this method is acceptable and gives the patients a good feeling of having male chest.

| Introduction|| |
Transsexual (TS) people are those who assigned one sex at the birth but identified their gender in what society considers the opposite direction. According to a study in 2017, the incidence rate of transsexualism and the annual average of demands were 2.5 in 100,000 and 130 inhabitants, respectively.
In 1989, a group of physiologists and psychologists laid down a guideline to select the best candidate of gender reassignment surgery (GRS). Subsequently, studies have shown a significant improvement in symptoms of depression, psychological stability, and social and sexual life postoperatively.,,
Studies showed that GRS had greatly improved the quality of life in TS patients.,, Mammoplasty increases self-confidence and improves body image and better gender identification among female-to-male (FTM) TS people.
According to this fact that hormonal therapy has limited effect on breast size, subcutaneous mastectomy includes the surgical excision of gland tissue helps to create male chest anatomy in FTM candidates. Following the hysterectomy and subcutaneous mastectomy in GRS, vaginectomy, reconstruction of the horizontal part of urethra, scrotoplasty, and penile reconstruction will be performed.,, For these patients, the objective is to find a technique in which we minimize the chest-wall scar, reducing and proper positioning of nipple and areola, and obliterate the inframammary fold., Some authors believe that skin excess determines the appropriate GRS technique.,,
There are different techniques which are being used in GRS.,,,, Among these methods, we chose a technique with minimum resulting scars and maximum access to the breast tissue. In concentric periareolar technique, reducing and positioning of the areola will be obtained to remove the excess skin. On the other hand, this method leads to desirable scars because of confining it to the circumference of the areola.
In this study, we evaluated 20 patients who underwent concentric periareolar subcutaneous mastectomy surgery after obtaining the legal permission of sex reassignment surgery according to the preexamination tests in Iran. All patients were followed up for 12 months. The probable need for revision surgery was explained for each patient before the surgery.
| Materials and Methods|| |
A 28-year-old GRS candidate was chosen among the patients who have received the legal permission of this procedure in Hospital Complex of Iran. Informed consent and photography were taken for each candidate. The surgery was started under the general anesthesia. Two circular incisions with the diameters of 2.5–3 cm and 4–4.5 cm (depends on the size of the breast which was 75B with body mass index [BMI] of 19 in our case) were created around the nipple areolar complex (NAC). Marking the site of surgery was done, and a schematic drawing of this step is shown in [Figure 1].
De-epithelialization of the space between two incisions with the diameter of 1–1.5 cm was performed. Breast tissue was excised from pectoral muscle fascia by maintaining 1 cm thickness of tissue under the NAC to avoid tension occurrence. It is shown in [Figure 2].
After hemostasis achieved, the closed-suction drain was placed in the area, and purse string was obtained using 4-0 nonabsorbable suture in the borderline of the outer circle of the skin. Finally, the skin and subcutaneous tissue was closed using absorbable suture as shown in [Figure 3].

After dressing up the surgical site, patients must wear compression garment. The drains were removed when the drainage was <30 cc/day. Finally, NAC was examined to evaluate the blood circulation. The follow-up continued for 1 year after the surgery and results were collected by evaluating the satisfaction, scar formation, nipple sensation, and need of revision.
| Results|| |
During 2016–2017, 20 patients underwent sex reassignment surgery using concentric periareolar subcutaneous mastectomy in Imam Khomeini hospital complex in Iran. We monitored our patients for 1 year. Moreover, our findings are as follows:
- Satisfaction: The satisfaction was rated as “very satisfied,” “satisfied,” and “not satisfied.” Among 20 patients, who underwent the GRS in Imam Khomeini Hospital Complex of Iran, 19 of them (95%) were “very satisfied” and “satisfied” from the result of surgery. These data are tabulate in [Table 1]
- Scar formation: After 1 year of surgery, an acceptable scar was remained in the site of mastectomy
- Nipple sensation: We considered sensation score as a quantitative variable varies between 0 and 10 in where 0 and 10 indicates no sensation and good sensation, respectively. This evaluation was done by superficial and deep breast touch by a doctor. After 1 year from the GRS, the average score of nipple sensation was 7.9
- Complications: Hematoma occurred in one patient, and there was no other complication among other patients in our study. Hematoma was managed conservatively
- Need for secondary correction: During 1 year from the surgery, three patients needed revision because of contour deformity occurrence. Liposuction was performed for one of them, and two of them underwent the excess breast skin removal.

| Discussion|| |
Mastectomy in TS people who are the candidates of GRS plays an important role in esthetic purposes to make a male chest with minimal scar. There are many different techniques which are used to achieve this aim.,,,,,,, For smaller breast and elastic skins, the semicircular technique which was first described by Webster is deployed. The resultant scar in this technique is acceptable. In the cases with small breasts and large prominent nipple, the Trans-areolar Technique is used. This procedure allows us to resect a specific amount of nipple, but the result scar on NAC may be remained. In patients with large and ptotic breasts, the free nipple graft technique is preferred.,, Long residual scars, changes in pigmentation, and sensation of NAC and the risk of incomplete graft take are some disadvantages of this method. Because of confining the scar to the circumference of the areola, concentric circular technique has aesthetic results in these patients. This method also allows us to positioning and reducing the areola. A same method called the extended concentric circular technique is used for correcting wrinkling resulted by large difference between the inner and outer circles. The result scar may extend horizontally onto the breast skin. Selecting the proper technique depends on the size of breast tissue and the degree of ptosis. In order to avoid depression deformity, we must save a small amount of mammary tissue. Furthermore, the pectorals major muscle fascia must be preserved to be fixed with fascia. Hematoma should be controlled and supervised during the follow-up.
Subcutaneous mastectomy allows us to conserve the nipple areola skin and gives the surgeon maximum access to the breast tissue. The resultant scars are also acceptable and have aesthetic effects in making male-chest for TS patients who are candidates of FTM GRS.
There are many studies in which subcutaneous mastectomy outcomes are evaluated. In a study by Matton and Anseeuw on 202 patients, the rate of complication was 5%, and the patients who needed secondary corrections of areola, scar, and chest contouring were 8.9%, 12.6%, and 17.8%, respectively.
Cameron et al. studied 97 patients who were candidates of TGS subcutaneous mastectomy with a 5-year follow-up period. Totally, five major complications were reported. Furthermore, there was an indication of some minor complications included hypertrophic scarring, deformities, and pigmentation changes of the nipple grafts.
In the study of Kääriäinen et al., 57 patients underwent the GRS. Chest-wall contouring surgery was performed for these patients and among them, one-third of the patients experienced postoperative complications; 14%, 28%, and 15.8% needed scar, contour, and the nipple corrections, respectively. In this study, the rate of complication occurrence was larger than in ours; and it may have a relation with the method of the surgery.
Eighty-eight patients underwent FTM sex reassignment surgery by Fredrick and his colleagues using subcutaneous nipple-sparing mastectomy technique. Eighty-three patients were satisfied from the results of surgery, and there were no complications. In our study, we experienced complications in three patients, and we need more study to prevent it for the future cases.
Top and Balta reported the occurrence of complications in 13.4% of patients among 52 patients who underwent the subcutaneous mastectomy FTM surgery using Webster semicircular, concentric circular, vertical, and apron flap methods. The rate of complication was 13.4%, and the results showed that all patients were satisfied from the esthetic results of the surgery. They choose the technique of the surgery according to breast size, degree of skin excess, skin elasticity, chest width, nipple areola complex size and position; while in our study, all patients were selected among the patients with average BMI of 21 and average breast size of 78 to perform concentric periareolar subcutaneous mastectomy.
Among 20 patients in our study, 90% of them were satisfied from the results of the surgery; there was only one patient who experienced hematoma, but no necrosis, pigmentation changes in nipple and hypertrophic scar were observed. The scar remained in the site of surgery was acceptable in all patients. During 1 year from the surgery, three patients needed revision because of contour deformity occurrence. Liposuction was performed for one of them, and two of them underwent the excess breast skin removal.
We need more studies to eliminate the complications of this surgical technique and also, evaluating the various aspects of subcutaneous mastectomy methods.
| Conclusion|| |
Concentric periareolar mastectomy is probably a good technique of subcutaneous mastectomy in FTM GRS. That is because of giving the surgeon maximum access to the breast tissue and possibility of repositioning and reduction of nipple areola complex. Furthermore, the result scar in this method is acceptable and gives the patients a good feeling of having a male chest. The elimination of postoperative complications and scar formation needs the experience of a plastic surgeon. Finally, it should be considered that choosing the proper method of surgery is a critical step in these patients and it may help us to prevent the occurrence of complications postoperatively. Our study was performed in Imam Khomeini Hospital Complex of Tehran, Iran.
