About

Over the past 10 years, there have been substantial improvements in breast reconstruction by plastic surgeons, and much has been achieved in aesthetic restoration after mastectomy. Advances in both microsurgery and implants have allowed for a wider variety of surgical methods, and procedural skills that minimize donor site complications have been developed.

With such satisfactory aesthetic results, interest has recently increased not only in breast reconstruction but also in sensory recovery. Due to the growing expectation of patients, sensory discomfort may decrease overall patient satisfaction with breast reconstruction despite good aesthetic results. Hence, for qualitative improvement of breast reconstruction surgery, efforts must be made to restore sensation in the reconstructed breast. There has been little research on the mechanism of sensory recovery despite its clinical importance. This study aimed to compare the degree of sensory recovery in the reconstructed breast using various reconstruction methods as well as to evaluate the status of neural regeneration with harvesting the tissues when nipple reconstruction is performed.

Enrollment: 50 estimated patients

Sex: Female

Ages: 20+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Female adults over 20 years of age
• Patients who have undergone or plan to undergo total mastectomy and immediate breast reconstruction after the diagnosis of breast cancer (including carcinoma in situ)
• written consent to study participation

Exclusion criteria

• presence of neuropathy that may hinder accurate assessment of sensation
• presence of dermatological condition that may hinder accurate assessment of sensation
• inability to provide written consent

Trial design

50 participants in 2 patient groups

Reconstruction using an implant

Description:

Immediate 2 stage implant based breast reconstruction after mastectomy. All expanders are placed in the subpectoralis muscle using ADM as a sling. After expansion of the tissue expander change to the permanent implant is performed.

Reconstruction using abdominal tissue

Description:

immediate free DIEP flap breast reconstruction after mastectomy. DIEP(deep inferior epigastric perforator) free flap was prepared and transferred to the breast pocket. Microanastomosis was done under the microscopic magnification. On sitting position, free flap was inset into breast pocket with confirming of satisfactory inflammatory fold.
