Background:
Although transaxillary breast augmentation (TBA) is a well-studied procedure, few previous reports exist concerning the subfascial technique, especially without endoscopic assistance. This study aimed to analyze the feasibility of the technique after breast augmentation in terms of its indication, surgical technique, limitations, and clinical outcome.
Methods:
For this study, 42 patients underwent TBA without endoscopic assistance. The technique was indicated for patients with breasts of small or moderate volume without ptosis, patients who wanted no breast scars, and patients who had a poorly defined inframammary fold. The mean follow-up period was 16 months. Implant and incision approach complications were evaluated. Information on patient satisfaction was collected.
Results:
A total of 14 complications occurred in 42 patients, all of them minor. Axillary incision-related complications occurred in 26% of the patients, as represented by a late axillary subcutaneous band (119%), sensory loss in the inner aspect of the arm (71%), and a hypertrophic scar and small wound dehiscence (71%). No patient presented with capsular contracture, visible rippling, or infection. Most of the patients (93%) were either very satisfied or satisfied with their result, and none regretted the surgery.
Conclusion:
The TBA procedure without endoscopic assistance is a simple and reliable technique for breast augmentation. Most of the complications in this study were minor and predictable. They did not interfere with the aesthetic outcome nor the normal postoperative recovery. With TBA, success depends on patient selection as well as careful intra- and postoperative management.
