Comma-Shaped Incision for Reduction Mammoplasty and Mastopexy
1Department of Plastic, Reconstructive and Aesthetic Surgery, Nippon Medical School.
Objective:
Various skin incision methods have been reported for reduction mammoplasty and mastopexy. This report describes a new incision method that may improve on conventional methods, particularly with respect to prevention of hypertrophic scars.
Methods:
We developed a comma-shaped incision method that results in fewer scars and less strain on the suture line. We then applied this new method to two cases, namely, one case of breast reduction and one case of breast fixation.
Results:
In both cases, we achieved good results. There was no scar at the inframammary fold, and no hypertrophic scar formation. All scars were within the breast area and were not in contact with the brassiere wire; hence, there was less pain after the operation.
Conclusions:
We developed a new incision method for reduction mammoplasty and mastopexy.
