Thank you for the question. Although difficult to give you a precise percentage, my best estimate would be less than 5% of patients undergoing surgery for gynecomastia benefit from revisionary surgery. These revisionary operations may help with the appearance of scars, to correct asymmetry if possible, to remove additional breast tissue and/or adipose tissue, and correction of over resection/ concavity deformity. As always, prevention of complications as much as possible is preferable; patients seeking this type of surgery should consult with well experienced board certified plastic surgeons. I hope this helps.
Dear patient, It is not unusual to have a revision following a male breast reduction surgery. Although the revision should not be done earlier than 6 months post your surgery.
