Gynecomastia is a condition commonly associated with puberty. An endos
cope-assisted transaxillary procedure was used to treat a patient with
this condition. An endoscope system was inserted into a 4-cm skin inc
ision in the axilla, and the glands and adjacent fat were removed en b
loc. The resulting scar in the axilla was small and inconspicuous, and
the postoperative breast contour satisfied the patient. The endoscopi
c system provided a useful transaxillary approach. These results show
that this method appears to be the most suitable one for surgical mana
gement of gynecomastia.
