PREOPERATIVE DIAGNOSIS: Mass, right breast.
POSTOPERATIVE DIAGNOSIS: Mass, right breast.
OPERATIVE PROCEDURE: Right breast mass excision.
PROCEDURE: With the female patient under general anesthesia, the breast and chest were prepped and draped in a sterile manner. An elliptical incision was made in the central portion of the breast about the palpated mass, including the area of the nipple. This was excised all the way down to the fascia of the breast and then submitted for frozen section. Frozen section revealed a carcinoma of the breast with what appeared to be a good margin all the way around it. We then maintained hemostasis with electrocautery and proceeded to close the breast tissue using 2-0 and 3-0 chromic. The skin was closed using 4-0 Vicryl in a subcuticular manner. Steri-Strips were applied. The patient tolerated the procedure well and was discharged from the operating room in stable condition.

The medial aspect of the flap was elevated excising the old scar in the process, and the flap was elevated to about 60% of its extent to include all of the redundant fat that was within the flap. We removed about 1.5 cm thickness of flap from the bottom of the flap and left a layer of padding of about a cm on the bed. Hemostasis was secured, and then we closed the wound with a combination of plain 3-0 Prolene and horizontal mattress sutures and some horizontal half mattress sutures of 3-0 Prolene. We dressed the wound temporarily with Kerlix and Kling. Dr. Miller will then proceed with his portion of the procedure.
