MODIFIED RADICAL MASTECTOMY
Operative
Technique:
Patient
supine under General Anesthesia
Ipsilateral
arm abducted from axilla
Pad
placed underneath patient’s scapula and posterior hemithorax
Asepsis
and antisepsis technique
Sterile
drapes placed
Elliptical
incision made encompassing mass with 3-5cm margin together with the
nipple-areola complex. Depth of incision carried from skin through subcutaneous
tissue.
Towel
clips applied to edge of skin on flap about 2 – 3cm apart
Ask
Assistant to elevate skin flap by drawing towel clips upward making it
perpendicular to the breast tissue while applying countertraction by depressing
breast.
Dissection
carried out by use of electrocautery incising cooper’s ligaments which
attach breast to subcutaneous tissue
Skin
flaps extended: Superiorly – subclavius muscle; Medially – sternum;
Inferiorly – about 2 – 3 cm inferior to the inframammary fold;
Laterally – anterior border of the latissimus dorsi
From
the sternum to the lateral margin, fascia incised with the use of
electrocautery overlying pectoralis major muscle. Bleeders either
electrocoagulated or suture-ligated.
At
the lateral margin of the pectoralis major elevate the edge of the pectoral
muscle from its investing fascia using blunt and sharp dissection maintaining
continuity between the breast, the pectoral fascia, and the lymph nodes of the
axilla
Pectoralis
minor preserved
Axillary
vein identified, adventitial sheath incised
Level
I and II axillary nodes and Rotter’s nodes removed
Thoracodorsal
and long thoracic nerve identified and preserved
Copious
saline irrigation
Hemostasis
Complete
sponge and instrument count
Closed-suction
drain placed laterally and medially and positioned in the inferior flap
Subcutaneous
tissue approximated with vicryl 2.0 sutures
Skin
closed interruptedly with silk 3.0
Drain
secured with silk 2.0 sutures
Fluffy
dressing applied
