Prep: neck to umbilicus Measure defect Blood supply: pectoral branch of thoroacromial artery(2ND DIV OF THE AXILLARY ARTERY), and less important supply from the lateral thoracic artery—KEEP INTACT IF A SHORT FLAP (PHARYNGEAL CLOSURE) Nerve Supply: lateral pectoral nerve(located medially and runs with pectoral branch of the thoracoacromial artery), and medial pectoral nerve (located laterally) Origins: 1)medial one half of clavicle, 2)sternocostal from manubrium and body of the sternum and 1st or 2nd to 6th costal cartilages, 3)abdominal from the rectus fascia Insertions: crest of the greater tuberosity of the humerus. Skin and underlying rectus fascia which is used distal to the muscle and pedicle vessels is called the “random portion”, the remainder of the flap is “axial” 1. Mark out intercostal spaces 1-6.—PLACE A 4′ X 4′ AT (WITH THE SUP EDGE) THE INF BORDER OF THE CLAVICLE—THE INF EDGE OF THE 4′ X 4″ = THE SUP EDGE OF THE SKIN PADDLE 2. Draw planned flap medial to nipple (if possible), begin at intercostal space 4 and go inferiorly.—PALPATE THE MUSCLE 3. Incise through skin and subcutaneous tissues down to level of pectoralis fascia– NOT into muscle. Round corners of incision. DON’T undermine flap—ACTUALLY BEVEL OUT A BIT. 4. Tack pec fascia to dermis with 3-0 BIOSYNl OR VICRYL sutures. 5. Make incision from upper, outer corner of skin paddle to axilla–roughly parallel to clavicle–and incise down to pec fascia. 6. Use skin hook to hold upper flap and #10 scalpel to elevate at fascia level-TAKE FASCIA UP—leave no fat down but don’t cut into muscle. Continue elevating to clavicle. Enter neck and open up until can easily fit a hand through over clavicle. BEWARE OF CEPHALIC VEIN IN THE DELTOPECTORAL GROOVE! 7. Elevate lower flap in same fashion., identify clavipectoral fascia laterally, identify inferolateral border of pectoralis major muscle and elevate it off
of the pectoralis minor and chest wall. DO NOT BOVIE ON THE CHEST WALL! WATCH for perforators. PEC MINOR MORE VERTICALLY ORIENTED—FROM THE CORONOID PROCESS OF THE SCAPULA—-UNDER A DISTINCT LAYER OF FASCIA 8. Come around inferior aspect of muscle island and cut medially with Mayos to elevate muscle off chest wall–don’t undercut flap under skin. 9. Elevate muscle off chest wall continuing superiorly–identify pedicle on undersurface of pectoralis major muscle—ABOUT 2/3 OF THE CLAVICLE OUT. CAN VISUALIZE AND PALPATE THE PEDICLE—BEWARE OF THE CEPHALIC VEIN! Continue dissection to clavicle 10. Keep a finger on the pedicle and divide laterally the humeral attachments to help rotate flap over clavicle, try to preserve the lateral thoracic artery located in this area STICK FINGER UNDER AND AROUND HUMERAL ATTACHMENTS AND BOVIE TO FINGER STAYING AS LAT AS POSSIBLE.. 11. The medial one half of the clavicle can be resected if more length is needed 12. Avoid twisting the muscle to avoid occlusion of the pedicle vessels. 13. Close chest wound primarily using 2-0 vicryl and staples, Two JP drains should be used in the chest. —SEW SKIN PADDLE IN WITH 3-0 BIOSYN 14. No tight ties around the neck.
