Axillary Aug Video Clip Legends Clip 01: Roaming and zoom capabilities of a mobile endoscope. Using the retractor to establish exposure, the surgeon can roam the pocket and zoom in and out by holding the endoscope in the non-dominant hand separate from the retractor. Clip 02: Division of pectoralis major muscle origins along the inframammary fold. With the retractor positioned at the junction of the inframammary fold medially with the sternum, the surgeon uses the Probe Plus II needlepoint dissector in a light, sweeping motion to divide pectoralis origins 1 cm. above the desired inframammary fold. The surgeon divides pectoralis muscle and deep subcutaneous fascia to expose subcutaneous fat. Clip 03: Division of pinnate pectoralis origins medially, preserving all of the main body of muscle origins along the sternum intact. With the retractor at the 3 o’clock position of the right implant pocket medially, the surgeon uses the needlepoint electrocautery to dissect through the filmy areolar tissue and expose the medial origins of the pectoralis along the sternum. The surgeon can safely divide pinnate origins of the pectoralis that are lateral to the main body of pectoralis origins (these origins often have a tendinous appearing attachment to the ribs, illustrated by the muscle origin in the center of the frame). The surgeon should never divide the main body of pectoralis origins along the sternum, even partially, to avoid compromising critical medial soft tissue coverage and to prevent uncorrectable implant edge visibility and visible traction rippling. Clip 04: Mid pocket to lateral pocket dissection. With previously divided muscle origins in view at left, the surgeon divides pectoralis major origins off the 4th and 5th ribs to transition from the 7 to 10 o’clock position into the lateral portion of the right implant pocket. Dividing muscle origins slightly off the rib surfaces optimizes hemostasis. If the surgeon cuts muscle origins flush with the ribs and intercostal musculature, intramuscular vessels can retract, bleed, and be more difficult to control. Clip 05: Mid pocket to lateral pocket transition With the retractor at the 7 o’clock position of the right breast pocket, the surgeon sweeps from medial to lateral to transition from medial to lateral pocket dissection. Clip 06: Lateral pocket dissection Positioning the retractor at the 9 o’clock position of the right breast pocket and twisting the retractor tip laterally exposes the lateral border of the pectoralis minor muscle and places tension on the lateral breast soft tissues to provide optimal exposure. The surgeon incrementally sweeps the needlepoint electrocautery dissector tip parallel to the lateral border of the pectoralis minor to enlarge the lateral pocket, using light, sweeping strokes to incise the tissue in small increments for optimal control. Maintaining tension by twisting the retractor laterally places lateral intercostals nerve branches under tension to make them more visible during lateral pocket dissection. Clip 07: Checking cut muscle edges for hemostasis With the retractor in one hand, and the endoscope in the other hand, the surgeon sweeps from medial to lateral to examine all cut edges of the pectoralis muscle for intramuscular vessels to assure optimal hemostasis and avoid even minor bleeding that leaves blood in tissues, increasing inflammation and patient discomfort.
