ANATOMY (Fig. 58-1)

Skin: The skin covering the shoulder and arm is smooth and very mobile over the underlying structures.


It is thin on medial aspect and progressively thicker laterally.


Subcutaneous tissue: Fat accumulates on the inferoposterior aspect of the arm, with a minimal amount medially.


Superficial fascia: The superficial fascia both circumferentially and longitudinally encases the fat of the arm from the axilla to the elbow.


This fascia weakens with age and weight gain, causing ptosis of the posteromedial arm.


Deep fascia: The deep fascia invests all muscles and important neurovascular structures.


This layer should never be violated during brachioplasty or suction-assisted lipectomy.



TIP: Along the distal third of the arm and in the region of the medial elbow, the basilic vein and medial antebrachial cutaneous nerve run together and are superficial to the deep fascia and vulnerable to injury, especially where they pierce the deep fascia an average of 14 cm proximal to the medial epicondyle.1



TIP: The only nerves found superficial to the deep investing fascia are branches of the medial brachial cutaneous nerve and the intercostobrachial nerve. All other important neurovascular structures are deep to the investing fascia.


PREOPERATIVE EVALUATION


Obtain a complete medical history, paying specific attention to weight gain/loss, weight stability, tobacco use, and scarring.



TIP: Weight should be stable for 6-12 months before performing any body contouring procedure on a massive-weight-loss patient.


Physical examination should focus on the amount of excess skin, excess subcutaneous tissue, and degree of ptosis present in the arm.


Patients can then be stratified into one of three groups (Table 58-1).

An algorithm (Fig. 58-2) can then be used to help guide surgeons to the procedure that is best suited to achieve optimal results.2

INFORMED CONSENT


Patients need to be informed that, with a brachioplasty, they are trading a more pleasing shape and contour of the arm for a scar.


The scar is not inconsequential and will be visible depending on the type of clothing worn.


Scars may stay thick and heavy for a prolonged period of time.


The brachioplasty scar is likely the most noticeable scar in all of aesthetic surgery.




TIP: Photographs are imperative when discussing brachioplasty outcomes.


Common brachioplasty complications include widened hypertrophic scar, wound dehiscence, seroma, infection, paresthesias/numbness, scar tethering across the axilla, and recurrent skin laxity.


EQUIPMENT


No special equipment is needed to perform a brachioplasty unless concomitant liposuction is performed.


In this case, wetting solution and liposuction equipment are required.


TECHNIQUE


MARKINGS


An area of debate for surgeons performing brachioplasty is where to place the arm scar.


Many place the scar within the brachial groove, whereas others prefer a posteriorly positioned scar.


A survey of plastic surgeons and the general public showed that a medial, straight brachioplasty scar is more acceptable than a posterior straight scar.3


Brachioplasty markings depend on the type of brachioplasty performed.


The type of brachioplasty performed depends on the location of the excess skin (see Table 58-1).


Type I: Minimal skin excess, moderate fat excess


If skin tone is good, this is best treated with suction-assisted lipectomy alone.


Type IIA: Moderate proximal skin excess, minimal fat excess


A minibrachioplasty4 is used, which is isolated to the axillary fold.


If the skin excess is purely horizontal, then a vertically oriented wedge or ellipse is placed in the axillary fold (Fig. 58-3, A).

If skin excess is horizontal and vertical, a T-shaped excision is used (Fig. 58-3, B).


Type IIB: Moderate skin excess of the entire arm (axilla to elbow), minimal fat excess


A traditional brachioplasty is used placing the scar in the brachial groove.


If there is vertical skin excess only, then use a linear horizontal incision (Fig. 58-4, A).

If there is vertical and horizontal skin excess, add an L-shaped extension to the linear horizontal incision in the axilla (Fig. 58-4, B).


Type IIC: Moderate skin excess of the arm and chest, minimal fat excess


An extended brachioplasty is needed, which extends the excision onto the chest wall.


These are typically massive-weight-loss patients.


A horizontal incision is made in the brachial groove and carried through the axilla down onto the chest wall.


This excision often passes distal to the elbow (Fig. 58-5).
