CHAPTER 33 Periareolar V-T Parachute Mastopexy
Key Points
Historical Background
The term ‘periareolar scar’ refers solely to the site of the scar, but omits any mention of the technique used on the neighboring tissue. This idea is not new, since already in 1952 Gillet1 described a ptosis correction technique involving implantation of nylon mesh around the nipple by suspending it from a narrow cloth band looped around the clavicle. But the author also states that it is difficult to perform a satisfactory cutaneous resection using this method and terminates with a Biesenberger T scar2 in cases where extensive cutaneous resection is required. A number of authors have also used this circular approach, which involves solely an intra- or periareolar incision without insertion of a foreign body. For example Andrews3 advocates an L-shaped resection in the lower outer quadrant secondary to complete dissection of the dermis. This cleavage, which reduces the vascular network of both the skin and breast tissue, explains why the resection in such cases is inevitably of limited scope. For mastopexy, Andrews dissects and plicates the lower extremity of the breast. Following resection of a small strip of skin around the initial intra-areolar incision, the incision is closed in such a way that the cutaneous envelope wraps itself back around the reshaped breast. However, this method is indicated solely in the presence of minor hypertrophy or ptosis and good skin elasticity, and follow-up of the results shown in the illustrations has been unduly brief (1, 2, and 3 months). Benelli4 de-epithelializes a far larger periareolar area, remodeling the adjacent region using glandular flaps, thus incurring a risk of devascularization if resection and dissection are unduly extensive. However, in such settings it is essential to achieve breast projection since periareolar techniques tend to diminish it (assuming of course that shaping the gland alone has a lasting effect). If this (or any other) periareolar technique is performed inadequately or on fatty breasts, a flattened, donut-like appearance is obtained. What should be performed instead is a periareolar circle using robust, non-resorbable sutures, since this is the only type of material that can conserve the incongruence between the two areolar circles and thus avoid excessive areolar enlargement. Felicio5 shifts the site of the resection to the periphery of the breast, with a view to conserving a central pedicle, and likewise uses non-resorbable sutures to maintain the size of the areola. This technique yields the most satisfactory result in younger patients whose skin exhibits good elasticity, and for resections amounting to an average of 300 g per breast (although exceptions to this rule are altogether possible). However, such procedures may be associated with unsatisfactory breast projection, suboptimal scar quality, and areolar enlargement, as well as a risk of areolar necrosis in cases where extensive and multiple resections are performed in the various quadrants.
Other authors have attempted to remedy the main shortcoming (i.e. deficient breast projection) by inserting a net between the skin and breast tissue with a view to creating and maintaining a conical shape. Bustos6 partially encircles the breast with silicone mesh, but only partially, so as to allow for expansion during pregnancy. However, Sampaio Goes7–9 has achieved the most impressive cosmetic and reconstructive surgery results in remodeling the breast following lumpectomy, via the most promising technique of all. This involves the use of resorbable netting, then taking maximum advantage of dermal spreading, and finally the deployment of partially resorbable netting.
The V-T Parachute Technique Principles
This technique aims to combine the advantages of the methods described above with a new approach to resection that is closely related to breast remodeling and avoids the use of a foreign body. Instead of interposing netting, I perform extensive de-epithelialization with a view to achieving the vascular efficiency afforded by the dermis and advocated by Lalardrie (this is also the most innovative feature of his dermal vault technique10).
