24 Advanced Techniques forButtock Restructuring, Reshaping, andLifting
327
In the latter, a vertical midline incision of approximately 6–7cm in length is made above the intergluteal crease, depending on the size of the implant and the patient’s buttock dimensions. Subsequently lateral dissection of approximately 5–6cm is performed with electrocautery at the level of the suprafascial space trying to preserve the fascia of the gluteus maximus muscle, and then blunt dissection of the muscle bers is performed with metzembaum scissors. This is done following the direction of the muscle bers, which are not sectioned, they are only separated. After this, the dissection of the intramuscular pocket is performed, for which a series of blunt dissectors are used (Fig. 24.4); these are used sequentially until obtaining a pocket of adequate dimensions. When dissecting the pocket, it is impor­tant to try to preserve an adequate muscle thickness (usually about 2–3cm) in both portions of the pocket, that is, the muscle thickness must be similar in the pocket walls to obtain adequate coverage above the implant and to get coverage of neuro­vascular structures under the implant.
Once the pocket is made, the hemostasis is veried, irrigation of the cavity with saline solution and antibiotic application is performed both in the intramuscular pocket and on the implant, an anatomical gluteal implant is placed, being generally small to moderate in size, which will depend on the dimensions of the bony frame­work of the patient. Once the implant is placed, a 4mm Jackson Pratt drain is placed in the base of the pocket and then the closure is performed, rst of the muscle tissue with separated stitches of vicryl 2/0; once closed, the subcutaneous tissue is left open in order to perform the lipoinjection through this access, which is performed subcutaneously, mainly in the central region of the gluteus to provide more projec­tion, in the peri-implant area to create a smooth transition between the implant and the surrounding tissues and in the gluteal framework, in addition to combining with liposuction of the surrounding areas if necessary. By performing lipoinjection in the subcutaneous plane, the risk of damaging the implant is totally avoided, since the implant was placed in the intramuscular plane. The compound technique is an excellent resource in thin patients, in which we would get an unsatisfactory result if we only performed lipoinjection (Fig.24.5).

24.5 Buttock Lifting by Lipectomy in“Wings ofSeagull”.
In older patients, patients with poor skin quality, overweight, or with a history of weight loss, it is common to observe different degrees of skin laxity and sagging, as well as gluteal ptosis (Fig.24.6a). In this type of patients, lipectomy is usually per­formed in the form of “seagull wings.”
This is the technique that I most frequently use in gluteal contour surgery. In my 25years’ career, I have observed that the only way to achieve a signicant buttock lift in this type of patients is by performing cutaneous excision and repositioning of the buttock. This technique allows to reshape the buttock and the surrounding frame in the way that I want, managing to place the buttock in an adequate position, rais­ing it as much as desired, in addition to allowing to modify its dimensions, shorten­ing or lengthening it according to the needs of the patient (Fig. 24.6b). The modication of the length of the buttock will depend on the site where the lower segment of the lipectomy is placed, the modication of the buttock’s width is also possible, widening by lipoinltration or narrowing its dimensions by performing liposuction; with this technique we can give the buttock as much projection as desired by lipoinjection and/or implant placement according to the need and desire of each patient.

Fig. 24.7 (a, b) Double buttock deformity: refers to an accumulation of fat in the inferomedial quadrant of the buttock
E. U. Góngora Alejandre and C. C. Solis López
Frequently, especially in patients who are overweight, with antecedent of weight loss and gluteal ptosis, we observe what I have called “the double buttock defor­mity,” (Fig.24.7) which is an accumulation of fat in the inferomedial quadrant of the buttock, lateral to the intergluteal crease and above the infragluteal crease; this “double buttock” gives a ptosic, aged, and irregular appearance. It is important to perform lipoaspiration of this fatty tissue and to reshape the periphery of this region through lipoinjection to achieve an aesthetic and regular contour.
24.5.1 Markings
This type of surgery is regularly performed in conjunction with a tummy tuck, that is, a circumferential abdominoplasty is performed and the incisions of the “lipec­tomy in seagull wings” are continued with the incisions of the tummy tuck.
The position of the lower incision of the lipectomy will be determined by the length that is desired to be given to the buttock, in case of having a short buttock, the incision will be placed more cephalic to give it greater length. If we have a very long buttock, we will place the incision lower in order to make the buttock look shorter (Fig.24.8a).
Usually this is an area in which it is difcult to perform a pinch test unless the patient has a history of a massive weight loss. If possible, the amount of tissue to be resected is determined by performing a pinch test; however, in most patients this is a zone of adherence and in many cases this is not possible. In order to determine the point at which the upper incision will be made is by means of a maneuver in which gluteal traction is performed simulating the lifting that is desired to achieve with the surgery. In this way it is determined the point at which the buttock will be xed to and where the placement of the incision is planned (Fig.24.8b).

24.5.2 Surgical Technique
With the patient in the ventral decubitus position liposuction of the areas to be treated is begun in the manner previously described, performing tumescent inltra­tion to minimize bleeding, the fat graft harvesting is performed with the “minimal fat exposure technique” described previously. In case we are only performing but­tock augmentation by lipoinjection, this is done immediately.
Subsequently, with scalpel, the incision of the lipectomy in “seagull wings” is made going through planes, making a section of supercial and deep fascia until we reach the thoracolumbar aponeurosis. At this level it is important to preserve a layer of deep fascial tissue to preserve the lymphatic ow of the area and decrease the presence of postsurgical seromas. We perform exhaustive hemostasis with electro­cautery nishing the resection of the aps according to the surgical plan. After per­forming the buttock augmentation and the resection of the aps of the lipectomy, washing and irrigation with saline is performed to eliminate cellular debris and impurities of the surgical material such as cloth bers, talcum powder from gloves, etc. (Fig.24.9). We apply rifamycin in the area and nally two closed drains are placed, a Jackson Pratt of 10mm and a drenovac of ¼ inch. To perform the closure of the lipectomy we start at the level of the midline, performing closure of super­cial and deep fascia with vicryl 1 and making an anchorage to the thoracolumbar

fascia. This anchor point is of paramount importance to achieve an adequate reposi­tioning of the buttocks; as we advance laterally with the closure of the wound, it is important to perform adequate compensation and xation of aps to achieve ade­quate tissue distribution and thus avoid excessive remnants at the lateral level. Subsequently deep dermal closure is performed with continuous vicryl 2/0 stitches and we end closure with an intradermal suture with nylon 2/0. At this point the but­tock restructuring surgery has been completed and the abdominal lipectomy is con­tinued (Fig. 24.10). With this technique we can get excellent, consistent and long-lasting results (Fig.24.11).

24.6 Buttock Lifting by “Lipectomy inSeagull Wings” +
Placement ofButtock Implants
When performing this technique, liposuction is performed in the manner previously described, the difference is that the fat graft obtained is similarly decanted within the same Tummy syringe, but is reserved in a sterile container for later use. The incision of the lipectomy is made in in the manner already described and after com­pleting it, the same approach is used to perform the placement of the implants. The gluteus major muscle bers are located, the blunt dissection is performed, and the formation of the intramuscular pocket is made in the manner already described, the implant and the drains are placed, and the closure of the intramuscular pocket is performed with vicryl 2/0, leaving the subcutaneous tissue intact in order to perform the lipoinjection in the peri-implant area and in the entire buttock framework accord­ing to the surgical plan. This technique is reserved for patients who desire a very signicant increase in the dimension of the buttocks, or very thin patients with dif­ferent degrees of ptosis and sagging tissues (Fig.24.12a–d).
