using the superior curved incision with convexity downward (Fig.8.3a). Also the incisions are extended beyond the pubis on the lower abdominal sulcus according to the amount of skin to be resected in each case, without umbilical incisions (Fig.8.3a). The superior markings are curved in direction to the ank regions to permit more skin resection (Fig.8.3a). The supercial fascia and the most important anatomical structures will be preserved in the two lateral regions, and in the central area, the skin will be resected up to the rectus fascia muscle, permitting safe plication and reducing the amount of tissue to be preserved in the lower abdomen, improving the aesthetic results (Fig.8.8). In most of the cases, one transversal strip of the pubis is resected to maintain its length to about 6 to 7cm (transversal pubectomy), avoiding higher scars. The navel is dissected from the abdominal wall as performed in mini­lipoabdominoplasty. Plication on the superior abdominal muscle fascia is performed with reduced undermining preserving the abdominal myocutaneous perforating vessels and continues up to the pubis approaching the two preserved supercial fascia segments (Erfon and Mauricio 2016). After the muscle plication, both lateral segments of the preserved supercial fascia (Scarpa’s fascia) are sutured together with 3-0 colorless mono-nylon in the lower abdomen. After this suture, there is no dead space and there is no necessity of drains. Liposuction in the ank areas can be performed as the same surgery using a special position described by the senior author, avoiding prone position. After the nal sutures, a complementary liposuc­tion is carried out to improve the aesthetic results.
Avelar (1999) described the use of liposuction associated with mini­abdominoplasty on the whole abdominal wall and anks, with skin resection on the pubis and on the sub-mammary groove, preserving the abdominal muscle cutaneous perforating vessels in the upper abdomen and the supercial fascia in the whole lower abdomen without panicle undermining. Joining two great techniques in one new idea publishing new concepts to the classical abdominoplasty, starting a new era in the abdominoplasty approach (Avelar 1999).
Saldanha (2001) introduced the lipoabdominoplasty technique associating super­cial and deep liposuction in the whole abdomen with skin resection from the pubis to the umbilicus (full lipoabdominoplasty) preserving the abdominal muscle­cutaneous perforating vessels and the lymphatic system, concluding that this approach reduces the complications and improves the aesthetic results compared to the traditional abdominoplasty technique (Saldanha etal. 2001).
The preservation of the whole supercial fascia and the important anatomical structures in the lower abdomen as recommended by Avelar (1999, 2002) and late by Saldanha (Saldanha etal. 2001) is important to avoid seromas and also is a sec­ondary vascularization as described by Erfon (2001, 2002, 2009, 2011; Erfon and Mauricio 2016) and Almeida (Almeida etal. 2016). The connection of this vessels with their deep homonyms is an important accessory vascularization especially in the cases of mid- and mini-lipoabdominoplasty (Erfon and Mauricio 2016) late con­rmed by Barcelos (Barcelos etal. 2017). It is also important the resection of the central area of the lower abdomen up to muscle fascia permitting a safe plication (without a risk of penetrating the abdominal cavity) and reducing the amount of tis­sue to be accommodated, improving the aesthetic results as published by Erfon (2001; Erfon and Mauricio 2016).

Illouz (1980) described the possibility of treatment of lipodystrophies in the body contour using the technique named liposuction, changing concepts about aes­thetic plastic surgery in the whole body regions (Illouz 1980). Illouz (1992) also published a technique of abdominoplasty without undermining and liposuction in the upper abdomen with skin resection in the lower area to be used on obese patients (Illouz 1992).
Stuckey (1979) used for the rst time the term “midabdomen abdominoplasty” to describe a surgery with skin resection using a transverse incision involving the umbil­ical region. “The skin was undermined above, below, and on both sides” and “the excessive skin was excised transversely as an ellipse” with local anesthesia to avoid a traditional abdominoplasty (Stuckey 1979). The senior author has been using the term mid-lipoabdominoplasty to describe a new approach since 2001 (Erfon 2001). The indications are the special cases where it’s impossible to pull down the superior abdominal ap and needs more skin resection than in mini-lipoabdominoplasty.
The markings described by the senior author dividing the lower abdomen into three segments, permitting the preservation of the supercial fascia and the whole impor­tant anatomical structures on both lateral segments and the resection of the central segment up to the muscle fascia, below the umbilicus, permitting a safe plication was named by Avelar (2016a) a set contribution to the lipoabdominoplasty technique.
Uebel (1994) recommended a smaller detachment of the tunnel for plication, reducing the complications such as seromas and preserving nerves and vasculariza­tion from the anks (Uebel 1994). The same author (2009) published that the inci­sions start in the supra-umbilical area and go to the xiphoid appendix through a narrow tunnel for plication and also recommends to place the patient in the Fowler position to pull down the superior abdominal ap and test the appropriate skin resection before the inferior incisions are carried out (Uebel 2009).
Pontes (2004) recommended the geometrical inferior skin ap block resection (Pontes 2004). The senior author has been performing the skin resection in the lat­eral areas of the lower abdomen after liposuction preserving the supercial fascia.
Hakme (1983) published his contribution to abdominoplasty technique using a peri- and supra-umbilical lipectomy from the navel to the xiphoid appendix produc­ing a resultant depression in this central region and natural aspect. He also recom­mends a diamond shape to the umbilicus (Hakme 1983).
Ishida (2011) analyzed the strength of different abdominal fascia in different sutures used in abdominoplasty and concluded that the vertical suture is more resis­tant than the horizontal due to the distribution and arrangement of muscle bers (Ishida etal. 2011). Since the beginning, the senior author has recommended the “X” separated stitches using mono-nylon 0 (zero) from 1cm above the xiphoid process to the pubis (Erfon 2011; Erfon and Mauricio 2016). Also the plication of the supercial fascia in the lower abdomen is carried out using 3-0 colorless mono­nylon with the following advantages: there is no dead space or necessity of drain and the seromas and the length of the nal scars are reduced (Avelar 1999; Saldanha etal. 2001; Erfon and Mauricio 2016).
Baroudi (Baroudi and Ferreira 1998) introduced internal stitches xing the abdom­inal ap to the abdominal wall reducing the dead space and also the seroma, an impor­tant contribution to the abdominoplasty technique (Baroudi and Ferreira 1998). When

the supercial fascia is preserved in the lower abdomen associated with small under­mining of the tunnel for plication, these kinds of stitches are not necessary.
Koller (Koller and Hintringer 2012) concluded with anatomical study that the supercial fascia preservation prevents seromas (Koller and Hintringer 2012), as recommended by the senior author and others (Erfon 2002; Avelar 2002; Barcelos etal. 2017).
Caprini (2005) recommends a low molecular weight heparin, 40 mg/day for 10days, to reduce thrombotic events (Caprini 2005). The senior author uses this protocol to all his patients and phlebopressor on the legs during their hospitalization and early de-ambulation (Erfon and Mauricio 2016).
Faria-Correa (1992) published the possibility of a video-endoscopic approach to perform muscle plication, reducing the scars in cases of mini-abdominoplasty (Faria-Corrêa 1992). This was also suggested late by Avelar (1999).
Nahas (2001) published an objective classication based on subcutaneous and skin deformities (Nahas 2001), allowing scar above the pubis line, in its type II.The senior author inverted the incision convexity in his Group 3 to avoid high scars.
Faria-Correa (2016) also introduced the possibility of plication of the rectus abdominis muscle using robotic approach, permitting a minimally invasive surgery associated with minimal incisions at remote sites (Faria Correa 2016).
Bozolla (Bozolla and Psillakis 1988) published important new classication of abdominoplasty deformities in ve types and indication of surgery for each type (Bozolla and Psillakis 1988). The senior author classied his patients into four groups with his respective surgical indications.
Avelar (2016a, b) drew attention to the anatomical principles of his technique giving special attention to the description of the vascularization of the skin and musculoaponeurotic wall and his classication of abdominoplasty in order to improve a safest abdominoplasty (Avelar 2016b).
Yacoub (2016) published the extended reverse abdominoplasty in which a com­plete abdominoplasty is performed with a transversal sub-mammary incision and extended dissection of the skin ap up to the pubis region using in special cases the ap to breast reconstruction (Yacoub 2016). This approach was performed by senior author in rare cases.
Hunstad (Hunstad and Jones 2011) recommends the circumferential body lipo­suction associated with abdominoplasty with tumescent inltration (Hunstad and Jones 2011).
Graf (2006) using Doppler published important evidence that abdominoplasty with small undermining and preserving the abdominal myocutaneous perforating vessels reduces complications such as necroses and seromas (Graf etal. 2006).
Barcelos (2017) published a study showing 86.7% reduction in the rate of seroma when comparing lipoabdominoplasty with classical abdominoplasty (Barcelos etal.
2017). The senior author also described the importance of the supercial fascia
preservation and the reduction on the rate of complication such as skin necrosis and seroma and secondary liposuction in the lipoabdominoplasty compared with tradi­tional abdominoplasty technique (Erfon 2002, 2009, 2011; Erfon and Mauricio 2016).

Conclusion
The senior author concludes that lipoabdominoplasty was a great evolution to the abdominoplasty technique in the last 60years. Joining two great techniques, lipo­suction and abdominoplasty, with minimal undermining, preserving the main vas­cularization to the superior abdominal ap and the secondary vascularization to the lower abdomen lateral areas and skin resection in the central area up to the muscle fascia, permitting safe plication and reducing the amount of tissue to be preserved in the lower abdomen, improving the aesthetic results, and turning the lipoabdomi­noplasty technique safer than the traditional abdominoplasty. He suggests, from the beginning, a simple and didactic classication, for patients who are candidates for this surgery, based on skin accidity, lipodystrophy, and diastasis of the rectus abdominis muscles and the extent of scars necessary for surgical correction, group­ing patients into four groups, with the respective indication of the type of surgery for each group: Group 1, liposuction; Group 2, mini-lipoabdominoplasty; Group 3, mid-lipoabdominoplasty; and Group 4, full lipoabdominoplasty. He also introduced the term mid-lipoabdominoplasty to the special cases where more skin resection is necessary than in mini-lipoabdominoplasty without umbilicus incisions and it’s impossible to pull down the superior abdominal ap (full lipoabdominoplasty), con­guring a simple and didactic classication for the lipoabdominoplasty technique based on lipodystrophy, the length of the scars, the amount of skin to be resected, and the diastasis of the rectus abdominis muscle.

Abstract Lipoabdominoplasty, the combination of lipoplasty with classical
abdominoplasty, since published by Avelar at the end of the 1990s, presented oppor­tunities for the treatment of body contour enhancing the aesthetics of anks and abdomen. According to the indications for the most appropriate technique in each case, we identied and classied the patients into nine different groups, which ranged from those presenting with mild fat with good-quality skin to massive weight loss patients with a high degree of accidity. The techniques described by the authors included lipoplasty and abdominoplasty alone, and four variations of lipoabdominoplasty.
The classication of lipoabdominoplasty indications offers a better understand­ing for treatment of the abdominal region. Lipoplasty, selective undermining, and maintenance of Scarpa’s fascia help reduce surgical trauma that is the main risk factor of hematoma and necrosis. This classications is easy to learn since the described procedures are already familiar to most plastic surgeons.

Introduction
Abdominal plastic surgery has evolved greatly from its original description (Callia,
1965) to the introduction of lipoplasty (Illouz, 1980; the combination of lipoplasty
and a small skin resection (Hakme, 1985); and the association od lipoplasty and full abdominoplasty (Matarasso, 1991). Since 2000, when it was proposed the overall treatment of the abdominal subcutaneous fat pad with deep lipoplasty, without under­mining and without fat pad resection (Avelar 2000), using video endoscopic diastasis suturing (Corrêa, 1995), we have used this technique to treat the abdominal region. Finally in 2001 Saldanha proposed associating lipoplasty and classical abdomino­plasty naming has technique lipoabdominoplasty. The varied indications were the basis for changes in surgical strategy and technique, depending on the need for treat­ment of the abdominal structures. The classication of lipoabdominoplasty indica­tions enabled us to standardize and systemize the associated lipoplasty and classical abdominoplasty techniques. It is based on ve sequential surgical phases or steps:
1. Dissection and sculpturing of the subcutaneous deep layer and supercial layer
through lipoplasty
2. Selective undermining and plication of the anterior rectus sheath
3. Preservation of the perforator vessels
4. Preservation of Scarpa’s fascia and deep fat
5. Skin resection and umbilical transposition
Based on this analysis, we propose a new clinical-therapeutic abdomen classi­cation to indicate the best technique for each case (Table9.1, Fig.9.1).

Preoperative Evaluation
Note that skin features, such as elasticity, laxity, wrinkles, surface irregularities, and presence of scars, must be taken. The umbilical scar must be positioned taking into consideration the navel’s position, its distance in relation to the pubis and xiphoid appendix, and scarring in the hypogastrium. The same parameters indicate the amount of skin to be removed. Through pinch test, the thickness, amount, and dis­posal of the fatty tissue are evaluated to estimate the volume of fat to be aspirated. Diagnosis of rectoabdominal diastasis for plication as well as its location, infra­umbilical or supraumbilical, to better determine the best technique to be used must be performed. Body contouring lipodystrophies in other areas are evaluated.

Surgical Technique
Saline solution and epinephrine at a concentration of 1:1,000,000 are inltrated. The abdomen is aspirated by the “scanner” technique, with the cannula holes turned laterally, using short circular movements into the supercial and deep layers rather than conventional undermining.
Infra-umbilical skin resection, plication of the rectoabdominal muscles, and mobilization of the umbilicus are performed, depending on the circumstances of each case. Scarpa’s fascia is always preserved, except during classical abdomino­plasty, to keep the supercial fatty layer at, preserving lymphatic drainage and suprapubic sensibility. Aspirative drainage is used postoperatively, with the closed suction drain placed into the selected undermining region, and is to be removed by the third to fth postoperative day in all cases in which lipoplasty is performed.
Lipoplasty
It is indicated exclusively for those patients who present with a light or mild fat pan­niculus and good-quality skin.
Lipoabdominoplasty I
This technique could be considered for patients who present with none to mild skin accidity in the infra-umbilical region, with or without inferior diastasis. After lipo­plasty of the abdomen and surrounding areas, an elliptical fuse of the skin located in the suprapubic area (Uebel, 1987), as well as the entire supercial fatty layer, is removed for the ap to be advanced over the preserved Scarpa’s fascia (Fig.9.2a). When inferior abdominal diastasis was present, Scarpa’s fascia was removed at the medial line to perform the rectoabdominal muscle plication in the inferior region and suture the supercial fascia borders (Fig.9.2b).
Lipoabdominoplasty II
This procedure is indicated for patients with mild skin accidity at the upper and lower abdomen in whom partial or total diastasis and high positioning of the umbili­cal scar are present. Following lipominiabdominoplasty as described above, the umbilicus is “oated” by cutting it free from the underlying fascial attachments. Selective upper undermining at the region of diastasis for the plication is performed, and the umbilicus is repositioned 2 to 5cm lower and xed to the aponeurosis of the
