The buttock is an extremely important area in woman’s sexuality and is considered a cornerstone Supragluteal fossettes: two hollows located on either side of the of female beauty. Although the concept of female beauty has medial sacral crest. They are formed by the posterior superior iliac changed over time, there are two constant items of femininity: spine and medially by the multifidus muscle. the breasts and the buttocks [2,3]. However, the parameters of V-shaped crease: two lines arising in the upper portion of the beautiful buttocks have varied according to time, culture, and gluteal crease toward the supragluteal fossettes. ethnicity [4,5]. Increasing number of patients are asking for esthetic improvement of their buttock profile or for correction of a Lumbar hyperlordosis is an additional feature that may deformity or irregularity. Buttock contouring is gaining more space contribute to beautiful buttocks. A beautiful gluteal contour should in the media and in doctors’ offices as well. Surgical techniques to also include the perigluteal areas namely the lower lumbar regions, improve buttocks contour have evolved dramatically over the last the trochanteric/hip area and the inner thighs. two decades [6]. Criteria of Beautiful Buttocks The gluteal region has been recognized as an important secondary sexual characteristic since the beginning of history and it has its place in the concept of beauty in all communities. The morphology of the gluteal region has been studied extensively in an objective way by many researchers, defining the changes in the gluteal region particularly with ageing and weight gain and loss [7-9]. Beautiful buttocks should be symmetric and rounded, with the greatest projection coming from the upper and middle thirds. In 2006, Cuenca-Guerra and Quezada published their results after carrying out an extensive anthropometric study [10]. They specified 4 main criteria for gluteal aesthetics (Figure 1,2): Lateral depression: a hollow on the lateral aspect of each buttock formed in its deepest point by the greater trochanter.

However, buttock size, lateral buttock fullness, and the buttock, regardless of ethnicity (Figure 3). It is the ratio between lateral thigh fullness are different among various ethnic types. the narrowest waist circumference to the hip circumference at the Roberts et al have summarized these ethnic differences as follows: level of maximum prominence of the buttocks [11]. The ration is (1) Caucasians, full but not extremely large buttock size, with two measured in posterior view and in lateral view (Figure 3) with types of lateral buttock fullness, either rounded or hollow, and with the most pleasing ratio 0.65 and 0.7 respectively (Table 1) [4]. no lateral thigh fullness; (2) Hispanics, very full buttock size, with very full lateral buttock and slightly full lateral thigh; (3) African Americans, buttock size as full as possible, with high fullness of lateral buttock and lateral thigh; and (4) Asians, small to moderate sized but shapely buttock, with no fullness of lateral buttock and lateral thigh [12]. These ethnic variations have to be kept in mind while evaluating the patient and planning how to manage his problem [5]. The surgical approach should restore the universal esthetic ideals and at the same time, it should respect and preserve the specific ethnic considerations for every patient. Gluteal Ptosis Gluteal ptosis was defined and classified in an elegant article published by Gonzalez [13]. The classification includes five degrees of severity and two factors: the length of the lower gluteal crease and the measurement of posterior gluteal tissue exceeding the crease at posterior mid-thigh line (Figure 4).
