“…Correria et al have reported that the depth of umbilicus increased significantly with age, especially after 18 years of age, and the ratio of the xiphoid-umbilicus distance to the xiphoid-pubis distance was 2.2 times higher in adults compared with that in children. They also observed the umbilicus height and width ratios decreased with age due to growth of the abdomen [7].…”

The umbilicus is essential to the aesthetic appearance of the abdomen. However, very little has been written about the exact location of the aesthetically pleasing umbilicus as far as the Turkish population is concerned. Although a variety of reconstructive methods are available, no real standards define the location and shape of the umbilicus. This is a single cross-sectional cohort study focused on the morphometric analysis of the umbilicus in 300 adults between 18 and 65 years old. All data, including standardized measures and pictures, were determined. A total of 150 women and 150 men are incorporated into the study who referred to Kahramanmaraş Sütçü İmam University Hospital between January and July 2018. In this study, the authors observed that the umbilicus is situated around the midline plane such that the ratio of the distance between the xiphisternum and the umbilicus and the distance between the pubic symphysis and the umbilicus is 1.45. Also, the ratio of the distance between the umbilicus and anterior superior iliac spine and the between anterior superior iliac spine is approximately 0.6/1. Most umbilicus was found to be oval shape in males while round shape in females. Umbilical hood orientation was with an inferior hood in males while superior-inferior hood in females in my study at Turkish population. The present study was performed to determine the normal anatomical position of the umbilicus and umbilicus shapes in a sample of Turkish people and to obtain ideal ranges for repositioning neo-umbilicus during abdominoplasty.

“…It is located just below the midpoint of the linea alba and anchored into position by the aforementioned deeper structures. 5,14 Variability exists within the population concerning the positioning of the umbilicus, with a lower position noted in people of advanced age, men, and obese individuals. Tensile strength of the linea alba surrounding the umbilicus is thinner in women, people older than 50, obese individuals, and multiparous women 15 ; the tensile strength of this structure is in proportion to its thickness.…”

Background: The umbilicus is often not a midline structure. Centralization of the umbilicus during an abdominoplasty is routinely performed at the level of the skin; however, this is associated with a high rate of postoperative reversion. The authors propose using an eccentric fascial plication centered on the true midline to maintain postoperative centralization of the umbilicus in addition to correction at the skin level. Methods: A retrospective study was conducted of all patients between 2015 and 2019 who underwent abdominoplasty with either skin only (concentric plication) or fascial (eccentric plication) umbilical centralization. The Fisher exact test and t test were used to compare the two groups and assess differences in rates of umbilical reversion. Results: A total of 71 patients were included in the study; the majority of patients were women [n = 69 (97%)] and White [n = 50 (70%)]. There were 28 (39%) patients who underwent concentric plication, and 43 (61%) had eccentric plication. Mean body mass index in the concentric and eccentric groups was 32 kg/m2 and 28.5 kg/m2, respectively. Average follow-up was 51.6 months for concentric plication and 27.8 months for eccentric plication. Of those who received concentric plication, 10 patients (36%) had their umbilicus revert to the preoperative position; none in the eccentric plication group reverted (P < 0.0001). Conclusions: Midline placement of the umbilicus during an abdominoplasty is important in providing symmetry to optimize aesthetics. Eccentric fascial plication maintains the centralization of the umbilicus when compared with concentric fascial plication with skin-only centralization. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

“…many recent reports, the XU:XP (length from the xiphoid process to the pubic symphysis) was used to measure the position of the umbilicus. [6][7][8][9][10][11] However, the XU:XP ratio is markedly high in the neonatal period and changes throughout childhood. [8][9][10][11] In our study, the XU:XP gradually changed from infancy through childhood, and the change was drastic in infancy (Figure 2).…”

Background Although there have been many reports concerning the normal position of the umbilicus, the measurements were performed from the surface of the body in all cases. We examined computed tomography (CT) images to determine the accurate position of the umbilicus in children. Methods We retrospectively examined the CT data of 120 Japanese children (60 boys, 60 girls). The angle between both iliac crests to the umbilicus (IU angle), the angle between both anterior superior iliac spines and the umbilicus (AU angle), and the ratio of the length from the xiphoid process to the umbilicus and length from the umbilicus to the pubic symphysis were measured. Results The mean AU angle was 33.7° ± 5.1°, showing the least data variations. A significant difference was noted in the AU angle between boys and girls (32.7° ± 4.6° and 34.6° ± 5.4° respectively; p = 0.04). When we defined the position of the umbilicus as an AU angle of 33° in boys and 35° in girls, 115 children (95.8%) fell within ±10°. Conclusions The AU angle is the preferable predictor of the umbilicus position in children.
