Centralizing the Umbilicus in Abdominoplasty: Eccentric versus Concentric Fascial Plication in Addition to Medializing at the Skin.

Abstract

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. 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. 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/m 2 and 28.5 kg/m 2 , 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). 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. Therapeutic, III.
