Evaluation of the Neo-umbilicus Cutaneous Sensitivity Following Abdominoplasty

Abstract

Background

Abdominal cutaneous sensitivity loss after abdominoplasty is an undesirable outcome. However, little is known in the literature about sensitivity changes of the neo-umbilicus after abdominoplasty. The aim of this study was to evaluate post-abdominoplasty cutaneous sensitivity of the neo-umbilicus using clinical, quantitative, and reproducible methods.

Methods

Patients who underwent abdominoplasty were included, whereas the control group consisted of healthy volunteers with similar demographic characteristics but who did not undergo abdominoplasty. The umbilicus was divided into five zones, and superficial tactile sensitivity and spatial orientation were assessed subjectively (score 1–4) and objectively (Semmes–Weinstein monofilament examination).

Results

Twenty patients (45 ± 12 years) operated on consecutively between April 2012 and May 2016 and 14 healthy volunteers in the control group (39 ± 9 years) could be included. Although there were statistically significant differences (p = 0.0005) in the average cutaneous pressure thresholds between the control group (0.4 g/mm², range 0.07–2 g/mm²) and the study group (0.4 g/mm², range 0.07–4 g/mm²), patient satisfaction after a mean follow-up of 33 ± 16 months (range 10–62 months) was acceptable (mean satisfaction score 1.8 ± 0.7). Furthermore, spatial perceptions were precise in all patients and similar to the control group.

Conclusion

Our long-term results indicate that spontaneous reinnervation of the neo-umbilicus after abdominoplasty together with accurate spatial orientation can occur.
