Summary
Post-bariatric abdominoplasty patients maintained skin sensation, including tactile and thermal sensitivity. This suggests that anchor-line abdominoplasty without flap undermining preserves sensory function in these individuals.
Area of Science:
- Plastic Surgery
- Bariatric Surgery Outcomes
- Sensory Physiology
Background:
- Bariatric surgeries are increasing globally, leading to a rise in post-bariatric plastic surgeries.
- Abdominoplasty in post-bariatric patients is associated with higher complication rates and potential skin hypesthesia.
- Evaluating sensory changes after abdominoplasty in this population is crucial.
Purpose of the Study:
- To assess skin sensation in post-bariatric patients undergoing anchor-line abdominoplasty.
- To compare sensory modalities including tactile pain, touch, thermal, and vibration sensitivity.
- To investigate the impact of abdominoplasty on skin sensation in formerly morbidly obese individuals.
Main Methods:
- Thirty-nine women who underwent open Roux-en-Y Gastric Bypass were evaluated.
- Sensory testing included tactile pain, touch, thermal, and vibration perception.
- A control group (n=15) and a study group (n=24) undergoing anchor-line abdominoplasty without flap undermining were assessed pre- and post-surgery.
Main Results:
- The control group exhibited high positivity across most sensory modalities.
- The study group demonstrated maintained sensation for most modalities post-abdominoplasty.
- Vibration sensitivity showed a non-statistically significant improvement in the study group.
Conclusions:
- Anchor-line abdominoplasty in post-bariatric patients appears to maintain skin sensation.
- The technique of non-undermining the xipho-pubic flap may contribute to preserving sensory function.
- Further research is warranted to confirm these findings and understand the underlying mechanisms.
