Non-scarring Minimal Incision Neo-omphaloplasty in Abdominoplasty: The Alvarez Technique. A New Proposal.

BACKGROUND

Abdominoplasties are increasingly requested aesthetic, reconstructive surgical procedures that, in most cases, have shown the disadvantage of leaving an often-notorious periumbilical scar due to hypertrophy, keloid, or because it simply remains very visible over time, after surgery. The Alvarez technique (or nonscarring minimal-incision neo-omphaloplasty) is a completely new, unprecedented technique because it does not leave visible scars. This technique requires the generation of four small flaps and a purse-string suture system interacting with the aponeurosis of the rectus abdominis muscles, as well as the modification of the vertical abdominal plication, and management of the subcutaneous cellular tissue in the new umbilicus area, which, if executed correctly, provide adequate aesthetic results.

METHODS

A multicentric case-series scientific study is presented with a total of 94 patients who underwent classical abdominoplasties and neo-omphaloplasties with the aforementioned technique from August 2018 to December 2020. Pre-surgical and postoperative photographic files were collected.

RESULTS

Of the 94 patients, there were eight (8.5%) cases of seroma, which are not attributable to neo-omphaloplasty but inherent to the use of drains. There were five (5.3%) cases of umbilical dehiscence. In total, 89.2% (84 patients) showed a very high degree of long-term satisfaction, and 10.6% (10 patients) had a medium level of long-term satisfaction.

CONCLUSIONS

The Alvarez technique provides good aesthetic results that are well accepted among patients and surgeons, in the short and long term. It is useful for those patients who wish to undergo an abdominoplasty but cannot stand a scar in the umbilical region.
