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.
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.
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.
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.
腹壁成形术是越来越常被要求实施的美容整形手术，在大多数情况下，该手术存在一个弊端，即术后因肥大、瘢痕疙瘩或仅仅随着时间推移仍非常明显，而留下通常很显眼的脐周瘢痕。阿尔瓦雷斯技术（或无瘢痕小切口新脐成形术）是一种全新的、前所未有的技术，因为它不会留下可见瘢痕。该技术需要生成四个小皮瓣和一个与腹直肌腱膜相互作用的荷包缝合系统，以及对垂直腹壁折叠进行改良，并处理新脐区域的皮下蜂窝组织，如果操作正确，可提供令人满意的美学效果。
呈现一项多中心病例系列科学研究，共有94例患者在2018年8月至2020年12月期间接受了采用上述技术的经典腹壁成形术和新脐成形术。收集了术前和术后的照片档案。
94例患者中，有8例（8.5%）出现血清肿，这并非新脐成形术所致，而是引流管使用所固有的问题。有5例（5.3%）出现脐部裂开。总体而言，89.2%（84例患者）显示出非常高的长期满意度，10.6%（10例患者）有中等程度的长期满意度。
阿尔瓦雷斯技术在短期和长期都能提供良好的美学效果，患者和外科医生都对其认可度很高。对于那些希望接受腹壁成形术但无法忍受脐部瘢痕的患者来说，该技术很有用。
