Resolution of ptosis is a key step to the success of many plastic surgery procedures. Ptosis is a manifestation of tissue stretch. Tissue stretch can occur as a result of the natural aging process or health of the patient, or tissue may stretch under added weight or volume, such as when implants are placed. Surgical rejuvenation of ptotic tissues is very effective and results in marked changes in the patient profile yet the tissue that resulted in the need for the procedure first place has not improved and ptosis can recur. Recent developments in long-term resorbable porous materials have provided surgeons with the opportunity to experiment with tissue reinforcement in plastic surgery procedures. These new materials have a low profile, rapid tissue integration, and a long-term strength retention profile. Long-term resorbable scaffolds such as poly-4-hydroxybutyrate (P4HB) natural scaffold (GalaFLEX scaffold, Galatea Surgical, Inc., Lexington, MA) have shown promise for a host of plastic surgery indications. This article presents clinical experience with GalaFLEX for soft tissue reinforcement in three different clinical applications; including the reinforcement of the superficial muscular aponeurotic system (SMAS) in minimally invasive facelift, reinforcement of the skin envelope in mastopexy, and reinforcement of the breast capsule (pocket) in revisional breast surgery. Soft tissue reinforcement has been shown to provide increased mechanical strength as well as improved maintenance of postoperative results.

上睑下垂的矫正对于许多整形手术的成功至关重要。上睑下垂是组织拉伸的一种表现。组织拉伸可能是自然衰老过程或患者健康状况导致的结果，或者组织可能在额外的重量或体积下拉伸，例如植入假体时。对上睑下垂组织进行手术修复非常有效，会使患者的外形发生显著变化，但最初导致需要进行该手术的组织并未得到改善，上睑下垂可能会复发。长期可吸收多孔材料的最新进展为外科医生提供了在整形手术中试验组织强化的机会。这些新材料外形小巧、组织整合迅速且具有长期的强度保持特性。诸如聚-4-羟基丁酸酯（P4HB）天然支架（GalaFLEX支架，Galatea Surgical公司，马萨诸塞州列克星敦）等长期可吸收支架已在众多整形手术适应症中展现出前景。本文介绍了GalaFLEX在三种不同临床应用中用于软组织强化的临床经验；包括在微创面部提升术中强化表浅肌肉腱膜系统（SMAS）、在乳房上提术中强化皮肤包膜以及在修复性乳房手术中强化乳房包膜（腔隙）。软组织强化已被证明可提供增强的机械强度以及改善术后效果的维持。
