Soft tissue augmentation procedures are becoming more popular these days. Different soft tissue graft harvesting approaches have been proposed. Nonetheless, the location of the donor site (whether anterior-, lateral-, superficial-, deep-palate or the maxillary tuberosity) can affect the graft shape and its composition. Soft tissue grafts from the maxillary tuberosity are rich in connective tissue fibers, with minimal presence of fatty or glandular components. Clinical, histological, and molecular evidence shows that a soft tissue graft obtained from the maxillary tuberosity has unique properties. In addition, harvesting from this area presents minimal risk for intra- or postoperative complications, leading to reduced patient morbidity. The aim of this commentary is to discuss the advantages and disadvantages of harvesting a soft tissue graft from the tuberosity and to compare it with the traditional palatal graft, while highlighting functional, esthetic, and patient-related outcomes.
如今，软组织增加手术越来越受欢迎。人们提出了不同的软组织移植物采集方法。然而，供体部位的位置（前、侧、浅层、深层腭或上颌结节）会影响移植物的形状和组成。上颌结节的软组织移植物富含结缔组织纤维，脂肪和腺体成分很少。临床、组织学和分子证据表明，从上颌结节获得的软组织移植物具有独特的特性。此外，从该区域采集移植物的风险很小，术后并发症也很少，从而降低了患者的发病率。本文的目的是讨论从结节采集软组织移植物的优缺点，并将其与传统的腭移植物进行比较，同时强调功能、美观和患者相关的结果。
