Non-surgical Jowl and Jawline Rejuvenation with Resorbable Suspension Threads and Superficial Enhanced Fluid Fat Injection (SEFFI)

Background: Collagen and elastin play a crucial role in skin traction; their deterioration contributes to causing skin sagging and laxity with time. Soft tissue ptosis modifies the mandibular profile in addition to enhancing the nasolabial folds, lines of puppets and lateral eyebrow area; moreover, skin atrophy and volume loss are major factors involved in facial aging, contributing to the formation of facial rhytids, skeletonization, and pseudo-descent of the midface. Non-surgical face and neck rejuvenation lift with resorbable suspension threads and Superficial Enhanced Fluid Fat Injection (SEFFI) can be used as a temporary procedure until the aging appearance requires a more radical approach.Methods: Retrospective analysis from January 2019 to February 2022 of a 232 cases series of patients seeking a rejuvenation of the lower frame of the face (jowls and jawline) included in the study. The cases were performed in the base-office medical suites of some of the Authors. All of them were treated with resorbable threads in the face subcutis without modifying the superficial musculoaponeurotic system and platysma.Result: Data collection on base-office medical suites treatment time, size and length selection, and post- treatment complications were included. The most frequent complication was bruise in the harvesting area (healed within 3-7 days) and in the jowl and jawline; cases of skin irregularities in threads (all cases solved 7-10 days); no skin irregularities or lumpiness in tissue graft.Conclusion: Non-surgical face and neck treatment with resorbable suspension threads and Superficial Enhanced Fluid Fat Injection (SEFFI) getting a valid method as a temporary procedure until the aging appearance requires a more radical approach.
