Abdominoplasty is a widely utilized cosmetic surgery procedure. Despite its popularity, seroma formation remains a prevalent complication. Seroma can lead to extended recovery time, increased medical appointments, and the potential for infection or the need for additional surgical revision. Preserving Scarpa's fascia may mitigate the risk of seroma in patients following abdominoplasty. The goal of this systematic review was to determine the impact of preserving Scarpa's fascia on the occurrence of seroma and total drain output following an abdominoplasty procedure. This review searched academic literature in MEDLINE (via PubMed), EMBASE (OvidSP), and the Cochrane Central Register of Controlled Trials (CENTRAL) for clinical and observational studies published in peer-reviewed journals, from March 2022 to November 2022, that evaluated the impact of preserving Scarpa's fascia on postoperative seroma and total drain output during abdominoplasty. The primary outcomes of interest were seroma and total drain output, with secondary outcomes of interest including hematoma, time to drain removal, length of hospital stay, wound dehiscence, and infection rate. The systematic review of 8 studies, involving 846 patients, found that the preservation of Scarpa's fascia during an abdominoplasty procedure was associated with decreased seroma occurrence, reduced drain output, faster drain removal, and fewer infections. However, it did not affect the incidence of hematoma, hospital stay duration, or wound dehiscence. The preservation of Scarpa's fascia during an abdominoplasty procedure should be considered as a routine practice, because it has been shown to result in reduced seroma incidence rates and faster drain removal., (© The Author(s) 2023.

Background: Mouth corners are an essential part of the centrofacial area for perception of attractiveness and emotions. Downturned mouth corners are a result of aging or have a congenital origin. Different mouth corner lifting techniques are described in the literature., Objectives: This review was performed to systematically assess and compare invasive and noninvasive mouth corner lifting techniques and their effectiveness, patient satisfaction, and adverse effects., Methods: MEDLINE (via PubMed), EMBASE (OvidSP), and the Cochrane Central Register of controlled trials databases were searched for clinical and observational studies published in peer-reviewed academic journals with abstracts available (searched from May 18, 2019, to December 18, 2021). Outcomes of interest were aesthetic mouth corner lifting techniques, the degree of lift as well as the longevity of the lifting effect, patient satisfaction, and adverse effects. Techniques were subdivided in invasive techniques and noninvasive techniques., Results: Out of 968 studies found from the search, 11 were included in the qualitative analysis. In general, surgical techniques seem to have a better mouth corner lifting effect than nonsurgical techniques; however, objective evidence is weak, and surgery inevitably results in a scar. Reported patient satisfaction was good for both surgical and nonsurgical techniques and no severe complications have been described., Conclusions: Surgical techniques seem to have a better lifting effect on mouth corners than nonsurgical techniques. Nevertheless, objective evidence is weak, and a scar is inevitable., (© 2022 The Aesthetic Society.)
