RESUMEN
OBJECTIVE: To compare morbidity and aesthetic outcomes of full-thickness skin grafts (FTSGs) and split-thickness skin grafts (STSGs) in the reconstruction of the forearm free flap donor site. STUDY DESIGN: Case series, retrospective chart review. SETTING: Institutional microvascular database. SUBJECTS AND METHODS: Subjects who underwent forearm free flaps and FTSGs for donor site reconstruction from April 2016 to November 2017 were included. FTSGs were obtained from the donor forearm with a proximal S-shaped incision, thereby avoiding additional wound creation. Morbidity outcomes were compared to 68 consecutive patients with STSG reconstruction from January 2009 to May 2010. Complications, including tendon exposure, subjective functional impairment, complete graft loss, partial graft loss, infection, paresthesias, and hematoma/seroma, were evaluated, as were aesthetic outcomes. RESULTS: Sixty-eight patients underwent FTSG reconstruction. No significant differences between FTSGs and STSGs were demonstrated in terms of graft loss ≥40% (4% vs 4%, P = 1.000), partial graft loss (<40%) (29% vs 40%, P = .207), tendon exposure (9% vs 12%, P = .573), infection (15% vs 13%, P = .805), paresthesias (12% vs 7%, P = .382), subjective functional impairment (0% vs 2%, P = .316), or hematoma/seroma (2% vs 0%, P = .316). Aesthetic outcomes were better in the FTSG group compared to the STSG group, as determined by both patients (P = .004) and surgeon (P < .001). CONCLUSIONS: Our results advocate for the consideration of FTSGs in the reconstruction of the forearm free flap donor site given superior aesthetic results without additional donor site morbidity or additional wound creation when compared to STSGs.

OBJECTIVE: The anterolateral thigh (ALT) free flap is a soft tissue flap used in head and neck reconstruction. Occasionally, its perforators to the skin paddle are absent or too small to support the flap. Salvage options in this scenario have not been well described for head and neck reconstruction. METHODS: Multicenter review of 1,079 cases of planned ALT flaps where 28 initial flaps (2.6%) were discarded for nonviable skin paddle or lack of cutaneous perforators. Iatrogenic perforator injury was calculated separately. The total flap loss rate was 3.2%. RESULTS: In 12 cases, no perforators were noted after performing the anterior incision (early). Sixteen ALT flaps were discarded immediately before pedicle ligation (late). Reconstruction was salvaged by seven anteromedial thigh (AMT), six radial forearm, five contralateral ALT, four rectus abdominus myocutaneous, three vastus lateralis, three profunda artery perforator, two tensor fascia lata, one rectus femoris, two pectoralis major, one cervicofacial rotational, and one fibula flap. Of the 28 cases, 12 salvage cases did not involve an additional wound for the patient. Five of the seven AMT flaps were harvested after the ALT was identified as nonviable in the early time point. Two patients had no viable ALT flaps on bilateral lower extremities. CONCLUSION: The ALT flap is a reliable soft tissue flap, and rarely cutaneous perforators are not adequate to support the skin paddle. Multiple options exist to salvage the reconstruction without significant additional morbidity to the patient if said inadequacy is identified early.

OBJECTIVE: To demonstrate the safety and compatibility of microvascular couplers in patients undergoing postoperative magnetic resonance imaging (MRI) scans. STUDY DESIGN: Retrospective case series. METHODS: A consecutive review of 1,252 patients undergoing free tissue transfer for head and neck reconstruction at Oregon Health and Sciences University (OHSU) between 2010 and 2017 who had microvascular coupler Synovis, Baxter Deerfield, IL (Synovis Life Technologies, Saint Paul, MN) implantation were reviewed. One hundred fifteen patients had a subsequent MRI scan, which consisted of a variety of Phillips (Amsterdam, Netherlands) MRI machines ranging from 1.0 to 3.0 Tesla (T) in magnetic strength. RESULTS: These 115 patients underwent 121 free flaps with 131 couplers (including 32 flow couplers) utilized for venous anastomoses. Couplers ranged in size from 1.5 to 4.0 mm (3.0 mm [42%] followed by 3.5 mm [21%], 2.5 mm [19%], 2.0 mm [10%], 4.0 mm [6%], and 1.5 mm [2%]. Three hundred fifty-nine MRI scans (2 days to 91 months postoperatively) were obtained with 233 MRIs for cancer surveillance, and the remaining were obtained for neurologic disease, injury, or evaluation for metastases. No complications occurred related to the MRI and the metallic components of the coupler or other metal implants, such as reconstruction bars, vascular clips, or metallic surgical mesh. Additionally, no radiology report commented on MRI distortion due to the coupler placement, which contrasts the distortion seen with the other metallic implants. CONCLUSION: Microvascular couplers and their constitutive stainless-steel pins have not been found to cause any complications in a large series of consecutive patients undergoing multiple MRIs with magnetic strength up to 3 T. The U.S. Food and Drug Administration advocates medical alert notification for patients with couplers; however, hesitation regarding potential MRI scanning for surveillance or otherwise is unwarranted.

Given the high stakes for microvascular reconstruction, the majority of reconstructive surgeons have developed paradigms for pre, intra, and postoperative management that have proven to result in individual high success rates. Much has been done to identify and avoid perioperative factors that could potentially increase flap failure rates. Two example of this practice has been the generalized use of anticoagulation in free tissue transfer and the prohibition against vasopressor use in patients that are undergoing free tissue transfer. This manuscript will discuss these issues.

In facial plastic surgery, the potential for direct delivery of growth factors from platelet preparations has been of particular interest for use in facial rejuvenation, recovery after facial surgery, and wound healing. A literature search was conducted through PubMed for the terms PRP, PRFM, platelet-rich plasma, platelet-rich fibrin matrix, platelet preparations, platelet therapy, growth factors, platelet facial, platelet facial rejuvenation, platelet wound healing, platelet plastic surgery. Articles pertaining to the use of platelet preparations in facial surgery and wound healing in plastic surgery after 2001 were included. Thirteen in vitro studies showed use of platelet-rich plasma (PRP) and platelet-rich fibrin matrix (PRFM) had a significant effect on cellular activity. Twenty-four out of 28 animal studies exhibited favorable results with use of a platelet preparation, including five of six studies that showed enhanced fat graft survival with addition of a platelet preparation. Twenty-three case series and clinical trials were identified, only two of which showed no differences. Twenty-one reported favorable results with use of various platelet preparations. A total of 47 studies used PRP, four studies evaluated Leukocyte-rich PRP, and fourteen studies used PRFM. The vast majority of studies examined show a significant and measurable effect on cellular changes, wound healing, and facial esthetic outcomes with use of platelet preparations, both topical and injectable. One must also consider possible publication bias against null results that may have had an influence on the data that were available for review. However, the preponderance of studies suggests that platelet preparations might represent an as-of-yet untapped adjunct in facial plastic surgery.
