Current Fat Grafting Practices and Preferences: A Survey from Members of ISPRES.

Fat grafting has established its niche in a wide spectrum of aesthetic and reconstructive procedures. A consensus-based method of harvest, processing, enrichment, injection, and assessment is lacking, despite the rising trends in its application. We conducted a survey among plastic surgeons to evaluate and identify trends of fat grafting practices. Methods: We conducted an electronic survey with a 30-item questionnaire of 62 members of the International Society of Plastic Regenerative Surgeons. We collected demographic information, techniques, and experiences related to large volume (100-200 ml) and small-volume (<100 ml) fat grafting. Results: The majority of the respondents worked predominantly as aesthetic surgeons. The donor area selection was based on the patient's fat availability (59.7%). For fat enrichment, platelet-rich-plasma and adipose stem cells were routinely used by 12.9% and 9.7% of respondents, respectively. A 3- to 4-mm cannula with three holes was the most preferred instrument for large-volume fat harvesting (69.5%). For small-volume fat grafting, 2-mm cannulas (75.8%) with Mercedes tip (27.3%) were used most commonly. For processing, decantation of fat was performed by 56.5% of respondents (without exclusivity). For handheld injections (without exclusivity), respondents preferred a 1- to 2-mm cannula with a 1 cm3 syringe. The most popular method of outcome assessment was photographic evaluation. Conclusions: The respondents' tendencies were similar to those reported in the previous literature, with some exceptions, such as the technique for preparing fat and enrichment. A wider cross-sectional survey, involving national delegates and global representatives of plastic surgeons, is anticipated.

To Do or Not to Do? Neurorrhaphy in Great Toe Pulp Flap Fingertip Reconstruction.

Since its inception, the great toe pulp (GTP) flap has represented a valid therapeutic choice in the reconstruction of defects of the hand. This study illustrates the clinical outcomes of GTP free flaps performed without nerve anastomosis' mainly for fingertip defect reconstruction. Methods: We performed a retrospective, monocentric cohort study. All patients included in this study presented with fingertip traumatic injury, with tendon or bone exposure; reconstruction with GTP flap, without nerve reconstruction, was performed by the first author (L.T.) from May 2019 to October 2021. Results: All 37 flaps survived completely. Due to COVID restrictions' we had to send the tests and PROMs to our patients; 28 of them replied. Cold intolerance was reported by 12 patients (moderate in two cases and mild in ten cases). No pain was complained about either in hand or donor site (Visual Analog Score 0, at rest and at movement). Complete range of motion was achieved in 22 of 28 patients. All flaps recovered protective sensitivity. In every section of the Michigan Hand Outcome Questionnaire, all patients expressed a high level of satisfaction based on the reconstruction's function and aesthetics. Regarding the donor site morbidity, no patient complained about gait disturbance. Conclusions: This study showed that the GTP flap is the optimal choice for fingertip reconstruction, providing excellent functional and aesthetic results with durable and glabrous skin, satisfactory pulp contour, and sensory restoration. These results could be achieved with no need for nerve suture, especially in defects with no injuries proximal to the loss of substance.

Thinking Out of the Box: Use of the Radial Artery Distally to the Snuffbox as Recipient Vessel.

The use of the radial artery (RA) as a recipient vessel in the hand is mainly described in the snuffbox. However, we believe that employing the RA distally to the extensor pollicis longus (EPL) tendon may provide remarkable advantages. Methods: We conducted a prospective study from June 2019 until December 2021, which included all patients who underwent reconstructive procedures with the RA distally to the snuffbox as the recipient vessel. We reviewed patients' medical records: demographics, type of trauma, defect characteristics, microsurgical procedure, reoperations, and short- and long-term complications. Results: We found 23 patients eligible for this study; 22 patients required a reconstructive procedure due to a trauma and one for a congenital malformation. RA distal to snuffbox was always identified and judged reliable and apt as a recipient vessel. There were no issues with the anastomosis and no total flap failure in all cases. The morbidity in the recipient area was also minimal, with no mobility deficits, loss of sensation, or neuroma development. Conclusions: The RA is the primary vessel in the dorsum of the distal upper limb; performing the anastomosis distally to the EPL tendon may offer various advantages, making the surgery safer and less invasive.

Beauty and Function: The Use of Trimmed Great Toe in Thumb and Finger Reconstruction.

Finger amputations are one of the most common traumas of daily life. Regularization of the digital stump is the most widely used option in the literature today. The aim of this study was to evaluate a valid functional and aesthetic alternative to amputation. Methods: We retrospectively investigated our prospective database' selecting the patients who underwent trimmed great toe flap reconstruction for the amputation of a digit from September 2019 to November 2021. All the operations were performed by the first author (L.T.) in the Reconstructive Microsurgery Service of the University Department of Hand Surgery and Rehabilitation of MultiMedica Group. Results: No flap required anastomosis revision or had major complications. The length of the amputated finger was maintained, with a high functional and aesthetic result achieved. Conclusions: The trimmed great toe flap has proven to be a viable alternative to finger amputation in the reconstruction of thumb and long finger defects, leading to high aesthetic results. The morbidity of the donor site is reduced compared with the classic great toe flap, allowing a direct closure in most cases.

Tailored Skin Flaps for Hand Reconstruction.

Acquired soft-tissue defects of the hand can be a result of different types of trauma, infection, tumor resection, or burns. The evolution of the design and types of flaps have optimized the reconstruction and, nowadays, it is important to achieve not only a functional result but also an aesthetic result. The aim of the present study is to propose a model for treating a wide variety of skin defects in the hands based on our flap experience. Methods: We conducted a retrospective study from February 2019 to January 2022, which included all patients who underwent a skin flap for hand reconstruction. Patients' medical records were reviewed and data collected included demographics, smoking status, presence of risk factors, type of trauma, flap reconstruction, dimensions, reoperations, and long-term complications. Results: A total of 99 patients underwent skin flap-based reconstruction for hand trauma between February 2019 until January 2022. The mean age was 43.9 (range 38.3-49.5), 87.9% of patients were male, and follow-up was between 2 and 30 months; 90.9% of the flaps were free flaps, and the rest were pedicle flaps (3% of them being propeller flaps). Conclusions: When planning a hand reconstruction, it is vital to ensure that the outcomes are not only functional but also aesthetic, with minimum donor site morbidity; in this study, we showed a variety of flaps that can be applied to achieve this goal. We believe that the final decision should be made after comprehending the defect and the patient's preferences.

End-to-side Anastomosis on Digital Arteries: Just a Technical Choice or a Real Benefit?

High-quality evidence is currently poor regarding the benefits of end-to-end (ETE) or end-to-side (ETS) anastomosis in arterial and venous anastomoses, despite being postulated as a potential influence on outcomes. A sufficient microvascular anastomosis is indispensable for the success of any free tissue transfer. ETS microvascular anastomoses have been becoming increasingly important as they allow reconstruction even in patients with impaired vascular status. To the authors' knowledge, no studies have examined the choice of ETE or ETS anastomoses specifically for digital arteries. Methods: We conducted a retrospective study of ETE and ETS anastomosis cases; the only inclusion criteria was that digital arteries (proper, common) were the recipient vessels. Results: Fifty-seven cases met the inclusion criteria. All the venous anastomoses were ETE. Of these cases, four total intraoperative complications (immediate thrombosis) and only one case of complete failure were registered. The ETE group consisted of 49 patients and the ETS group of eight patients. A comparison of the mean ischemia time in the two groups showed no statistically significant difference (P = 0.121). Conclusions: We observed no difference in the reconstructive outcomes of hand free-flaps and reconstruction between ETE or ETS digital arteries anastomoses. The successful microsurgical reconstruction was independent of anastomotic technique. In particular, the results of our study demonstrated no statistically significant increase of the ischemia time; thus, no prolongation of operative time can be attributed to the higher technical challenge of the anastomosis.

Minimally invasive harvest of the latissimus dorsi flap for breast reconstruction: A systematic review.

BACKGROUND: Poor cosmetic results with oncoplastic and implant-based breast reconstruction have stimulated an interest in latissimus dorsi flap (LDF)-based reconstruction. We reviewed the surgical techniques and outcomes of the LDF harvested with minimally invasive surgery. METHODS: A systematic search was conducted across PubMed-MEDLINE, Web of Science, Scopus, and Ovid-MEDLINE(R). Data on surgical outcomes were extracted. RESULTS: 31 articles were included reporting on 857 reconstructive procedures using a LDF harvested, 497 were endoscopic-assisted LDF (EALDF) (58%) and 174 were robotic-assisted LDF (RALDF) (20.3%). The average flap harvest time was 84.04-min for EALDF and 106.14-min for RALDF. With an EALDF, the incidence of haematoma, seroma, and wound dehiscence ranged between 0%-16.6%, 0%-48%, and 0%-6.2%, respectively. Using RALDF, the incidence of seroma was between 0%-26.1% and 0%-3.4% for haematoma. CONCLUSIONS: While the indications for a LDF harvested with MIS are limited, its main advantage for breast reconstruction is the absence of the back scar.

Partial Ear Reconstruction with a Prelaminated Induced Expanded Radial Artery Flap.

A 76-year-old man underwent an extensive resection for squamous cell carcinoma 2 years before, resulting in the loss of the superior half of the right ear, without any attempt at reconstruction. The decision was to reconstruct with a combined suprafascial tissue expansion, an alloplastic framework fabricated with porous polyethylene, and a radial artery free flap. At 1-year follow-up, the patient was satisfied with the result. We believe this represents a novel approach to be considered for partial ear reconstruction.
