Abstract
Vascularization is vital in bone tissue engineering, supporting development, remodeling, and regeneration. Lack of vascularity leads to cell death, necessitating vascularization strategies. Angiogenesis, forming new blood vessels, provides crucial nutrients and oxygen. Pre-vascularized gelatin-coated β-tricalcium phosphate (G/β-TCP) scaffolds show promise in bone regeneration and vascularization. Our study evaluates G/β-TCP scaffolds' osteogenic and angiogenic potential in vitro and a canine model with vascular anastomosis. Channel-shaped G/β-TCP scaffolds were fabricated using foam casting and sintering of a calcium phosphate/silica slurry-coated polyurethane foam, then coated with cross-linked gelatin. Buccal fat pad-derived stem cells (BFPdSCs) were seeded onto scaffolds and assessed over time for adhesion, proliferation, and osteogenic capacity using scanning electron microscopy (SEM), 4,6-diamidino-2-phenylindole (DAPI) staining, Alamar blue, and alkaline phosphatase (ALP) assays. Scaffolds were implanted in a canine model to evaluate osteogenesis and angiogenesis by histology and CT scans at 12 wk. Our studies showed preliminary results for G/β-TCP scaffolds supporting angiogenesis and bone regeneration. In vitro analyses demonstrated excellent proliferation/viability, with BFPdSCs adhering and increasing on the scaffolds. ALP activity and protein levels increased, indicating osteogenic differentiation. Examination of tissue samples revealed granulation tissue with a well-developed vascular network, indicating successful angiogenesis and osteogenesis was further confirmed by a CT scan. In vivo, histology revealed scaffold resorption. However, scaffold placement beneath muscle tissue-restricted bone regeneration. Further optimization is needed for bone regeneration applications.

Abstract
PURPOSE OF REVIEW Massive palatal defects resulting from palatoplasty failures arising from cleft palate repair complications present ongoing challenges in clinical practice. The purpose of this review is to provide up-to-date insights into aetiology, risk factors, surgical techniques, and adjunctive therapies, aiming to enhance the understanding of such complex cases, and optimize patient outcomes. RECENT FINDINGS Primary palatoplasty has fistula recurrence rates ranging from 2.4% to 55%. Factors such as cleft width, surgical repair method, and patient characteristics, influence the likelihood of failure. Classifications such as the Pakistan Comprehensive Classification and Richardson's criteria aid in assessing defects. Surgical options range from local flaps and revision palatoplasty to regional flaps (e.g., buccinator myomucosal, facial artery-based flaps, tongue flaps, nasal septal flaps) to free microvascular flaps. Alternative approaches include obturator prostheses, and acellular dermal matrix has been used as an adjuvant to multiple repair techniques. Hyperbaric oxygen therapy has emerged as an adjunctive therapy to enhance tissue healing. SUMMARY This comprehensive review underscores the intricate challenges associated with massive palatal defects resulting from palatoplasty failures. The diverse range of surgical and nonsurgical options emphasizes the importance of patient-centric, individualized approaches. Practitioners, armed with evidence-based insights, can navigate these complexities, offering tailored interventions for improved patient outcomes.

Abstract
BACKGROUND In the surgical treatment of head and neck locally advanced malignancies, microvascular free flaps represent the most valuable solution to reconstruct the tissue defect after resection of the primary neoplasm. In particular, microvascular free flaps allow to restore the functional and aesthetical features of the head and neck compartments. The superficial circumflex iliac perforator (SCIP) flap represents, as an evolution of the groin flap, a valid alternative to the radial fasciocutaneous free (RFFF) flap or the anterolateral thigh (ALT) flap. METHODS This systematic review adhered to the recommendations of the Preferred Reporting Items of Systematic Reviews and Meta-analysis (PRISMA) 2009 guidelines. A computerized MEDLINE search was performed using the PubMed service of the U.S. National Library of Medicine ( www.pubmed.org ) and Scopus database ( www.scopus.com ). Two authors screened the articles, then selected and extracted data on malignancies characteristics, reconstructive techniques, outcomes, and complications. RESULTS A total of 25 articles were selected and reviewed among the 39 identified through the search string. Six out of the selected 25 articles were case reports, while the remaining 19 articles were retrospective case series. The whole study population was represented by 174 oncologic patients undergoing ablation of a head and neck tumor and reconstruction with a SCIP flap. The site of reconstruction was the oral cavity in 125 (71.0%) patients, being the tongue the most common subsite in 73 (41.5%) patients, the pharynx in 10 (5.7%) cases, the larynx in 3 (1.7%) and head and neck skin in 36 (20.4%) patients. Only two cases of total flap loss were reported. Partial flap loss or shrinkage requiring minor surgical revisions was observed in 11 patients (6.32%). Primary closure of the donor site was achieved in the whole study population, according to the available data. CONCLUSIONS In head and neck postoncological reconstruction, despite the caliber and the length of the pedicle, SCIP flap offers a pliable and thin skin paddle, allowing single-stage resurfacing, medium to large skin paddle, possibility of composite-fashion harvest and a well-concealed donor site.

Free flap transfer with supermicrosurgical technique for soft tissue reconstruction: A systematic review and meta-analysis. Microsurgery 2023; 43:171-184. [PMID: 35551691 DOI: 10.1002/micr.30894] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2021] [Revised: 03/16/2022] [Accepted: 04/29/2022] [Indexed: 11/12/2022]
Abstract
BACKGROUND Supermicrosurgery is a technique that allows microsurgeons to accomplish dissections and anastomoses of vessels and nerve fascicles with diameters of ≤0.8 mm. Considering the potential benefits of this technique and limited literature synthesizing the outcomes of supermicrosurgery, the aim of this study was to summarize the available evidence of reconstructive supermicrosurgery and to estimate the success rate. METHODS We conducted a comprehensive search across PubMed, Scopus, Embase, and Web of Science. We included patient-based studies reporting on procedures for soft-tissue reconstruction with free flaps specifying the use of supermicrosurgery. We excluded studies reporting on lymphatic surgery, solely peripheral nerve surgery, and tissue replantation. Our primary endpoint was to calculate the flap success rate. Pooled estimates were calculated using a random-effects meta-analytic model. RESULTS Forty-seven studies reporting outcomes of 698 flaps were included for qualitative synthesis. Overall, 15.75% of flaps were used for head and neck, 4.4% for breast and trunk, 9.3% for upper limb, and 69.2% for lower limb reconstruction. The most used flap was the superficial circumflex iliac artery perforator flap (41.5%). The overall flap success rate was 96.6% (95%CI 95.2%-98.1%). The cumulative rate of partial flap loss was 3.84% (95%CI 1.8%-5.9%). The overall vascular complication rate resulting in complete or partial flap loss was 5.93% (95%CI 3.5%-8.3%). CONCLUSIONS Supermicrosurgery displays a high success rate. Further studies are necessary to explore the true potential of supermicrosurgery. This technique reformulates the boundaries of reconstructive surgery due to its extensive application.

Abstract
Most of the articles on the groin flap were published in the period from 1975 to 2010, from 2015 to 2022, the SCIP flap surpassed the groin flap in the number of publications. According to the results of a literature search in PubMed and RINC, 30 articles were found and selected, including 288 flaps from the iliac region. The length of the vascular pedicle, the diameter of the vessels, the complications, the prevalence of the flap in the reconstruction of the head and neck, the thickness and the size of the flap were evaluated. Both of these flaps have the same nutrition, but different levels of dissection. In comparison with the groin flap, the SCIP flap has a longer vascular pedicle, which can be enlarged due to new techniques, which also allows it to be used as an ultra-thin flap, and it reduces the need for secondary procedures for defatting and reduces the risks of the complications in the donor area. The thickness of the SCIP flap is less than the groin one, which, according to the author, increases the aesthetic level of operations in the facial area in the case of the texture and color of the flap. Vascular anatomy of the SCIP flap is variable, therefore, the use of preoperative planning is necessary. Despite this, complications in the donor or recipient area during reconstruction with a SCIP flap are minimal. It has been proved that the SCIP flap is versatile and safe in all aspects of reconstruction. It can be concluded that the SCIP flap should be considered as a «workhorse» in reconstructive microsurgery of soft tissues of the throat and oral cavity.

Abstract
The facial and submental regions are supplied by complicated neurovascular networks; therefore, facial aesthetic injections may be associated with serious adverse events such as skin necrosis and blindness. Pre-injection localization of neurovascular structures using high-resolution ultrasound can theoretically prevent unexpected complications. Therefore, a systematic protocol that focuses on these facial neurovascular structures is warranted. In this pictorial essay, we discuss the sonoanatomy of facial and submental neurovascular structures and its relevance to aesthetic injections. Moreover, we have highlighted the mechanisms underlying potential neurovascular injuries during aesthetic injections.

Abstract
The facial artery (FA) is the main artery supplying the anterior face, making this artery a very important structure to consider while performing plastic and reconstructive procedures. The literature shows discrepancies in anatomical classifications and the frequency of occurrence of individual variations. Therefore, the goal of this meta-analysis is to provide surgeons with helpful knowledge about the variety of the termination of FA. Articles with data about the termination of the FA were found in major online medical databases such as PubMed, Scopus, Embase, Web Of Science, and Cochrane Library. A total of 1346 articles were initially evaluated by two independent reviewers. Out of those, 24 articles matched the required criteria, and were used in this meta-analysis. A total of 2119 studied FAs were included in this study. The FA termination patterns were divided into five previously classified types. The data show that the FA terminates most frequently as the lateral nasal or angular artery with the prevalence for this group being 69.81% (95% confidence interval [CI]: 59.83%-78.94%). Authors believe that this is the most accurate and up to date study regarding termination patterns and the prevalence of the FA. The results of this meta-analysis could provide a helpful tool for surgeons preforming plastic and cosmetic procedures, especially when injecting dermal fillers or choosing and preforming facial flaps. Detailed anatomical knowledge about the FA may prevent potential surgical complications.

Abstract
The surgical repair of full-thickness defects involving the alae nasi is complex. Pedicle flaps such as frontal and nasolabial flaps can be used, but require several interventions with different techniques. In contrast, free flaps from the foot of the ear helix allow the three layers of the nasal wings to be reconstructed in a single operation. Nevertheless, in the classical approach, the vascular pedicle is short. Although some authors have proposed raising the flap in a retrograde manner, this still yields a relatively short pedicle with narrow vessels. In the companion paper, we demonstrated that a posterior auricular artery helix root free flap (PAAHF) can be harvested from the posterior auricular vessels, thus increasing the useful pedicle length. The case of a patient with basal cell carcinoma of the left ala is presented here. A right helix root free flap was anastomosed with the facial vessels at the left mandibular notch. This new flap overcomes the main limitation of the classical helix root flap, namely the length of the pedicle. It has all of the morphological qualities of the classical flap, but with simpler vascular assembly, since autologous venous grafts and complex anastomoses are not required.

Abstract
OBJECTIVES Mid and upper face free flaps frequently are associated with challenges due to pedicle length. We sought to evaluate the frequency at which alternative pedicle maneuvers were required for these reconstructions and determine if there was any association with flap survival or postoperative complications. STUDY DESIGN Retrospective review at three tertiary care institutions. METHODS Database review. RESULTS Free flap reconstruction of the upper and midface was performed in 295 patients (108 bony, 187 soft tissue). In 82% of cases, the vessels reached the ipsilateral neck for anastomosis to traditional target vessels. Arterial grafts were required in 2% of reconstructions (4% bony and 1% soft tissue). Venous grafting was required in 7% of reconstructions (21% fibula, 16% scapula, and 3% soft tissue) and was associated with an increase in flap failure rate (19% vs 3%, P = .003). The most common recipient artery for revascularization was the cervical facial artery (78%). Alternate recipient vessels were selected in 13% of cases, including the superficial temporal vessels (7%), distal facial branches through a separate facial incision (4%), and angular vessels (2%). Vein grafting was associated with a higher flap failure rate. Alternative maneuvers did not affect need for intraoperative pedicle revision or complications. CONCLUSIONS In upper and midface reconstruction, vascular grafting, targeting more distal branches of the facial system, or additional maneuvers to optimize pedicle orientation is often required to secure revascularization. Vein grafting is associated with a higher free flap failure rate. Scapular border flaps often require vascular grafting or atypical anastomotic locations.
