Where to find facial artery perforators: a reference point

Reconstructive surgery of the midface using facial artery perforator (FAP) flaps is being used more frequently now as it has been reported to provide better aesthetic results and reduce a traditional two-stage procedure to a one-stage technique. Wide acceptance of this approach is limited by poor understanding of the anatomy associated with this technique however. This was investigated through a cadaveric study. The facial artery (FA) of 16 cadaveric half faces were each identified, cannulated with coloured latex, and then dissected to give an accurate and quantified description of FA perforating branches. A lateral view picture of each specimen was taken and analysed using ImageJ 1.42q. Cadaveric dissections showed that each hemiface could be regarded as a single entity. Means: FA length = 116±22 mm, FA diameter = 2.62±0.74mm, number of FAPs = 4±2, FAP length = 14.12±3.46 mm, FAP diameter = 0.94±0.29 mm. A reference point, A, where FAPs were consistently found to originate was also identified. Therefore, the FAP flap is a viable and valuable addition to plastic reconstructive techniques. The localisation of point A with precise measurements can facilitate the design and use of such FAP flaps for the reconstruction of nasal, as well as perinasal and perioral defects

Total posterior leg open wound management with free anterolateral thigh flap: case and literature review.

Soft tissue coverage of the exposed Achilles tendon is a unique reconstructive challenge. In this report, we describe the management of a large posterior leg wound with exposed Achilles tendon using a free anterolateral thigh (ALT) flap. A careful review of alternative reconstructive options is included, along with their respective advantages and disadvantages. A 32-year-old white man suffered a fulminant right lower extremity soft tissue infection requiring extensive debridement of the entire posterior surface of the right leg. The resulting large soft tissue defect included exposure of the Achilles tendon. Reconstruction of the defect was achieved with an ALT flap and split-thickness skin graft for coverage of the Achilles tendon and gastrocnemius muscle, respectively. The patient was able to ambulate independently within 2 months of the procedure

ALGORITHM OF PARTIAL BREAST RECONSTRUCTION WITH PEDICLED PERFORATOR FLAPS

INTRODUCTION: The authors present an algorithm of partial breast reconstruction following quadrantectomy that allows to restore the breast volume defect with the use of pedicled perforator flaps. MATERIAL AND METHODS: Between March 2009 and May 2010, at the Plastic and Reconstructive Institute of University of Palermo, pedicled perforator flaps were used to integrate volume and/or breast skin in 12 patients after benign and malignant breast tumors. The flaps used were based on perforators of the thoraco-dorsal artery (TDAP) and of the intercostal arteries (ICAP). TDAP flaps were used to reconstruct defects in any breast quadrant, while ICAP perforator were used to reconstruct lateral and central inferior pole defects. RESULTS: All flaps survived completely. Breast size, shape and volume were satisfactorily restored. Contralateral breast procedure to adjust symmetry were not necessary. Donor sites scars were well hidden in the inframammary fold or under the brassiere. CONCLUSIONS : Partial breast reconstruction can be performed, in selected patients, with pedicled perforator flaps to restore both volume, shape and skin envelope. Donor site scars are negligible and better with the anterior ICAP because the scar is hidden in the submammary sulcus

Reconstrucción de defectos faríngeos

Reconstruction of pharyngeal defects continues to present a clinical challenge for the head and neck surgeon. We have different reconstructive options to preserve speech, airway, and swallowing functions. Reconstructive surgery implies a balance between oncologic cure, patient morbidity, and quality of life. Classical reconstructive techniques include pedicled cervical cutaneous or myocutaneous flaps and distal myocutaneous flaps such as from the pectoralis major. Current microvascular techniqu

Freestyle facial perforator flaps—a safe reconstructive option for moderate-sized facial defects

BACKGROUND: Perforators are a constant anatomical finding in the facial area and any known flap can in theory be based on the first perforator located at the flap rotation axis. METHODS: A case series of single stage reconstruction of moderate sized facial defects using 21 perforator based local flaps in 19 patients from 2008–2013. RESULTS: A sufficient perforator was located in every case and the flap rotated along its axis (76 %) or advanced (24 %). Reconstruction was successfully achieved with a high self reported patient satisfaction. Two minor complications occurred early on in the series and corrective procedures were performed in four patients. CONCLUSIONS: The random facial perforator flap seems to be a good and reliable option for the reconstruction of facial subunits, especially the periorbital, nasal and periocular area with a minimal morbidity and a pleasing result in a one stage outpatient setting. Level of Evidence: Level IV, therapeutic stud

Preoperative Imaging for Perforator Flaps in Reconstructive Surgery

Background: Although preoperative imaging of perforator vasculature in planning microvascular reconstruction is commonplace, there has not been any clear demonstration of the evidence for this practice, or data comparing the many available modalities in an evidence-based approach. This article aims to provide an objective, evidence-based review of the literature on this subject.\ud \ud Methods: The evidence supporting the use of various modalities of imaging was investigated by performing focused searches of the PubMed and Medline databases. The articles were ranked according to the criteria set out in March 2009 Oxford Centre for Evidence-Based Medicine definitions. Endpoints comprised objective outcome data supporting the use of imaging, including flap loss, unplanned returns to theater, operative time reduction, and surgeon-reported stress.\ud \ud Results: The objective high level of evidence for any form of preoperative perforator imaging is low with only small number of comparative studies or case series investigating computed tomographic angiography (CTA), magnetic resonance angiography, handheld Doppler, color duplex, and classic angiography. Of all modalities, there is a growing body of level 2b evidence supporting the use of CTA.\ud \ud Conclusion: While further multicenter trials testing hard outcomes are needed to conclusively validate preoperative imaging in reconstructive surgery, sufficient evidence exists to demonstrate that preoperative imaging can statistically improve outcomes, and that CTA is the current gold standard for perforator mapping

Factors Influencing the Incidence of Severe Complications in Head and Neck Free Flap Reconstructions.

Complications after head and neck free-flap reconstructions are detrimental and prolong hospital stay. In an effort to identify related variables in a tertiary regional head and neck unit, the microvascular reconstruction activity over the last 5 years was captured in a database along with patient-, provider-, and volume-outcome-related parameters. Retrospective cohort study (level of evidence 3), a modified Clavien-Dindo classification, was used to assess severe complications. A database of 217 patients was created with consecutively reconstructed patients from 2009 to 2014. In the univariate analysis of severe complications, we found significant associations (P < 0.05) between type of flap used, American Society of Anesthesiologists classification, T-stage, microscope use, surgeon, flap frequency, and surgeon volume. Within a binomial logistic regression model, less frequently versus frequently performed flap (odds ratio [OR] = 3.2; confidence interval [CI] = 2.9-3.5; P = 0.000), high-volume versus low-volume surgeon (OR = 0.52; CI = -0.22 to 0.82; P = 0.007), and ASA classification (OR = 2.9; CI = 2.4-3.4; P = 0.033) were retained as independent predictors of severe complications. In a Cox-regression model, surgeon (P = 0.011), site of reconstruction (P = 0.000), T-stage (P = 0.001), and presence of severe complications (P = 0.015) correlated with a prolonged hospitalization. In this study, we identified a correlation of patient-related factors with severe complications (ASA score) and prolonged hospital stay (T-stage, site). More importantly, we identified several provider- (surgeon) and volume-related (frequency with which a flap was performed and high-volume surgeon) factors as predictors of severe complications. Our data indicate that provider- and volume-related parameters play an important role in the outcome of microvascular free-flap procedures in the head and neck region

The Use of Keystone Flaps in Periarticular Wound Closure: A Case Series

The Keystone perforator island flap (Keystone flap), is a Type A fasciocutaneous advancement flap, consisting of two V to Y advancement flaps. Skin cancer excision around joints presents a number of reconstructive challenges. Owing to the mobile nature of joints, the optimal periarticular reconstructive option should possess the ability to provide adequate tissue coverage and withstand regional changes in tensile pressures. We report a single-surgeon series of five cases of periarticular keystone flap between 2014 and 2017. Data were collected from operation notes, clinical photography, histopathology, and outpatient clinic records. The indication for keystone flap was skin cancer in all cases (n = 5). The largest defect size post-excision in was 75 mm × 40 mm × 15 mm. All keystone flaps demonstrate a color and cosmetic appearance comparable to adjacent tissue. There were no major postoperative complications including flap failure or impaired range of joint movement in the follow up period. Superficial wound infection occurred postoperatively in one case. This is the first case series to discuss the use of keystone flaps in periarticular wound closure. Locoregional fasciocutaneous wound coverage offered by keystone flaps may alleviate the risks of graft failure, contour defects, and donor site morbidity associated with alternative reconstructive options, with good functional and cosmetic outcomes. We advocate their use as a robust reconstructive option in periarticular areas
