Dynamic anatomical study of the posterior brachial artery perforator flap: Aesthetic refinement and clinical results

BackgroundReconstruction of the axillary fossa represents a surgical challenge given the functional implications for mobility of the upper limb. The posterior brachial flap is a solution of choice for this indication, providing fine and functional local reconstruction, but little is known about its perforasome. This study aimed to identify the location of the perforator, analyze perfusion flow, and link vessel distribution, and propose an aesthetic refinement to the surgical technique by medializing the skin paddle to conceal aesthetic scarring at the donor site. MethodsFifteen fresh cadavers were harvested and dissected. Twenty-six arms were injected with methylene blue. Two arms were injected with radiopaque dye. A dynamic (4-dimensional) computed tomographic angiography was performed to complete the analysis. ResultsThe perforasome was centered on the posterior axis of the arm with a perfusion area ranging from 82.2 to 142.9 cm², with a median of 112.7 (96.7–125.6) cm². The median length of the pedicle was 83 mm on an average (65–91 mm). Its caliber at the emergence of the source vessel had a mean diameter of 1.43 mm (1.27–1.61 mm). The distal limit of the paddle was located on an average 10.7 cm from the olecranon (7.8–12.2 cm). The scans showed direct linking vessels toward the perforasomes on the medial side of the arm, suggesting that it is possible to medialize the cutaneous paddle. ConclusionThe posterior brachial flap presents with a constant perforasome. It can be harvested more medially than previously described to improve the aesthetic results, while maintaining reproducibility and satisfactory vascular reliability.

Reconstruction for Salvage Laryngectomy With Limited Pharyngectomy

Closure technique for optimization of postoperative and functional outcomes following salvage laryngectomy remains an area of debate among head and neck surgeons. To investigate the association of salvage laryngectomy closure technique with early postoperative and functional outcomes. This retrospective cohort study included patients from 17 academic, tertiary care centers who underwent total laryngectomy with no or limited pharyngectomy after completing a course of definitive radiotherapy or chemoradiotherapy with curative intent between January 2011 and December 2016. Patients with defects not amenable to primary closure were excluded. Data were analyzed from February 14, 2021, to January 29, 2024. Total laryngectomy with and without limited pharyngectomy, reconstructed by primary mucosal closure (PC), regional closure (RC), or free tissue transfer (FTT). Patients were stratified on the basis of the pharyngeal closure technique. Perioperative and long-term functional outcomes were evaluated with bivariate analyses. A multivariable regression model adjusted for historical risk factors for pharyngocutaneous fistula (PCF) was used to assess risk associated with closure technique. Relative risks (RRs) with 95% CIs were determined. The study included 309 patients (256 [82.8%] male; mean age, 64.7 [range, 58.0-72.0] years). Defects were reconstructed as follows: FTT (161 patients [52.1%]), RC (64 [20.7%]), and PC (84 [27.2%]). A PCF was noted in 36 of 161 patients in the FTT group (22.4%), 25 of 64 in the RC group (39.1%), and 29 of 84 in the PC group (34.5%). On multivariable analysis, patients undergoing PC or RC had a higher risk of PCF compared with those undergoing FTT (PC: RR, 2.2 [95% CI, 1.1-4.4]; RC: RR, 2.5 [95% CI, 1.3-4.8]). Undergoing FTT was associated with a clinically meaningful reduction in risk of PCF (RR, 0.6; 95% CI, 0.4-0.9; number needed to treat, 7). Subgroup analysis comparing inset techniques for the RC group showed a higher risk of PCF associated with PC (RR, 1.8; 95% CI, 1.1-3.0) and predominately pectoralis myofascial flap with onlay technique (RR, 1.9; 95% CI, 1.2-3.2), but there was no association of pectoralis myocutaneous flap with cutaneous paddle interposition with PCF (RR, 1.2; 95% CI, 0.5-2.8) compared with FTT with cutaneous inset. There were no clinically significant differences in functional outcomes between the groups. In this study of patients with limited pharyngeal defects, interpositional fasciocutaneous closure technique was associated with reduced risk of PCF in the salvage setting, which is most commonly achieved by FTT in academic practices. Closure technique was not associated with functional outcomes at 1 and 2 years postoperatively.

The versatility of the reverse superior labial artery flap

BackgroundThe reverse superior labial artery flap was introduced in 2015 as a reconstructive option for medial cheek defects. Notably, this flap can be redesigned as a more effective repair tool for large facial defect reconstruction. In this study, we redesigned the reverse superior labial artery flap to include the vascular territories of the infraorbital and transverse facial arteries in larger sizes for the repair of large facial defects. MethodsA reverse superior labial artery flap was used to repair large facial defects in 17 patients with a mean age of 74 years. The defects were located in the orbital region and entirely nasal sidewall in patient two, buccal region in patient three, and in lower lip and malar areas in patient five. The flap sizes ranged from 3.5 × 10 to 7 × 15 cm. A sensory examination was performed on the flaps at 6 and 12 months postoperatively. The mean follow-up period was 12 months. ResultsAll flaps survived without partial or total loss. In a small number of flaps minor complications such as venous congestion, epidermolysis, and dehiscence were seen. No functional disability was observed in the lower eyelid or lower lip, and the esthetic appearance was evaluated as satisfactory by the patients. In all the flaps, the protective sensation was recovered in the postoperative 12th month. ConclusionsThe reverse superior labial artery flap has an extensive arc of rotation, a reliable vascular pedicle, and a large cutaneous paddle. Therefore, this flap may be a versatile surgical repair tool for large cheek defects.

Modified tubed anterolateral free flap for reconstruction of total laryngopharyngectomy

Background: A tubed anterolateral thigh (ALT) flap has become a reliable option for laryngopharyngeal defects; however, successful reconstruction remains challenging. Prevention of fistulae, resurfacing of the neck and flap monitoring are key issues that surgeons have sought to address through various flap modifications. Here we describe a chimeric design of the tubed ALT flap which tackles these and other challenges. Methods: Fourteen cases requiring ALT flaps were harvested for reconstruction of total laryngopharyngectomy defects between 2017 and 2019. Each flap was raised on at least two perforators of the descending branch of the lateral circumflex femoral artery (dbLCFA) or both the dbLCFA and transverse branch of the lateral circumflex femoral artery (tbLCFA) to create a chimeric flap. The primary cutaneous paddle was tubed to reconstruct the oesophagus, and the secondary component was inset to the neck as a skin-monitoring paddle. A strip of vascularised vastus lateralis was harvested in the primary paddle continuing with the flap and sutured along the neopharynx suture line, an additional layer preventing anastomotic leak. Results: Patients averaged 61.1 years of age. An average of 2.4 perforators were included per flap. All flaps survived. Donor sites were closed primarily in all cases. Barium swallow was performed in 71.4 per cent of cases (10/14). Fistula occurred in 7.1 per cent of patients (1/14). Patients were followed up for an average of 13 months. Conclusion: Our chimeric ALT free flap design provides a reliable pharyngeal reconstruction, and allows for flap monitoring and neck resurfacing when required, with a low rate of clinically significant leaks or fistula.

Single-stage buried autologous breast reconstruction (BABR)

Breast reconstructive standards are increasingly high oncologically, aesthetically, and practically. Autologous breast reconstruction remains the gold standard which, buried, after nipple-sparing mastectomy (where oncologically safe) or wise pattern reduction for large or ptotic patients, with contralateral symmetrisation where required, enables single-stage reconstruction. However, previous series report prohibitively high revision rates. This series prospectively compares a series of buried and non-buried free flaps for breast reconstruction. All breast reconstructions with free autologous tissue transfer, buried or with a cutaneous paddle, conducted over 8 years by a single surgeon were included. Demographic, oncologic and reconstructive details, immediate complications and revision surgeries were recorded and compared between the two groups. A total of 182 free flaps were performed on 156 patients, 69 buried and 113 with cutaneous paddles. There were no significant demographic or complication differences between the two groups. Of the buried group, 51% did not require further surgery compared to 29% of the paddle group. Buried autologous breast reconstruction is a safe and aesthetic option for breast reconstruction, and potentially single stage. This is particularly true where it is combined with nipple-sparing mastectomy (where oncologically safe) or breast reduction mastectomy, and contralateral symmetrisation, where required. Further research could include patient reported outcome measures and cost analysis.

The Homodigital Propeller Flap: A New Tool for Fingertip Reconstruction. Surgical Technique, Anatomical Study, and Clinical Relevance.

An ideal flap for fingertip injuries should cover a significant loss of substance and avoid joint flexion to prevent later contracture and joint stiffness. In this study, the authors describe a modified homodigital island flap-the homodigital propeller flap-to better meet these requirements. An anatomical model of fingertip loss is used to analyze the advancement achieved without flexion of the finger. Twenty-four fresh-frozen fingers were dissected. Wires were inserted to maintain joints in extension. The skin paddle was similar in location to a homodigital island flap. The neurovascular bundle was dissected without exceeding the proximal interphalangeal joint and was released from the proximal half of the paddle. Then, the homodigital propeller flap was rotated 180 degrees to cover the defect. A mixture of India ink and barium sulfate was injected into the pedicle artery after the release of the proximal half of the flap from the neurovascular pedicle to assess residual flap vascularization. India ink highlights the residual subcutaneous vascularization network of the cutaneous paddle. A radiographic study of the flap was then performed to visualize the subcutaneous vascular network of the cutaneous paddle. The homodigital propeller flap achieved an average cutaneous advancement of 18 mm (range, 15 to 22 mm) and allowed full coverage of cutaneous defects for all fingers while maintaining the proximal interphalangeal joint in strict extension. The homodigital propeller flap is a refinement of the classic homodigital island flap. It allows efficient coverage of fingertip defects because of a large advancement without flexion of the finger, reducing the risk of stiffness.

Intramuscular Near-Infrared Spectroscopy for Muscle Flap Monitoring in a Porcine Model.

Current near-infrared spectroscopy (NIRS)-based systems for continuous flap monitoring are limited to flaps which carry a cutaneous paddle. As such, this useful and reliable technology has not previously been applicable to muscle-only free flaps where other modalities with substantial limitations continue to be utilized. We present the first NIRS probe which allows continuous monitoring of local tissue oxygen saturation (StO2) directly within the substance of muscle tissue. This probe is flexible, subcentimeter in scale, waterproof, biocompatible, and is fitted with resorbable barbs which facilitate temporary autostabilization followed by easy atraumatic removal. This novel device was compared with a ViOptix T.Ox monitor in a porcine rectus abdominus myocutaneous flap model of arterial and venous occlusions. During these experiments, the T.Ox device was affixed to the skin paddle, while the novel probe was within the muscle component of the same flap. The intramuscular NIRS device and skin-mounted ViOptix T.Ox devices produced very similar StO2 tracings throughout the vascular clamping events, with obvious and parallel changes occurring upon vascular clamping and release. The normalized cross-correlation at zero lag describing correspondence between the novel intramuscular NIRS and T.Ox devices was >0.99. This novel intramuscular NIRS probe offers continuous monitoring of oxygen saturation within muscle flaps. This experiment demonstrates the potential suitability of this intramuscular NIRS probe for the task of muscle-only free flap monitoring, where NIRS has not previously been applicable. Testing in the clinical environment is necessary to assess durability and reliability.

Vascularized fibula flap in the management of segmental bone loss following osteomyelitis in children at a Ugandan hospital.

Background: Hematogenous osteomyelitis is commonly observed in the pediatric population across sub-Saharan Africa. This retrospective case series was designed to evaluate the complications and outcomes of treatment using a vascularized fibula flap (VFF) to fill segmental bone defects secondary to osteomyelitis in children in a low-resource setting in CoRSU Rehabilitation Hospital, Uganda. Methods: Clinical notes and radiographs of children with a diagnosis of osteomyelitis that subsequently underwent a VFF procedure between October 2013 and December 2017 were reviewed. All patients were clinically and radiographically evaluated in 2019. Results: Forty-four children, with an average bone defect of 10.5 cm, were included. Eighty-four percent of children had successful VFF limb reconstruction. Integration of the graft was radiologically sound in 20.8 weeks on average. The postoperative phase was uneventful in 29 % of patients. Complications were observed in the remaining patients, including flap failure (6), donor leg neurapraxia (3), cutaneous paddle necrosis (11), graft fracture (2), skin graft loss (6), fixator failure (1) and non-union (2). Functional outcomes were rated as excellent in 13 patients, good in 14, fair in 9 and poor in 8. There was no recurrence of the bone infection in any of the enrolled children. Conclusion: Despite being a complex and demanding procedure, VFF is a good option for reconstructing post-osteomyelitis bone defects, particularly when associated with loss of soft tissue envelope. Considering the more than satisfactory functional and clinical outcomes, this procedure should be kept in mind for these complex pediatric cases of bone and soft tissue loss, even in a low-resource setting.

Thermal imaging for microvascular free tissue transfer monitoring: Feasibility study using a low cost, commercially available mobile phone imaging system.

The use of infrared thermography to evaluate the perfusion of tissue flaps have been studied. This study aims to evaluate the utility of thermal imaging for flap monitoring with a low-cost, readily available smartphone imaging device. Adult subjects who underwent head and neck reconstruction using a microvascular free flap with a cutaneous paddle were recruited. Thermal images were taken of the free flap before, during and after anastomosis. Thermal images were analyzed by measuring the average flap temperature minus the average surrounding tissue temperature (dT). Twenty-one patients were enrolled. The mean dT for flaps intraoperatively prior to anastomosis was -11.47 °F. For 20 patients, dT averaged between -0.30 to 0.12 °F. One flap was inadequately perfused and dT was found to be -4.35 °F. Low cost, mobile smartphone devices such as the thermal camera may provide an objective method of monitoring microvascular free flaps. 2 Prospective Cohort Study.

Reconstructing ‘dual-defect’ pressure sores in spinal patients

Background: Recurrent pressure sores and unstable scars over the bony prominences of the greater trochanter and ischium are a troublesome sequela of spinal injury. A reliable reconstruction is needed for patients with ‘dual-defect’ pressure sores in these locations. We modified the pedicled anterolateral thigh (ALT) flap to fit the reconstructive requirements of ‘dual-defect’ pressure sores.Methods: Eleven consecutive patients with concurrent pressure sores (> grade III) or unstable scar in one of the ‘dual-defect’ areas and an active pressure sore in the other were identified from the Victorian state tertiary referral centre for spinal injuries. We describe the technique and clinical experience of pedicled ALT flaps for reconstruction of ‘dual-defect’ pressure sores in this patient cohort. Preoperative status and minor and major postoperative complications were recorded. Results: Eleven consecutive pedicled myocutaneous ALT flaps were performed for reconstruction of ‘dual-defect’ pressure sores. Several key variations in the anatomical landmarks and the intra-operative flap raise technique that are integral to the use of the ALT flap for this application are described herein. The average dimensions of the cutaneous pressure sore defects were 6 x 4.9 cm (greater trochanter) and 8.2 x 6.7 cm (ischial). The average dimensions of the cutaneous paddle of the flaps raised were 27.3 x 8.4 cm. Two postoperative complications necessitated return to theatre but no incidences of flap loss were recorded. Conclusions: The modified pedicled myocutaneous ALT provides a robust reconstructive solution for resurfacing ‘dual-defect’ pressure sores in spinal patients. Further recommendations for future technical adaptations are made.

Anatomical study of the perforator flap based on the acromial branch of the thoraco-acromial artery (abTAA flap): a cadaveric study.

The aim of this anatomical study was to describe a local perforator flap, for covering shoulder defects, by determining the features of the acromial branch of the thoraco-acromial artery (abTAA), and the supplied cutaneous area. Thirteen fresh cadaveric thoraxes were dissected bilaterally. A precise and reproducible protocol was performed. For each abTAA flap cadaveric dissection, the following parameters were measured after arterial injection: distances between the origin of the perforator artery on the abTAA and the sternum, the acromion, the clavicle, diameter of the perforator artery of the abTAA, length of the perforator pedicle course through major pectoralis muscle, and rotation arc. We also calculated the surface of the injected skin paddle. These measurements were related to morphometric parameters evaluated through the distance between sternum and acromion. The mean distances measured from the origin of the perforator artery on the abTAA were 14.25cm to the sternum, 3.45cm to the acromion, 5.65cm to the clavicle. The mean diameter of the abTAA was 1.20mm ± 0.2. The arc of rotation was 180°, and the length of the perforator pedicle could be extended to 7.46cm ± 1.15. We observed an colored elliptical cutaneous paddle with a longer radius 18cm and a small radius 15cm. Our results suggest that this type of flap could be useful in clinical practice for reconstruction and covering of the acromial area with a thin cutaneous flap with low sequelae on the donor site.

Functional outcome predictors following mandibular reconstruction with osteocutaneous fibula free flaps: correlating early postoperative videofluoroscopic swallow studies with long-term clinical results

BackgroundAdvancements in the field of microvascular surgery and the widespread adoption of microvascular surgical techniques have made the use of osteocutaneous fibula free flaps the standard of care in the surgical management of segmental mandibular defects. Although the literature possesses abundant evidence to support the effectiveness of fibula free flaps as a reconstructive method, there are relatively few studies reporting on outcomes as objectively measured by videofluoroscopic swallowing studies (VFSS). The purpose of this study is to explore the potential correlation between early postoperative VFSS and the long-term swallowing outcomes in patients who underwent mandibular reconstruction with fibula free flaps.MethodsWe performed a retrospective chart review of 36 patients who underwent mandibular reconstruction with osteocutaneous fibular free flaps between 2009 and 2012. Demographics, clinical variables, VFSS data, and diet information were retrieved. Penetration and aspiration findings on VFSS, long-term oral feeding ability, and the need for gastrostomy tube were statistical endpoints correlated with postoperative clinical outcomes.ResultsThirty-six patients were reviewed (15 females and 21 males) with a mean age of 54 years (7–81). Seventeen cases were treated for malignancy. The size of the bony defect ranged from 3 to 15 cm (mean = 9 cm). The cutaneous paddle, a surrogate for soft tissue defect, ranged from 10 to 125 cm2 (mean = 52 cm2). A gastrostomy tube was present in patients preoperatively (n = 8), and postoperatively (n = 14). Seventeen patients had neoadjuvant exposure to radiation. Postoperative VFSS showed penetration in 13 cases (36%) and aspiration in seven (19%). Overall, 29 patients (80.6%) achieved unrestricted diet, and this was statistically correlated with age (p = 0.037), radiation therapy (p = 0.002), and preoperative gastrostomy tube (p = 0.03). The presence of penetration or aspiration on VFSS was a strong predictor for long-term unrestricted oral diet (p < 0.001).ConclusionEarly postoperative VFSS is an excellent predictor for long-term swallowing outcomes in patients undergoing mandibular reconstruction with osteocutaneous fibula free flaps.

Redefining the Anatomic Boundaries for Safe Dissection of the Skin Paddle in a Gracilis Myofasciocutaneous Free Flap: An Indocyanine Green Cadaveric Injection Study.

The gracilis free flap remains a versatile option in the reconstructive ladder. The flap itself can be harvested with or without a skin paddle. The gracilis myocutaneous free flap, however, is known for partial skin flap necrosis, especially in the distal one-third of the skin island. The gracilis myofasciocutaneous flap has been previously described as a technique to improve perfusion to the skin by harvesting surrounding deep fascia in a pedicled flap. However, limitations to this study required injection of multiple pedicles to demonstrate its perfusion. We demonstrate a novel technique using a cadaveric model that shows perfusion through injection via a single dominant pedicle (medial circumflex) with a large cutaneous paddle (average 770 cm2) with included deep fascia, using indocyanine green and near-infrared imaging. For comparison, we are also able to confirm the lack of perfusion to the distal cutaneous paddle when the fascia is not harvested, correlating with previous findings and ink injection studies. This novel technique is versatile, relatively inexpensive, and can demonstrate perfusion patterns via perforasomes that were otherwise not possible from previous techniques. Additionally, real-time imaging is possible, helping to elucidate the sequence of flow into the flap and potentially predict areas of flap necrosis.

La reconstruction du sein avec le lambeau libre de gracilis à palette cutanée transversale (TMG flap)

Breast reconstruction with free flap of gracilis has been described since 2004. The procedure consists in harvesting a flap made of the gracilis muscle and a transverse cutaneous paddle originating from the internal root of the thigh. The pedicle of the flap is the main pedicle of the gracilis muscle. After weaning, the vessels are anastomosed to the internal thoracic artery and vein. The modeling of the breast is done by folding the cut points in front of the muscle to obtain the shape of a cone. This surgical technique allows the realization of autologous breast reconstructions of small to medium size, immediate or delayed, unilateral or bilateral.

Skin Paddles Improve Muscle Flap Salvage Rates After Microvascular Compromise in Lower Extremity Reconstruction.

Free tissue transfer after lower extremity trauma is associated with notoriously high complication rates. Theoretically, the inclusion of a cutaneous paddle on muscle free flaps may improve clinical flap monitoring. The effect of skin paddle presence on muscle free flap salvage outcomes after take-back was examined. Retrospective query of our institutional free-flap registry (1979-2016) identified 362 muscle-based flaps performed for soft tissue coverage after below-knee trauma. Primary outcome measures were perioperative complications, specifically take-back indications, timing, and flap salvage rates. Univariate and multivariate regression analyses were performed where appropriate. The most common flaps were latissimus dorsi (166; 45.9%), rectus abdominis (123; 34%), and gracilis (42; 11.6%) with 90 flaps (24.9%) including skin paddles. Take-backs for vascular compromise occurred in 44 flaps (12.2%), of which 39% contained a skin paddle while 61% did not. Overall salvage rate was 20.5%, with 31.8% partial failures and 47.7% total flap losses. Muscle flaps with skin paddles were more likely to return to the operating room within 48 hours postoperatively than those without (57.1% vs 18.2%, P = 0.036). After take-back, significantly more muscle flaps with skin paddles were salvaged compared with muscle flaps without paddles (35.7% vs 4.5%, P = 0.024). Similarly, more muscle-only flaps after take-back failed compared with their counterparts with skin paddles (95.5% vs 65.3%, P = 0.024). Muscle flaps with a cutaneous paddle were associated with earlier return to the operating room and more successful flap salvage after take-back compared with muscle-only flaps. These findings suggest that skin paddle presence may improve clinical flap monitoring and promote recognition and treatment of microvascular compromise in lower extremity reconstruction.

The Reach of the Gastrocnemius Musculocutaneous Flap: How High Is High?

BACKGROUNDGastrocnemius muscle and musculocutaneous flaps are very versatile and one of the commonly used flaps for lower extremity reconstruction. There is significant literature available on the use of these flaps. However, we feel that the potential of the gastrocnemius musculocutaneous (GMC) flaps has not yet been fully explored in terms of increasing their reach, viability and arc of rotation. An attempt is made to refine the technique of flap harvestation to optimize outcomes of this versatile flap.METHODSSix patients of complex lower limb defects were managed using the GMC flaps. Harvesting of the flap was always initiated from the posterior midline to include the proximal sural pedicle, sural nerve, short saphenous vein and the muscle belly of either the medial or the lateral gastrocnemius muscle along with the cutaneous paddle. All the flaps were islanded and denervated. The origin of the gastrocnemius muscle was detached in all cases to increase the reach of this flap.RESULTSThe flap can reliably and comfortably cover defects from middle third-lower third junction of thigh and the entire posterior aspect of the thigh. Such a local option offers relatively simple but more cost-effective approach to complex clinical problem with tolerable impairment of the donor site. CONCLUSIONThe GMC flap can be considered as a worthwhile alternative to free-tissue transfer for limb salvage.

Fibular osteofasciocutaneous flap in computer-assisted mandibular reconstruction: technical aspects in oral malignancies.

SUMMARYVirtual surgical planning technology in head and neck surgery is witnessing strong growth. In the literature, the validity of the method from the point of view of accuracy and clinical utility has been widely documented, especially for bone modelling. To date, however, with its increased use in head and neck oncology, and consequently the increased need for bone and soft tissue reconstruction, is important to carry out the virtual programme considering not only bone reconstruction but also all aspects related to the reconstruction of soft tissue using composite flaps. We describe our approach to virtual planning in the case of composite flaps. The study reports six consecutive patients with malignant disease requiring mandibular bone and soft tissue reconstruction using fibular osteocutaneous flaps. In all six patients, the resection and reconstruction were planned virtually focusing on the position of cutaneous perforator vessels in order to schedule fibula cutting guides. There were no complications in all six cases. The technique described allowed us to schedule composite fibula flaps in mandibular reconstruction virtually with good accuracy of the position of the bone segment in relation to the cutaneous paddle, important for soft tissue reconstruction. Despite the limited number of cases, the preliminary results of the study suggest that this protocol is useful in virtual programmes using composite flaps in mandibular reconstruction. Further investigations are needed.

Stratégie cutanée dans la chirurgie du lambeau sural et possibilité d’adaptation de cette technique aux autres lambeaux pédiculés

Therapeutic managements in losses of substance of the lower limb using sural flap give an important scar and, sometimes, an impossibility to close the flap donor site. That led us to think about an operative procedure that can reduce those scars without increasing the risk of necrosis of the cutaneous paddle. We present this operative procedure which underwent in the plastic and reconstructive surgery service in our hospital. Classical flap procedure with two cutaneous parts was used. The cutaneous laxity was evaluated so as to close with one cutaneous part; the other cutaneous part was taken and used like a skin graft after the suture of the calf and the formation of a bursa on the donor site. The leg was closed with only one cutaneous flap. This technique is illustrated by a case report. Results at the 4th month are very interesting with an acceptable scar and a good result of the skin graft. However, with this technique, we don't decrease the venous risk of this flap. We used this technique for an antebrachial flap. This technique is an easy and reliable technique based on cutaneous laxity and that decreases scarring of this very useful flap: the neurocutaneous sural flap. We can have a diminution of the number of surgery, a diminution of the scar and good aesthetics results.

Regional Flaps in Head and Neck Reconstruction: A Reappraisal

Starting from our experience with 45 consecutive cases of regional pedicled flaps, we have underlined the effectiveness and reliability of a variety of flaps. The marketing laws as applied to surgical innovations are reviewed to help in the understanding of why regional flaps are regaining wide popularity in head and neck reconstruction. From January 2009 to January 2014, 45 regional flaps were harvested at San Paolo Hospital to reconstruct head and neck defects. These included 35 pectoralis major muscular and myocutaneous flaps, 4 lower trapezius island or pedicled flaps, 3 supraclavicular flaps, 2 latissimus dorsi pedicled flaps, and 1 fasciocutaneous temporal flap. The basic literature of marketing regarding the diffusion of new products was also reviewed. Two myocutaneous pectoralis major flaps were complicated by necrosis of the cutaneous paddle (one complete and one partial). No complete loss of any of the 45 flaps was observed. At 6 months of follow-up, 2 patients had died of multiple organ failure after prolonged sepsis. The 43 remaining patients had acceptable morphologic and functional results. Regional and free flaps appear to compete in many cases for the same indications. From the results of the present case series, regional flaps can be considered reliable reconstructive choices that are less expensive than their free flap alternatives. The "resurrection" of regional flaps can be partially justified by the changes in the global economy and the required adaptation of developed and developing countries.

Functional Outcome Predictors following Mandibular Reconstruction with Free Fibula Flap, Clinical and Videofluoroscopic Correlation

Objectives: Identify outcome predictors by correlating clinical variables with postoperative videofluoroscopic swallow study (VFSS). Methods: Retrospective chart review of 36 patients treated at an academic tertiary center between September 2009 and November 2012. Results: Fifteen females and 21 males with a mean age of 54 years (range 7-81); 17 cases were treated for malignancy. Tongue resection was grouped in 4 categories: no resection (n=6, 16.7%); 0-25% (n=19, 52.8%); 25-50% (n=7, 19.4%) and 50% or more (n=4, 11.1%). The mandibular defect was classified by HCL classification: H (n=6,16.7%); HC (n=2, 5.6%); L (n=8, 22.2%); LC (n=10, 27.8%); LCL (n=10, 27.8%). The size of the bony defect ranged from 3-15cm (mean=9 cm). The flap was osseous only in 10 cases; the cutaneous paddle ranged from 10-125 cm2 (mean=52). A gastrostomy tube was present preoperatively in 8 cases, and postoperatively at least transitorily in 14 cases; X-ray tube (XRT) was used in 17 cases. Postoperative VFSS showed penetration in 13 cases and aspiration in 7. Overall, 29 patients (80.6%) achieved unrestricted diet and this was statistically correlated with: age (p=0.04); XRT (p=0.01); Preoperative G-tube (p=0.12) and penetration or aspiration on VFSS (p=0.01). Conclusions: Age, radiation treatment, preoperative G-tube dependency, and abnormal postoperative swallowing study are predictors for poor functional outcome in patients undergoing mandibular reconstruction with a free fibula flap. Skin paddle size and defect extension/location were not correlated with swallowing outcomes.
