Background: This retrospective study was conducted to compare the outcomes between the free deep inferior epigastric artery perforator (DIEP) flap and the circumflex scapular artery perforator (CSAP) flap in reconstruction of moderate-sized soft tissue defects in the foot and ankle of pediatric patients., Patients and Methods: From January 2004 to December 2016, 42 patients, ranging from 2 to 13 years old, underwent foot and ankle reconstruction, with a free DIEP flap in 21 cases and a free CSAP flap in the other 21cases., Results: All the flaps survived. No marked differences were observed in the demographics, flap size, recipient vessels, and overall early or late complication rate (p > 0.05). The CSAP group had a shorter operation time (134.3 ± 25 min vs. 202.4 ± 24.3 min, p < 0.05) and flap harvest time (29.7 ± 8.1 min vs. 52.2 ± 9.8 min, p < 0.05) than the DIEP group had. In long-term follow-up, the CSAP group showed a lower fat hyperplasia rate (14% vs. 52%, p < 0.05) and better cosmetic outcomes than the DIEP group did (p < 0.05). The functional outcomes had no marked differences (p > 0.05)., Conclusions: The DIEP flap and the CSAP flap are both good options for foot and ankle reconstruction of moderate-sized defects in pediatric patients. The CSAP flap has a shorter operation time and flap harvest time, a lower fat hyperplasia rate, and better long-term cosmetic outcomes than the DIEP flap does., (Copyright © 2019 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

OBJECTIVE. The objective of this video article is to discuss the use of the scapular osteocutaneous free flap in reconstructive procedures. We attempt to discuss normal and variant vascular anatomy, image acquisition via CT angiography, and image interpretation as well as computer-assisted design and manufacturing. CONCLUSION. The scapular osteocutaneous free flap is commonly used for maxillary and mandibular reconstructive surgery. The complex vasculature supplying the scapular region allows flap versatility. There are anatomic variations in the origin of the circumflex scapular and angular arteries. Our method of performing and reporting CT angiography for patients scheduled to undergo scapular osteocutaneous free flap procedures provides a reliable and reproducible means of communicating important elements of vasculature to surgeons. This in turn can facilitate the manufacturing of custom scapular cutting guides and improve surgical outcomes.

Background: Chimeric osteomyocutaneous flaps harvested from the subscapular artery system have been used in clinical practice. We describe the use of a novel circumflex scapular artery myocutaneous and/or vascularized scapular chimeric flap in a rat model and demonstrate optimal skin flap dimensions., Materials and Methods: An 8 × 4-cm-rectangular skin flap based on the circumflex scapular artery flap was harvested, and the mean percentage of the surviving flap area and the necrotic area were calculated to be 71% ± 17.9% and 29% ± 17.9%, respectively. Using flap dimensions determined in the first part of our study, a 4 × 3-cm quadrangular portion of skin was marked over the scapula, and the serratus anterior muscle and a portion of the scapular bone were included in our chimeric flap model., Results: The mean percentages of the surviving flap and necrotic areas were 74% ± 6% and 25% ± 6%, respectively. Microangiographic and histologic studies revealed the vascularity of the skin island and identified the branches of the circumflex scapular artery that supplied the bone and muscle., Conclusions: The circumflex scapular artery myocutaneous and/or vascularized partial scapular chimeric flap may be considered a branch-based chimeric flap and can be an acceptable flap model due to its simplicity, reliability, and consistent vascularity. Furthermore, this flap may have potential applications in studying chimeric flap hemodynamics., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Despite confirmation of a reliable perforasome in the dorsal scapular artery in an anatomic study, a true perforator flap has not been recommended in previous clinical studies because of concerns regarding insufficient perfusion in the distal region. In this report, we present two cases of reconstruction for occipital defects caused by tumor extirpation using pedicled dorsal scapular artery perforator flaps without a muscle component. To secure the perfusion of the dorsal scapular artery perforator flap, inclusion of an additional perforator was attempted for perfusion augmentation. The second dorsal scapular artery perforator was harvested in one case. In an additional case, the sixth dorsal intercostal artery perforator with a branch that directly connected with the dorsal scapular artery within the trapezius muscle was additionally harvested. The flaps survived without any perfusion-related complications, including tip necrosis, and no donor site morbidities were observed. We suggest that a perfusion augmented dorsal scapular artery perforator flap by harvesting multiple perforators could be a safe and useful alternative for reconstructive surgery of head and neck defects., (© 2014 Wiley Periodicals, Inc.)

The reconstruction of oromandibular defects associated with extensive loss of external skin is surgically challenging. We describe 2 cases where such defects were reconstructed with a chimeric thoracodorsal artery perforator and scapular (TDAP-Scap) free flap based on the subscapular system. The flap is a reliable option in the reconstruction of through-and-through oromandibular defects., (Copyright © 2015. Published by Elsevier Ltd.)

This report describes a case of a patient who underwent secondary reconstruction of the maxilla using a combined scapular osseous and thoracodorsal artery perforator (TAP) flap, in which the pedicle of the scapular osseous flap was lengthened by reconnecting the angular branch of the thoracodorsal artery to the serratus branch. The patient was a 62-year-old man who had undergone left total maxillectomy for maxillary carcinoma and came for reconstruction of left deformity. A reconstructive procedure involving a vascularized scapular osseous and TAP flap transfer was planned. However, the patient's ipsilateral superficial temporary artery and facial artery was found stenosed due to previous radiotherapy and chemotherapy and were not suitable for use as recipient vessels. Thus, a long flap pedicle was needed for anastomoses to the contralateral recipient vessels. We lengthened the pedicle of the scapular osseous flap by reconnecting the angular branch of the thoracodorsal artery to the serratus branch within the chimeric free flap and then anastomosed it to the contralateral facial vessels. The postoperative course was uneventful, and the left cheek deformity was well corrected. Using the technique of reconnection of branches within the blood supply system, a chimeric flap with a long pedicle may be elevated safely whilst avoiding the need for vein grafts., (© 2014 Wiley Periodicals, Inc.)

Objective: To explore a surgical model of utilizing consecutive free scapular flap and adjacent pedicled flap transfer for repairing massive soft tissue defects on the dorsum of the hand while minimizing the donor site morbidity., Methods: Six patients with massive soft tissue injuries on the opisthenar and forearm were treated with free scapular flaps. Afterwards, a pedicled flap adjacent to the donor site was transferred to cover the donor site defect by direct closure., Results: All six free scapular flaps survived without signs of infection. Three adjacent pedicled flaps presented minor signs of insufficient blood flow on the distal apex, which resolved after six weeks with only conservative therapy. All the incisions healed without other complications. At six-month follow-up, the patients regained full shoulder function., Conclusion: With the assistance of an adjacent pedicled flap, the scapular flap is a highly applicable approach in repairing massive soft tissue defects in the opisthenar. It can achieve positive outcomes in both reconstructive and aesthetic aspects.

Background: In addition to prosthetic rehabilitation, maxillary defects can also be surgically reconstructed. Soft-tissue reconstruction employs a radial forearm or latissimus dorsi muscle flap, while bony reconstruction can be achieved using a fibula, iliac crest, or scapular flap. Reconstruction using a scapular flap is further divided into two subgroups: the traditional scapular flap with the circumflex scapular artery as the donor vessel and the scapular angle flap with the angular artery originating from the thoracodorsal artery as the donor vessel., Materials and Methods: We report on four patients who underwent successful reconstruction with a free scapular angle flap between 2009 and 2011, following maxillary resection due to malignancy., Results: Vertical positioning of the scapular angle flap enables reconstruction of the facial contour, whereas its horizontal alignment and microvascular anastomosis makes a bony reconstruction of the hard palate possible., Conclusions: The versatility, low rate of donor site morbidity and shape of the scapular angle flap--which resembles that of the hard palate--render it ideal for plastic reconstruction. The suitability of bone quality for dental rehabilitation with implants is a topic of controversial discussion. The scapular angle flap represents an alternative to obturator prosthesis for the reconstruction of maxillary defects ≥ grade I according to Okay et al.

Introduction: The scapular, parascapular and thoracodorsal artery perforator (TDAP) flaps represent fasciocutaneous flaps derived from the subscapular artery axis. These flaps can be harvested individually or combined as conjoint flaps, tailored to reconstruct a wide variety of defects in the extremities. ANALYSIS AND METHODS: All patients undergoing free-flap reconstruction at North Bristol trust with a fasciocutaneous flap of the subscapular axis from April 2006 until April 2010 were included. This cohort of 45 patients was retrospectively analysed. The Enneking score for return of limb function was used as an outcome measure after reconstruction. Donor-site morbidity analysis was carried out prospectively using Oxford Medical Research Council (MRC) score, Vancouver Scar Scale and disability of arm, shoulder and hand questionnaire (DASH) scores., Results: A total of 45 patients had extremity reconstruction using flaps of the subscapular artery axis following severe limb trauma, often comprising open tibial fractures. A total of 42 patients had lower limb injuries and three had upper limb injuries. All flaps survived. The mean Injury Severity Score (ISS) was 9.3, the mean Enneking score was 27 at 12 months mean follow-up. In the nine conjoint flaps, the mean area of tissue resurfaced was 257 cm2., Conclusions: In this case series of fasciocutaneous flaps of the subscapular artery axis, we establish that these flaps are robust and versatile. They replace 'like-with-like' and have good patient satisfaction. The donor site can be closed primarily, is discrete and has minimal donor morbidity. The conjoint flaps can be used for reconstruction of very large defects without the need to sacrifice functionally important muscle., (Copyright © 2012 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Conservation laryngeal surgery has been limited by difficulties with partial resection of the cricoid. Numerous options have been suggested that include temporoparietal flaps, free cartilage grafts, radial forearm free tissue transfers, and tracheal autotransplantation with vascular carriers. The authors present a one-stage procedure for the reconstruction of the cricoid cartilage based on the thoracodorsal artery scapular tip (Tdast) autogenous transplant that uses the curved tip of the scapula and does not create a secondary tracheal defect. Because the Tdast is a vascularized graft it may withstand radiation treatment., (Copyright © 2011 The American Laryngological, Rhinological, and Otological Society, Inc.)

Objectives: The purpose of our study was to evaluate the results of the reconstruction of the lower extremity defects with free flaps based on the subscapular artery., Methods: Between January, 1998 and December, 2008, 51 patients (mean age 26 years; 16 female and 35 male) presenting with a lower extremity defect underwent a reconstructive surgery with flaps based on the subscapular vascular system. Thirty-seven percent of the defects were located in the crus, 19% in the sole, 16% in the heel, and 14% in the dorsum of the foot. Eighty and a half percent of the patients had traffic-accident-related and 13.5% had burn-related tissue defects., Results: Fifty-three percent of the patients presenting with lower extremity defects underwent reconstruction with latissimus dorsi muscle flaps, 21% with free serratus muscle and/or fascia flaps, 14% with free parascapular fasciocutaneous flaps, and 12% with free combined latissimus muscle and serratus muscle and/or fascia flaps. Anastomoses of 80% of the patients were performed on their posterior tibial artery and accompanying veins and/or foot dorsal veins. End-to-end anastomosis was performed on 14 patients, while 35 patients received end-to-side anastomosis. Six patients were treated with cross free flaps, of which 4 received cross latissimus, 1 cross serratus, and 1 cross combined serratus and latissimus flaps. End-to-side anastomoses were performed on these patients on the cross-leg tibialis posterior artery. The cross-leg anastomosis was freed 4 weeks later. In the early period, venous occlusion was observed in 4 patients and arterial and venous occlusion was present in 1 patient. New anastomoses were performed in these patients. Partial necrosis was observed in 2 patients. The average follow-up period was 61 months. Pressure-related late ulcerative lesions developed in 4 patients. The lesions of these patients were repaired by debridement and primary suturing or partial thickness skin grafts., Conclusion: The subscapular vascular system based flaps have an optimal vascularity once they are prepared with adequate pedicles, causing minimal donor site morbidity. These flaps are a safe and effective alternative in lower extremity reconstruction. On the other hand, in the absence of appropriate recipient vessels, single or combined cross-leg free flaps may provide successful repair.

Mandibular and maxillary resections can produce complex three-dimensional defects requiring skeletal, soft tissue, and epithelial reconstruction. The subscapular vascular axis offers a source of skin, bone, and muscle on a single pedicle for microvascular flap transfer. We reviewed four cases where the subscapular vascular pedicle was used as a source of tissue for complex facial reconstructions in maxillofacial defects. Reconstruction of these complex defects was performed with a latissimus dorsi muscle or myocutaneous flap in combination with the lateral border of the scapula, harvested on the angular branch of the thoracodorsal vessels. There were three cases of maxillectomy and one case of partial mandibulectomy for malignant tumors. In each case, the angular branch of the thoracodorsal artery supplied 6 to 8 cm of the lateral border of the scapula and a latissimus dorsi myocutaneous flap was used for soft tissue reconstruction. Follow-up ranged from 9 months to 3 years and in all cases there was successful bony union. Shoulder movement was normal. This series encourages the further use of subscapular axis flaps as flexible sources of combined myocutaneous and osseous flaps on a single vascular pedicle in cases of complex maxillofacial reconstruction., ((c) Thieme Medical Publishers.)

Unlabelled: Free tissue transfer has become the dominant reconstructive tool for segmental defects of the mandible, except in case of severe peripheral vascular disease. In these cases, we propose to use the osteomuscular dorsal scapular (OMDS) flap as an alternative technique. This flap is pedicled on the dorsal scapular vessels with the harvesting of the medial border of the scapula and the lateral part of the rhomboid muscles., Methods: Thirteen cadaveric dissections have been performed after arterial injection of coloured latex in order to describe the surgical landmarks of the dorsal scapular pedicle. Six patients have been operated after lateral resection of the mandible., Results: The mean length of the pedicle was 66 mm (+/-2.61). The pedicle was located 41.2 mm (+/-5.51) lateral to the superior angle and 24.6 mm (+/-7.50) lateral to the medial angle. The size of the medial border that could be used for mandibular reconstruction was 116.4 6 mm (+/-7.48). The width of the medial border was 2.62 mm (+/-0.77) on the upper part and 3.35 mm (+/-0.90) on the inferior part. The clinical results were satisfying; good symmetry of the mandible was restored with normal opening of the mouth. Normal elevation of the shoulder was retained without recourse to physiotherapy., Discussion: The advantages of this method over other pedicled flaps include the length of the bone that can be harvested (>12 cm) allowing reconstruction of defects from the condylar process to the canine region and the preservation of scapular elevation. The superior part of the trapezius was not harvested, in order to allow passage of the flap in the tunnel under the upper trapezius to preserve the scapular elevation. The main disadvantages of the OMDS flap are the impossibility of placing implants in the bone that have been harvested because of its thickness and the lateral position that has to be changed to supine to allow access for resection of the tumour., (2008 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

The fibula free flap has become the dominant free flap for all mandible reconstructions, except in case of severe peripheral vascular disease. In these cases we propose to use the pedicled osteo-muscular dorsal scapular flap as an alternative technique. This flap is an original technique, it is pedicled on the dorsal scapular vessels with harvesting of the medial border of the scapula and the lateral part of the rhomboid muscles. We carried out an anatomic study of the scapular region on 33 subjects in order to describe the surgical landmarks of the dorsal scapular pedicle. We determined the feasibility of this technique using a ten fresh cadavers and performed this flap on three patients. In most cases (58%), the dorsal scapular artery passed very close to the superior angle of the scapula and ran lateral to the medial border of the scapula, in 42% of cases the artery divided into a lateral branch which stayed deep to the medial border of the scapula and a medial branch which ran deep to the rhomboid muscles. In all cases an anastomosis between the dorsal scapular artery and the descending branch of the transverse cervical artery was present. In this technique, after harvesting the medial border of the scapula and the lateral part of the rhomboid muscles, the flap has been transposed in the cervical region through a tunnel under the superior part of the trapezius. This technique has been used in three patients after lateral resection of the mandible. The functional results were good, allowing the preservation of the scapular elevation.

Purpose: Wide palatomaxillary defects, mostly after tumor resections, can cause severe functional and esthetic problems. Although prosthetic obturator devices or local flaps are mostly adequate for uncomplicated small-size defects, free flaps are preferred for a 3-dimensional multitissue reconstruction of more complicated defects. Regarding the anatomical structure of the palatomaxillary region, the flap must be thin enough to separate the oral and nasal cavities while not compromising palatal function, yet rigid enough for adequate dental restoration. This goal is usually accomplished with a combined or complex free flap. Numerous free flaps containing both soft tissues and bone have been described in the literature. In this study, we present a novel use of the free scapular bone flap combined with serratus anterior fascia and its functional and esthetic results., Patients and Methods: Nine cases are presented whose wide composite palatomaxillary defects were repaired with free angular scapular bone flap combined with serratus anterior fascia based on the subscapular vascular system, between 1999 and 2003. Scapular bone wrapped with the naked serratus anterior fascia, like a sandwich, was used to repair the palate., Results: The naked fascia was epithelialized with the help of the surrounding mucosa in 4 to 6 weeks. Results were satisfying with regard to breathing, eating, speech, and facial contour after follow-ups for 2 months to 6 years., Conclusion: For the reconstruction of wide palatomaxillary defects, a combined flap of angular scapular bone wrapped with naked serratus anterior fascia was conceived useful for obtaining satisfactory functional and esthetic results.

The development of microsurgery has most recently been focused upon the evolution of perforator flaps, with the aim of minimising donor site morbidity, and avoiding the transfer of functionally unnecessary tissues. The vascular basis of perforator flaps also facilitates radical primary thinning prior to flap transfer, when appropriate. Based upon initial clinical observations, cadaveric, and radiological studies, we describe a new, thin, perforator flap based upon the circumflex scapular artery (CSA). A perforator vessel was found to arise within 1.5cm of the CSA bifurcation (arising from the main trunk, or the descending branch). The perforator arborises into the sub-dermal vascular plexus of the dorsal scapular skin, permitting the elevation and primary thinning of a skin flap. This thin flap has been employed in a series of five clinical cases to reconstruct defects of the axilla (two cases of hidradenitis suppurativa; pedicled transfers), and upper limb (one sarcoma, one brachial to radial artery flowthrough revascularisation plus antecubital fossa reconstruction, and one hand reconstruction with a chimeric flap incorporating vascularised bone, fascia, and thin skin flaps; free tissue transfers). No intramuscular perforator dissection is required; pedicle length is 8-10cm and vessel diameter 2-4mm. There was no significant peri-operative complication or flap failure, all donor sites were closed primarily, patient satisfaction was high, and initial reconstructive aims were achieved in all cases. Surgical technique, and the vascular basis of the flap are described. The thin circumflex scapular artery perforator flap requires no intramuscular dissection yet provides high quality skin (whose characteristics can be varied by orientation of the skin paddle), and multiple chimeric options. The donor site is relatively hair-free, has favourable cosmesis and no known functional morbidity. This flap represents a promising addition to the existing range of perforator flaps.

Microvascular iliac crest and scapula transplants have been used in reconstruction of the lower jaw following tumor surgery. It has only been with the insertion of dental implants that a satisfactory prosthetic rehabilitation of the patient has been achieved. For this study, a follow-up of 38 patients with lower jaw tumors was carried out. The patients had been treated with partial resection of the lower jaw and neck dissection with microvascular iliac crest transplants (n = 20) or microvascular scapula transplants (n = 18); this was followed with dental implants (n = 143) in the region of the transplants or the local lower jaw. One hundred thirty-nine of the 143 dental implants were loaded by prosthetic superstructures. In all patients, the implant situation was evaluated on average 2 years 5 months after implantation. Periotest values, periimplant probing depths, and contact bleeding were registered, and the extent of periimplant bone loss was defined radiographically. The clinical situation in the region of the implant was compared for both types of implants and also with the nonresected lower jaw. The average Periotest values were within the normal range for all groups. In one scapula implant, however, a better average of Periotesting, -3.3, was found compared with implants of the iliac crest with Periotest values of -0.7. A measurement of -2.1 was found for the local lower jaw, similar to that of scapula implants. Pathologic probing depths were found for all three compared groups. The radiographically determined vertical loss of bone was the same for all three groups, on average 1 mm at 27 months postoperatively. The highest incidence of sulcus bleeding was found in the scapula implant group. Thus, it can be stated that the scapula transplants provide a similar transplant site to local lower jaw bone, whereas implants in iliac crest transplants show lesser bony stability. Periimplant soft-tissue conditions are worse for both types of transplants compared with local tissue of the lower jaw.

The authors present their experience of 27 cases with repairs of defects following radical maxillectomies with free flaps. A total of 28 flaps were used (five latissimus dorsi, six scapula, 16 combination flaps of scapula and latissimus dorsi and one combination of scapula, latissimus dorsi and serratus anterior flap). Only one scapula flap was completely lost and in three cases where a combination of scapula and latissimus dorsi flap was used, partial necrosis of one component occurred. The authors first choice for reconstruction is a scapula bone flap raised on the angular artery combined with the latissimus dorsi flap. The combination of flaps with a long pedicle and of the bony and muscular components provides the surgeon with the option of customizing the flap to meet individual patient needs. For intraoral closure the authors prefer the latissimus dorsi muscle which rarely requires secondary procedures for prosthesis placement following epithelialization and atrophy. The main disadvantage of the flap is the difficulty of two teams working simultaneously, thus increasing the average operating time. All postoperative corrections and prosthetic rehabilitation should be postponed for at least 2 months following surgery because of postoperative swelling., (Copyright 2000 European Association for Cranio-Maxillofacial Surgery.)

Purpose: This study evaluates contour restoration in segmental defects of the mandible and the survival rate of endosseous implants placed into these reconstructions., Patients and Methods: Forty-four patients with 23 nonvascularized grafts and 21 patients with vascularized bone flaps were included in the study. The lateral and the sagittal extension of the contour of both the mandibular bone and the overlying soft tissues was determined from serial computed tomography (CT) scans in defined planes through the reconstructed mandible. The success rate of dental implants was determined by a life-table analysis., Results: Average lateral deviation of the reconstructed side from the nonreconstructed side was 4.3 mm (nonvascularized grafts) and 5.6 mm (vascularized grafts). The soft tissue contour followed the skeletal contour quite closely, with slightly smaller degrees of deviation. Asymmetry was greatest in the area of the horizontal ramus. In some cases, skeletal deviation was intentionally produced to compensate for a soft tissue deficit on the reconstructed side. However, in some cases, a major deviation of bone contour was associated with considerable deviation of the soft tissue contour (maximum, 10.5 mm). The cumulative implant success rate was 100% after 5 years and 60.3% after 10 years. None of the seven implant failures accounted for prosthetic failure., Conclusions: Although there are minor differences, both nonvascularized and revascularized grafts allow for satisfactory contour restoration in segmental reconstructions of the mandible. Implants placed into these grafts provide a reliable basis for dental rehabilitation.

One-stage reconstructions of complex or unusually large defects frequently require composite tissue transfers. The various components of these "chimeric" flaps facilitate three-dimensional reconstructions or the coverage of large surface defects. Data from 36 combined flaps from the subscapular arterial system are demonstrated in this series. Defect locations were evenly distributed between the upper and lower extremities. Eighty-three percent were two-component flaps, and 17 percent contained three or more various tissue components. Overall flap survival was 97 percent. Major complications included vascular revisions in four patients and seven secondary skin transplantations. Five cases contained osseous components. The independent mobility of skin, muscle, and bone proved to be a major advantage in the reconstruction of compound defects. Donor-site morbidity was acceptable; the most frequent donor-site complication was persistent seroma in 9 of 36 patients (25 percent). Patient satisfaction was high. Ninety-one percent were satisfied with the operative result and would undergo the operation again. Eighty-six percent accepted the aesthetic appearance of the donor site. The data demonstrate that these complex flap procedures are extremely reliable and versatile, thus avoiding multiple reconstructive procedures and achieving excellent reconstructive results with acceptable donor-site morbidity.

Large palatomaxillary and oromandibular defects have a dramatic impact on speech, deglutition, mastication, and cosmesis. Traditional methods of reconstruction, such as locoregional flaps, free bone grafts, alloplastic materials, and prosthetic devices, have difficulty providing meaningful aesthetic and functional reconstruction of these defects. This article discusses current concepts in the reconstruction of large composite palatomaxillary and oromandibular defects with an emphasis on the role of free tissue transfer, including the factors to be evaluated when choosing a method of reconstruction, indications for specific donor sites, and recent technical refinements.
