Jackson, presents a simple, elegant approach to solving common reconstructive problems encountered by plastic surgeons at all levels of training.In the second volume, Microsurgical Reconstruction of the Head and Neck, Drs. A patient with T4aN0M0 left floor of mouth SCC status post pectoralis rotational flap and surgical bar reconstruction. The initial baseline posttreatment PET/CECT is performed 10–12 weeks after the end of radiation treatment, or after the operation, to allow posttreatment changes to resolve. The patient was lost to follow-up for 2 years and then presented with a 1-month history of hardware exposure with a large area of exposed mandibular hardware (arrow) on axial CECT (A) and clinical examination (B). Like rectus FFs, they can fill large defects. Final pathology results were benign skeletal muscle and fibroadipose tissue, consistent with focal inflammation; no malignant cells were present. Rectus abdominis FFs include one of the paired vertically oriented ventral abdominal muscles.5,20 They are especially advantageous because of the versatility of flap design and the length of the associated vascular pedicle, up to 10–15 cm long. Axial fat-saturated T1 postcontrast MR imaging (A) demonstrates the T4a left lateral oral tongue SCC (asterisk), which also involved the extrinsic tongue muscles and floor of mouth. A patient with fibular FF following right mandibulectomy for T2N1 SCC of the mandibular gingiva returned 8 weeks after the operation with a palpable right-neck mass. Probably the main impact of perforator flaps in the head and neck region is to increase the sophistication of our reconstructions as well as to provide us with more choices. A free flap is a graft of human tissue which is taken together with its supplying blood vessels and placed in another part of the body where it … Any of the segments can be fashioned to reconstruct the hard palate or orbital rim. The fatty portion of the flap should be relatively homogeneous without induration, nodularity, or abnormal focal enhancement (Fig 11). The rectus muscle (thin arrow) lines the skull base defect, while a portion of the skin paddle recreates the oral cavity mucosal surface (curved arrow). Scapular osteocutaneous FF. Local and Regional Flaps in Head & Neck Reconstruction: A Practical Approach provides comprehensive, step-by-step instruction for flap raising and insetting for the head and neck region. Axial postcontrast fat-saturated T1 MR image (C) shows the FF muscular thin, non-nodular enhancement (block arrow), similar to that in other muscles in the H&N. FF Infection. In patients with H&N cancer with a history of radiation therapy or a recent operation, unless baseline postoperative studies are available, it may be impossible to distinguish infection from treatment-related changes solely on the basis of imaging alone. Lees er meer over in ons, Free Flaps in Head and Neck Reconstruction, Tot 40% korting op dameskleding, schoenen en accessoires*, Bezorging dezelfde dag, 's avonds of in het weekend*. Fasciocutaneous FFs can be used to restore skin or mucosal defects (Fig 4). Despite the complexity and increasing frequency of free flap reconstruction, there is no comprehensive head and neck resource intended for the radiologist. In addition, it discusses microvascular techniques and explores different soft-tissue, perforator and bone flaps, including novel free tissue flaps, presented for the first time in the head and neck field. The ALT has a large, thin, pliable skin paddle with relatively little morbidity at the donor site. The interface of the flap and resection cavity, known as the recipient bed, is the most critical area to examine because this is the site of local disease recurrence. Axial flaps are typically considered more reliable than random flaps on the basis of improved distal perfusion. Be sure the plate has not elevated from the bone and that the screws maintain the plate, without periscrew lucency, which would imply loosening or infection. Multiplanar reformations are also sent to the PACS. MR imaging protocols vary depending on the location of the abnormality. In contrast, axial flaps are supplied by a specific arteriovenous system. Vascular pedicle ossification. betaal facturen of The recipient site margins (short arrow) have no nodularity. Note stranding in the fatty flap (block arrow), compared with the homogeneous fat density in the lateral flap that reconstructed the buccal mucosa (star). This richly illustrated atlas provides a clear and comprehensive step-by-step description of surgical techniques for raising and setting free flaps from different donor sites, to reconstruct damage to the head and neck caused by cancer and trauma. The latissimus is fastened to secure the mandible and recreate the mylohyoid sling. Radiologists will encounter cross-sectional imaging studies performed to evaluate postoperative complications in patients with FF. Houd er rekening mee dat het artikel niet altijd weer terug op voorraad komt. Head & Neck. Examples of local flaps include rotation, advancement, and transposition. There are many techniques that can be used to reconstruct the head and neck. 2007;29:285-91 Chapter 5 Infrahyoid flap reconstruction of oral cavity and oropharyngeal 47 defects in elderly patients with severe general comorbidities Deganello A, Gitti G, Parrinello G, Larotonda G, Meccariello G, Leemans CR, Gallo O. A variety of different bone shapes can be obtained depending on the contour of the defect. Ook willen we cookies plaatsen om je bezoek aan bol.com makkelijker en persoonlijker te maken. Free flap reconstruction is a cornerstone in the man-agement of many head and neck cancers. Visceral FFs can be used in pharyngoesophageal reconstruction. Muscular flap components are usually striated, thin, and relatively flat (Fig 11). However, not all patients are suitable candidates for free flap reconstruction. Most patients with advanced head and neck cancers now undergo microvascular free flap reconstruction following oncologic resection as part of their comprehensive treatment since it facilitates complete tumor removal by providing very reliable wound coverage with generally better restoration of function and cosmesis than local and regional flaps.1, 2 However, despite aggressive surgical resection … Multiple clips are usually present at the vascular pedicle, denoting the anastomosis between the flap and resection cavity, but they are small and rarely degrade image quality. Considerations included myositis, denervated muscle, or recurrent intramuscular tumor. Different segments of the bone can be harvested, including the scapular tip and up to 2 segments of the lateral border. The tubular shape and thick cortical bone make the fibular FF particularly strong. Door op ‘accepteren’ te klikken ga je hiermee akkoord. This book offers invaluable insights into free-flap harvesting and transferring techniques for both residents and experienced specialists in the field of otolaryngology, head and neck, maxillo-facial and plastic surgery. The jejunal FF is especially useful given its similar in caliber to the esophagus (Fig 9).16 The pharynx is a larger caliber than the jejunal FF; thus, the cephalad border of the flap may be opened along the antimesenteric border to achieve a more suitable anastomosis.5 For circumferential pharyngeal defects, jejunal and ALT FFs have slightly better functional outcomes than radial forearm FFs.23. The radial forearm FF has a rich vascular supply and may be harvested in a variety of sizes. Submit a Manuscript; Information for Authors; Language Editing Services; Author Permissions; Journal Info. An additional distinction with regional and free flaps is that they may be of simple or composite design. Onze klantenservice This richly illustrated atlas provides a clear and comprehensive step-by-step description of surgical techniques for raising and setting free flaps from different donor sites, to reconstruct damage to the head and neck caused by cancer and trauma. This vascular pedicle length allows the surgeon to inset rectus FFs into almost any H&N defect, even those a distance away or on the opposite side of the head and neck from the vascular anastomoses. 5-7 Our hypothesis was based on the assumptions that patients receiving free flaps would have more advanced disease, more drains placed and for longer periods, and longer procedure times compared with patients not receiving free flaps. Surgical flaps and surgical grafts are both used in H&N reconstruction. Osteonecrosis is treated surgically, while osteomyelitis will usually be treated medically. Following laryngopharyngectomy, the intraoperative photograph (A) shows a segment of the jejunum (arrow) interposed between the oropharynx and esophagus, anastomosed end to end to allow patients to eat and swallow. Preoperative axial CECT (A) shows a T4a maxillary sinus SCC. Intraoperative goal‐directed vasopressor administration during head and neck free flap reconstruction does not appear to increase the rate of flap complications or failures. Fig. Alle prijzen zijn inclusief BTW en andere heffingen en exclusief eventuele A CECT of the neck with the arms down is performed following PET, using a split-bolus technique with 110 mL of intravenous iopamidol (Isovue-370; Bracco, Princeton, New Jersey), with 55 mL injected first at 2.5 mL/s, a 40-second delay, then another 55 mL at the same rate, and a total scan delay of 90 seconds. Surgeons now use microvascular free tissue transfer, also known as free flaps, more frequently in head and neck reconstruction than ever before. Jejunal FF. en © 2021 by the American Society of Neuroradiology | Print ISSN: 0195-6108 Online ISSN: 1936-959X. The pectoralis myocutaneous flap was considered the “workhorse” flap of head and neck reconstruction during the 1970s. On CECT, the flap muscle is isodense to striated muscle elsewhere. Posttreatment H&N clinical and imaging follow-up is complex, even more so when the resection site is reconstructed. Each donor vascular pedicle is transected at the donor site, transferred along with the flap constituents to the primary defect, and inset at the primary defect. Local and regional flaps in head and neck reconstruction Slideshare uses cookies to improve functionality and performance, and to provide you with relevant advertising. This review article focuses on free flaps, summarizing what defines an FF, those most commonly used, the expected postoperative imaging appearances, and associated complications. This flap is easy to harvest and versatile. Conclusions. verzendkosten With respect to defect proximity, flaps can be classified as local, regional, or free (Fig 1). Primary site recurrences most often occur at the margins of the resection at the flap–native tissue interface and have nodular or masslike enhancement with signal characteristics similar to those of the original tumor (Fig 12).37⇓–39 Nodal recurrence may have the typical expected regional distribution of the original tumor or may vary from the norm due to surgical alteration of drainage pathways.28 The third recurrence pattern is perineural spread of disease. r head and neck reconstruction. Thus, performing an accurate preoperative Allen test is of the utmost importance to ensure an adequate supply of the hand via the ulnar artery and to avoid catastrophic ischemia of the hand.5, The anterolateral thigh (ALT) FF has a large, thin, pliable skin paddle and a long vascular pedicle, up to 15 cm. Following maxillectomy and orbital exenteration with ALT FF reconstruction, the patient had a biopsy-proved recurrence (white arrowheads) at the margins of the ALT FF on postoperative CECT (B) several months later. The bone should be well-corticated without erosion or destruction. An organized approach to postreconstruction imaging interpretation helps make a complex study easier to understand (Table 3). An organized approach and thorough understanding of FF appearances and complications will help interpreting radiologists provide accurate, useful imaging reports for both the patients and their referring clinicians. Tubed radial forearm FF. Thus, for radiologists, it is useful to categorize free flaps by the dominant donor tissue constituents (Table 1), creating 4 main categories: muscular, fascial, osseous, and visceral FFs.17, Surgical free flaps in head and neck reconstruction, Surgical approach to free flaps in H&N reconstruction, This simplified approach has important facts to note. Als we je account op een ander apparaat herkennen, hoef je niet opnieuw de keuze te maken. They conducted a retrospective review of all lateral forearm flap reconstructions performed between 2016 and 2018. Local flaps, flaps generated adjacent to the primary defect, are examples of random flaps. Conversely, the major graft vasculature is transected at the donor site and the tissue inset without vessel-to-vessel anastomosis. Similar to the radial forearm FF, ALT reconstruction can be used for skin and mucosal lining defects, subtotal glossectomy defects (Fig 6), pharyngeal defects, and skull base defects. Adopting a very practical approach, this illustrated atlas provides step-by-step description of surgical techniques for free flap raising to reconstruct damage to the head and neck caused by cancer and trauma by describying the indications and technical aspects of each single procedure needed Grafts may be autograft (from the patient), allograft (from a donor, often cadaveric), or alloplastic (man-made). Additionally, some FFs (rectus abdominis and latissimus dorsi) may be harvested as either myocutaneous or fasciocutaneous. Although we are grouping these by the dominant tissue type, most of these FFs also contain skin paddles that reconstruct both skin and mucosal surfaces because both should be reformed with epithelial tissue. Hardware exposure. Swallowing and diet were assessed in patients undergoing intraoral reconstruction. Je kunt je cookievoorkeuren altijd weer aanpassen. In our practice, the first posttreatment contrast-enhanced CT (CECT) is performed with PET to increase detection of persistent tumor, nodal, or distant metastases and to differentiate residual tumor from non-neoplastic postoperative changes. ALT FF intraoperative image (C) shows the harvested FF on the operating room back table with an elongated vascular pedicle (arrowhead). Surveillance for tumor recurrence is the main focus of follow-up imaging. This entity presents in patients with fibular FF as a thin, linear, or curvilinear ossific density following the course of the vascular pedicle (Fig 16), the result of ossification of a strip of periosteum inset with the vascular pedicle. SUMMARY: Head and neck surgical reconstruction is complex, and postoperative imaging interpretation is challenging. FFs are unfortunately frequent today as >675,000 patients worldwide are diagnosed with H&N cancer annually.6. One or 2 skin paddles may be harvested, allowing a variety of uses, such as floor of mouth reconstruction (Fig 3) or large skull base defects.5,7. Osseous-containing FFs are some of the most complex FFs. They have better functional outcomes and cosmetic restoration than surgical grafts and other types of surgical flaps (local and regional).1⇓⇓–4 Since free flaps were first used in the 1970s, surgeons have expanded their repertoire, fine-tuned techniques, and improved outcomes.5 While FFs may be used to reconstruct defects from infection, trauma, and osteonecrosis, they are most often used following tumor extirpation. Sagittal postoperative CECT (B) shows the jejunal FF neopharynx (block arrow). Extensive dissection toward feeding vessels of flap near the parasternal area is avoided. is dag en nacht open. If you continue browsing the site, you agree to the use of cookies on this website. One or 2 skin paddles may be harvested; one usually recreates the oral mucosal surface as shown in the diagram. Ischemia of FFs may be due to either venous or arterial thrombosis.8 The surgical team is on high alert for signs of FF ischemia in the immediate postoperative period. However, the muscle itself is one of the thinnest in the body. Om bol.com voor jou nog beter te maken, gebruiken wij altijd functionele en analytische cookies (en daarmee vergelijkbare technieken).
