Free microsurgical tissue transfer of the latissimus dorsi flap may be indicated for the restoration of intra- and extraoral defects, especially when a large-sized skin island flap is required. In many cases, use of the latissimus dorsi flap for coverage of large-sized intraoral defects results in bulkiness due to the proportion of subcutaneous fat. Prelamination of free flaps appears to be a promising technique to overcome this flap bulkiness. This modification in flap design could improve the postoperative functional outcome, as well as reduce donor site morbidity. This article presents four novel clinical cases, in which the patients underwent prelamination of the latissimus dorsi flap with local skin grafts during oral cancer treatment in order to reduce the thickness of the free flap and allow tension-free primary closure of the donor site. These attempts successfully covered large-sized intraoral defects, achieving good functional outcomes with minimal donor site morbidity. 相似文献

Thirty-one patients with large scalp and cranium defects were reconstructed with free tissue transfer and scalp flaps. Twenty-eight of the defects resulted after tumour resection, two after infection and one after an extensive burn. Thirty-one free flaps (mainly the latissimus dorsi myocutaneous and the radial forearm fasciocutaneous) and five large (> 200 cm2) scalp flaps were used. Major complications occurred in one patient who developed meningitis and finally died (3.2%), and in one patient who lost a latissimus dorsi flap (3.2%). There were no other significant problems with the remaining patients. All other free flaps and scalp flaps survived. Primary reconstruction with free tissue transfer was our first choice of treatment because of the wide spectrum of advantages of free flaps. However, in a limited number of cases there was an indication for large scalp flaps, which, when properly designed, gave satisfactory results. 相似文献

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. 相似文献

Different reconstruction techniques of the anterior and middle skull base as consequence of a defect after surgical treatment of neoplastic pathologies are described in the literature. The aim of the present study is to present our experience regarding the use of microvascular free flaps for reconstruction of the anterior or middle skull base after large defects caused by removal of malignant neoplasms. From 2000 to 2004, in the Department of Maxillo-Facial Surgery of the University of Rome "La Sapienza" and "Tor Vergata," 13 surgical procedures for reconstruction of anterior and middle skull base defects by free flaps were performed in 11 patients. Data on patient demographics, histopathology, location and size of defect, type of reconstruction, and postoperative complications were obtained from medical record charts. A safe soft tissue closure of the intracranial space was achieved in all patients. Defect repair was accomplished by revascularized transfer of rectus abdominis flaps in seven cases, latissimus dorsi muscle flaps in two patients, radial forearm flap in one case, and fibula flap in one case. There were two total flap losses; the secondary defect repair was accomplished in both cases by revascularized transfer of latissimus dorsi muscle flap. No donor site complications were observed in all the flaps. The mean operation time was 85 hours; patients were hospitalized for a mean period of 14 days. The method of choice for the reconstruction of anterior or middle skull base defect should be based upon careful evaluation of the single case and, particularly, the localization and entity of the residual defect. For defects that require large amounts of soft tissue, the latissimus dorsi free flap and the rectus abdominis free flap are the best appropriate choices for reconstructive procedures for anterior and middle skull base tumors. 相似文献

When managing extensive maxillary defects it is difficult to provide a stable biomechanical frame for prostheses, and obturators are difficult to use. This study reviews cases involving angular branch artery pedicled scapular bone flaps (SBF) combined with or without latissimus dorsi musculocutaneous flap (LDMF). Between 2004 and 2007, four wide maxillary defects were repaired using the angular vascularized branch of the scapular bone. Tumor resection with immediate reconstruction using combined LDMF and angular artery pedicled SBF was used in 3 cases and angular artery pedicled SBF alone in 1 case. Follow up was 6 months to 2 years. Satisfactory results were obtained for facial contour, appearance, speech, deglutition and breathing. No donor site complications or restricted shoulder movements were detected. The only complication was a minor infection of one flap. This procedure is useful, functionally and aesthetically, for reconstruction of wide extensive maxillary defects as bone supplied by the angular branch has a wider arc of rotation in relation to skin flaps and has a longer pedicle length from the axillary artery, long enough to reach the maxilla. This procedure also benefits from the flexibility of the soft tissue pedicle, such as the latissimus dorsi, serratus anterior and fasciocutaneous flaps. 相似文献

IntroductionSurgery of extensive skull base tumour results of a defect of soft and hard tissue and dura. Free flap reconstruction provides tissue to restore the defect and separate the intracranial content from the bacterial flora of the nasal fossae. Vertical and transverse rectus abdominis myocutaneous free flap are usually used. This study was designed to compare our experience of latissimus dorsi free flap reconstruction of extensive skull base defects after tumour resection with the literature concerning the use of other types of free flaps.Material and methodAll extensive skull base tumour resections with latissimus free flap reconstruction made in the head and neck oncology unit of the Institut Curie, Cancer Centre, between January 2004 and December 2009 were reviewed.ResultsTwo infectious complications were observed (11.7%), two cases of CSF leak (11.7%), one case of wound dehiscence following tumour resection comprising the nasal skin (5.9%) and one case of partial distal necrosis of the flap in a zone of skin resection (5.9%) were observed. No flaps were lost. Two latissimus dorsi donor site haematomas were observed (11.7%).ConclusionWhen reconstruction of extensive skull base defect need free flap, the latissimus dorsi free flap is a reliable solution. 相似文献

Microvascular free flap transfers have become a preferred reconstructive technique; however, rare complications may still prove devastating. This study reviewed 213 consecutive freetissue transfers in order to assess the incidence and causes of complications in patients undergoing microvascular free flap reconstruction in the oral and maxillofacial region. In most cases, reconstruction was undertaken after resection of a malignant tumor. The flap donor sites were the radial forearm (n=111), rectus abdominis (n=88), scapula (n=13), and latissimus dorsi (n=1). The superior thyroid artery and the external jugular vein were commonly used as recipient vessels for anastomosis. The overall flap success rate was 99%. There were 7 cases of postoperative vascular thrombosis (6 venous and 1 arterial), constituting 3.3% of the entire series. Five flaps were salvaged, representing a 71.4% successful salvage rate in cases of vascular complications. Most of the successful salvage attempts were made within 24 hours of the end of the initial operation, and the successful salvage rate for re-exploration was 100%. Finally, the total flap loss rate was 0.9% and the partial flap loss rate was 2.3%. We conclude that early re-exploration should be the first choice for management of vascular compromised flaps. Complications at the donor site occurred in 17 cases (8.0%), the most common complication of which was partial skin graft loss after harvesting a radial forearm flap (n=10; 9.0%). Recipient and donor site morbidity was limited and considered acceptable. 相似文献

In trauma patients with severe intracranial hemorrhaging, diagnosing facial bone fractures can be delayed. In frontal sinus fractures with nasofrontal duct obstruction, obliteration of the nasofrontal duct and the sinus is the current treatment of choice. But with inadequate management, ascending infections happen, and widely spread infections can involve the entire frontal soft tissues, which result in meningitis, encephalitis, and subcutaneous abscess pockets creating skin defects. In the treatment of these infections, radical debridement of all infected tissues including galea, pericranium, and surrounding soft tissues is obligatory; hence, available local vascularized flap options for obliteration of the postdebridement defect are scarce. In these situations, free-tissue transfer can be a treatment option. Although there have been numerous reports of using nonvascularized materials for obliteration of the frontal sinus, the material itself can serve as a nidus for infection, and it is generally accepted that well-vascularized tissues have greater ability to withstand local soft-tissue infection and osteomyelitis. Hence, we report 3 cases where we performed latissimus dorsi myocutaneous flaps for severe frontal sinus infections after frontal cranioplasty for severe hemorrhaging. Large bulks of muscle obliterated the nasofrontal duct and the dead space surrounding the entire frontal sinus. The latissimus dorsi myocutaneous flap is not a permanent solution for frontal sinus reconstruction, which requires a secondary bony reconstruction. However, when we face acute stages of intractable infections of the frontal sinus, it can control the infection and result in saving the patient's life. 相似文献

Head and neck surgical defects after oncological resection of advanced carcinoma involving the oral cavity are often composite and involve bone, mucosa, soft tissues and skin. For the most extensive defects, the simultaneous association of two free flaps is the best choice to improve the function of the preserved structures. This procedure is difficult and involves prolonged surgery, therefore it is only possible in selected patients. In some composite head and neck defects the association of free and locoregional flaps seems to be indicated. This study, discusses the use of free and locoregional flap association, focusing on its aesthetic advantages and functional results. From January 1995 to December 2006, 30 patients received simultaneous locoregional and free flap transfer for closure of post-ablative oral cavity defects. Microvascular tissue transfer included the radial forearm, anterolateral thigh, rectus abdominis, and fibula and iliac crest free flaps. Locoregional flaps included the cervicofacial, cervicopectoral, deltopectoral, pectoralis major, latissimus dorsi and posterior scalp flaps. Based on the good functional and aesthetic outcome and low rate of complications, the association of free and locoregional flaps represents a good reconstructive option for patients with extensive post-oncological composite head and neck defects. 相似文献

Soft tissue expansion is a mechanical process that increases the surface area of local tissue available for reconstructive procedures. In most cases, adjacent tissue that matches the recipient site in color, texture, and hair-bearing quality is preferred for tissue expansion. In this particular case with neurocutaneous syndrome, the defects that resulted from removal of parts of a giant hairy nevus overlying the latissimus dorsi muscle bilaterally were grafted with a split-thickness skin graft. Two expanders were then placed under the latissimus dorsi muscles. After full expansion of the grafted area, some part of the remaining nevus surrounding the grafted area was removed and the defects were covered with the expanded skin graft obtained after deflation of the expanders. The expanders placed under the latissimus dorsi muscle in the first operation were reused in the second operation to obtain a second expansion of the skin graft. After the second expansion of the skin graft, the expanders were deflated and another portion of the remaining nevus surrounding the grafted area was removed. The resulting defects were again covered with the excess expanded skin graft. Although repeated expansion of the skin graft is a time-consuming and laborious process, it eliminates the need for taking repeated skin grafts; it decreases skin graft donor site morbidity; it decreases possible infectious complications of tissue expansion by decreasing the number of surgical interventions to the expander pocket; and it increases the aesthetic outcome by keeping all the surgical scars around the grafted area without extending them into healthy surrounding skin. 相似文献

A mouth floor mucosal flap was developed to reconstruct medium-sized intraoral buccal defects, too large for primary closure if major functional and aesthetic impairment is to be avoided. Although free flaps, perforator flaps, or even skin grafts can be designed for buccal reconstruction, they may not provide good mucosal sensitivity, motility, volume, and texture to replace lost structures with similar tissue. Moreover, secondary morbidity can be avoided with this adjacent flap.In our study, 8 flap reconstruction procedures were performed from March 2009 to July 2011: 4 cases of leukoderma, 2 cases of buccal cancer (T1 N0 M0), and 2 cases of papillary epithelioma. The largest size amount to 5.3 × 3.8 cm (length × width), with a mean of 4.3 × 3.4 cm. Compared with free flaps (forearm arm flap for example) for buccal reconstruction, application of the mouth floor flap has its indications. First, to secure the motility of tongue and function of mouth opening, the upper bound of the defects was below the occlusion line. Generally, the width between top and bottom was less than 4 cm. Second, at least a partial buccinator muscle can be preserved after lesion resection and then facial collapse can be avoided. Third, patients had molar absence or relevant teeth had to be extracted during surgery.All patients recovered from intraoral surgeries with good objective and subjective speech and swallowing and aesthetics and without injury to the lingual nerve, the submandibular gland duct, and the sublingual gland. Results indicate that the mouth floor mucosal flap is reliable and technically easy for reconstructing medium-sized intraoral buccal defects, with good function and aesthetics with little secondary morbidity. 相似文献

Background. The necessity of nerve anastomosis in an attempt to regain cutaneous sensitivity following flap transfer has been the basis of many discussions. In our study, we investigated the degree of sensory recovery with emphasis on the different nerval qualities on the radial forearm and the latissimus dorsi flap. Collective. Sixty-two patients with 66 latissimus dorsi flaps and 19 patients with a radial forearm free flap were examined. Results. Except for five latissimus dorsi and two radial forearm flaps, all flaps investigated showed clinical signs of sensory recovery, whereby the degree and quality of cutaneous reinnervation varied. In comparison, neural reconstruction did not lead to any clinical improvement. Conclusion. Based on our clinical results, we consider nerve reconstruction during radial forearm and latissimus dorsi free flap transfer unnecessary. To what extent this can be said for other flaps requires further investigation. 相似文献
