The free latissimus dorsi skin-muscle flap has gained wide popularity to solve a variety of difficult reconstructive surgical problems. However, the donor site of this skin-muscle flap leaves a conspicuous scar and indentation, and frequently in the recipient site the skin-muscle flap leaves a conspicuous scar and indentation, and frequently in the recipient site the skin-muscle flap requires staged defatting procedures. This case demonstrates the use of the latissimus dorsi muscle flap for lower-extremity reconstruction, where a new blood supply and soft-tissue coverage are required to solve a chronically infected, open ankle joint. By taking the latissimus muscle only through a short, axillary incision, much of the donor-site deformity is minimized, and after transfer, the muscle can be molded and shaped to fit the recipient site with split-thickness skin graft coverage. This combination of free muscle flap transfer and skin graft would appear to provide a flexible, contoured, well-vascularized muscle with a relatively inconspicuous incision and skin-graft donor site. 相似文献

Based on this review of 35 cases of chronic bony wounds, it would appear that the free-muscle flap method of wound closure and nourishment after thorough dead bone debridement is an attractive and successful alternative to local skin flaps, staged skin flaps, or extend skin-muscle flaps in areas where reliable muscle flaps are not available. It would also seem that the latissimus dorsi muscle flap with skin graft is an ideal donor-muscle transfer with features allowing a favorable and contoured surface in the recipient site and minimal aesthetic and functional deformity in the donor site. 相似文献

The latissimus dorsi muscle is among the most commonly used muscle flaps because it has broad versatility and is generally believed to result in minimal donor-site morbidity. However, the normal physiology of the shoulder girdle depends on the function of this muscle. Therefore, we have undertaken this review of the literature to examine the issue of biomechanical and functional changes of the shoulder that occur with transfer of the latissimus dorsi muscle and to determine whether these changes result in deficits in normal function. A review of the literature pertaining to all aspects of the latissimus muscle and shoulder function following muscle transfer was conducted. The latissimus muscle functions in extension, adduction, and internal and external rotation. After the transfer of the muscle there are deficits in extension and adduction. These deficits result in a faster rate of fatigue during activities in which the arms are extended over the head, such as ladder climbing and swimming. In addition, there is no decrease in range of shoulder motion. 相似文献

The latissimus dorsi muscle flap is a versatile flap used in a variety of reconstructive procedures. The major complication reported with its use is donor-site seroma, reported to occur in 20 to 79 percent of cases. A retrospective review of 47 patients undergoing latissimus dorsi muscle harvest from April of 1998 through May of 2002 was performed. Progressive tension sutures were used during donor-site closure in 22 patients from March of 2000 through May of 2002. This group was compared with historical controls from April of 1998 through March of 2000 (n = 23) who underwent latissimus dorsi harvest without use of the technique. Seven of 23 controls (30 percent) developed seromas at the donor site, compared with 0 of 22 (Fisher's exact text, p = 0.0092). The authors conclude that use of progressive tension sutures placed at the time of donor-site closure is an effective method to reduce or eliminate the most common complication associated with latissimus dorsi harvest. Technique recommendations are reviewed. 相似文献

Neurovascular free-muscle transfer for the treatment of established facial paralysis following ablative surgery in the parotid region 总被引:5,自引:0,他引:5

Neurovascular free-muscle transfer for facial reanimation was performed as a secondary reconstructive procedure for 45 patients with facial paralysis resulting from ablative surgery in the parotid region. This intervention differs from neurovascular free-muscle transfer for treatment of established facial paralysis resulting from conditions such as congenital dysfunction, unresolved Bell palsy, Hunt syndrome, or intracranial morbidity, with difficulties including selection of recipient vessels and nerves, and requirements for soft-tissue augmentation. This article describes the authors' operative procedure for neurovascular free-muscle transfer after ablative surgery in the parotid region. Gracilis muscle (n = 24) or latissimus dorsi muscle (n = 21) was used for transfer. With gracilis transfer, recipient vessels comprised the superficial temporal vessels in 12 patients and the facial vessels in 12. For latissimus dorsi transfer, recipient vessels comprised the facial vessels in 16 patients and the superior thyroid artery and superior thyroid or internal jugular vein in four. Facial vessels on the contralateral side were used with interpositional graft of radial vessels in the remaining patient with latissimus dorsi transfer. Cross-face nerve grafting was performed before muscle transfer in 22 patients undergoing gracilis transfer. In the remaining two gracilis patients, the ipsilateral facial nerve stump was used as the primary recipient nerve. Dermal fat flap overlying the gracilis muscle was used for cheek augmentation in one patient. In the other 23 patients, only the gracilis muscle was used. With latissimus dorsi transfer, the ipsilateral facial nerve stump was used as the recipient nerve in three patients, and a cross-face nerve graft was selected as the recipient nerve in six. The contralateral facial nerve was selected as the recipient nerve in 12 patients, and a thoracodorsal nerve from the latissimus dorsi muscle segment was crossed through the upper lip to the primary recipient branches. A soft-tissue flap was transferred simultaneously with the latissimus muscle segment in three patients. Contraction of grafted muscle was not observed in two patients with gracilis transfer and in three patients with latissimus dorsi transfer. In one patient with gracilis transfer and one patient with latissimus dorsi transfer, acquired muscle contraction was excessive, resulting in unnatural smile animation. The recipient nerves for both of these patients were the ipsilateral facial nerve stumps, which were dissected by opening the facial nerve canal in the mastoid process. From the standpoint of operative technique, the one-stage transfer for latissimus dorsi muscle appears superior. Namely, a combined soft-tissue flap can provide sufficient augmentation for depression of the parotid region following wide resection. A long vascular stalk of thoracodorsal vessels is also useful for anastomosis, with recipient vessels available after extensive ablation and neck dissection. 相似文献

The thin latissimus dorsi perforator-based free flap for resurfacing 总被引:11,自引:0,他引:11
The authors present their experience with "thin" latissimus dorsi perforator-based free flaps for resurfacing defects. Perforator-based free flaps have been used for various kinds of reconstruction by presenting important donor structures. The thin latissimus dorsi perforatorbased free flap included only the skin and superficial adipose layer to reduce its bulkiness by dissection through the superficial fascial plane. This flap was used in 12 clinical cases, without flap necrosis or other serious postoperative complications. All of the patients were examined by preoperative power Doppler ultrasound in the spectral Doppler mode to search for the most reliable perforator. This noninvasive ultrasound technique determines the exact location and course of and ensures the reliable flow of the perforators; therefore, it greatly assists microsurgeons in saving operation time and in selecting the most suitable design for perforator flap reconstruction. We used perforators that were identified several centimeters from the lateral border of the latissimus dorsi muscle. The thin flap dimensions could be safely designed for flaps measuring up to 20 cm in length and 8 cm in width for primary closure of the donor site. Generally, a long pedicle is not required for resurfacing reconstructions, where small recipient arteries in the bed are acceptable for anastomosis with pedicles. However, pedicle dissection to the proximal vessels through the latissimus dorsi muscle was required when it was necessary to match the recipient vein for anastomosis. The authors conclude that this thin latissimus dorsi perforator-based free flap has great potential for resurfacing because of its constant thickness, easy elevation with the help of power Doppler ultrasound information, and proper flap size for moderate defects caused by scar contracture release, superficial tumor ablation, and so on. 相似文献

Donor site sequelae after autologous breast reconstruction with an extended latissimus dorsi flap 总被引:5,自引:0,他引:5

The indications for autologous reconstruction are increasing. The standard procedure is the transverse rectus abdominis muscle flap; however, this flap has contraindications and drawbacks. The latissimus dorsi muscle flap is simple and reliable. Hokin et al. demonstrated in 1983 that this flap can be extended and used for breast reconstruction without an implant. Since then, it has been widely studied in this setting and is known to provide good aesthetic results. Dorsal sequelae, conversely, were not appraised. The aim of this study was to assess objective and subjective dorsal sequelae after the harvest of an extended flap. Forty-three consecutive patients who had had breast reconstruction with an autologous latissimus dorsi flap were assessed by a surgeon and a physiotherapist for muscular strength and shoulder mobility. Patient opinion was studied through a questionnaire. Mean delay between the operation and the evaluation was 19 months. Early complications, mainly dorsal seromas, were frequent after the harvest of an extended flap (72 percent). There was no late morbidity and, especially, no flap loss or partial necrosis. As for functional results, 37 percent of the patients had complete adjustment and 70 to 87 percent demonstrated no change in shoulder strength. Sixty percent of the patients experienced no limitation in everyday life, and 90 percent said they would undergo this procedure again. The authors show that dorsal sequelae after an extended latissimus dorsi flap are minimal and that this technique compares favorably with the transverse rectus abdominis muscle flap. 相似文献

The chest-wall deformity associated with Poland's syndrome was reconstructed in eight male patients 16 to 38 years old (average age 20 years). Follow-up ranged from 1 to 10 years. Two patients had custom silicone implants placed subcutaneously. In one of these patients, the edge of the implant could be seen. Three patients had transfer of an ipsilateral pedicled latissimus dorsi muscle flap with intact thoracodorsal nerve. All these patients had noticeable atrophy of the flap, and one underwent subsequent implantation of a custom silicone implant beneath the flap. Three other patients had a custom silicone implant covered immediately by a latissimus dorsi muscle flap. All four patients who had a combination of silicone implant and latissimus dorsi muscle flap had satisfactory correction of their deformity. 相似文献

Sixty latissimus dorsi flaps. 总被引:10,自引:0,他引:10
In clinical experiences with 60 cases, we have found the latissimus dorsi to be a reliable and versatile flap. We describe its use for a functional muscle transfer (in restoration of elbow flexion and repair of abdominal wall defects), for arm and shoulder coverage, for breast reconstruction, and as a free flap. 相似文献

Five patients with insufficient soft-tissue coverage on below-knee amputation stumps have been treated with free-tissue transfer surgery to preserve a functional below-knee prosthetic level. The flaps employed include one latissimus dorsi myocutaneous flap, two latissimus dorsi muscle-skin graft flaps, one groin flap, and one foot-fillet flap. All five flaps survived; one patient required early venous anastomosis reexploration and revision. The patients have been followed for a mean duration of 5.5 years (range 3 to 8 years). The mean duration to first ambulation with a prosthesis was 3.6 months (range 2 to 7 months). Four of the five patients developed ulcerations on or adjacent to their flaps which required surgical revision. The patients required a mean of 1.28 prosthesis changes annually since surgery. The functional motion (mean active knee motion is 100 degrees) and ligamentous stability of the knee joints were well preserved in all patients. Five patients wear patella tendon-bearing prostheses, with one requiring an additional thigh corset. In two of the patients, nerve anastomoses to their flaps were performed. Both patients developed true cutaneous sensibility, but nevertheless experienced flap ulceration. All the patients are fully ambulatory on their free flaps. Free-tissue transfer can assist in preserving traumatic below-knee amputations so that patients can benefit from the functional advantage of a below-knee prosthetic device. 相似文献

Two types of perforators, septocutaneous and musculocutaneous, are found in the same donor site of the flank area, and two perforator flaps based on each perforator are clinically available. Therefore, it is necessary to distinguish them from one another using different nomenclatures. Accordingly, the perforator flap based on a musculocutaneous perforator is named according to the name of the muscle perforated, the latissimus dorsi perforator flap, and the perforator flap based on a septocutaneous perforator, located between the serratus anterior and latissimus dorsi muscles, is named according to the name of the proximal vessel, the thoracodorsal perforator flap. In this series of 42 latissimus dorsi perforator flaps, flap size ranged from 5 x 3 cm to 20 x 15 cm, and two complications were observed: a marginal necrosis in an extremely large flap (26 x 12 cm) and a failure caused by infection. The thoracodorsal perforator flap was used in 14 cases, including two cases of chimeric composition. Flap size ranged from 4.5 x 3.5 to 18 x 15 cm, with no complications. In the two patterns of perforator flap that the author used, initial temporary flap congestion was observed in five latissimus dorsi perforator flap cases and two thoracodorsal perforator flap cases, when the flap was designed as a large flap or a less reliable perforator was selected. However, the congestion was not serious enough to cause flap necrosis. Several techniques, such as T anastomosis or inclusion of an additional perforator or a small portion of muscle, are recommended to prevent the initial flap congestion, especially when an unreliable perforator is inevitably used or when a flap larger than 20 cm long is required. A small portion of the muscle was included in six cases, when an unduly large or improperly long flap was planned. All of the flaps were successful and ranged from 22 x 7 to 15 x 28 cm, except for one case of distal flap necrosis in an extraordinarily large flap measuring 34 x 10 cm. Diverse selection of the perforator flap is one of the great advantages of the flank donor site, providing it with wider availability and more versatile composition for reconstruction or resurfacing. 相似文献

Neurovascular free-muscle transfer to treat facial paralysis associated with hemifacial microsomia 总被引:2,自引:0,他引:2
Despite the wide spectrum of hemifacial microsomia manifestations, treatment mainly focuses on mandible and ear abnormalities, rather than on facial paralysis. In fact, the surgical treatment of facial paralysis associated with hemifacial microsomia is quite underdeveloped, because the degree of paralysis is frequently incomplete or partial. Timing and type of surgery are also difficult to determine. Neurovascular free-muscle transfer is now a standard procedure for the dynamic smile reconstruction of longstanding facial paralysis. This type of strategy has considerable potential in the treatment of facial paralysis in patients with hemifacial microsomia. We present here our experience with neurovascular free-muscle transfer for smile reconstruction in eight patients with facial paralysis associated with hemifacial microsomia. The age of the patients at the time of surgery ranged from 7 to 28 years old, (average, 13.9 years). Six were male patients and two were female patients. The two-stage method combining gracilis muscle transfer with cross-face nerve grafting was performed in three patients, whereas the one-stage transfer of the latissimus dorsi muscle was performed in five. To construct a natural or near-natural smile, the muscles were transferred into the paralyzed cheek in all except one patient, in whom the latissimus dorsi muscle was transferred into the sublabial area to reconstruct a paralyzed lower lip. A dermal flap segment vascularized with perforating vessels from the latissimus dorsi muscle was simultaneously inserted into the underdeveloped cheek for soft-tissue augmentation in this patient. Muscle contraction was evident in all patients between 4 and 8 months after muscle transfer. Our present series revealed that neurovascular free-muscle transfer is a good option not only for smile reconstruction but also for restoration of the facial contours of patients with hemifacial microsomia. Compared with the two-stage method combining gracilis muscle transfer with cross-face nerve grafting, the one-stage method using the latissimus dorsi muscle has some advantages, including a one-stage operation, a shorter recovery period, and the absence of sequelae that occur after harvesting a sural nerve. 相似文献

Autologous breast reconstruction with the extended latissimus dorsi flap 总被引:10,自引:0,他引:10

The extended latissimus dorsi myocutaneous flap can provide autogenous tissue replacement of breast volume without an implant. Nevertheless, experience with the extended latissimus dorsi flap for breast reconstruction is relatively limited. In this study, the authors evaluated their experience with the extended latissimus dorsi flap for breast reconstruction to better understand its indications, limitations, complications, and clinical outcomes. All patients who underwent breast reconstruction with extended latissimus dorsi flaps at the authors' institution between January of 1990 and December of 2000 were reviewed. During the study period, 75 extended latissimus dorsi flap breast reconstructions were performed in 67 patients. Bilateral breast reconstructions were performed in eight patients, and 59 patients underwent unilateral breast reconstruction. There were 45 immediate and 30 delayed reconstructions. Mean patient age was 51.5 years. Mean body mass index was 31.8 kg/m2. Flap complications developed in 21 of 75 flaps (28.0 percent), and donor-site complications developed in 29 of 75 donor sites (38.7 percent). Mastectomy skin flap necrosis (17.3 percent) and donor-site seroma (25.3 percent) were found to be the most common complications. There were no flap losses. Patients aged 65 years or older had higher odds of developing flap complications compared with those 45 years or younger (p = 0.03). Patients with size D reconstructed breasts had significantly higher odds of flap complications compared with those with size A or B reconstructed breasts (p = 0.05). Obesity (body mass index greater than or equal to 30 kg/m2) was associated with a 2.15-fold increase in the odds of developing donor-site complications compared with patients with a body mass index less than 30 kg/m2 (p = 0.01). No other studied factors had a significant relationship with flap or donor-site complications. In most patients, the extended latissimus dorsi flap alone, without an implant, can provide good to excellent autologous reconstruction of small to medium sized breasts. In selected patients, larger breasts may be reconstructed with the extended latissimus dorsi flap alone. This flap's main disadvantage is donor-site morbidity with prolonged drainage and risk of seroma. Patients who are obese are at higher risk of developing these donor-site complications. In conclusion, the extended latissimus dorsi flap is a reliable method for total autologous breast reconstruction in most patients and should be considered more often as a primary choice for breast reconstruction. 相似文献

Experiments were performed on 20 New Zealand White male rabbits. Our hypotheses were that (1) latissimus dorsi (LTD) muscles transplanted into the site of a bipennate rectus femoris (RFM) muscle with neurovascular repair would retain their parallel-fibered structure and (2) the parallel-fibered structure of latissimus dorsi grafts would reduce their total fiber cross-sectional area and adversely affect force development relative to that of bipennate rectus femoris grafts and muscles. Compared with their respective donor muscles, 120 to 150 days after grafting, latissimus dorsi and rectus femoris grafts showed no change in the number of fibers and a decrease in the mean single-fiber cross-sectional area to approximately 70 percent. The latissimus dorsi grafts, which remained parallel-fibered, developed maximum forces 34 and 23 percent of the values for fully activated rectus femoris grafts and muscles, respectively. The deficit in the maximum force of the latissimus dorsi grafts resulted primarily from the smaller total-fiber cross-sectional area as a result of the parallel-fibered structure. 相似文献

We report free serratus transplantation in 100 consecutive patients, 10 in combination with the latissimus muscle and 2 with rib. Transplantation was performed for extremity soft-tissue coverage, contour correction, and facial reanimation. Twenty-two patients received serratus transplantation as part of complex reconstruction requiring multiple microvascular transplants. Overall success was 99 percent, with a single flap failure. Four patients suffered partial flap loss. Emergent reexploration for suspected vascular occlusion was infrequent, required in six flaps (6.0 percent), with an 83 percent salvage rate. Significant complications occurred in 18 percent of recipient sites and 12 percent of donor sites, with eight patients developing seroma/hematoma. No scapular winging was noted, and all patients retained full shoulder range of motion. The serratus muscle flap is a highly reliable flap characterized by a consistently long pedicle, excellent malleability, and multipennate anatomy permitting coverage of complex three-dimensional wounds and consistent performance as a functional transplant. Underlying rib can be included as a myo-osseous flap to expand the versatility of this flap. 相似文献

The question as to whether anastomosis of sensory nerves is recommended for free transplants of the myocutaneous latissimus dorsi flap, reanastomosed by microvascular surgery, remains a controversial issue. In this study, a microsurgical nerve anastomosis was performed to sensitize a latissimus dorsi transplant. To determine sensation in the transplanted tissue, six patients were examined clinically. All patients had free transplants of latissimus dorsi flaps reanastomosed by microvascular surgery after tumor resection in the oral cavity. An anastomosis of the sensible auricular magnus nerve with the motor thoracodorsalis nerve was performed. Resulting sensation was determined clinically by testing for pain, temperature, pressure, two-point discrimination, and vibration. All patients showed sensation in the latissimus dorsi flap beginning between the third and the fifth month postoperatively. Therefore, resensitization of a large and voluminous myocutaneous latissimus dorsi flap should be attempted by a nerve anastomosis in this transplant. 相似文献

Does transecting the tendinous insertion of the latissimus dorsi on the humerus improve aesthetic results and avoid the displeasing bulge in the armpit that sometimes occurs when the latissimus dorsi is used for breast reconstruction? In a prospective study, 60 patients who were having breast cancer surgery and simultaneous breast reconstruction using the latissimus dorsi flap were randomized for cutting (n = 29) or leaving intact (n = 31) the tendinous muscle insertion on the humerus. The cosmetic outcome was evaluated by patients and surgeons 6 to 12 months postoperatively. Patients reported good cosmetic results in 29 of 31 cases with the humeral insertion left intact and in 26 of 29 cases when the tendon was cut (p = 0.59), as compared with 21 of 31 cases versus 25 of 29 cases (p = 0.091), according to the surgeon's evaluation. A lateral bulge was more frequently observed by the surgeons in the group with intact insertion (10 of 31 patients), as compared with the group with a transected humeral insertion (2 of 29 patients). Discomfort caused by this bulge was reported by 19 of 31 patients with intact insertion, but only 3 of 29 patients with the tendon cut (p < 0.0001). The additional transection of the tendon was not associated with any complications. The additional transection of the tendinous humeral insertion of the latissimus dorsi muscle improves aesthetic results and avoids a displeasing bulge in the axilla when the latissimus dorsi flap is used for breast reconstruction. 相似文献
