Salvage Operation of Head and Neck Reconstruction Using a Pedicled Latissimus Dorsi Myocutaneous Flap with Distally Positioned Skin Paddle

Background: There are many situations in head and neck reconstruction where a pedicled flap must be chosen over free flaps. In such situations, one of our options is a pedicled latissimus dorsi (LD) myocutaneous flap with distally positioned skin paddle with a more distal skin flap design. Methods: We performed 22 reconstruction cases using a distally positioned pedicled LD myocutaneous flap. When designing the skin paddle more distally than usual, it is important to include the lateral cutaneous branch of the 10th posterior intercostal artery. By splitting the skin paddle sections, the LD flap is flexible for use in complex head and neck defects. It can also be used for mandibular reconstruction by harvesting the flap with costal bone. Results: In all cases, the skin flaps survived, with a salvage rate of 100%. Conclusions: Because elevation of this flap is relatively easy, safe, and quick, this flap selection is considered practical in salvage cases after flap necrosis, and in cases after multiple procedures.

Optimizing the Pedicled Latissimus Dorsi Myocutaneous Flap in Breast Reconstruction: Lessons Learned from 110 Consecutive Flaps

Background: The pedicled latissimus dorsi myocutaneous flap (LDMCF) in autologous breast reconstruction has been superseded by abdominal free tissue transfer. Common complaints of the LDMCF include the asymmetric back scar, need for prosthesis, and high seroma rates. We believe that the LDMCF remains versatile, with distinct advantages over other autologous options: the flap can be harvested unilaterally or bilaterally, not ‘burning any bridges’ for future reconstruction in unilateral breast reconstruction; the recovery is relatively easy, without complications such as risk of long-term abdominal wall weakness; and the aesthetic results are comparable, if not superior, leading to a more “youthful” result. Methods: We performed a retrospective review over an 8-year period. Results: A total of 106 patients underwent 110 breast reconstructions. Complications included four of 106 patients (3.8%) with seroma, three of 78 (3.8%) with periprosthetic implant infection, and one case of partial flap loss. Conclusions: We learned the following: (1) Direct-to-implant can be performed in most LDMCF patients, avoiding the use of tissue expanders; (2) High BMI patients may not require an implant; (3) Back donor site aesthetics can be improved using a “bra-line-back-lift” approach; (4) Use of liposomal bupivacaine intercostal blocks and modified enhanced recovery after surgery protocol can reduce length-of-stay to overnight; (5) We achieved low seroma rates using topical fibrin glue and closed suction drains; (6) Low and high BMI patients who may not qualify for free tissue transfer are usually still surgical candidates with LDMCF; and (7) Short and long-term recovery are faster than free tissue transfer, with minimal long-term deficit.

Preliminary application of foldable pedicled latissimus dorsi myocutaneous flap for repairing soft tissue defects in shoulder and back

To explore the feasibility and effectiveness of a foldable pedicled latissimus dorsi myocutaneous flap to repair soft tissue defects in the shoulder and back. Between August 2018 and January 2023, the foldable pedicled latissimus dorsi myocutaneous flaps were used to repair soft tissue defects in the shoulder and back of 8 patients. There were 5 males and 3 females with the age ranged from 21 to 56 years (mean, 35.4 years). Wounds were located in the shoulder in 2 cases and in the shoulder and back in 6 cases. The causes of injury were chronic infection of skin and bone exposure in 2 cases, secondary wound after extensive resection of skin and soft tissue tumor in 4 cases, and wound formation caused by traffic accident in 2 cases. Skin defect areas ranged from 14 cm×13 cm to 20 cm×16 cm. The disease duration ranged from 12 days to 1 year (median, 6.6 months). A pedicled latissimus dorsi myocutaneous flap was designed and harvested. The flap was divided into A/B flap and then were folded to repair the wound, with the donor area of the flap being pulled and sutured in one stage. All 7 flaps survived, with primary wound healing. One patient suffered from distal flap necrosis and delayed healing was achieved after dressing change. The incisions of all donor sites healed by first intention. All patients were followed up 6 months to 4 years (mean, 24.7 months). The skin flap has a good appearance with no swelling in the pedicle. At last follow-up, 6 patients had no significant difference in bilateral shoulder joint motion, and 2 patients had a slight decrease in abduction range of motion compared with the healthy side. The patients' daily life were not affected, and linear scar was left in the donor site. The foldable pedicled latissimus dorsi myocutaneous flap is an ideal method to repair the soft tissue defect of shoulder and back with simple operation, less damage to the donor site, and quick recovery after operation.

Case Report of Complex Chest Wall Repair for Sternal Dehiscence After Bilateral Lung Transplantation

We report a case of a complex chest wall reconstruction because of sternal dehiscence, requiring different surgical procedures for its complete resolution. A 54-year-old man patient with Langerhans cell histiocytosis and chronic obstructive pulmonary disease underwent bilateral sequential lung transplantation through a clamshell incision, using nitinol thermo-reactive clips for sternal closure. One year later, he consulted because of chest pain, fever, and purulent secretions. Physical examination and chest X-ray revealed a right pulmonary hernia due to post-clamshell wound dehiscence. Chest wall repair was performed, placing an expanded-polytetrafluoroethylene synthetic mesh, and the sternum was realigned and fixated with titanium plates and screws. However, in the immediate postoperative period, there was a large amount of serous drainage through the surgical wound, needing negative pressure therapy. Unfortunately, the wound became necrotic with exposure to the osteosynthesis material. In addition, a chest computed tomography scan showed fluid accumulation in the anterior chest wall. Therefore, two-stage revision surgery was indicated: first, the removal of the previous prosthesis and, the definite one, the use of a pedicled latissimus dorsi myocutaneous flap to provide effective coverage of the wound. Sternal dehiscence is not an uncommon complication after clamshell incision in patients undergoing bilateral sequential lung transplantation, and it is associated with significant morbidity. In the presence of chest wall instability, surgical repair is mandatory.

Latissimus Dorsi Myocutaneous Flap Reconstruction Post Resection of a Giant Malignant Phyllodes Tumor of the Breast: A Case Report

Phyllodes tumors (PTs) are a rare group of mammary fibroepithelial lesions accounting for up to 1% of breast tumors. They display biologic diversity, ranging from benign to malignant. PTs of the breast are mostly found in females aged 35–55 years and are rare in adolescents and the elderly. They usually present as a fast growing, painless breast mass. The treatment of choice for PTs is complete excision with clear margins. In patients with large PTs, breast reconstruction results in better outcome and increased satisfaction.Our patient, a 39-year-old female presented with an enlarging breast mass over a period of 6 months. Physical examination showed a large, ulcerated mass involving the entire right breast. Histopathology revealed features of a malignant PT. Total mastectomy and immediate reconstruction with a pedicled latissimus dorsi myocutaneous flap and symmetrization reduction mastopexy of the left breast was done. At 6 months, the patient has not shown any gross tumor recurrence with acceptable cosmesis.

Autologous myocutaneous flap implantation for chronic refractory chest wall sinus with infection: a case report

BackgroundChest wall sinus with infection is a refractory disease caused by a variety of susceptible factors, and the treatment is still challenging. For clinically complex cases, although there are various surgical methods to choose from, it is still very difficult to achieve clinical cure, especially for patients with older age and many underlying diseases. Complete resection of chest wall sinus and application of repair and reconstruction technology may bring hope to refractory cases.Case presentationHerein, we report a case of a 67 year-old woman who had undergone breast cancer surgery and a history of multiple cycles of radiotherapy and chemotherapy. One year ago, she had a fistula in the left chest wall with yellow purulent fluid. After admission to our hospital, chest computed tomography (CT) showed the formation of the left chest wall sinus, accompanied by high-density images of the left clavicle, part of the ribs and part of the sternu. According to the patient's symptoms, signs and imaging examination, we preliminarily diagnosed the patient as chest wall sinus with infection and chronic osteomyelitis. Therefore, in the first-stage operation, the patient underwent left chest wall sinus resection, left partial rib resection, left partial clavicular resection and left partial sternal resection, After surgery, the wound surface was changed with gauze dressing with sensitive antibiotic solution every day until the wound surface was clean and new granulation was formed. In the second-stage operation, the wound surface was appropriately expanded, and the pedicled latissimus dorsi myocutaneous flap was transferred to the chest wall defect. Finally, the skin paddle was sutured without tension to the normal skin around the chest, and two drainage tubes were placed. Anti-infection, anti-spasm, anti-coagulation and other treatments were given after operation, and the survival of myocutaneous flap, wound healing and sinus disappearance were observed.ConclusionThe application of pedicled latissimus dorsi myocutaneous flap in the treatment of intractable chronic chest wall sinus is an effective method. It does not change the shape of the thorax. The clinical effect is satisfactory in the near and medium term, which is worthy of clinical promotion.

Application of Three Different Types of Pedicled Latissimus Dorsi Flaps in Repairing Nearby Deep Soft Tissue Defects: Cosmetic Result and Shoulder Functionality Evaluation in One Center.

The latissimus dorsi (LD) flap has generally been considered a workhorse flap in clinics. However, the impairment of shoulder function and the dramatic appearance in the donor site are the major problems associated with traditional latissimus dorsi myocutaneous flap (LDMF). Here, we analyzed the reliability of three types of LD flaps in repairing deep soft tissue defects in the upper limbs, shoulder, back, and chest wall. From December 2016 to December 2020, 21 patients from our center underwent reconstruction of deep soft tissue defects using different types of LD flaps. The distribution of the thoracodorsal artery and the location of its branches were confirmed by imaging examination. Based on the defects, traditional LDMF, thoracodorsal artery perforator flap with capillary perforators (TAPcp), or low-skin-paddle pedicled LDMF was selected and specifically designed for each patient. The appearance satisfaction and shoulder functional of daily life recovery were evaluated. A total of 12 traditional LDMF, 4 TAPcp, and 5 low-skin-paddle pedicled LDMFs were used. All flaps survived well. The donor site was sutured directly with satisfactory appearance (n = 7) or repaired using skin grafts (n = 14). Compared to traditional LDMF, TAPcp and low-skin-paddle pedicled LDMF have faster shoulder function of daily life recovery. Based on the characteristics of defects, personalized design of different types of LD flaps is a reliable option to repair different defects.

Reconstruction of Upper Extremity Using Pedicled Latissimus Dorsi Myocutaneous Island Flap and Skin Graft after Necrotizing Fasciitis: A Case Report

Necrotizing fasciitis of the upper extremities is a severe, life-threatening condition, potentially resulting in amputation or death in the absence of prompt and aggressive surgical treatment. Reconstruction is eventually required after adequate surgical debridement, and patients are often referred to a plastic surgeon for this purpose. Herein, we present the case of a patient with extensive soft tissue defects on the upper extremity after fasciotomy for necrotizing fasciitis. We successfully performed a pedicled latissimus dorsi myocutaneous island flap, full-thickness skin graft, and split-thickness skin graft for this patient. After 2 months, the patient did not have any wound problems and could carry out adequate upper extremity motion.

Free anterolateral thigh myocutaneous flap combined with pedicled latissimus dorsi myocutaneous flap transfer for functional reconstruction after resection of huge shoulder tumor

Objective: To investigate the method and effect of free anterolateral thigh myocutaneous flap combined with pedicled latissimus dorsi myocutaneous flap transfer for functional reconstruction after resection of huge shoulder tumor. Methods: The clinical data of 6 patients who were treated with pedicled latissimus dorsi myocutaneous flap combined with free anterolateral thigh myocutaneous flap to repair large-area complex defects after shoulder tumor resection at Department of Oncology Plastic Surgery, Hunan Province Cancer Hospital from December 2015 to December 2020 were retrospectively analyzed. There were 2 males and 4 females, with an average age of 41.7 years (range:29 to 56 years). There were 2 cases of synovial sarcoma,2 cases of phylloid cell sarcoma,1 case of liposarcoma and 1 case of fibrosarcoma. Before this operation, tumor resection had been performed for 1 to 5 times on each case,and the course of disease was 6 to 24 months. Pedicled latissimus dorsi myocutaneous flap combined with free anterolateral thigh myocutaneous flap were used to repair soft tissue defects and reconstruct deltoid function. Postoperative flap status, complications, appearance and function of upper limbs and tumor recurrence were recorded. Results: Six patients were followed up for an average of 21.6 months (range: 12 to 36 months). There were no serious complications after operation,and all flaps survived. No tumor recurrence was found. The appearance of shoulder contour reconstructed by flaps was satisfactory. The reinnervation effect of lateral femoral muscle was confirmed recovered smoothly by neuroelectromyography 3 months after operation. Shoulder function was mildly limited in 3 patients,moderately limited in 2 patients and severely limited in 1 patient. All patients reported significant improvement in shoulder discomfort.The overall functional results of all patients were satisfactory. Conclusion: Combined myocutaneous flaps transplantation can perfectly repair the wound left after the resection of huge shoulder tumor,minimize the recurrence of tumor,reconstruct the function of shoulder joint and greatly improve the quality of life of patients.

Open pneumothorax with extensive thoracic defects sustained in a fall: a case report

BackgroundOpen pneumothorax with chest wall deficit is a rare chest trauma that is serious and can lead to severe respiratory failure; however, it is a potentially lifesaving injury if utilized appropriately.Case presentationHerein, we report a case of an open pneumothorax with extensive chest wall deficit due to falling from a height and highlight the importance of appropriate evaluation and intervention. The patient was a Japanese man in his 50 s who fell from the 6th floor to the 3rd floor while working at a height. The left chest wall was punctured due to injury, the thoracic cavity was open as if a left anterolateral thoracotomy had been performed, and the left lung had prolapsed from the thoracic cavity to the outside. In our emergency department, tracheal intubation with a double lumen tube for differential positive pressure ventilation and a right thoracic drain were inserted, and an emergency operation was started immediately. A pulmonary suture for lung injury and closure of the left thorax were performed during the surgery. The defect was closed with the remaining tissue, but the anterior thoracic skin with poor blood flow was necrotic, so debridement was undertaken. After his general condition was improved, pedicled latissimus dorsi myocutaneous flap was implanted. He was discharged home on the 63rd hospital day.ConclusionsAlthough open pneumothorax is rare and sometimes presents lurid findings, we highlighted that it is important to quickly assess the life-threatening organ injury, perform positive pressure ventilation by tracheal intubation, thoracic drainage, and wound closure simultaneously respond calmly as a team.

RECURRENT DERMATOFIBROSARCOMA PROTUBERANS OF THE CLAVICULAR REGION: RADICAL EXCISION AND RECONSTRUCTION WITH LATISSIMUS DORSI MYOCUTANEOUS FLAP

Dermatofibrosarcoma protuberans (DFSP) is a soft tissue tumor with high propensity for local recurrence. We present a case of a 53-year-old woman with a recurrent DFSP of the clavicular region. The patient underwent extensive local excision including the external cortical bone of the left clavicle. The resulting large defect was reconstructed using pedicled Latissimus Dorsi myocutaneous flap. The histopathological examination confirmed dermatofibrosarcoma protuberans with clear surgical margins and the patient was satisfied with the final aesthetic result.

Treatment of chronic bronchopleural fistula and recurrent empyema using a latissimus dorsi myocutaneous flap: a case report and literature review

Bronchopleural fistula is a severe complication with a high mortality rate that occurs after pulmonary resection. Several treatment options have been suggested; however, it is a challenge to treat this condition without recurrence or other complications. In this case report, we describe the successful performance of a pedicled latissimus dorsi myocutaneous flap transfer, with no recurrence or donor site morbidity.

Staged repair strategy for chronic sacrococcygeal radiation ulcer

Objective: To investigate the clinical effect of staged repair strategy for chronic sacrococcygeal radiation ulcer. Methods: The retrospective cohort study method was applied. Twelve patients with chronic sacrococcygeal radiation ulcer were admitted to Beijing Jishuitan Hospital from January 2010 to June 2020, including 7 males and 5 females, aged 38-74 years. The thorough debridement was performed in the first stage, with wounds area after debridement ranging from 8 cm×6 cm to 22 cm×14 cm, and continuous vacuum sealing drainage (VSD) was performed after the debridement operation. In the second stage, personalized surgery scheme was formulated according to the patient's age, systemic condition, vascular condition, and the position, size, and depth of wound. Six cases were reconstructed with superior/inferior gluteal artery perforator flaps, 4 cases were repaired with gluteus maximus myocutaneous flaps, 1 case was repaired with pedicled latissimus dorsi myocutaneous flap, and 1 case was reconstructed with free transplantation of latissimus dorsi myocutaneous flap. The area of flaps or myocutaneous flaps ranged from 10 cm×8 cm to 25 cm×18 cm. Donor sites of the flaps were sutured primarily in 9 patients and in the other 3 patients were repaired with intermediate split-thickness skin graft in back. The survival of flap or myocutaneous flap after operation, recurrence of tumor, and the appearance and texture of flap or myocutaneous flap, and wound healing were observed during follow-up. Results: Flaps or myocutaneous flaps in 11 patients survived after operation, and superior gluteal artery perforator flap in 1 patient had partial distal necrosis, which was covered again with flap pushed to the distal after debridement and resection of the necrotic tissue. The wounds in 8 patients achieved primary healing, 1 patient repaired with superior gluteal artery perforator flap experienced subcutaneous infection, 1 patient repaired with superior gluteal artery perforator flap suffered distal venous congestion of the flap, and 1 patient repaired with gluteus maximus myocutaneous flap had hematoma under myocutaneous flap, and 1 patient repaired with retrograde latissimus dorsi myocutaneous flap had incision exudation and dehiscence, which were all healed after dressing change, etc. There was no recurrence of tumor after the operation. The wounds healed well during follow-up of 2-52 months after discharge, with no recurrence of infection, and the flaps were soft in texture, with satisfactory appearance and well healed donor sites. Conclusions: On the basis of thorough debridement and VSD in the first stage, superior/inferior gluteal artery perforator flap, gluteus maximus myocutaneous flap, or pedicled/free latissimus dorsi myocutaneous flap with abundant blood supply is applied to repair chronic sacrococcygeal radiation ulcer in the second stage. The staged operation is reliable, with minimal injury to the donor site of flap and satisfactory therapeutic effect.

“Wing-Shaped Skin Component of Latissimus Dorsi Myocutaneous Flap Design for Breast Reconstruction—Useful Innovation”

We describe a pedicled latissimus dorsi myocutaneous (LDMC) flap with a wing-shaped skin paddle to cover large breast defects. It allows primary closure of the donor site with the added advantage of some flap projection. This is performed utilising the principles of M-plasty and the anatomy of thoracodorsal musculocutaneous perforators, which would not be possible with the conventional flap design. Analysis of a series of 23 patients who underwent breast reconstruction using wing shaped skin component LDMC technique between 2011 and 2019 in a breast unit of a Tertiary Care Hospital is presented here. Patient characteristics, technical details, and outcomes were analysed. Mean patient age was 41 (SD 10.9) years. The mean defect dimensions were 13.5 (SD 3.4) cm and 10.5 (SD 2.6) cm in length and width, respectively. The mean flap area was 147 (SD 67.2 cm2).The donor site defect was closed primarily in all the cases. The average length of inhospital stay was 4.9 (SD 1.5) days (range 3–9 days). One patient (4.3%) had marginal necrosis of the flap, three patients (13%) had donor site seroma, and two patients (8.7%) suffered donor site wound dehiscence. None of the complications entailed re-surgery or delay the onset of adjuvant therapy. At a mean follow-up of 37.5 (SD 33.9) months, none of the patients reported tumour recurrence or donor site morbidity. Wing-shaped skin component of latissimus dorsi myocutaneous flap offers a simple and reliable pedicled flap to cover large breast defects with minimal donor site morbidity. It creates a mild breast mound and may avoid the use of implants and its associated complications in small-breasted patients. It can be conveniently performed in non-microsurgical setups.

Validation of an in vivo porcine simulation model of pedicled latissimus dorsi myocutaneous flap elevation

BackgroundIn vivo and ex vivo simulation training workshops can contribute to surgical skill acquisition but require validation before becoming incorporated within curricula. Ideally, that validation should include the following: face, content, construct, concurrent, and predictive validity.MethodsDuring two in vivo porcine surgical training workshops, 27 participants completed questionnaires relating to face and content validity of porcine in vivo flap elevation. Six participants’ performances raising a pedicled myocutaneous latissimus dorsi (LD) flap in the pig (2 experts and 4 trainees) were sequentially and objectively assessed for construct validity with hand motion analysis (HMA), a performance checklist, a blinded randomized procedure-specific rating scale of standardized video recordings, and flap viability by fluorescence imaging.ResultsFace and content validity were demonstrated straightforwardly. Construct validity was demonstrated for average procedure time by HMA between trainees and experts (p = 0.036). Skill acquisition was demonstrated by trainees’ HMA average number of hand movements (p = 0.046) and fluorescence flap viability (p = 0.034).ConclusionFace and content validity for in vivo porcine flap elevation simulation training were established. Construct validity was established for an in vivo porcine latissimus dorsi flap elevation simulation specifically. Predictive validity will prove more challenging to establish.Level of evidence: Not ratable .

Versatility of the Pedicled Latissimus Dorsi Myocutaneous Flap in Reconstruction of Upper Limb and Trunk Soft Tissue Defects

Purpose The purpose of the study was to share our indications, technique, outcome, and complications associated with the pedicled latissimus dorsi myocutaneous flap (LDMF) for reconstructing various upper limb and trunk soft tissue defects.Patients and Methods We reviewed the prospectively collected data of the patients who underwent reconstruction of upper limb/trunk soft tissue defects with pedicled LDMF between January 2016 and March 2019. By analyzing the clinical scenarios, the location of flap inset, the arc of rotation, reach of the flap, and associated complications, we put forward few significant findings from our experience.Results Thirty-four patients were included in the study: 13 of them underwent LDMF for coverage of upper limb defects, 12 of them for postradical mastectomy soft tissue defects, 8 for posterior trunk reconstruction, and 1 for sternal wound infection. LDMF was successfully used to cover the scapula, anterior and posterior arms, axilla, cubital fossa, mid-forearm, breast, sternum, and midline dorsal wounds. When used reversely, the flap could cover the exposed spine in the midline dorsum. Three patients (9%) had major complications (two patients had partial flap necrosis which required additional debridement and skin grafting, and one patient required an additional transpositional flap). Three patients had minor complications (managed nonoperatively).Conclusion Pedicled LDMF is a straightforward and versatile option for reconstruction of the varied upper limb and trunk soft tissue defects with minimal complications.Level of Evidence This is a level IV, therapeutic, retrospective study.

Latissimus Dorsi Myocutaneous Flap in Immediate Reconstruction after Salvage Mastectomy Post-Lumpectomy and Radiation Therapy.

Background:Breast reconstruction after salvage mastectomy (SM) for recurrent cancer represents a challenge in preradiated patients due to the increased complication rate. Latissimus dorsi myocutaneous flap (LDMF) represents a good reconstructive option due to its versatility, safety, and adaptability.Methods:Fifty-nine patients treated in the Breast Surgery Unit at the University Hospital of Parma (Italy) between January 2010 and December 2017 for ipsilateral breast recurrent cancer, previously treated by partial mastectomy plus whole-breast radiation therapy, were analyzed. They underwent SM and immediate reconstruction with implant-assisted pedicled LDMF. We registered local treatment, oncologic characteristics, complications, capsular contracture rate, DASH test, and BREAST-Q scores.Results:Mean implant volume was 403 g (range 135–650 g). Contralateral operations were 16/59 (27.1%). We obtained complete postoperative pain control in most cases with paracetamol. Medium hospital stay was 2.8 days. We registered 3.4% major complications and 6.8% minor ones. Mean follow-up was 26.65 months (range 3–91.9 months). DASH questionnaire evidenced no disability for 71.19% of patients and minimum disability for 28.81% of them. BREAST-Q Aesthetic Questionnaire obtained 92.72%. No patient developed Baker III or IV capsular contracture.Conclusions:LDMF with implant is a reliable and safe procedure for 1-step breast reconstruction after SM for recurrent cancer in radiated breast. It entails a low rate of major complications, achieving stable and pleasant results without significant upper limb functional impairment, also for elderly women and larger breasts. Thus, a definite role is yet predictable for this flap in the setting of SM in all cases not suitable for free-flap reconstruction.

Sternal resection and reconstruction for metastasis due to breast cancer: the Marlex sandwich technique and implantation of a pedicled latissimus dorsi musculocutaneous flap

BackgroundThe treatment of hemotogenous solitary sternal metastases by breast cancer remains a controversial issue. Sternal resection for select patients might provide good long-term local control.Case presentationA 63-year-old woman was admitted to our hospital with a mass at the sternum and right second to third costochondral cartilage. She had undergone bilateral mastectomy for breast cancer 13 years earlier. A percutaneous biopsy was performed, and the mass was diagnosed as solitary metastasis due to breast cancer. She received two courses of weekly paclitaxel and bevacizumab, and computed tomography (CT) revealed shrinking of the mass in the sternum. We performed surgical resection with curative intent for a multimodality approach. Parasternectomy and removal of the right second and third costochondral cartilage was performed. A prosthesis was created to fill the defect by sandwiching molded methylmethacrylate between polypropylene mesh. The prosthesis was fixed to the cut ends of the costochondral cartilage and the residual sternum. Finally, a harvested latissimus dorsi myoctaneous flap was transpositioned to cover the chest midline wound. Negative surgical margins at the stump of the sternum and costochondral cartilage were revealed.ConclusionParasternal resection and reconstruction by the Marlex sandwich technique and implantation of a pedicled latissimus dorsi myocutaneous flap for metastasis due to breast cancer was safely performed.

Technique and Outcomes of Pedicled Latissimus Dorsi Myocutaneous Flap for Oncologic Defects Around the Clavicle

The authors present a retrospective review of 7 patients who underwent wide excision of the malignant tumors around the clavicle. Patient demographics, clinical details, the arc of rotation, outcome, and complications were analyzed.

Volume Change of Pedicled Latissimus Dorsi Muscle Flap after Partial Breast Reconstruction.

Despite successful breast reconstruction with oversized latissimus dorsi muscle flap after breast-conserving surgery for breast cancer, esthetic problems continue to exist due to flap shrinkage. The purpose of this study was to evaluate the objective volume change of pedicled latissimus dorsi muscle flap when it is used in breast reconstruction. Patients who were diagnosed with breast cancer and underwent a breast-conserving surgery with immediate breast reconstruction with pedicled latissimus dorsi myocutaneous flap between October 2009 and November 2015 were studied. Eleven patients who were followed up for more than 1 year after operation were included in the study. We evaluated the volume of muscle portion of the latissimus dorsi myocutaneous flap with computed tomography (CT) scan. We analyzed the rate of volume change of the latissimus dorsi muscle every year until 5 years after the operation. The latissimus dorsi muscle flaps of all 11 patients showed a volume decrease over time. The rate of volume change of the latissimus dorsi muscle flaps decreased 8.04% in the first year, 6.36% in the second year, 5.05% in the third year, 2.88% in the fourth year, and 2.56% in the fifth year after operation in average. This research shows the possibility of objectively evaluating the volume change of pedicled latissimus dorsi muscle flaps after breast reconstruction. The findings will be helpful in designing the size of the flaps to use on defects after breast-conserving surgery.
