Current Global Trends in Prepectoral Breast Reconstruction.

Implant-based breast reconstruction (IBBR) is the most frequently performed procedure for breast reconstruction following mastectomy, which involves the surgical placement of breast implants. The approach to breast reconstruction can be divided into two main categories, namely prepectoral breast reconstruction (PPBR) and subpectoral breast reconstruction (SPBR), based on the implant plan and placement technique. In recent years, there has been a significant surge in the popularity of prepectoral implant-based breast reconstruction, where the implants are positioned above the chest muscle, as opposed to beneath it in the subpectoral approach. However, despite this growing preference, there is a lack of comprehensive data regarding the national trends in the utilization of this technique, thus necessitating further investigation. This narrative review aims to ascertain the current global patterns linked to prepectoral breast reconstruction and elucidate the considerations surrounding patient and implant selection, reconstructive techniques, the utilization of meshes in prepectoral reconstruction, the ensuing outcomes and complications, the ramifications of radiotherapy, and the potential advantages of integrating fat infiltration into the implementation of this technique in breast reconstruction with a focus on published papers in last five years. Conclusion: Prepectoral breast reconstruction has emerged as an appropriate surgical option for individuals seeking breast reconstruction. This development can be attributed to the recent progress made in implant technology, which has significantly enhanced the outcomes of this procedure. Additionally, advancements in mastectomy techniques, autologous fat grafting, and the use of acellular dermal matrices (ADMs) have also played a vital role in improving the aesthetic results of prepectoral breast reconstruction. As a result, the significance and effectiveness of this technique in the field of breast reconstruction have been firmly established, making it an essential component of the overall armamentarium available to plastic surgeons for breast reconstruction purposes.

Pectoralis Major Muscle Flap Utilization in Salvage Esophagectomy Including Great Vessel Resection Reconstructed by Prosthetic Grafts.

BACKGROUND: Salvage surgery is a therapeutic option for recurrent or residual esophageal cancer after definitive chemoradiation therapy. This report aimed to describe the procedure of reconstruction after salvage esophagectomy involving great vessel resection using prosthetic grafts, a pectoralis major muscle (PM) flap, and free jejunal transfer, if required. To the best of our knowledge, no previous report has described the reconstruction of the defect after combined esophageal and great vessel resection. PATIENTS AND METHODS: From January 2017 to December 2022, 4 patients underwent salvage esophagectomy with excision of the great vessels and reconstruction with prosthetic grafts, as well as a PM flap placement in a single center. We retrospectively investigated the patients' clinical data. The patients were all men, with a median age of 70 (range, 67-77) years. Regarding neoadjuvant therapy, 2 patients received chemoradiation therapy, 1 patient received radiotherapy only due to drug-induced pneumonia, and 1 patient received chemotherapy with adjuvant radiotherapy. RESULTS: Alimentary tract reconstruction was performed by free jejunal transfer in 2 cases, direct suture in 1 case, and stomach roll in 1 case. In all cases, a vascular bypass was established before tumor resection. We created mediastinal tracheostoma in 2 cases. A PM flap was inserted to cover the prosthetic grafts and approximate the tracheal mucosa. With regard to major complications, leakage from the jejunal esophageal anastomotic site was observed in 2 cases. The leakage improved with conservative treatment without graft removal or replacement in both cases. CONCLUSIONS: In cases of locally recurrent or residual tumors after definitive chemoradiation therapy, salvage esophagectomy along with great vessel resection, followed by reconstruction using prosthetic grafts, PM flaps, and free jejunal transfer, if necessary, is a useful option.

Flap management following orthotopic heart transplantation: A single institution's review of 66 sternal wound complications.

BACKGROUND: Sternotomy wound complications are more frequent after orthotopic heart transplantation (OHT) compared to other cardiac surgeries, primarily due to additional risk factors, including immunosuppression. Flap closure often becomes necessary for definitive treatment, although there is a scarcity of data on the outcomes of sternal wound reconstruction in this specific population. METHODS: A retrospective analysis was conducted on 604 sternal wound reconstructions performed by a single surgeon between 1996 and 2023. Inclusion criteria comprised patients who underwent OHT as their primary cardiac procedure. Surgical interventions involved sternal hardware removal, debridement, and muscle flap closure. RESULTS: The study included 66 patients, with culture-positive wound infection being the most common indication for reconstruction (51.5%). The median duration between transplantation and sternal wound reconstruction was 25 days. Bilateral pectoralis major myocutaneous advancement flaps (n = 63), rectus abdominis flaps (n = 2), or pectoralis major turnover flaps (n = 1) were used. Intraoperative wound cultures revealed positivity in 48 patients (72.7%), with Staphylococcus epidermidis being the most frequently cultured organism (25.0%). The overall complication rate was 31.8%, and two patient deaths were related to sternal wounds, resulting from multiorgan failure following septic shock. The majority of the patients reported excellent long-term functional and esthetic outcomes. CONCLUSIONS: Sternal wounds following OHT pose a significant morbidity risk. Our strategy focuses on immediate and aggressive antibiotic therapy, thorough debridement, and definitive closure with bilateral pectoralis myocutaneous advancement flaps. This approach has demonstrated complication and mortality rates comparable to the general cardiac surgery population, as well as excellent functional and esthetic results.

Pectoralis major pedicle bone grafting vs. tricortical iliac grafting for Neer 4-part proximal humerus fractures: a randomized controlled trial.

BACKGROUND: The risk of avascular necrosis, nonunion, or malunion is high in osteoporosis-related 4-part fractures. We evaluated the results of patients who underwent plate osteosynthesis with a vascularized pectoralis major graft compared with tricortical iliac grafting to treat 4-part proximal humerus fractures. MATERIAL AND METHODS: Thirty-four patients aged 50-75 years with Neer 4-part proximal humerus fractures were studied. Group A (n = 17) underwent osteotomy of a 2.5 ± 1 cm pectoralis major pedicle bone graft and plate application, whereas group B (n = 17) underwent plate osteosynthesis using iliac autogenous grafts. Final follow-up assessments included evaluation using Constant and American Shoulder and Elbow Surgeons scoring systems, humeral neck-shaft angle (HNSA), humeral head height, and humeral head avascular necrosis. RESULTS: Reduction loss was observed in 3 patients (17.6%) in group A, whereas it was observed in 10 patients (58.8%) in group B (P = .013). Humeral head avascular necrosis was found in 1 patient (5.8%) in group A, whereas it was found in 5 patients (29.4%) in the other group (P = .071). The HNSA was normal in 12 (70.5%) of group A patients, whereas it was normal in 6 (35.2%) of group B patients. The HNSA was weak or bad (<1200) in 29.4% of group A patients, whereas this rate was 64.7% in group B patients. Humeral head height was 2.64 ± 1.45 mm in group A and 3.66 ± 1.65 mm in group B. There were no statistically significant differences between the 2 groups in terms of Constant and American Shoulder and Elbow Surgeons scoring systems. CONCLUSION: Pectoralis major bone pedicle graft in Neer 4-part proximal humerus fractures reduces the risk of avascular necrosis and nonunion rates. Our technique yielded excellent clinical and radiological results. We achieved recovery without creating additional donor site morbidity.

Preservation of the pectoralis major fascia has no impact on the long-term oncologic outcomes of patients with breast cancer treated with conservative mastectomy and immediate breast reconstruction: A propensity score matching analysis.

BACKGROUND: The oncologic safety of preserving the pectoralis major fascia (PMF) in patients with breast cancer remains controversial. In this study, we aimed to determine the impact of preserving the PMF on long-term oncologic outcomes in patients with breast cancer treated with immediate implant-based breast reconstruction (IBBR) following conservative mastectomy. METHODS: We selected women with early-stage breast cancer who underwent conservative mastectomy and submuscular IBBR in our center during 2014-2019. The propensity score matching method was used to create well-balanced fascia-preserved and fascia-removed groups. Locoregional recurrence-free survival (LRFS), disease-free survival (DFS), distant metastasis-free survival (DMFS), and overall survival (OS) rates were calculated using the Kaplan-Meier method and compared using log-rank tests between the fascia-preserved and fascia-removed groups. RESULTS: After matching, there were 219 patients in each group. The mean follow-up time was 64.8 ± 18.1 months for the fascia-preserved group and 64.9 ± 18.4 months for the fascia-removed group. There were no significant differences between the groups in terms of LRFS (91.3% vs. 93.8%; p = 0.818), DMFS (94.0% vs. 92.3%; p = 0.056), DFS (89.9% vs. 88.4%; p = 0.261), and OS (95.8% vs. 95.4%; p = 0.783) rates. In the fascia-preserved group, 61.5% of the locoregional recurrence events occurred within 2 years after surgery. CONCLUSION: Preservation of the PMF did not significantly impact the long-term oncologic outcomes in patients with breast cancer who underwent conservative mastectomy and IBBR. The PMF might be safely preserved in patients without suspicious tumor invasion into this fascia.

Managing the animation deformity in breast reconstruction transposing the implant to a partial prepectoral pocket: Early experience and preliminary results with a new technique.

BACKGROUND: Two-stage implant-based breast reconstruction remains the most commonly used technique for rebuilding a breast. Subpectoral implant placement minimizes complications, such as capsular contracture, implant visibility, malposition, and extrusion. Nevertheless, it is associated with high animation deformity (AD). Prepectoral reconstruction eliminates AD but is subject to a higher risk of implant extrusion and visibility. In this prospective, single-center study we present a new technique aimed to create a new hybrid pocket in which the upper portion of the implant is placed subcutaneously, whereas its inferior pole is still covered by a pectoralis muscle sling reducing implant lower pole visibility and palpability. MATERIAL AND METHODS: In each case, the prosthesis was removed and a new hybrid pocket was created by splitting the muscle into two portions, separating its cranial part from the overlying subcutaneous tissue and anchoring it back to the chest wall. The caudal muscle sling was left adherent to the subcutaneous tissue of the central part of the breast. Patient outcomes were evaluated with a BREAST-Q questionnaire preoperatively and 1 year after surgery. RESULTS: Forty-eight patients with severe postoperative breast animation were enrolled (8 bilateral and 40 unilateral). No major complications occurred. After a 1-year follow-up, the aesthetic and functional satisfaction rate was high and a good implant coverage was achieved. No residual AD of the breast was observed. CONCLUSIONS: Changing the implant placement from the subpectoral to a partially subcutaneous plane, both severe AD and implant extrusion can be avoided, expanding the indications for safe prosthetic breast reconstruction. LEVEL OF EVIDENCE: Level of evidence IV.

Pectoralis Major Muscle Morbidity After Submuscular Silicone-based Breast Reconstruction: A Systematic Review.

Silicone implants or tissue expanders placed under the pectoralis major (PM) muscle are often used for breast reconstruction. However, the disruption of PM insertions, which is often an inevitable part of the surgical procedure, is known to cause PM morbidity and, subsequently, problems with the use of the ipsilateral arm. In this systematic review, we present current knowledge regarding the effect of submuscular silicone-based breast reconstruction on the function of PM and the ipsilateral arm. A search of the relevant English literature was performed through PubMed and ten eligible studies were identified. Articles reporting breast augmentation were accepted as the techniques of implant insertion are similar to reconstruction. Questionnaires reporting the status of the arm, analysis of the range of motion of the shoulder with 3-D video, isometric or isokinetic dynamometry, ultrasound shear-wave elastography, volumetric MRI, electromyography and light and electron microscopy of the PM fibers were used for the assessment of PM and arm status. The insertion of implants under the PM, especially when combined with dissection of some of its insertions, seems to be associated with measurable abnormal microscopic, imaging, and dynamometric findings. However, the intact part of the muscle and possibly other nearby muscular structures are able to compensate for the lost part of PM. Thus, the insertion of implants fully or partially under the PM seems to have no or little effect on the function of the ipsilateral upper limb in daily life.

Arthroscopic Pectoralis Minor Release After Reverse Shoulder Arthroplasty: A Novel Consideration for Postarthroplasty Pain.

CASE: A 74-year-old male patient presenting with chronic radiating shoulder pain, paresthesias, and weakness had previously undergone reverse shoulder arthroplasty and anterior cervical discectomy and fusion for an irreparable cuff tear and cervical radiculopathy, respectively. After being diagnosed with neurogenic thoracic outlet syndrome and undergoing physiotherapy, the patient's recalcitrant condition was surgically managed with arthroscopic pectoralis minor tenotomy, suprascapular nerve release, and brachial plexus neurolysis. CONCLUSION: This ultimately led to complete pain relief and improved function. By sharing this case, we aim to shed light on this overlooked pathology and help prevent unnecessary procedures for others suffering from similar conditions.

Pectoralis major rupture in body builders: a case series including anabolic steroid use.

BACKGROUND: Rupture of the pectoralis major (PM) muscle is a rare injury, with increasing incidence over the last decades, mainly due to participation in weightlifting and contact sports. Surgical management of PM injuries has been related with superior functional outcome, faster return to activities, better cosmesis and higher level of patients' satisfaction. The aim of the study is to present our experience in the management of this rare clinical entity and to correlate the use of anabolic steroids in the occurrence of the injury and the impact of type of injury, method of reconstruction and anabolic steroids on the post-operative outcome. CASES: We present a series of six male bodybuilding athletes who sustained PM rupture during weightlifting. We recorded the location & type of injury, the history and type of anabolic steroids use, the method of repair and the post-operative outcome. TREATMENT AND OUTCOMES: The mean follow-up period was 16 (12-24) months. All patients treated surgically had excellent results according to Bak criteria and returned to full activity within 5.4 (5-7) months following surgical reconstruction. No post-operative complications were recorded, despite the continued use of anabolic steroids, however one patient died from myocardial infarction within a year of surgical treatment. CONCLUSIONS: PM rupture is an injury with increasing incidence within bodybuilding athletes probably not related to the dominance of the limb. Fixation of the tendon with suture anchors results in excellent clinical outcome and patient's satisfaction postoperatively regardless the chronicity of the repair. Our observations in these cases suggest that anabolic steroids use may contribute to the injury due to an excessive upward adjustment of the athlete's goals in lifting weights and moreover the continuation of administration even in the recovery period does not seem to have a negative effect either on the time or on the level of adequate functional recovery postoperatively.

A Review of 559 Sternal Wound Reconstructions at a Single Institution: Indications and Outcomes for Combining an Omental Flap With Bilateral Pectoralis Major Flaps in a Subset of 17 Patients With Infections Extending Into the Deep Mediastinum.

BACKGROUND: Sternal wound infection (SWI) and dehiscence after median sternotomy for cardiac surgery remain challenging clinical problems with high morbidity. Bilateral pectoralis major myocutaneous flaps are excellent for most sternal wounds but do not reach deeper mediastinal recesses. The omental flap may be a useful adjunct for addressing these deeper mediastinal infections. METHODS: Records of 598 sternal wound reconstructions performed by a single surgeon (J.A.A.) from 1996 to 2022 were reviewed. At the time of surgery, patients underwent sternal hardware removal, debridement, and closure with bilateral pectoralis major myocutaneous flaps. Pedicled omental flaps were also mobilized when additional vascularized tissue was required within the deeper mediastinum. RESULTS: Complete data were available for 559 sternal wound reconstructions performed by the senior author during this period. Bilateral pectoralis and omental flaps were mobilized in 17 of 559 (3.04%) patients. Common indications for initial cardiac surgery included repair or replacement of diseased aortic roots (9/17; 52.94%), aortic valves (8/17; 47.06%), and mitral valves (6/17; 35.29). Mean American Society of Anesthesiologists score was 3.56. Preoperative morbidity included culture-positive wound infection (12/17; 70.59%), dehiscence (15/17; 88.24%), wound drainage (11/17; 64.71%), and inability to close the chest after the original sternotomy because of hemodynamic instability (6/17; 35.29%). Intraoperative deep mediastinal or bone cultures were positive in 8 of 17 (47.06%) patients. Postoperative complications included partial dehiscence (2/17; 11.76%), skin edge necrosis (1/17; 5.88%), seroma (1/17; 5.88%), abdominal hernia (1/17; 5.88%), and recurrent infection (2/17; 11.76%). Three patients (17.65%) died within 30 days of the reconstruction surgery. CONCLUSIONS: Patients undergoing combined pectoralis major and omental flap closure frequently had a history of aortic root and valve disease, and other significant preoperative morbidities. However, postoperative complication rates after combined flap closure were relatively low. Combined pectoralis major and omental flap reconstruction thus appears to be an effective intervention in patients with sternal wounds extending into the deep mediastinum.

Pectoralis Major Muscle Belly Rupture in a 17-Year-Old Female Softball Player: A Case Report.

CASE: We report the case of a healthy 17-year-old female softball player with a subacute full-thickness intramuscular tear of the pectoralis major (PM) muscle. A successful muscle repair was obtained using a modified Kessler technique. CONCLUSIONS: Despite initially being a rare injury pattern, the incidence of PM muscle rupture is likely to increase as interest in sports and weight training increases, and although this injury pattern is more common in men, it is becoming more common in women as well. Furthermore, this case presentation provides support for operative treatment of intramuscular ruptures of the PM muscle.

Head and Neck Reconstruction With 2-Stage External Pectoralis Major Myocutaneous Flap Transfer.

BACKGROUND: In head and neck surgery cases where skin is severely scarred or adhered to surrounding tissue, reconstruction can be difficult to perform using microsurgical tissue or conventional pedicled pectoralis major myocutaneous flap (PMMF) transfer given the risks, which include damage to major vessels when manipulating scarred skin. For such cases, we perform a 2-stage external PMMF transfer, whereby the PMMF is directly sutured to the defect over the neck skin (without manipulation the hardened skin), and the flap division is then performed secondarily. METHODS: A total of 30 patients who had histories of radiotherapy (60-70 Gy) and prior neck dissection received the 2-stage external PMMF transfer procedure. Indications for the flaps included pharyngeal fistula closure in 12 patients, reconstruction for mandibular necrosis after radiotherapy in 8 patients, salvage surgery for partial or total necrosis of the free flap in 4 patients, and simultaneous reconstruction after tumor excision in 6 patients. Two patients underwent a second external PMMF transfer from the contralateral side because of postoperative complications, yielding a total of 32 flap transfers. RESULTS: Twenty-nine flaps showed complete flap survival, whereas 3 had partial necrosis. Other complications, despite complete flap survival, included large fistulas requiring additional surgery for fistula closure (1 patient) and small fistulas that were closed without requiring reoperation (7 patients). CONCLUSIONS: External PMMF transfer offers a safe, simple, and effective option in cases where free flap surgery is considered difficult or the risks associated with neck manipulation are high.

Risk stratification in subpectoral to prepectoral pocket conversion to reduce post-reconstruction animation deformity.

BACKGROUND: Animation deformity is a morbid complication that impacts women undergoing subpectoral implant-based breast reconstruction. Transferring implants from the subpectoral to prepectoral space, pocket conversion, can be performed to minimize this issue. While prior literature has evaluated outcomes associated with this procedure, we investigated the risk factors most commonly associated with post-conversion complications. METHODS: We performed a retrospective cohort investigation of women undergoing prepectoral pocket conversion. Pre-conversion clinical characteristics and surgical complications (major and minor) were collected. Predictors for postoperative complications were identified using univariate and multivariate logistic regression models. Odds ratios (OR) and adjusted odds ratios (aOR) are presented with 95% confidence intervals, and p-values were assessed at α = 0.05. RESULTS: A total of 34 patients (63 breasts) were included. Pocket conversion relieved animation deformity in all breasts. The overall rates of major and minor complications were 14.3% (n = 9/63) and 34.9% (n = 22/63), respectively, by mean follow-up of 11.1 months. After adjusting for confounders, pre-conversion implant rupture (OR= 6.00, CI= 0.99-34.58; aOR= 12.8, CI= 1.15-170.32) and duration of implant placement (OR=1.35, CI= 1.07-1.78; aOR= 1.1, CI= 1.00-1.21) were found to be significant predictors of major postoperative complications. CONCLUSION: With a fairly inclusive patient population, this series provides data for improved risk stratification of patients considering conversion to relieve animation deformity. Interestingly, traditional risk factors (namely, body mass index and smoking status) were not significant predictors for postoperative complications, suggesting that conversion may be safe in high-risk patients. Such data support more informed preoperative counseling and wider application of this procedure.

Pectoralis Major Myocutaneous Flap Revisited as a Workhorse for Reconstruction for Defects in the Upper Arm: A Case Report.

Many previous reviews of the literature have described the grafts and techniques for management of defects in the upper arm. However, the alternatives are limited in cases where some conventional flaps are not available and the nearby donor vessels have been previously sacrificed for free flaps. A 77-year-old man presented with a tumor in the right upper arm just above the axilla. The patient had already undergone surgeries for three recurrences of low-grade myxofibrosarcoma, the primary site of which was around the right scapula. The pectoralis major musculocutaneous flap was used for the defect caused by tumor resection, since there was no other available option. An acceptable result was obtained without any major complications. Thus, the pectoralis major myocutaneous flap may be a candidate for reconstruction of defects in the proximal part of the upper arm.

Pectoralis major rupture repair with Achilles tendon allograft in 22 bodybuilding athletes.

BACKGROUND: Pectoralis major tendon rupture rate is increasing due to increased tendency to bodybuilding exercises, specially the bench press workout, and weight-lifting. The aim of this study was to determine the results of pectoralis major rupture repair with Achilles tendon allograft in bodybuilding athletes. METHODS: In this case series study, 22 bodybuilding athlete patients (24 pectoralis major ruptures) were undergone open surgical repair during January 2016 till December 2020. 21 ruptures were chronic (2 ruptures were revision) and 3 ruptures were acute. Surgical method was based on Achilles tendon allograft used to augment the ruptured site for lengthening the shortened tendon.The results were analyzed using Bak's criteria and Constant score in pre operation visit and 6th and 12th months and in the last follow up. RESULTS: All cases were male with the mean age of 32.1 ± 5.4. The mean duration time between injuries to surgery was 37 ± 46 month (1-182 months). Return to professional sport began at 10.9 ± 2.8 months after surgery in which 16 cases (66.7%) have returned to their pre surgery bench press workout records. No infection or hematoma occurred. At the final follow-up, Bak criteria demonstrated excellent, good and fair in 4, 18 and 2 shoulders respectively. The constant score increased from 87.9 ± 7.9 in pre operation visit to 92.7 ± 6.4 in the last follow up (P < 0.001). CONCLUSIONS: It seems that our surgical method is an effective approach in cases with acute or chronic pectoralis major ruptures. LEVEL OF EVIDENCE: Level IV.

Transferring pectoral muscle flap to depleted neck to create a new recipient source for free flaps in head and neck reconstruction.

INTRODUCTION: The thoracoacromial vessels (TA) are one of the options as recipient for free flaps in head and neck reconstruction when the neck is depleted. However, it has limitations such as need of vein graft or kinking and being under pressure on clavicle. The authors describe a new modification of using pectoral branch of TA as recipient vessel. PATIENTS AND METHODS: Between July 2019 and January 2022, 8 patients (1 female, 7 male) underwent head and neck reconstructions with free flaps. Age of patients ranged from 53 to 73 years old. All surgeries were because of SCC. Defects were including 3 total lower lip, 2 pharyngoesophageal defects, 1 cheek, lower and upper lip, 1 mandible, cheek and mount floor and 1 tongue and mount floor. Defects were between 12 × 5 cm and 21 × 9 cm. Pectoral branch of TA was transposed to the depleted neck as pectoral muscle flap to prevent kinking and pressure. Over the clavicle, the proximal root of the pedicle of muscle was found and dissected distally until tensionless anastomoses could be accomplished between the muscle and free flaps. ALT, MSAP, and Radial forearm free flaps were used as free flaps. In one patient the fibula and ALT flaps were used as flow through so the pedicle of ALT flap was anastomosed to pectoral muscle pedicle. Pectoral muscle was rotated 180° on its horizontal axis after finishing anastomoses to guard anastomoses from radiated neck skin. Muscle was fixed to sternocleidomastoid muscle with sutures to maintain its position. All donor sites were closed primarily. RESULTS: The diameter of recipient artery was between 1 and 1.6 mm. The veins were approximately same as arteries. All anastomosis were performed end-to-end fashion. Three patients needed skin grafts to closure of tight radiated neck skin. Complications as 1 hematoma and 1 wound dehiscence were salvaged successfully. All flaps survived. Patients were followed up between 2 and 6 months. Our first patient died at post-operative 6th month so long follow-up could not be achieved. The final outcomes such as chewing, oral competence and swallowing were successful for remaining patients. CONCLUSION: Transposing TA as pectoral muscle flap to the neck can decrease need of vein graft and prevent kinking or pressure of the pedicle on the clavicle.

Novel Diagnostic and Treatment Techniques for Neurogenic Thoracic Outlet Syndrome.

Neurogenic thoracic outlet syndrome is a challenging condition to diagnose and treat, often precipitated by the triad of repetitive overhead activity, pectoralis minor contracture, and scapular dyskinesia. The resultant protracted scapular posture creates gradual repetitive traction injury of the suprascapular nerve via tethering at the suprascapular notch and decreases the volume of the brachial plexus cords and axillary vessels in the retropectoralis minor space. A stepwise and exhaustive diagnostic protocol is essential to exclude alternate pathologies and confirm the diagnosis of this dynamic pathologic process. Ultrasound-guided injections of local anesthetic or botulinum toxin are a key factor in confirming the diagnosis and prognosticating potential response from surgical release. In patients who fail over 6 months of supervised physical therapy aimed at correcting scapular posture and stretching of the pectoralis minor, arthroscopic surgical release is indicated. We present our diagnostic algorithm and technique for arthroscopic suprascapular neurolysis, pectoralis minor release, brachial plexus neurolysis, and infraclavicular thoracic outlet decompression.

Pectoralis Major Tendon Rupture While Bouldering.

Pectoralis major tendon ruptures are rare injuries. We present a case of a pectoralis major tendon rupture incurred while bouldering that required surgical repair. The diagnosis of pectoralis major tendon rupture relies predominantly on clinical examination. Among athletes, outcomes after surgical repair are superior to those after nonoperative therapy in most cases of complete tendon rupture. Although infrequent, pectoralis major tendon ruptures can occur while climbing, and early recognition and expedited surgical treatment are paramount to maximize functional recovery.

[Effect of the Hyoid Bone Suspension Technique on the Preservation of Swallowing Function after Total Glossectomy and Pectoralis Major Musculocutaneous Flap Reconstruction for Locally Advanced Tongue Cancer].

Dysphagia is a major postoperative complication in patients with locally advanced oral cancer. In this case report, we describe the effect of the hyoid bone suspension technique on the preservation of swallowing function after total glossectomy and pectoralis major musculocutaneous flap reconstruction for locally advanced tongue cancer. Case: A 72-year-old Japanese male was diagnosed with advanced squamous cell carcinoma on the left side of his tongue(cT4aN2cM0, cStage ⅣA). Under general anesthesia, the patient underwent a tracheotomy, bilateral modified radical neck dissection type Ⅲ, total glossectomy, and reconstruction with a left pectoralis major musculocutaneous flap(PMMC flap). Intraoperatively, the PMMC flap was designed to have a heart shape of 11×6 cm and was elevated. Subsequently, holes were made at the lower edge of the mandible, and the hyoid bone was suspended and fixed to the mandibular border using 2-0 nylon sutures. The postoperative course was uneventful; the flap was completely engrafted and was in good condition. The hyoid bone suspension technique can reproduce the pharyngeal phase of swallowing, and the palatal augmentation prosthesis helps to improve food mass feeding and preserve the swallowing function.
