Introduction: In 1977, based on anatomical studies by McCraw et al., the pectoralis major muscle began to be used as an island myocutaneous flap. The present article describes a case of reconstruction of a defect in the anterior wall of the right hemithorax using the pectoralis major myocutaneous flap in an ipsilateral island. Case Report: AES, 66 years old, male, underwent wide resection of a recurrent infiltrative basal cell carcinoma measuring 13.0 x 8.0 cm in the right parasternal region. The myocutaneous flap was transposed through subcutaneous tunneling and the scars were positioned in the shape of an inverted T mammoplasty. Conclusion: This surgical tactic is easy to perform for surgeons accustomed to breast reconstruction, has a short surgical time, and has satisfactory aesthetic-functional results.
ABSTRACT
OBJECTIVES & AIMS:• To evaluate the outcome of different Reconstructive surgery in oral cavity carcinoma• To determine the factors which increase the complication in post op reconstructive surgery(like – diabetes, hypertension, smoking etc.)• The effect of flap transfer on complication or on post op rehabilitation of patients in oralcavity carcinoma.MATERIALS AND METHODS: This is a prospective study conducted at GCS hospital,Ahmedabad between oct. 2021 to June 2022. Sample size is 40 patients with case of oral cavitycarcinoma, out of which some cases underwent for PMMC Flap, Radial forearm free flap, ALTfree flap, fibula flap, forehead rotational flap, deltopectoral flap and local flap.CONCLUSION:Risks have not increased complications in PMMC or Free flap group in our study. Various otherstudies have similar results however a larger patient pool may be needed to assess them. ThePMMC flap is more favorable for patients with possibly lethal pre-op morbidities, when a longoperation is not advisable and a small defect is expected as compared to the longer operationduration of ALT free flap & Radial free flap.Though the flap related complications & donor site related complications are more with foreheadrotational flap as compared to PMMC. ALT & Radial forearm free flap, statistically there is nosignificant difference. Also, in the functional post-op outcomes there is minimally statisticallysignificant difference with PMMC flap, ALT free flap or Radial free flap, local flaps and otherreconstructive surgery.

ABSTRACT
Abstract Introduction A refractory cervical anastomotic fistula which postoperatively remains unhealed for more than 2 months under conservative care severely impacts the quality of life of the patient and potentially leads to anastomotic stricture after the fistula heals. It is widely accepted that, to avoid this complication, refractory cervical anastomotic fistulas should undergo more aggressive treatments. However, when and which surgical intervention should be considered is unclear. Objective This study was designed to evaluate the role of the pectoralis major myocutaneous flap in the management of refractory cervical anastomotic fistulas based on our experience of 6 cases and a literature review. Methods Six patients diagnosed with refractory cervical anastomotic fistula after esophagectomy treated using pectoralis major myocutaneous flap transfer were included in the study. The clinical data, surgical details, and treatment outcome were retrospectively analyzed. Results All patients survived the operations. One patient who had a circumferential anastomotic defect resulting from surgical exploration developed a mild fistula in the neo-anastomotic site in the 5th postoperative day, which healed after 7 days of conservative care. This patient developed an anastomotic stricture which was partially alleviated by an endoscopic anastomotic dilatation. All the other 5 patients had uneventful recoveries after operations and restored oral intake on the 10th-15th days after operation, and they tolerated normal diets without subsequent sequelae on follow-up. One patient developed both local and lung recurrence and died in 15 months after operation, while the other 5 patients survived with good tumor control during the follow-up of 25-53 months. Conclusion The satisfactory treatment outcome in our study demonstrates that pectoralis major myocutaneous flap reconstruction is a reliable management modality for refractory cervical anastomotic fistulas after esophagectomy, particularly for those patients who experienced persistent fistulas after conservative wound care and repeated wound closures.
Resumo Introdução Uma fístula anastomótica cervical refratária, que permanece sem cicatrização por mais de 2 meses sob cuidados conservadores, afeta gravemente a qualidade de vida do paciente e potencialmente causa estenose anastomótica após a cicatrização da fístula. É amplamente aceito que as fístulas anastomóticas cervicais refratárias devem ser submetidas a tratamentos mais agressivos. No entanto, quando e qual intervenção cirúrgica deve ser considerada ainda é incerto. Objetivo Avaliar o papel do retalho miocutâneo do peitoral maior no manejo de fístula anastomótica cervical refratárias com base em nossa experiência de 6 casos e uma revisão da literatura. Métodos Foram incluídos no estudo seis pacientes diagnosticados com fístula anastomótica cervical refratária após esofagectomia tratados com transferência de retalho miocutâneo do peitoral maior. Os dados clínicos, detalhes cirúrgicos e resultado do tratamento foram analisados retrospectivamente. Resultados Todos os pacientes sobreviveram às cirurgias. Um paciente com defeito anastomótico circunferencial, resultante da exploração cirúrgica, desenvolveu uma fístula leve no sítio neoanastomótico no 5° dia de pós-operatório, que foi resolvida após 7 dias de tratamento conservador. Esse paciente desenvolveu uma estenose anastomótica parcialmente aliviada por uma dilatação endoscópica anastomótica. Todos os outros 5 pacientes tiveram recuperações sem intercorrências após as cirurgias, restabeleceram a ingestão oral 10 ou 15 dias após a operação e toleraram dietas normais sem sequelas subsequentes no seguimento. Um paciente desenvolveu recorrência local e pulmonar e morreu 15 meses após a cirurgia, enquanto os outros 5 pacientes sobreviveram com bom controle tumoral durante o seguimento de 25 a 53 meses. Conclusão O resultado satisfatório do tratamento em nosso estudo demonstra que a reconstrução com o retalho miocutâneo do peitoral maior é uma modalidade de manejo confiável para as fístula anastomótica cervical refratárias após a esofagectomia, particularmente nos pacientes que apresentaram falha após o tratamento conservador das feridas cirúrgicas e com fechamento repetido delas.
ABSTRACT
Ansa pectoralis is the loop of communication between medial and lateral pectoral nerves, seen anterior to the second part of axillary artery. It carries C7 ?bres from the lateral cord to the medial pectoral nerve and supplies sternocostal part of pectoralis major muscle. Its damage can cause weakness of the sternocostal part of pectoralis major muscle. Section of the ansa pectoralis is done as a treatment modality to reduce spasm of pectoralis major after strokes. It is also used as nerve graft. There are only few articles which describe the anatomy of Ansa pectoralis. We conducted a dissection study in 36 pectoral regions of embalmed human cadavers to ?nd out the number, location, formation and branches of Ansa pectoralis. During dissection of the pectoral region, the formation of Ansa was seen to be of four different types. 72.2%(26 out of 36) was either between inferior or deep branch of lateral pectoral nerve and medial pectoral nerve or between the inferior lateral pectoral nerve and medial pectoral nerve (type A). In 6 cases (16.7%) it was between trunk of the lateral pectoral nerve and medial Pectoral nerve (type B). In 3 cases (8.3%), it was arising from lateral cord itself (Type C). In one case (2.7%) it was found to be arising from trunk and inferior branch of lateral pectoral nerve (Type D). The communicating loop was on the axillary artery in about 52.8% percentage of specimens, distal and plastered to the deep surface of pectoralis minor muscle in the 30.5% and multiple in 16.7%. The anatomy of Ansa pectoralis shows many variations. These are important while planning surgeries in pectoral region like breast augmentation, pectoral nerve blocks and harvesting pectoral nerve grafts.
ABSTRACT
ABSTRACT Objective: This study aims to assess a new technique used for pectoralis major reconstruction using bone tunnel and fixation with metallic anchors in the contralateral cortical bone. Methods: Patients who had undergone post-surgical reconstruction of the pectoralis major at least 24 months before were assessed by the UCLA Shoulder Score and the Simple Shoulder Test and compared with the contralateral side by manual goniometry. Subgroup analysis was also performed between grafted and non-grafted patients. Results: 13 patients fulfilled the inclusion criteria. The average UCLA score was 34.77 ± 0.12, compared with the standard 27 of good and excellent results p < 0.0001. The Simple Shoulder test mean was 11.92 ± 0.08. Grafted and non-grafted subgroups had no statistical differences for UCLA p = 0.58 and Simple Shoulder Test p = 1.00. Long term losses for elevation or external rotation were lower than 5º. No lesions recurred. All patients returned to their physical activities with no restrictions. Conclusion: The pectoralis major reconstruction technique using a bone tunnel and metallic anchors in the contralateral cortical bone was effective. However, its execution needs special care to avoid complications. Level of Evidence IV, Case Series.
RESUMO Objetivo: Avaliar, em uma série de casos, o uso da técnica de reconstrução do músculo peitoral maior através de túnel ósseo na cortical umeral anterior, feito no local de inserção original desse tendão, com fixação tendínea, usando âncoras metálicas na cortical contralateral. Métodos: Foram avaliados pacientes com mais de 24 meses depós-operatório de reconstrução do tendão do peitoral maior através do escore da UCLA, do teste simples de ombro e da goniometria manual comparativa com o lado contralateral. Foram também avaliados e comparados os subgrupos uso de enxerto versus sem enxerto usando os testes de qualidade de vida e goniometria mencionados acima. Resultados: De todos os pacientes operados pelo cirurgião sênior do serviço, 13 alcançaram os critérios de inclusão e foram incluídos nesse trabalho. O escore da UCLA foi de 34,77 ± 0,12, comparado com o padrão 27 de bons e ótimos resultados p < 0,0001. A média para o teste simples de ombro foi de 11,92 ± 0,08. Com relação ao uso de enxerto, não houve diferenças entre os subgrupos com e sem enxerto, p = 0,62 para o escore da UCLA e p = 0,35 para o teste simples de ombro. Não houve perda de elevação ou rotação externa superior a 5º nem relesões. Todos os pacientes retornaram às atividades físicas. Conclusão: A técnica de reconstrução do tendão do peitoral maior com túnel ósseo e fixação na cortical contralateral com âncoras demonstrou-se efetiva, mas sua execução necessita cuidado afim de evitarem-se complicações.

ABSTRACT
SUMMARY: The variations in the serratus anterior (SA) muscle are common. Here, we report a rare variation of the muscle origin with a potentially great clinical implication. We found an aberrant SA variation in an 81-year-old Korean male cadaver during a routine dissection for medical students. Additional slip (AS) of the SA originated from the clavipectoral fascia and the pectoralis minor. It traveled inferiorly and merged to the typical SA part. Precise knowledge about SA variations is clinically valuable; therefore, clinicians should be aware of the possible variation.
RESUMEN: Las variaciones en el músculo serrato anterior (MSA) son comunes. En este trabajo informamos una variación rara del origen muscular con una implicación clínica potencialmente importante. Encontramos una variación aberrante del MSA en un cadáver masculino, coreano de 81 años, durante una disección de rutina para estudiantes de medicina, con un fascículo adicional del MSA originado en la fascia clavipectoral y el músculo pectoral menor. Este fascículo se dirigió inferiormente y se fu- sionó con la parte común de MSA. El conocimiento preciso sobre las variaciones de MSA es útil clínicamente; por lo tanto, los médicos deben ser conscientes de esta posible variación.

Objective:To explore the advantages and value for clinical application of clavicle segment osteotomy approach with pectoralis major muscle pedicle in surgical resection of posterior brachial plexus tumour.Methods:From April 2010 to December 2020, 6 patients with brachial plexus tumour behind the clavicle were treated. Two patients had the tumour on the left brachial plexus and 4 on the right. Two patients had the tumours located in the upper trunk of brachial plexus, 2 in the middle trunk, 1 in the medial plexus and 1 in the posterior bundle. The neurological function evaluation were grade II in 3 cases and grade III in 1 case preoperatively. The tumours sized from 3.0 cm× 3.0 cm×2.0 cm to 11.0 cm×8.0 cm×6.0 cm. The clavicular segment osteotomy approach with the pedicle of the pectoralis major was applied in order to expose the surgical field and remove the nerve tumour. All patients underwent regular postoperative outpatient clinic follow-up to record the sensation of the affected limb and the recovery of muscle strength, tumour recurrence and fracture healing.Results:In the operation, it was found that there was still a little glial-like tissue in the nerve sheath after complete dissection of the tumours in 2 patients. Postoperative pathological examination reported that there were 4 schwannoma, 1 malignant peripheral schwannoma and 1 neurolipoma. The postoperative follow-up lasted for 6 to 34 months, with an average of 12.8 months. All patients showed no symptoms of brachial plexus injury or tumour recurrence. The clinical symptoms were relieved or disappeared. The neurological function evaluation reached grade III in 5 patients and grade IV in 1 case. At the same time, the internal fixation of the clavicle was satisfactory and achieved bone union in all cases. Fracture healing time was 2.5 to 4.5 months, with an average of 3.2 months. The internal fixation was removed from 3 patients after operation in 1 year. No obvious limb movement disorder and periarthritis of shoulder and other complications occurred.Conclusion:The transclavicular osteotomy approach with the pedicle of the pectoralis major can fully expose the anatomical alignment of the brachial plexus and the relationship adjacent and between the tumour and the surrounding tissues in the surgery for a brachial plexus tumour behind the clavicle, which is helpful for a complete tumour resection. It is a feasible method to treat brachial plexus tumour behind the clavicle by finding residual tumour-like tissue, reducing the risk of surgery and tumour recurrence, and providing excellent blood supply to the osteotomy segment of the clavicle to promote fracture healing.
ABSTRACT
Objective:To evaluate the optimization efficacy of transversus thoracic muscle plane block (TTPB)-pectoral nerve block (PECS) with compound lidocaine-general anesthesia for modified radical mastectomy for breast cancer.Methods:Ninety female patients, aged 40-64 yr, with American Society of Anesthesiologists physical status Ⅰ or Ⅱ and body mass index <30 kg/m 2, undergoing elective modified radical mastectomy for breast cancer, were divided into 3 groups ( n=30 each) using the random number table method: general anesthesia group (group C), TTPB-PECS with compound lidocaine-general anesthesia group (group L), and TTPB-PECS with ropivacaine-general anesthesia group (group R). The laryngeal mask was used for total intravenous anesthesia.PECS I, PECS II and TTPB were performed sequentially after laryngeal mask placement in L and R groups, and 0.4% compound lidocaine 15, 15 and 10 ml (group L) and 0.375% ropivacaine 15, 15 and 10 ml (group R) were injected at the above three points, respectively.Patient-controlled intravenous analgesia (PCIA) was performed with sufentanil at patient-controlled analgesia (PCA) dose of 2 ml/dose and a lockout time of 15 min at the end of operation, and when visual analog scale (VAS) score ≥ 3 points, sufentanil 5 μg was given intravenously for rescue analgesia.The intraoperative consumption of propofol and remifentanil, emergence time, and laryngeal mask removal time were recorded.The Ramsay sedation score and duration of postoperative analgesia were recorded at 10 min after removal of the laryngeal mask.The consumption of sufentanil, ratio of the effective pressing times to the total pressing times of PCA (D 1/D 2 ratio), requirement for rescue analgesia, and occurrence of adverse effects such as nausea and vomiting, skin pruritus, bradycardia, and respiratory depression within 48 h after surgery were recorded. Results:Compared with C group, the intraoperative consumption of propofol and remifentanil was significantly reduced, the emergence time and laryngeal mask removal time were shortened, Ramsay sedation scores was decreased, postoperative VAS scores were decreased, duration of postoperative analgesia was prolonged, D 1/D 2 ratios were increased, the consumption of sufentanil was reduced, and the requirement for rescue analgesia and incidence of postoperative nausea and vomiting were decreased in R and L groups ( P<0.05). Compared with R group, the duration of postoperative analgesia was significantly prolonged, D 1/D 2 ratio was increased, the consumption of sufentanil was decreased, and the requirement for rescue analgesia was decreased in L group ( P<0.05). Conclusions:Compared with general anesthesia, TTPB-PECS with compound lidocaine-general anesthesia used in modified radical mastectomy for breast cancer is helpful in achieving a low-opioid anesthetic mode, which is more conducive to suppressing postoperative hyperalgesia and promoting early postoperative recovery, and the optimization efficacy is more significant than that of ropivacaine.
ABSTRACT
Objective:To evaluate the impact of sarcopenia on survival and treatment-related toxicity in postoperative recurrent esophageal squamous cell carcinoma (ESCC) patients treated with chemoradiotherapy.Methods:Clinical data of 147 patients with postoperative locoregional recurrent ESCC receiving chemoradiotherapy in Huai'an First People's Hospital from 2016 to 2017 were retrospectively analyzed. Pectoralis muscle area (PMA) was determined using routine pre-radiotherapy CT simulation scan above the aortic arch level. Sarcopenia was defined as a cut-off value of pectoralis muscle index (PMI) (PMA/height 2) <11.55 cm 2/m 2 for males and <8.69 cm 2/m 2 for females. The incidence of toxicity, 1- and 3-year overall survival (OS) rates were statistically compared between patients with and without sarcopenia. Results:Sarcopenia was detected in 49 of 147 (33.3%) patients. The incidence of grade 3-4 toxicities in sarcopenic patients was significantly higher compared to that in their counterparts without sarcopenia (40.8% vs. 18.4%, P=0.005). In addition, patients with sarcopenia had significantly worse 1-year (61.2% vs. 82.7%) and 3-year OS rates (10.2% vs. 28.6%) than those without sarcopenia (both , P<0.001). Multivariate analysis showed that sarcopenia was an independent prognostic factor for poor OS ( P<0.001). Conclusion:PMI based on CT simulation scan has prognostic value in postoperative locoregional recurrent ESCC patients treated with chemoradiotherapy, which probably serves as a novel diagnostic tool for sarcopenia.
ABSTRACT
SUMMARY: The anatomical variations of the pectoralis major muscle (PMM) and latissimus dorsi muscle (LDM) range from agenesis to the presence of supernumerary fascicles with a variety of insertions and relationships with the muscles, fascia, vessels, nerves and skeletal components of the shoulder girdle and the axilla. Many of these variations are clinically irrelevant, but extremely interesting and revealing from the perspective of comparative anatomy, ontogeny, and phylogeny. In this report, we present two different supernumerary muscles in the chest of one adult male body, identified during dissection practice of undergraduate medical students at Universidad Surcolombiana. These supernumerary fascicles in the axillary region were caudal to the lower edge of the PMM on the right side of the chest, and in contact with the anterior edge of the LDM on the left side of the chest; each fascicle was inserted in the ipsilateral coracoid process. These observations are congruent with the pectoralis quartus muscle and an incomplete and superficial axillary arch, respectively.
RESUMEN: Las variaciones anatómicas del músculo pectoral mayor (MPM) y del músculo latísimo del dorso (MLD) van desde la agenesia hasta la presencia de fascículos supernumerarios con una variedad de inserciones y relaciones con los músculos, fascias, vasos, nervios y componentes esqueléticos de la cintura escapular y la axila. Clínicamente, muchas de las variaciones son irrelevantes, pero extremadamente interesantes y reveladoras desde la perspectiva de la anatomía comparada, la ontogenia y la filogenia. En este estudio, presentamos dos músculos supernumerarios diferentes en la pared torácica de un hombre adulto, identificados durante la práctica de disección de estudiantes de medicina de la Universidad Surcolombiana. Estos fascículos supernumerarios en la región axilar estaban caudales al margen inferior del MPM en el lado derecho del tórax y en contacto con el margen anterior del MLD en el lado izquierdo del tórax; cada fascículo se insertaba en el proceso coracoides ipsilateral. Estas observaciones son congruentes con el músculo pectoral cuarto y un arco axilar incompleto y superficial, respectivamente.

Abstract Objective To evaluate the electrophysiological activity of the injured pectoralis major (PM) muscle of operated patients who perform weightlifting, more specifically bench press exercises, especially the activity of the clavicular and sternocostal portions of the PM. Methods All athletes in study I (10 patients) had unilateral complete ruptures during bench press exercises and a history of use of anabolic steroids, an association that is described in up to 86.7% of PM tendon ruptures. The control group included 10 men without PM tendon injury who did not perform bench press exercises. Description of the cross-sectional design. The p-values were obtained by multiple comparisons with Bonferroni correction. Results In the comparison between the control (C) group and the weightlifters during the postoperative period (POS), we found no evidence of differences in any measurements obtained in the clavicular and sternocostal portions of the PM muscle: clavicular average level (p = 0.847); clavicular standard deviation (SD) (p = 0.777); clavicular area (p = 0.933); clavicular median (p = 0.972); sternocostal average level (p = 0.633); sternocostal SD (p = 0.602); sternocostal area (p = 0.931); and sternocostal median (p = 0.633). Conclusion In the present study, the electromyographic activity of the PM muscle in weightlifters (bench press exercise) who underwent surgery was within the normal parameters for the clavicular and sternocostal portions studied.

@#OBJECTIVE: It is common to get lost during a comminuted proximal humerus surgery, and the pectoralis major insertion is always a constant. Therefore, this study aimed to do a cadaveric study on the Filipino population to assess the distance from the pectoralis major tendon to the top of the humeral head (PMT) as a reference during proximal humerus surgery. METHODS: This study dissected the shoulders of cadavers. The distance from the pectoralis major tendon insertion to the top of the humeral head (PMT) was measured using a caliper. This PMT distance was also correlated to the cadaver's height and sex. RESULTS: This study dissected 110 shoulders (55 cadavers | 24 females, 31 males). The median PMT was 5.40 cm for males and 4.90 cm for females, with a combined value of 5.40 cm overall. There was a direct and moderate correlation between the PMT with overall height. Height and PMT of both the left and right shoulder were significantly longer among males compared to females. The study showed that for every centimeter increase in the height of males, there was a corresponding 0.02 cm increase in the PMT, adding the constant factor of 1.83. A corresponding 0.04 cm increase in the PMT for females added the constant factor of -0.81. CONCLUSION; The pectoralis major tendon insertion is a consistent landmark that can accurately restore humeral length when reconstructing complex proximal humerus fractures where landmarks are otherwise lost because of comminution.

Objective:To investigate effects of implantation of pectoralis major fascia combined with serratus anterior fatty fascia flap prosthesis on breast reconstruction after early breast cancer surgery.Methods:A total of 62 patients with early breast cancer undergoing breast reconstruction in Dongguan People's Hospital of Guangdong Province from July 2017 to December 2019 were selected and randomly divided into two groups, 31 cases in each group. The control group was treated with pectoralis major fascia covering prosthesis for breast reconstruction, and the observation group was treated with pectoralis major fascia combined with serratus anterior fatty fascia flap covering prosthesis for breast reconstruction. The clinical data of the two groups were recorded, the postoperative aesthetic appearance of breast was evaluated. According to the function assessment of cancer therapy-breast cancer (FACT-B) was used to evaluate the score of quality of life before and after operation, and postoperative complications were also observed.Results:In the control group and the observation group, the intraoperative blood loss was (82.61±12.38) ml, (88.76±13.57) ml, respectively; and drainage tube extubation time was (3.51±0.62) d and (3.64±0.58) d, respectively; there was no statistically significant difference between the two groups ( t value was 1.864, 0.853, respectively, all P > 0.05). The operation time of the observation group was longer than that of the control group [(2.59±0.29) h vs. (1.72±0.32) h, t = 11.217, P < 0.001]. The amount of drainage of the control group was higher than that of the observation group [(215.45±47.69) ml vs. (151.36±31.67) ml, t = 6.233, P < 0.001]; the length of hospital stay of the control group was longer than that of the observation group [(14.51±2.32) d vs. (10.79±1.86) d, t = 6.965, P < 0.001]. The excellent and good rate of postoperative breast appearance of the observation group was higher than that of the control group [96.77% (30/31) vs. 74.19% (23/31), χ 2adjusted=4.679, P = 0.031]. There were no statistical differences in all items including health, emotion, function, society/family and other conditions scores of FACT-B and total scores in both groups before the operation (all P > 0.05); all items scores and total scores of both groups after the operation were higher than those before the operation (all P < 0.001), and the sores after the operation of the observation group were higher than those of the control group (all P < 0.001). The total incidence of postoperative complications was 6.45% (2/31) of the observation group, 22.58% (7/31) of the control group, and the difference was not statistically significant (χ 2adjusted=2.080, P = 0.149). Conclusion:Breast reconstruction with implantation of pectoralis major fascia combined with serratus anterior fatty fascia flap prosthesis after early breast cancer surgery can shorten the postoperative hospital stay, improve the aesthetic appearance of breast, improve the long-term quality of life, and has a high safety.
ABSTRACT
Objective:To analysis the effect of two methods of transposition of pectoralis major in different degrees deep sternal wound infection(DSWI) after undergoing cardiac surgery.Methods:128 patients with DSWI after cardiac surgery were treated, 72 were mild, and 56 were severe. 66 cases of pectoralis major muscle flap docking method(medial muscle flap docking group) and 62 cases of lateral pectoralis major muscle flap turnover method(lateral muscle flap turnover group) were implemented respectively. Drainage tube indwelling time, reoperation rate, incidence of lung infection, long-term thoracic stability and other aspects were observed to compared the treatment effect.Results:In the mild patients, the medial muscle flap docking group and the lateral muscle flap turnover group were compared( P<0.05). The postoperative hospital stay [(14.2±4.7)days vs.(17.1±3.9)days], drainage tube retention time[(6.2±1.7)h vs.(9.1±2.9)h], and reoperation rate(2.4% vs. 6.7%), the incidence of lung infection(14.3% vs. 23.3%), long-term thoracic stability[73.8%(31/42)vs.43.3%(13/30)]. In the severe patients, the medial muscle flap docking group and the lateral muscle flap turnover group were compared. The postoperative hospital stay[(24.2±7.2)days vs.(20.1±3.5)days], drainage tube retention time[(20.2±6.6)h vs.(13.2±3.1)h], reoperation rate(20.8% vs.12.5%), incidence of pulmonary infection(41.7% vs. 31.3%), long-term thoracic stability[25.0%(6/24)vs.68.8%(22/32)]. The differences of the indicators in each group were significant , P<0.05. In the mild group, each index of the pectoralis major medial muscle flap docking method was superior to the lateral muscle flap turnover method, but the treatment results of the two methods in the severe group were opposite. Conclusion:Patients with mild deep DSWI treated with medial pectoralis major muscle flap docking and suture have less hospital stay, less reoperation rate, less complications and better treatment effect than reverse lateral pectoralis major muscle flap turnover. But the two treatments in the severe DSWI have the opposite effect.

ABSTRACT
Background: Frozen shoulder is defined as the painful and disabling condition with unknown etiology. It has a limited shoulder range of motion due to decreased capsular flexibility and altered muscle function. Assessment on the frozen shoulder is needed, and it is vital to know the alteration in scapular muscles in the shoulder range of motion during arm elevation. The intention of conducting this study is to reach conclusions of tightness of a muscle in the upper trapezius, pectoralis minor muscle, and frozen shoulder levator scapulae showing limited ranges. Methods: In this cross-sectional observational study, 50 subjects of age 30 and above were assessed for muscle length in the frozen shoulder and unaffected shoulder. Subjects with shoulder pain with frozen shoulder stage 2 and above are allotted into the affected shoulder, and unaffected shoulder; both groups were assessed. The following parameters were measured: ROM of the shoulder, SPADI ratings, short pectoral thickness, levator scapulae length, and upper trapezium muscle length. Results: Decreased shoulder flexion, extension, abduction, and limited rotations were the problems associated with frozen shoulder. Pearson correlation coefficient for PMI and LSI shows Positive Correlation r = 40.6% on the affected side. Pearson correlation for PMI and UTI shows Positive Correlation r = 13.4%. Pearson Correlation for LSI and UTI shows Positive Correlation r= 28.1% on the affected side. Conclusion: There was a correlation between upper trapezius, levator scapulae, and pectoralis minor muscle length. Most of the affected side shoulder showed the tightness in the pectoralis minor muscle.
ABSTRACT
Abstract Introduction: Pharyngocutaneous fistula is the most significant complication after salvage total laryngectomy in patients who have received previous treatment with radiotherapy with or without chemotherapy. Objective: Our purpose is to review the fistula rate in radiated patients undergoing salvage total laryngectomy, to determine if the use of pectoralis major flap interposition reduces the incidence and duration of fistula and to examine other risk factors. Methods: We made a retrospective review of patients undergoing salvage total laryngectomy for exclusively larynx cancer after failure of primary curative radiotherapy between 2000 and 2017. General data from patients, risk factors and other complications were analyzed. Results: We identified 27 patients whose mean age was 66.4 years, mainly male (92.5%). The primary closure group without pectoralis major flap included 14 patients, and the group with pectoralis major flap closure included 13 patients. Pharyngocutaneous fistula was present in 15 patients (55.5%). Global pharyngocutaneous fistula rate was higher in the group of patients without pectoralis major flap comparing with those were the flap was interposed (78.6% versus 30.8%, p = 0.047). Also the pharyngocutaneous fistulas which need to be repaired with surgery (64.3% versus 7.7%, p = 0.03) and large pharyngostomes (64.3% versus 0%, p = 0.0004) were present in a higher rate in the group closed primary without pectoralis major flap. We did not find other risk factors with statistical significance. Oral diet initiation (84 days versus 21.5 days, p = 0.039) and the duration of hospitalization (98.3 days versus 27.2 days, p = 0.0041) were much lower in patients with a preventive pectoralis major flap. Two patients died as a consequence of complications of large pharyngostomes. Conclusions: Prophylactic pectoralis major flap reduced the incidence, severity and duration of fistula and should be considered during salvage total laryngectomy.
Resumo Introdução: A fístula faringocutânea é a complicação mais significativa após laringectomia total de resgate em pacientes que receberam tratamento prévio com radioterapia com ou sem quimioterapia. Objetivo: Revisar a taxa de fístula em pacientes irradiados submetidos a laringectomia total de resgate, para determinar se o uso de interposição de retalho do peitoral maior reduz a incidência e a duração da fístula e examinar outros fatores de risco. Método: Fizemos uma revisão retrospectiva de pacientes submetidos à laringectomia total de resgate para câncer exclusivamente laríngeo após falha da radioterapia curativa primária entre 2000 e 2017. Dados gerais dos pacientes, fatores de risco e outras complicações foram analisados. Resultados: Foram identificados 27 pacientes com média de 66,4 anos, principalmente do sexo masculino (92,5%). O grupo de fechamento primário sem retalho de peitoral maior incluiu 14 pacientes e o grupo de fechamento com retalho de peitoral maior incluiu 13 pacientes. Fístula faringocutânea esteve presente em 15 pacientes (55,5%). A taxa global de fístula faringocutânea foi maior no grupo de pacientes sem retalho de peitoral maior em comparação com aqueles que receberam o retalho (78,6% vs. 30,8%, p = 0,047). Além disso, as fístulas faringocutâneas que precisaram ser reparadas através de cirurgia (64,3% vs. 7,7%, p = 0,03) e grandes faringostomias (64,3% vs. 0%, p = 0,0004) apresentaram uma taxa mais alta no grupo fechado primariamente sem retalho do peitoral maior. Não encontramos outros fatores de risco com significância estatística. O início da dieta oral (84 dias vs. 21,5 dias, p = 0,039) e a duração da internação (98,3 dias vs. 27,2 dias, p = 0,0041) foram muito menores nos pacientes com uso preventivo do retalho do peitoral maior. Dois pacientes morreram em consequência de complicações de grandes faringostomias. Conclusões: O uso profilático do retalho do peitoral maior reduziu a incidência, a gravidade e a duração da fístula e deve ser considerado durante a laringectomia total de resgate.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is a well-recognized public health problem throughout theworld. The evolution of new genetically distinct community-acquired and livestock-acquired MRSA and extended resistance toother non-β-lactams including vancomycin has only amplified the crisis. This paper presents data on the prevalence of MRSAand resistance pattern to other antibiotics on the selected specimen from burn patients.Materials and Methods: This is a prospective study conducted in the burn unit of Shyam Shah Medical College and SanjayGandhi Memorial Hospital, Rewa (M.P.), from June 2018 to May 2019, where all patients with flame and scald burns wereincluded in the study who had up to a second degree or partial-thickness burns.Results: A total of 558 patients were admitted in the burn unit throu`ghout the year, the age ranged from 2 months to 85 years.About 56.10% were females and 43.90% were males. Pseudomonas aeruginosa (37.5%) was the most common isolatefollowed by S. aureus (18.75%). The prevalence of MRSA was 57.14% but all the MRSA isolates showed 100% sensitivity tovancomycin and linezolid closely followed by piperacillin and tazobactam combination. The prevalence of methicillin resistanceoverall among S. aureus and Staphylococcus epidermidis was found to be 51.72%.Conclusion: MRSA is prevalent among the burn wounds but is 100% sensitive to vancomycin and linezolid. To ensure earlyand appropriate therapy, routine microbiological surveillance and a regular update of their antimicrobial susceptibility patterncould help in the prevention of development of multidrug resistance.
