ABSTRACT

Introdução: os cistos radiculares são as lesões císticas mais comuns nos maxilares. Eles surgem dos Restos Epiteliais de Malassez, presos no ligamento periodontal e podem ser ativados por um processo inflamatório na região pulpar. Geralmente são descobertos em exames radiográficos de rotina, apresentando-se como uma imagem radiolúcida, bem delimitada, envolvendo o periápice de um ou mais dentes. Objetivo: apresentar o tratamento de um extenso cisto radicular, em região de maxila, com acompanhamento de 18 meses. Relato do caso: Paciente do sexo feminino, 49 anos, foi encaminhada para avaliação e tratamento na Clínica Odontológica da Faculdade Sete Lagoas (FACSETE), apresentando lesão extensa em região maxilar anterior direita ao exame radiográfico. Ao exame clínico, observou-se leve assimetria facial e ausência de sintomas dolorosos. Tomografia computadorizada, punção aspirativa e biópsia incisional foram utilizadas para se chegar ao diagnóstico compatível com cisto radicular. Optou-se por uma técnica conservadora, em que foi realizada a descompressão da lesão. Após 05 meses de tratamento, um novo procedimento cirúrgico foi realizado para enuclear o restante da patologia. Conclusão: a descompressão, com utilização de cânula, é um tratamento auxiliar fácil, conservador, eficaz e reduz a morbidade causada por diferentes cistos odontogênicos(AU)


Introduction: root cysts are the most common cystic lesions in the jaw. They arise from the Epithelial Remains of Malassez, trapped in the periodontal ligament and can be activated by an inflammatory process in the pulp region. They are usually discovered in routine radiographic examinations, presenting as a well-defined radiolucent image involving the periapex of one or more teeth. Objective: to present the treatment of an extensive root cyst, in the maxillary region, with a follow-up of 18 months. Case report: A 49-year-old female patient was referred for evaluation and treatment at the Dental Clinic of Faculdade Sete Lagoas (FACSETE), with an extensive lesion in the right anterior maxillary region on radiographic examination. On clinical examination, mild facial asymmetry and absence of painful symptoms were observed. Computed tomography, aspiration puncture and incisional biopsy were used to reach a diagnosis compatible with radicular cyst. We opted for a conservative technique, in which the lesion was decompressed. After 05 months of treatment, a new surgical procedure was performed to enucleate the rest of the pathology. Conclusion: decompression, using a cannula, is an easy, conservative, effective auxiliary treatment and reduces the morbidity caused by different odontogenic cysts.

ABSTRACT

La neuralgia del trigémino es un trastorno neuropático paroxístico que afecta a una o varias de las ramas sensoriales del nervio trigémino cuya etiología es variada, la más aceptada es por compresiones vasculares a nivel del ángulo ponto cerebeloso que generan conflicto de espacio. Dentro de las posibilidades de tratamiento, la descompresión microvascular permite la cura fisiopatológica de la neuralgia del trigémino, teniendo resultados satisfactorios a corto/largo plazo, y bastantes ventajas en comparación a otras técnicas de mínima invasión. Se presenta el caso de una paciente con tratamiento médico máximo no efectivo, a la cual se realizó descompresión microvascular evidenciando conflicto arterial y venoso con el nervio.


Trigeminal neuralgia is a paroxysmal neuropathic disorder that affects one or more of the sensory branches of the trigeminal nerve, the etiology of which is varied, the most accepted being due to vascular compressions at the level of the brainstem that generate conflict of space. Within the treatment possibilities, microvascular decompression allows the pathophysiological cure of trigeminal neuralgia, having satisfactory results in the short / long term, and many advantages compared to other minimally invasive techniques. We present the case of a patient with maximum ineffective medical treatment, who underwent microvascular decompression, showing arterial and venous conflict with the nerve.

ABSTRACT

ABSTRACT Objective: To verify the effectiveness of indirect decompression after lateral access fusion in patients with high pelvic incidence. Methods: A retrospective, non-comparative, non-randomized analysis of 22 patients with high pelvic incidence who underwent lateral access fusion, 11 of whom were male and 11 female, with a mean age of 63 years (52-74), was conducted. Magnetic resonance exams were performed within one year after surgery. The cross-sectional area of the thecal sac, anterior and posterior disc heights, and bilateral foramen heights, measured pre- and postoperatively in axial and sagittal magnetic resonance images, were analyzed. The sagittal alignment parameters were measured using simple radiographs. The clinical results were evaluated using the ODI and VAS (back and lower limbs) questionnaires. Results: In all cases, the technique was performed successfully without neural complications. The mean cross-sectional area increased from 126.5 mm preoperatively to 174.3 mm postoperatively. The mean anterior disc height increased from 9.4 mm preoperatively to 12.8 mm postoperatively, while the posterior disc height increased from 6.3 mm preoperatively to 8.1 mm postoperatively. The mean height of the right foramen increased from 157.3 mm in the preoperative period to 171.2 mm in the postoperative period and that of the left foramen increased from 139.3 mm in the preoperative to 158.9 mm in the postoperative. Conclusions: This technique is capable of correcting misalignment in spinal deformity, achieving fusion and promoting the decompression of neural elements. Level of evidence III; Retrospective study.

ABSTRACT

Abstract Degenerative lumbar spinal stenosis is the most frequent cause of low back pain and/or sciatica in the elderly patient. Epidemiology, pathophysiology, clinical manifestations and testing are reviewed in a wide current bibliographic investigation. The importance of the relationship between clinical presentation and imaging study, especially magnetic resonance imaging (MRI), is emphasized. Prior to treatment indication, it is necessary to identify the precise location of pain, as well as the differential diagnosis between neurological and vascular lameness. Conservative treatment combining medications with various physical therapy techniques solves the problem in most cases, while therapeutic testing with injections, whether epidural, foraminal or facetary, is performed when pain does not subside with conservative treatment and before surgery is indicated. Injections usually perform better results in relieving sciatica symptoms and less in neurological lameness. Equine tail and/or root decompression associated or not with fusion is the gold standard when surgical intervention is required. Fusion after decompression is necessary in cases with segmental instability, such as degenerative spondylolisthesis. When canal stenosis occurs at multiple levels and is accompanied by axis deviation, whether coronal and/or sagittal, correction of axis deviations should be performed in addition to decompression and fusion, especially of the sagittal axis, in which a lumbar lordosis correction is required with techniques that correct the rectified lordosis to values close to the pelvic incidence.


Resumo A estenose degenerativa do canal vertebral lombar é a causa mais frequente de dor lombar e/ou ciática no paciente idoso; sua epidemiologia, fisiopatogenia, manifestações e testes clínicos são revistos em ampla investigação bibliográfica atual. A importância da relação entre a clínica e o estudo por imagens, principalmente a ressonância magnética (RM), é ressaltada. Antes da indicação do tratamento, é necessário identificar a localização precisa da dor, bem como o diagnóstico diferencial entre a claudicação neurogênica e a vascular. O tratamento conservador associando medicações com as diversas técnicas fisioterápicas resolve o problema na maioria dos casos, já o teste terapêutico com os bloqueios, seja epidural, foraminal ou facetário, é realizado quando as dores não cedem com o tratamento conservador e antes da indicação da cirurgia. Os bloqueios costumam dar melhores resultados no alívio dos sintomas de ciatalgia e menos no quadro de claudicação neurogênica. A descompressão da cauda equina e/ou radicular associada ou não à artrodese é o padrão ouro quando a intervenção cirúrgica é necessária. A artrodese após a descompressão é necessária nos casos com instabilidade segmentar, como na espondilolistese degenerativa. Quando a estenose de canal acontece em múltiplos níveis e vem acompanhada de desvio de eixo, seja coronal e/ou sagital, deve ser realizada, além das descompressões e artrodese, a correção dos desvios de eixo, principalmente o eixo sagital, quando a correção da lordose lombar se impõe com técnicas que corrigem a lordose retificada para valores próximos à incidência pélvica.

ABSTRACT

Resumen El tratamiento actual para la obstrucción biliar maligna es la derivación biliar no quirúrgica con propósito paliativo. La cirugía tiene indicaciones específicas en pacientes con patología maligna con propósito curativo. Sin embargo, la obstrucción duodenal y del conducto biliar intra o extrahepático no dilatado hace que esta cirugía y el procedimiento endoscópico guiado por ultrasonografía endoscópica (USE) sean difíciles de realizar. Presentamos nuestra experiencia con el primer caso en Colombia, un país latinoamericano del tercer mundo. Consistió en una colecistogastrostomía guiada por USE, a partir de la utilización de una endoprótesis luminal (Lumen-apposing metal stents, LAMS) (HOT AXIOS stent, Xlumena Inc.; Mountain View, CA, Estados Unidos) de 15 mm × 10 mm, en un paciente masculino con cáncer pancreático inoperable e invasión duodenal con conducto colédoco dilatado. La colecistogastrostomía guiada por USE podría ser considerada como una opción de más importancia para la descompresión biliar que el drenaje percutáneo, ya que es superior en términos de viabilidad técnica, seguridad y eficacia en casos específicos de estenosis ampular e invasión duodenal. Además, puede ser realizada en países del tercer mundo, cuando se cuenta con el entrenamiento y los instrumentos adecuados. La endoprótesis metálica totalmente recubierta, aplicada a luz (HOT AXIOS stent, Xlumena Inc.; Mountain View, CA, Estados Unidos), es ideal para la colecistogastrostomía guiada por USE, a fin de minimizar complicaciones como fugas biliares. Se necesitan estudios comparativos adicionales para validar los beneficios de esta técnica.


Abstract The current treatment of malignant biliary obstruction is non-surgical biliary diversion with palliative intent. The surgery having specific indications in patients with malignant pathology with curative intent. However, duodenal obstruction and non-dilated intra- or extrahepatic bile duct make these surgical and endoscopic procedures guided by EUS difficult. We present our experience with the first case in Colombia, a third-world country in Latin America, of a cholecystogastrostomy guided by endoscopic ultrasound (EUS) in a patient with unresectable pancreatic cancer and duodenal invasion with dilated common bile duct using a luminal stent (LAMS) (HOT AXIOS stent, Xlumena Inc.; Mountain View, CA, USA) 15 mm × 10 mm. EUS-guided cholecystogastrostomy should be considered as an option for biliary decompression of greater importance than percutaneous drainage since it is superior in terms of technical feasibility, safety and efficacy in specific cases of ampullary stenosis and duodenal invasion. In addition, it can be done in third world countries when it has the appropriate training and implements. The fully covered metal stent applied to light (HOT AXIOS stent, Xlumena Inc.; Mountain View, CA, USA) is ideal for EUS guided cholecystogastrostomy to minimize complications such as bile leakage. Additional comparative studies are needed to validate the benefits of this technique.

ABSTRACT

Introdução: O objetivo do trabalho é relatar um caso de ceratocisto associado à impactação dentária, o qual foi tratado com descompressão, seguido de enucleação da lesão e utilização de solução de Carnoy. Relato de caso: Paciente do sexo masculino, 14 anos, encaminhado para avaliação de lesão encontrada após exame imaginológico de rotina. O mesmo demonstrou extensa lesão radiolúcida localizada na região de ângulo e ramo da mandíbula, com presença do elemento 48 intralesional próximo a basilar. Foi realizado biópsia incisional e instalação de dispositivo de descompressão no mesmo tempo cirúrgico, o qual o resultado histopatológico foi de ceratocisto. Após 6 meses com o dispositivo, observou-se diminuição da lesão e melhora no posicionamento do dente incluso. Frente a boa resposta à descompressão, decidiu-se pela enucleação total da lesão, exodontia dos dentes 47 e 48, curetagem rigorosa e tereapia adjuvante com aplicação da solução de Carnoy. O paciente evoluiu bem, neoformação óssea na área operada e encontra-se em acompanhamento há 6 meses, sem sinais de recidiva. Considerações finais: O uso da descompressão cirúrgica em lesões císticas mandibulares minimiza os danos as estruturas circunvizinhas, riscos de fratura patológica e lesão nervosa. Em função das altas taxas de recidiva, a terapia adjuvante após a enucleção é imprescindível para essa lesão, sendo a aplicação da solução de Carnoy uma das técnicas com melhores resultados. Dessa forma, para aumentar a taxa de sucesso e minimizar as sequelas, o planejamento cirúrgico dos ceratocistos mandibulares extensos deve ser feito de forma criteriosa e cuidadosa... (AU)


Introduction: The objective of this study is to report a case of keratocyst associated with dental impaction, which was treated with decompression, followed by enucleation lesion and Carnoy solution. Case report: Male patient, 14 years old, referred for evaluation of lesion found after routine imaging. He showed extensive radiolucent lesion located in the region of the angle and branch of the mandible, with the presence of the intralesional element 48 near the basilar. An incisional biopsy was performed and a decompression device was installed during surgical time and the histopathological result was keratocyst. After 6 months of observation a reduction of the lesion and improvement in the positioning of the tooth even were noticed. Given the good response to decompression, it was decided to complete the enucleation of the lesion, extraction of teeth 47 and 48, rigorous curettage and adjuvant therapy with Carnoy's solution. Followed up for 6 months, patient evolved well creating a new bone formation in the operated area with no signs of relapse. Final considerations: The use of surgical decompression in cystic mandibular lesions minimizes damage to surrounding structures, pathological fracture risks, and nerve damage. Because of the high rates of recurrence, keratocysts require adjuvant therapy after enucleation and Carnoy's solution is one of the best performing techniques. Thus, to increase success rate and minimize sequelae, the surgical planning of extensive mandibular keratocysts should be done carefully and judiciously... (AU)

ABSTRACT

Introdução: O ameloblastoma é uma neoplasia benigna, localmente invasiva, originada do epitélio odontogênico que ainda não possui sua etiologia esclarecida. Este tumor pode ser identificado radiograficamente como unicístico ou multicístico e geralmente, está relacionado com um dente incluso. O tratamento desta patologia do complexo maxilofacial que acomete tanto a maxila quanto a mandíbula, é baseado no diagnóstico clínico, imagens (raios x (RX), tomografia computadorizada (TC) e histopatológico. O objetivo deste trabalho é descrever e avaliar através de tomografia computadorizada (TC), o tamanho do tumor durante o período em que foi submetido à descompressão, para que as dimensões do mesmo possam ser mensuradas e comparadas em intervalos, dessa forma, comprovar a efetividade dos métodos de descompressão e marsupialização quando bem indicados.Relato de caso:No presente relato de caso, o paciente apresenta ameloblastoma unicístico de variante histológica plexiforme, conforme o exame histopatológico e está sendo tratado por meio de descompressão com a finalidade de se obter a diminuição do volume da lesão cística e consequente neoformação óssea, uma vez que a descompressão possibilita este processo. Considerações finais:O tratamento conservador pode surtir efeito tal como nesse caso em que se evidenciou a regressão do tamanho do tumor e a neoformação de estruturas ósseas antes acometidas pela patologia... (AU)


Introduction: Ameloblastoma is a benign neoplasm, locally invasive, originating from the odontogenic epithelium that still does not have a clear etiology. This tumor can be radiographically identified as unicystic or multicystic and is usually related to an included tooth. The treatment of this pathology of the maxillofacial complex that affects both the maxilla and the mandible is based on clinical diagnosis, images (x-rays (X-rays), computed tomography (CT) and histopathology. The objective of this work is to describe and evaluate using computed tomography (CT), the size of the tumor during the period in which it was subjected to decompression, so that its dimensions can be measured and compared at intervals, thus proving the effectiveness of the methods of decompression and marsupialization when well indicated. Case report: In the present case report, the patient has unicystic ameloblastoma of a plexiform histological variant, according to the histopathological examination and is being treated by means of decompression in order to obtain a decrease in the volume of the cystic lesion and consequent bone neoformation, once that decompression makes this process possible. Final considerations: The conserved treatment or it can have an effect as in this case, in which the regression of the tumor size and the new formation of bone structures that were previously affected by the pathology were evidenced...

ABSTRACT

Abstract Objective To assess the long-term outcome and perioperative morbidity in spine surgeries for lumbar degenerative disorders and, thereby, to evaluate the safety of surgery in the aging population. Methods Retrospective study of patients aged > 70 years, operated for degenerative lumbar disorders between 2011 and 2015. We evaluated patient demographic, clinical and surgical data; comorbidities, perioperative complications, pre & postoperative pain scores and Oswestry disability index (ODI) scores, patient satisfaction and overall mortality. Results A total of 103 patients (Males: Females55:48) with mean age 74.6 years (70-85yrs) were studied. 60 patients (58.2%) had decompression alone, while 43 (41.8%) had decompression & fusion. Mean hospital stay was 5.7days. Mean follow-up was 47.6months (24-73mnths). Patients reported significant improvement in backpain (Numerical pain score 7.7 vs 1.6; p < 0.001), leg pain (Numerical pain score 7.4 vs 1.7; p < 0.001), disability (ODI 82.3 vs 19.1; p < 0.001) and walking distance (p < 0.001). 76% patients were satisfied with the results at the time of final follow-up. 26 patients (25.24%) had perioperative complications which were all minor, without mortality. Most common intraoperative & postoperative complications were dural tear (6.79%) & urinary tract infection (6.79%) respectively. Conclusions With meticulous perioperative care lumbar spine surgery is safe and effective in elderly population. Patients had longer mean hospital stay in view of the gradual and comprehensive rehabilitation program. Presence of comorbidities or minor perioperative complications did not increase the overall morbidity or affect the clinical outcomes of surgery in our study.


Resumo Objetivos Avaliar o resultado no longo prazo e a morbidade perioperatória em cirurgias da coluna vertebral, devido a doenças lombares degenerativas e, assim, avaliar a segurança da cirurgia na população idosa. Métodos Estudo retrospectivo de pacientes com idade superior a 70 anos, submetidos à cirurgia em virtude de distúrbios lombares degenerativos, entre 2011 e 2015. Foram avaliados os dados demográficos, clínicos e cirúrgicos dos pacientes; comorbidades; complicações perioperatórias; escores de dor no pré e no pós-operatório; índice de incapacidade de Oswestry (ODI, na sigla em inglês); satisfação do paciente e a mortalidade geral. Resultados Foram estudados 103 pacientes (homens:mulheres, 55:48) com idade média de 74,6 anos (70 a 85 anos). 60 pacientes (58,2%) apresentaram somente descompressão, enquanto 43 (41,8%) apresentaram descompressão e fusão. O tempo médio de internação foi de 5,7 dias. O tempo médio de acompanhamento foi de 47,6 meses (24-73 meses). Os pacientes relataram melhora significativa da dor nas costas (pontuação numérica da dor 7,7 versus 1,6; p < 0,001), dor nas pernas (pontuação numérica da dor 7,4 versus 1,7; p < 0,001), incapacidade (ODI 82,3 versus 19,1; p < 0,001) e distância percorrida a pé (p < 0,001). Um total de 76% dos pacientes estavam satisfeitos com os resultados no momento do acompanhamento final. 26 pacientes (25,24%) apresentaram complicações perioperatórias, todas sem relevância e sem mortalidade. As complicações intra e pós-operatórias mais comuns foram ruptura dural (6,79%) e infecção do trato urinário (6,79%), respectivamente. Conclusões Com meticulosos cuidados perioperatórios, a cirurgia da coluna lombar é segura e eficaz na população idosa. Os pacientes tiveram um maior tempo médio de internação hospitalar, em virtude do programa de reabilitação gradual e abrangente. A presença de comorbidades ou complicações perioperatórias sem relevância, não aumentou a morbidade geral, nem afetou os resultados clínicos da cirurgia em nosso estudo.

ABSTRACT

Introducción: El hemiespasmo facial primario (HFP) se produce por la hiperexcitabilidad del nervio facial y sus núcleos de origen como consecuencia de la compresión vascular. La cirugía de descompresión neurovascular se plantea como alternativa al tratamiento médico refractario. Objetivos: Presentar nuestra experiencia respecto a esta patología. Material y métodos: Se realizó una revisión retrospectiva de pacientes operados por HPF refractarios a tratamiento médico en nuestra institución en los últimos 5 años (periodo 2014-2019). Todos fueron intervenidos vía retrosigmoidea. Se evaluaron datos demográficos, evaluación prequirúrgica y evolución postoperatoria. Resultados: Se operaron 4 pacientes bajo técnica microquirúrgica asistido por endoscopía. Edad promedio 52 años (rango 41-61) con una relación femenino masculino 3:1. El 25% (n=1) presentaba paresia facial grado 2 (HB) en el prequirúrgico. No hubo cambios en cuanto al grado de paresia facial en el postoperatorio en ningún caso. Sólo un paciente registró caída leve en la audiometría postquirúrgica. El 75% (n=3) resolvieron el HFP. Conclusión: Si bien nuestra serie es acotada a un número reducido de pacientes, la cirugía descompresiva microvascular es efectiva como alternativa al tratamiento médico refractario del HFP.


Introduction: Primary hemifacial spasm (PHS) is defined as the hyper excitability of the nerve due to the compression of the facial nerve or its nuclei, most commonly by a vascular structure. The surgical indication for microvascular decompression is resistance to pharmacological treatment or severe adverse effects. Objectives: To present our experience in the surgical treatment of this pathology with this novel technique. Materials and methods: We retrospectively reviewed all patients (n=4) with a diagnosis of PHS, who underwent endoscope-assisted microvascular decompression surgery in our institution during the last 5 years. In all the cases, we choose the retrosigmoid approach. We evaluated demographic data, preoperative evaluation, and post-operative evolution. Results: Endoscope-assisted microvascular decompression was the surgical technique in all the patients. The median age was 52 years, the female-male ratio of 3:1. Only one patient presented a grade 2 facial palsy (House-Brackmann scale) in the preoperative evaluation; there were no significant changes in the post-operative evaluation in any patient. Only one patient experienced worsening in the post-operative audiometric follow-up. The 75% (n=3) of the patients solved the HFP after the surgical treatment. Conclusion: By taking into account our experience in this small case series, we can support the concept that endoscope-assisted microvascular decompression is as effective as the open surgical treatment of the PHS.

BACKGROUND: We aimed to confirm the long-term effect of patellar nonresurfacing (patellar decompression) in preventing anterior knee pain after total knee arthroplasty (TKA) and to investigate the possible complications.METHODS: Among patients who underwent primary TKA after being diagnosed as having advanced osteoarthritis (Kellgren-Lawrence grade 4) at our institution from January 2004 to December 2010, 121 patients who were followed up for more than 7 years were included in this study. Patients who underwent TKA with and without patellar decompression were classified as the study group and control group, respectively. A clinical knee rating score was used to compare the postoperative clinical outcomes between groups. To identify complications after patellar decompression, simple radiographs (weight-bearing anteroposterior and lateral views, patella in 30° and 45° axial views, and whole scanogram) were taken during follow-up.RESULTS: There were no complications such as patellar fracture, osteonecrosis, and subluxation. At 2 years after surgery, the prevalence of anterior knee pain was 12.7% and 18.0% in the study group and control group, respectively (p = 0.42), and the number of patients with patellofemoral osteoarthritis grade II or over was lower in the study group (p = 0.03). At 7 years after surgery, the prevalence of anterior knee pain was 18.3% and 24.0% in the study group and control group, respectively (p = 0.45), and there was no statistically significant intergroup difference in the number of patients with patellofemoral osteoarthritis grade II or over (p = 0.11).CONCLUSIONS: Patellar nonresurfacing TKA reduces anterior knee pain in the early postoperative period. The procedure can be considered a relatively safe option with fewer complications; however, its effectiveness appears to decrease over time.

ABSTRACT

OBJECTIVE@#To explore the effect of anterolateral spinal canal decompression combined with short segment screw fixation with posterior approach for severe thoracolumbar burst fractures with spinal cord injury.@*METHODS@#From January 2016 to June 2018, 16 patients with severe thoracolumbar burst fractures (more than 50% of ratio of spinal canal encroachment, reverse fragment at the posterior edge of the vertebral body) with spinal cord injury were retrospectively analyzed, including 10 males and 6 females, ranging in age from 19 to 57 years old. Causes of injury:8 cases of fall injury, 6 cases of traffic accident injury and 2 cases of other injuries. Fracture site:T@*RESULTS@#All 16 patients were followed up, and the average follow up time was (15.9±5.4) months. The average operation time was (234±41) minutes and the average amount of bleeding was (431±93) ml. The loss of anterior height of injured vertebrae was (52.25±10.10)% before operation, (8.93± 3.61)% at 3 days after operation, and (9.25±2.88)% at the latest follow up. The results of 3 days after operation and the latest follow up were better than that before operation, and there was no significant differencesbetween results at the latest follow up and 3 days after operation (@*CONCLUSION@#For severe thoracolumbar burst fracture and spinal cord injury, with more than 50% of ratio of spinal canal encroachment and reverse fragment at the posterior edge of the vertebral body, the anterolateral spinal canal decompression combined with short segment screw fixation with posterior approach has the characteristics of accurate reduction, complete decompression and firm fixation, and the clinical effect is satisfactory.

ABSTRACT

ABSTRACT Objective: To conduct a multicenter analysis of the effectiveness of surgical tactics for treating patients with symptomatic tandem stenosis of the cervical and lumbar spine, based on a differentiated clinical-instrumental algorithm. Methods: The study included 97 patients with symptomatic tandem stenosis of the cervical and lumbar spine. The patients were allocated into 2 groups. The main prospective follow-up group (Group I) consisted of patients (n=46) who had undergone staged decompression/stabilization surgery according to the surgical tactics developed based on the differential clinical-instrumental algorithm. The clinical comparison group (Group II) (n=51) consisted of retrospectively recruited patients who, depending on the prevailing clinical condition, underwent primary surgery at the cervical level (29 cases) or at the lumbar level (22 cases). Results: The comparative analysis in Group I revealed significantly better parameters in the clinical and instrumental data. The total rates of postoperative surgical complications in the cervical and lumbar spine were 15% in Group I and 68% in Group II (p=0.0014). Conclusion: The multicenter analysis of the clinical-instrumental algorithm based on differential application of decompression/stabilization techniques enabled more rational and radical surgery, with less adverse outcomes, leading to earlier start of rehabilitation in the prospective group of patients (Group I), and an objective improvement in long-term clinical and functional outcomes.

ABSTRACT

Introducción: Existen múltiples técnicas para la descompresión medular en la columna torácica, cada una con sus ventajas y desventajas y con distintos requerimientos de destre-zas quirúrgicas. Se han desarrollado técnicas mínimamente invasiva que disminuyen las tasas de morbilidad, con buenos resultados funcionales. Objetivo: El objetivo del trabajo es describir la técnica quirúrgica y presentar los resulta-dos iniciales en 2 años consecutivos de trabajo. Materiales y métodos: Se evaluaron los pacientes operados en 2017 y 2018 con hernia de disco dorsal tratadas con técnica de abordaje transtorácico mínimamente invasivo. Descri-biendo detalladamente la técnica quirúrgica, la evolución y las complicaciones a corto y mediano plazo. Resultado: Se evaluaron 8 pacientes. El seguimiento promedio fue de 9 meses (3 ­ 26 meses) con una edad promedio de 54 años (28 ­ 66 años). Los motivos de consulta fue-ron en su mayoría dolor dorsal y diferentes grados de compromiso medular (mo-tor/sensitivo). Los niveles fueron distales a T6 y proximales a T12. Todos los pacientes mantuvieron o mejoraron su función neurológica. No se presentaron complicaciones ma-yores. Conclusiones: Si bien se trata de una serie pequeña de casos, son más que suficientes para demostrar que se puede llevar a cabo una técnica novedosa, mínimamente invasiva, utili-zando el separador con visión tubular y el microscopio que aporta luz y magnificación, permitiendo trabajar a cuatro manos cara a cara entre dos cirujanos. Presentando bajas tasas de morbimortalidad y una rápida recuperación.


Introduction: There are multiple techniques for spinal decompression in the thoracic spine, each with its advantages and disadvantages and with different requirements for sur-gical skills. Minimally invasive techniques have been developed that decrease morbidity rates, with good functional results. Objective: The objective of the study is to describe the surgical technique and present initial results in 2 consecutive years of work. Materials and methods: Patients operated in 2017 and 2018 with dorsal disc hernia treat-ed with a minimally invasive transthoracic approach technique were evaluated. Describing in detail the surgical technique and the evolution and complications in the short and medi-um term. Conclusions: Although it is a small series of cases, they are more than enough to demon-strate that a novel, minimally invasive technique can be carried out, using the tubular vi-sion separator and the microscope that provides light and magnification, allowing to work with four hands, face to face between two surgeons. Presenting low rates of morbidity and mortality and rapid recovery.

ABSTRACT

For a minimally invasive approach to access the facial nerve, we designed an extended epitympanotomy via a transmastoid approach that has proven useful in cases of traumatic facial nerve palsy and pre-cholesteatoma. To evaluate the surgical exposure through an extended epitympanotomy, six patients with traumatic facial nerve palsy were enrolled in this study. The same surgical technique was used in all patients. Patients were assessed and the degree of facial nerve paralysis was determined prior to surgery, 1-week post-operatively, and 6-months post-operatively using the House-Brackmann grading system. In all cases, surgical exposure was adequate. All patients with traumatic facial nerve palsy were male and the age range was 13 to 83 years. In all cases, the location of the facial nerve damage was limited to the area between the first and second genu. Symptoms of all the patients improved by 6 months post-operation (p=0.024). There were no complications in any of the patients. Extended epitympanotomy is useful for safe, rapid surgical exposure of the attic area, sparing the patient post-operative dimpling, skin incision complications, and lengthy exposure to anesthesia. We suggest that surgery for patients with facial nerve palsy secondary to trauma be performed using this described technique.

ABSTRACT

STUDY DESIGN: Retrospective study. OBJECTIVES: To compare surgical outcomes such as the ambulatory period and survival according to different surgical excision tactics for metastatic spine tumors (MSTs). SUMMARY OF LITERATURE REVIEW: Surgical outcomes, such as pain relief and survival, in patients with MSTs have been reported in several studies, but the effects of differences in surgical extent on the ambulatory period have rarely been reported. MATERIALS AND METHODS: Ninety-six patients with MSTs who underwent palliative (n=60) or extensive wide excision (n=36) were included. Palliative excision was defined as partial removal of the tumor as an intralesional piecemeal procedure for decompression. Extensive wide excision was defined as a surgical attempt to remove the whole tumor at the index level as completely as possible. The primary outcome was the ambulatory period following surgery. Other demographic and radiographic parameters were analyzed to identify the risk factors for loss of ambulatory ability and survival. Perioperative complications were also assessed. RESULTS: The mean postoperative ambulatory period was longer in the extensive wide excision group (average 14.8 months) than in the palliative excision group (average 11.7 months) (p=0.021). The survival rates were not significantly different between the two surgical excision groups (p=0.680). However, postoperative ambulatory status and major complications within 30 days postoperatively were significant prognostic factors for survival (p=0.003 and p=0.032, respectively). CONCLUSIONS: The extent of surgical excision affected the ambulatory period, and the complication rates were similar, regardless of surgical excision tactics. A proper surgical strategy to achieve postoperative ambulatory ability and to reduce perioperative complications would have a favorable effect on survival.

ABSTRACT

STUDY DESIGN: Case report. OBJECTIVES: To document the first known case of posterior migration of a herniated disc in a lumbar flexion-distraction injury. SUMMARY OF LITERATURE REVIEW: Lumbar disc herniation is sometimes confused with epidural hematoma, especially when the disc migrates posterior to the thecal sac. There has been no report of posterior migration of a herniated disc after a lumbar flexion-distraction injury. MATERIALS AND METHODS: A 47-year-old woman with no pertinent medical history was diagnosed with a flexion-distraction injury of the L2–L3 vertebrae after a motor vehicle accident. The patient had no neurological deficit initially. Magnetic resonance imaging (MRI) showed a space-occupying lesion with T2 hyperintensity and T1 isointensity on the dorsal side of the thecal sac at L2–L3. After posterior lumbar fixation and fusion, progressive leg weakness occurred 1 week postoperatively. RESULTS: A second operation revealed no evidence of epidural hematoma, but a sequestrated disc. Decompression and sequestrectomy were performed, and the patient's neurological status had recovered fully at 4 months postoperatively. CONCLUSIONS: This case highlights the potential for posterior migration of a herniated disc with flexion-distraction injuries of the thoracolumbar spine. Discontinuity of the posterior annulus fibrosus on MRI may aid the distinction of posterior migration of a herniated disc from epidural hematoma. Because posterior migration of a herniated disc is associated with progressive neurological deficits, surgeons must consider decompression surgery when such herniation is suspected, even in the absence of neurological symptoms.

ABSTRACT

STUDY DESIGN: Retrospective analysis OBJECTIVES: To evaluate preoperative factors related with spinal canal expansion after posterior decompression for the treatment of multilevel cervical myelopathy. SUMMARY OF LITERATURE REVIEW: Data about preoperative factors related with spinal canal expansion after posterior cervical decompression surgery are inconsistent. MATERIALS AND METHODS: We reviewed 67 patients with cervical myelopathy who underwent posterior laminectomy or laminoplasty. Radiologically, we evaluated the C2-7 Cobb angle and range of motion using X-rays from the preoperative assessment and final follow-up. Expansion of the spinal canal at 6 weeks postoperatively was evaluated using magnetic resonance imaging and compared with the preoperative values. The preoperative factors of age, sex, number of operated levels, operation method, and radiological parameters were investigated as factors potentially related to postoperative spinal canal expansion using multivariate regression and correlation analyses. The clinical outcome was analyzed by the Neck Disability Index (NDI) and Japanese Orthopaedic Association (JOA) scores. RESULTS: The postoperative spinal canal expansion was 4.76 mm in sagittal images and 4.31 mm in axial images, with higher values observed in males and cases of severe preoperative cord compression. A lordotic preoperative Cobb angle was related to postoperative spinal canal expansion and JOA score improvement, but without statistical significance. The clinical outcomes of NDI (18.3→14.8) and JOA scores (10.81→14.6) showed improvement, but were not significantly related with any preoperative factors. CONCLUSIONS: The amount of preoperative spinal canal stenosis was associated with postoperative spinal canal expansion after posterior decompression in multilevel cervical myelopathy. The preoperative Cobb angle was not related to postoperative spinal canal expansion or clinical improvement.
