RESUMO

Objective: Primary Hemifacial Spasm (PHFS) significantly impacts quality of life, necessitating effective treatment like microvascular decompression of the facial nerve. This study aims to identify prognostic factors related to surgical treatment to enhance outcomes and minimize complications. A systematic review of literature from the past five years was conducted. Methods: Following PRISMA guidelines, we systematically searched databases like PubMed, Embase, Scopus, Ovid, EBSCO, and Cochrane using keywords such as 'Hemifacial spasm,' 'Microvascular decompression,' 'Neurovascular conflict,' and 'Surgical techniques.' The search spanned January 2018 to November 2023. The 'Rayyan' program facilitated data compilation. Each author reviewed abstracts, applying inclusion criteria like systematic reviews, clinical trials, observational studies, and case series, while excluding theoretical or non-English articles. Results: Of 26 selected articles, those solely addressing PHFS treatment with botulinum toxin and lacking surgical procedure data were excluded. Thus, our analysis focused on 16 articles, including meta-analyses, systematic reviews, clinical trials, and observational studies. Discussion: Microvascular decompression at the cerebellar pontine angle is the mainstay treatment for hemifacial spasm. Despite limited statistically significant prognostic factors in the literature, overarching recommendations aim to improve outcomes, minimize complications, and prevent recurrences. Key considerations include surgeon expertise, precise techniques, thorough nerve exploration, identifying the conflict's cause, and intraoperative monitoring. Conclusions: PHFS significantly impacts patients' lives, necessitating timely surgical intervention if initial treatments fail. While statistically significant prognostic factors may be lacking, this study highlights crucial considerations for successful treatment.

RESUMO

Background: Microvascular decompression (MVD) using Teflon or Ivalon is the surgeon's preference for treating trigeminal neuralgia (Tn). Still, sometimes the prosthetic material is unavailable, or there is some recurrence of pain during the follow-up. In this case series, we report the outcome analysis for MVD using the expanded polytetrafluoroethylene (ePTFE) sleeve technique in classic Tn. Methods: We conducted a retrospective analysis of patients with Tn from January 2017 to March 2022. Classic or primary Tn was considered a direct compression by a cerebrovascular structure in the posterior fossa, detected by magnetic resonance imaging or direct surgical visualization. Pre- and postoperative Barrow Neurological Institute Pain Intensity Scale (BNI-SI) and Barrow Neurological Institute Hypoesthesia Scale (BNI-HS) were used for the clinical results assessment of the ePTFE sleeve circumferential technique. Results: There were nine patients approached with the 3/4 circumferential ePTFE sleeve technique with BNISI IV (n: 11, 58%) and BNI-SI V (n: 8, 42%). In all patients, there was a clinical improvement after the surgical treatment (P < 0.001). All patients obtained BNI-SI ≤ IIIa in an average follow-up of 11.89 (±14.137), with a slight improvement in BNI-HS (P: 0.157). In our revision, this technique has not previously been described for Tn. Conclusion: The circumferential ePTFE sleeve technique is a good option for MVD in Tn. For classic Tn, MVD could remain the first option, and this technique could be applied for multi-vessel compression.

RESUMO

Objective: The objective of the study was to analyze the application value of opioid-free anesthesia (OFA) in renal cyst decompression by laparoscopy. Method: A total of 124 patients undergoing renal cyst decompression by laparoscopy in our hospital were selected and divided into opioid anesthesia (OA) and OFA groups (n = 62). Fentanyl and remifentanil were used for anesthesia induction in the OA group, while lidocaine and dexmedetomidine were employed for anesthesia induction in the OFA group. The homeostasis indicators (cortisol [Cor], adrenocorticotropic hormone [ACTH], C-reactive protein [CRP], and interleukin-6 [IL-6]) were also compared 10 min before anesthesia (Ta), at the end of operation (Tb), and 24 h after operation (Tc). Results: At T1-T3, heart rate, mean arterial pressure, mean airway pressure, and partial pressure of end-tidal carbon dioxide were all lower in OFA group than those in OA group (p < 0.05). At Tb-Tc, the levels of Cor, ACTH, CRP, and IL-6 were all higher in both groups than those at Ta (p < 0.05), while they were lower in OFA group than those in OA group (p < 0.05). Conclusion: OFA is more beneficial to the respiratory and circulatory system and homeostasis of patients, and has higher anesthetic safety.

RESUMO

This study presents a randomized controlled crossover experiment involving 73 patients with idiopathic bilateral Carpal Tunnel Syndrome (CTS). Patients received two combined physiotherapeutic treatments: myofascial mobilization (IASTM) and stretching. Participants were divided into two groups: one started with stretching followed by IASTM, and the other with IASTM followed by stretching. Of these, 43 underwent surgery and began physical therapy 30 days post-operation, while 30 received non-surgical treatment. The therapy sessions lasted four weeks, followed by a crossover of the treatment modalities and periodic reassessments up to six months. The dataset includes experimental design, patient demographics, diagnostic data, objective muscle strength tests, subjective sensitivity tests, clinical indicators, and self-reported measures. This data can be useful for researchers looking to replicate the study or compare outcomes between clinical and surgical CTS patients.

RESUMO

INTRODUCTION: the pandemic of COVID-19 has led to clinical complications such as avascular necrosis of the femoral head (AVNFH) associated with the use of corticosteroids. The aim of the study is to report the functional and radiographic results of 13 patients with post-COVID-19 ANFH after decompression using Forage and bone marrow aspirate concentrate (BMAC). MATERIAL AND METHODS: single-center, prospective, uncontrolled clinical study. From April 2020 to September 2021, 13 patients (21 hips) with post-COVID-19 ANFH were treated. All received corticosteroids during infection (average daily dose: 480 mg). Clinical, radiographic and magnetic resonance imaging evaluations were performed; the Ficat classification was applied for the classification of AVNFH. The surgical technique used was decompression with Forage and ACMO. RESULTS: the mean age was 47 years, with a follow-up of 30.4 months. Symptoms appeared with a mean of 4.2 months after COVID-19 infection. Harris score improved from 41.2 ± 5.2 to 86.6 ± 3.4. Radiographic evaluation showed that 14.3% of the sample experienced femoral head collapse and underwent total hip arthroplasty. CONCLUSIONS: post-COVID-19 ANFH is a clinical entity with rapid progression and different degrees of severity. Decompression with Forage and ACMO seems a promising initial treatment, however, the variable response and the probability of collapse emphasize the importance of long-term follow-up and identification of patients who may require additional interventions.

INTRODUCCIÓN: la pandemia de COVID-19 ha dado lugar a complicaciones clínicas como la necrosis avascular de la cabeza femoral (NAVCF) asociada con el uso de corticoesteroides. El objetivo del estudio es reportar los resultados funcionales y radiográficos de 13 pacientes con NAVCF post-COVID-19, después de la descompresión utilizando Forage y aspirado de células de medula ósea (ACMO). MATERIAL Y MÉTODOS: estudio clínico unicéntrico, prospectivo, no controlado. Desde Abril de 2020 hasta Septiembre de 2021, se trataron 13 pacientes (21 caderas) con NAVCF post-COVID-19. Todos recibieron corticoesteroides durante la infección (dosis promedio diaria: 480 mg). Se realizaron evaluaciones clínicas, radiográficas y por resonancia magnética nuclear; se aplicó la clasificación de Ficat para la clasificación de NAVCF. La técnica quirúrgica empleada fue descompresión con Forage y ACMO. RESULTADOS: la edad promedio fue 47 años, con un seguimiento de 30.4 meses. Los síntomas aparecieron con una media de 4.2 meses después de la infección por COVID-19. La escala de Harris mejoró de 41.2 ± 5.2 a 86.6 ± 3.4. La evaluación radiográfica demostró que 14.3% de la muestra experimentó colapso de la cabeza femoral por lo que se les realizó artroplastía total de cadera. CONCLUSIONES: la NAVCF post-COVID-19 es una entidad clínica con rápida progresión y diferentes grados de severidad. La descompresión con Forage y ACMO parece un tratamiento inicial prometedor; sin embargo, la respuesta variable y la probabilidad de colapso, enfatizan la importancia de seguimiento a largo plazo e identificación de los pacientes que puedan requerir intervenciones adicionales.

RESUMO

Bispectral index with density spectral array (BIS-DSA) monitoring during hyperbaric oxygen therapy of a case with inner ear and cerebral decompression sickness is described. During the initial treatment, a particular DSA pattern was found, which resolved after four treatments. Clinical resolution of the symptoms accompanied this improvement. The particular BIS-DSA pattern described in this case is concordant with a potential hypo-perfusion of the cortex related to decompression stress. This case suggests that BIS-DSA monitoring may be an easy, cost-effective, and viable form of neuro-monitoring during hyperbaric oxygen treatment for decompression sickness.

RESUMO

El queratoquiste odontogénico constituye del 3 a 11% de los quistes odontogénicos. Se presenta desde la infancia hasta la vejez con mayor incidencia en hombres. La mandíbula está involucrada en el 60% al 80% de los casos, con una frecuencia en cuerpo y rama. Las lesiones de menor tamaño suelen ser asintomáticos, diagnosticados por examen radiográfico, no obstante, las lesiones más grandes pueden estar asociadas con dolor y aumento de volumen. Radiográficamente se observan lesiones uniloculares o multiloculares radiolúcidas de bordes nítidos, corticalizados, asociado a un diente retenido. Se presenta caso clínico de paciente género masculino de 30 años de edad, que exhibe una expresión atípica. Manifestándose como una doble lesión de queratoquistes odontogénicos independientes entre sí, localizados en rama y cuerpo mandibular derecha, tratado en el Servicio de Cirugía Maxilofacial del Hospital San José, Santiago de Chile. Se describe diagnóstico y tratamiento quirúrgico realizado. El interés clínico del caso es la presencia de dos lesiones independientes entre sí, con el mismo diagnóstico. Presentación que nos parece fundamental reportar en la literatura científica debido a su alto alcance e impacto.

The odontogenic keratocyst represents 3 to 11% of all odontogenic cysts. It occurs from childhood to old age with a higher incidence in men. The mandible is involved in 60% to 80% of cases, with a frequency in the body and ramus. Smaller lesions are usually asymptomatic and diagnosed by radiographic examination. However, larger lesions may be associated with pain and increased volume. Radiographically, radiolucent unilocular or multilocular lesions with sharp, corticalized edges are observed, associated with an impacted tooth. A clinical case of a 30-year-old male patient, who exhibits an atypical expression, is presented. A double lesion of odontogenic keratocysts independent of each other appears, located in the right mandibular ramus and body, treated in the Maxillofacial Surgery Service of the San José Hospital, Santiago de Chile. Diagnosis and surgical treatment performed are described. The clinical interest of the case is the presence of two lesions independent of each other, with the same diagnosis. It seems fundamental to us to report it in the scientific literature due to its high scope and impact.

RESUMO

This study aimed to evaluate pain assessment strategies and factors associated with outcomes after microvascular decompression for the treatment of primary trigeminal neuralgia in adults. We conducted a systematic review and meta-analysis of English, Spanish, and French literature. We searched three databases, PubMed, Ovid, and EBSCO, from 2010 to 2022 and selected studies including patients with primary trigeminal neuralgia, clear pain assessment, and pain outcomes. Population means and standard deviations were calculated. Studies that included factors associated with postoperative outcomes were included in the meta-analysis. A total of 995 studies involving 5673 patients with primary trigeminal neuralgia following microvascular decompression were included. Patients with arteries compressing the trigeminal nerve demonstrated optimal outcomes following microvascular decompression (odds ratio [OR]= 0.39; 95% confidence interval [CI] = 0.19-0.80; X2 = 46.31; Dof = 15; I2 = 68%; P = < 0.0001). Conversely, when comparing arterial vs venous compression of the trigeminal nerve (OR = 2.72; 95% CI = 1.16-6.38; X2 = 23.23; Dof = 10; I2 = 57%; P = 0.01), venous compression demonstrated poor outcomes after microvascular decompression. Additionally, when comparing single-vessel vs multiple-vessel compression (OR = 2.72; 95% CI = 1.18-6.25; X2 = 21.17; Dof = 9; I2 = 57%; P = 0.01), patients demonstrated unfavorable outcomes after microvascular decompression. This systematic review and meta-analysis evaluated factors associated with outcomes following microvascular decompression (MVD) for primary trigeminal neuralgia (PTN). Although MVD is an optimal treatment strategy for PTN, a gap exists in interpreting the results when considering the lack of evidence for most pain assessment strategies.

Objective: The Dentigerous Cyst (DTC) is the most common type of developmental odontogenic cyst and the second most frequent among all that occur in the jaws. It is a benign, radiolucent, usually unilocular lesion, prevalent in males, in the first three decades of life and with a greater occurrence in the mandible. It has slow and asymptomatic growth and its etiopathogenesis is still considered unknown. This paper aims to report two clinical cases of dentigerous cysts, the first in a 50-year-old patient and the second in an 11-year-old patient, both located in the mandible and involving molars. Case report: The method used to treat this lesion was decompression, in which a communication was created between the cyst and the oral cavity, placing a device to condition its drainage and subsequent enucleation ofthe lesion and the tooth involved. This treatment, being less invasive, promotes greater preservation of adjacent healthy stmctures and, consequently, a more favorable postoperative peñod. Conclusion: Therefore, it is of utmost importance that the professional is able to perform this type of procedure and has the knowledge to perform the technique, so that the risk of trans and postoperative complications is reduced...

RESUMO

INTRODUCTION: Urinary tract infection involves mortality rate when combined with ureteral obstruction. Lithotripsy has been contraindicated; however, it has been shown to be safe in selected situations. No specific criteria have been widely accepted to indicate which patients are suitable for definitive treatment. The objective of this study was to identify prognostic factors associated with poor outcome but also those patients whose definitive treatment can be performed. METHODS: Observational cohort study from a prospectively maintained database of septic patients defined by the Sequential Organ Failure Assessment (SOFA). Univariate analysis was used to compare prognostic factors with Δ-SOFA score <2 (group 1) and those with a Δ-SOFA ≥2 (group 2) obtained on day 3 and on admission. Different combinations of neutrophils, lymphocytes and platelets were tested as prognostic factors. Time to decompression calculated from the CT scan report to the end of surgery. RESULTS: A total of 229 patients were enrolled during 11 years. Two patients died. Time from CT scan to urinary tract decompression was higher in the Δ-SOFA≥2 (p = 0.04). Thrombocytopenia and the platelet-to-lymphocyte ratio were associated with Δ-SOFA≥2. Stones were disintegrated in 33.48% in group 1 and 48.84% in group 2. Platelet count and time to decompression were associated with a worse prognosis (p = 0.0008 and 0.0017). On receiver operator curve analysis, platelets count <105,056 and time to decompression >4.72 hours were linked to poorer outcomes. CONCLUSIONS: Personalized treatment, based on accessible biomarkers, can be achieved in most patients. Early surgical decompression was associated with better prognosis and definitive treatment can be performed in selected patients.

RESUMO

Posterior fossa tumours are one of the most common types of solid neoplasia in paediatric patients. Although impaired vision can occur at presentation, it usually stabilises or improves after decompressive surgery. However, cases of permanent and profound visual loss have been reported following successful tumour resection, despite receiving little attention from the medical community. In this paper, we present two cases of young patients who experienced severe and permanent visual loss following uncomplicated surgery for posterior fossa tumour removal. We discuss the possible mechanism involved in the visual loss and measures to prevent such a dreadful complication.

RESUMO

Classical trigeminal neuralgia (TN), caused by vascular compression of the nerve root, is a severe cause of pain with a considerable impact on a patient's quality of life. While microvascular decompression (MVD) has lower recurrence rates when compared with partial sensory rhizotomy (PSR) alone, refractoriness can still be as high as 47%. We aimed to assess the efficacy and safety profile of MVD + PSR when compared to standalone MVD for TN. We searched Medline, Embase, and Web of Science following PRISMA guidelines. Eligible studies included those with ≥ 4 patients, in English, published between January 1980 and December 2023, comparing MVD vs. MVD + PSR for TN. Endpoints were pain cure, immediate post-operative pain improvement, long-term effectiveness, long-term recurrence, and complications (facial numbness, hearing loss, and intracranial bleeding). We pooled odds ratios (OR) with 95% confidence intervals with a random-effects model. I2 was used to assess heterogeneity, and sensitivity and Baujat analysis were conducted to address high heterogeneity. Eight studies were included, comprising a total of 1,338 patients, of whom 1,011 were treated with MVD and 327 with MVD + PSR. Pain cure analysis revealed a lower likelihood of pain cure in patients treated with MVD when compared to patients treated with MVD + PSR (OR = 0.30, 95% CI: 0.13 to 0.72). Immediate postoperative pain improvement assessment revealed a lower likelihood of improvement in the MVD group when compared with the MVD + PSR group (OR = 0.31, 95% CI: 0.10 to 0.95). Facial numbness assessment revealed a lower likelihood of occurrence in MVD alone when compared to MVD + PSR (OR = 0.08, 95% CI: 0.04 to 0.15). Long-term effectiveness, long-term recurrence, hearing loss, and intracranial bleeding analyses revealed no difference between both approaches. Our meta-analysis identified that MVD + PSR was superior to MVD for pain cure and immediate postoperative pain improvement for treating TN. However, MVD + PSR demonstrated a higher likelihood of facial numbness complications. Furthermore, identified that hearing loss and intracranial bleeding complications appear comparable between the two treatments, and no difference between long-term effectiveness and recurrence.

RESUMO

OBJECTIVE: Obesity is a global epidemic affecting developing countries. The relationship between obesity and perioperative outcomes during elective lumbar spine surgery remains controversial, especially in those without morbid disease. MATERIALS AND METHODS: We retrospectively revised the medical records of patients with lumbar spine degeneration subjected to elective surgery. The data retrieved included demographic and clinical characteristics, body mass index (BMI), obesity status (BMI ≥ 30), surgical interventions, estimated blood loss (EBL), operative time, length of stay (LOS), and post-operative complications. Perioperative outcomes were compared between Grade I-II obese and non-obese individuals. RESULTS: We enrolled 53 patients, 18 with Grade I-II obesity. Their median age was 51, with no differences in gender, comorbidities, laboratory parameters, and surgical procedures received between groups. No clinically relevant differences were found between grade I-II obese and non-obese participants in EBL (300 mL vs. 250 mL, p = 0.069), operative time (3.2 h vs. 3.0 h, p = 0.037), and LOS (6 days vs. 5 days, p = 0.3). Furthermore, BMI was not associated with the incidence of significant bleeding and long stay but showed a modest correlation with operative time. CONCLUSION: Grade I-II obesity does not increase surgical complexity nor perioperative complications during open lumbar spine surgery.

OBJETIVO: La obesidad es una epidemia mundial que afecta a países subdesarrollados. Su relación con los resultados de la cirugía de columna lumbar electiva sigue siendo controvertida, especialmente en obesos sin enfermedad mórbida. MÉTODOS: Se revisaron los expedientes de pacientes con degeneración de la columna lumbar sometidos a cirugía. Los datos recuperados incluyeron características demográficas y clínicas, índice de masa corporal (IMC), estado de obesidad (IMC > 30), intervenciones quirúrgicas, sangrado estimado, tiempo operatorio, tiempo de estancia y complicaciones. Los resultados se compararon entre individuos obesos grado I-II y controles. RESULTADOS: Se incluyeron 53 pacientes, 18 con obesidad de grado I-II. La edad media fue de 51 años, sin diferencias en el sexo, las comorbilidades, los parámetros de laboratorio y los procedimientos quirúrgicos recibidos entre grupos. No se encontraron diferencias relevantes entre los participantes obesos y los no obesos en sangrado (300 vs. 250 mL, p = 0.069), tiempo operatorio (3.2 vs. 3.0 horas, p = 0.037) y estancia (6 vs. 5 días, p = 0.3). El IMC no se asoció con hemorragia y larga estancia, pero mostró una correlación modesta con el tiempo operatorio. CONCLUSIONES: La obesidad grado I-II no predispone a complicaciones durante la cirugía de columna lumbar.

RESUMO

Background: Trigeminal neuralgia (TN) is a highly disabling facial pain syndrome, historically known as the suicide disease, in which most cases can be cured with appropriate surgical treatment. Case Description: We present the case of a 43-year-old male farmer with acute, self-limiting episodes of shock-like pain on the left side of the face that started in June of 2021. He was diagnosed with TN and was treated with carbamazepine. Magnetic resonance imaging was performed, which revealed an epidermoid cyst (EC) at the prepontine cistern with an extension to the left cerebellopontine angle. The neurosurgery department at our institution was consulted, which performed surgical tumor resection and Vth cranial nerve decompression. During the resection, a neurovascular conflict (NVC) was identified at the root entry zone. After the resection around the nerve and its whole tract was completed, a microvascular decompression (MVD) was performed. Conclusion: TN secondary to EC in association with a NVC is a rare phenomenon, due to the growth pattern of the EC. TN may remit if an appropriate treatment is carried out. In cases of NVC, an MVD is required apart from an appropriate resection to achieve pain relief.

RESUMO

PURPOSE: Chiari II malformation (CM-II) is a congenital malformation of the posterior fossa associated with myelomeningocele. Of the symptomatic patients, 10-33% require surgical treatment. To this date, there is not a consensus about the best surgical technique, and whether to do duroplasty. METHODS: A literature search of the PubMed database and crossed references was performed, per PRISMA guidelines. Data regarding demographic features, extent of cervicomedullary deformity, clinical presentation, surgical techniques, and clinical outcomes were extracted. Pearson's chi-squared test was applied. The p-values under 0.05 were considered statistically significant. RESULTS: Twenty studies (N = 330) were analyzed. C3 and C4 levels represented 56.4% of the lowest tonsil displacement. The most reported symptom was dysphagia/swallowing dysfunction (53.8%). Suboccipital craniectomy (SOC) and cervical spine expansion (CSE) with duroplasty were the most reported technique. Dural augmentation was performed in 57.4% of the patients. After surgery, 59.6% observed an improvement in symptoms and quality of life, 12.5% were unchanged, and 27.8% had a worsened clinical status. The mortality rate was 2.5% during the first month after surgery, and 17.4% at the last follow-up evaluation. Patients who underwent CSE presented a better clinical outcome (p = 0.002). The SOC procedure could not be correlated with symptom improvement (p = 0.06). CONCLUSION: CM-II is associated with high morbidity and mortality. An early onset symptomatic CM-II demands intervention, which provided an improvement of outcome in most patients included in this review. The best surgical technique and the exact effect of the surgical management of CM-II on mortality are not yet clear.

RESUMO

OBJECTIVE: To review key evidence-based recommendations for the diagnosis and treatment of peripheral facial palsy in children and adults. METHODS: Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on peripheral facial palsy were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. RESULTS: The topics were divided into 2 main parts: (1) Evaluation and diagnosis of facial palsy: electrophysiologic tests, idiopathic facial palsy, Ramsay Hunt syndrome, traumatic peripheral facial palsy, recurrent peripheral facial palsy, facial nerve tumors, and peripheral facial palsy in children; and (2) Rehabilitation procedures: surgical decompression of the facial nerve, facial nerve grafting, surgical treatment of long-term peripheral facial palsy, and non-surgical rehabilitation of the facial nerve. CONCLUSIONS: Peripheral facial palsy is a condition of diverse etiology. Treatment should be individualized according to the cause of facial nerve dysfunction, but the literature presents better evidence-based recommendations for systemic corticosteroid therapy.

RESUMO

RESUMEN Las vasculitis de las arterias o vasculitis cerebelosas en el lupus eritematoso sistémico (LES) son extremadamente infrecuentes y podrían estar inmersas o formar parte de los casos de LES neuropsiquiátrico (LESNP), stroke cerebeloso en el LES y grupo de vasculitis del sistema nervioso central (SNC ) por LES. La adición del manejo quirúrgico a esta entidad, mediante descompresión suboccipital, ha sido reportada en muy pocas publicaciones. Se presenta el caso de una paciente mujer de 18 años con LES, LESNP, stroke cerebeloso, con alta sospecha de vasculitis inflamatoria de las arterias cerebelosas a quien, a pesar del manejo médico, se le brindó descompresión suboccipital. La vasculitis inflamatoria de las arterias cerebelosas en el LES es una causa infrecuente de stroke cerebeloso de elevada mortalidad. Existe limitada evidencia científica en la realización de la descompresión suboccipital de esta entidad.

ABSTRACT Arterial vasculitis or cerebellar vasculitis in systemic lupus erythematosus (SLE) are extremely infrequent, and these might be included within cases of neuropsychiatric SLE (NPSLE), cerebellar stroke in SLE, and within the group of central nervous system vasculitis due to SLE. The addition of surgical management to this condition has been reported in few publications. We present the case of a 18- year old female patient with SLE, NPSLE, and cerebellar stroke, highly suspicious of inflammatory vasculitis affecting cerebellar arteries, in whom, in spite of medical management, suboccipital decompression was performed. Inflammatory vasculitis of cerebellar arteries in SLE is an infrequent cause of cerebellar stroke, and it has elevated mortality rates. There is limited scientific evidence with respect to suboccipital decompression for the management of this condition.

RESUMO

BACKGROUND: Microvascular decompression (MVD), radiofrequency rhizotomy (RFR), and stereotactic radiosurgery (SRS) are surgical techniques frequently used in the treatment of idiopathic trigeminal neuralgia (TN), although the results reported for each of these are diverse. OBJECTIVE: This study aimed to compare long-term pain control obtained by MVD, SRS, and RFR in patients with idiopathic TN. METHODS: To compare the results obtained by MVD, SRS, and RFR we chose a quasi-experimental, ambispective design with control groups but no pretest. A total of 52 participants (MVD n = 33, RFR n = 10, SRS n = 9) were included. Using standardized outcome measures, pain intensity, pain relief, quality of life, and satisfaction with treatment were assessed by an independent investigator. The TREND statement for reporting non-randomized evaluations was applied. Clinical outcomes were evaluated at the initial postoperative period and at 6 months, 1, 2, 3, 4, and 5 years postoperatively. RESULTS: MVD has shown better results in pain scales compared to ablative procedures. Significant differences between groups were found regarding pain intensity and pain relief at the initial postoperative period (p < 0.001) and 6 months (p = 0.022), 1 year (p < 0.001), 2 years (p = 0.002), and 3 years (p = 0.004) after the intervention. Those differences exceeded the thresholds of the minimal clinically important difference. A higher percentage of patients free of pain was observed in the group of patients treated by MVD, with significant differences at the initial postoperative period (p < 0.001) and 6 months (p = 0.02), 1 year (p = 0.001), and 2 years (p = 0.04) after the procedure. Also, a higher risk of pain recurrence was observed in the RFR and SRS groups (HR 3.15, 95% CI 1.33-7.46; p = 0.009; and HR 4.26, 95% CI 1.77-10.2; p = 0.001, respectively) compared to the MVD group. No significant differences were found in terms of quality of life and satisfaction with treatment. A higher incidence of complications was observed in the MVD group. CONCLUSION: Concerning pain control and risk of pain recurrence, MVD is superior to RFR and SRS, but not in terms of quality of life, satisfaction with treatment, and safety profile.

RESUMO

O cisto dentígero é o tipo mais comum de cisto odontogênico de desenvolvimento. Envolve a coroa de um dente impactado e se conecta ao mesmo pela junção amelocementária, sendo mais frequente entre a segunda e terceira década de vida. A presença dessa patologia pode interferir na erupção dentária impactando os dentes permanentes em desenvolvimento. O objetivo deste trabalho é relatar procedimentos cirúrgicos e ortodônticos associados ao tracionamento de unidades dentárias em uma criança de 7 anos com cisto dentígero envolvendo as unidades 21, 22 e 23. O tratamento incluiu a exodontia dos dentes decíduos sobrejacentes, descompressão e enucleação do cisto, tracionamento inicial com aparelho removível e finalização com aparelho ortodôntico fixo.

Dentigerous cyst is the most frequent type of developmental odontogenic cyst. It involves the crown of an impacted tooth and connects to it by the cementoenamel junction. It is more frequent between the second and third decade of life. The treatment involves enucleation, marsupialization/decompression or a combination of these techniques. The aim of this study is to report the surgical and orthodontic procedures of a tooth traction in a 7-year-old child with dentigerous cyst involving units 21, 22, and 23. The treatment included the extraction of the related deciduous teeth, decompression and enucleation of the cyst, initial traction with removable appliance, and finishing with fixed orthodontic appliance. At the end of the treatment, a good occlusion was obtained with significantly improving the smile aesthetics. Therewas no recurrence of the cyst.(AU)
