ABSTRACT
Hemifacial spasm (HS) is a movement disorder characterized by paroxysmal and irregular contractions of the muscles innervated by the facial nerve. Chiari malformation type I (CM I) is a congenital disease characterized by caudal migration of the cerebellar tonsils, and surgical decompression of foramen magnum structures has been used for treatment. The association of HS with CM I is rare, and its pathophysiology and therapeutics are speculative. There are only a few cases reported in the literature concerning this association. The decompression of the posterior fossa for the treatment of CM I has been reported to relieve the symptoms of HS, suggesting a relation between these diseases. However, the possible complications of posterior fossa surgery cannot be underrated. We report the case of a 66-year-old patient, in ambulatory follow-up due to right HS, no longer responding to botulinum toxin treatment. Magnetic resonance imaging (MRI) of the skull revealed compression of the facial nerve and CM I. The patient underwent surgery for HS by neurovascular microdecompression of the facial nerve via right lateral suboccipital craniectomy, but presented significant clinical worsening in the postoperative period even though the cerebellum edema related to surgical manipulation was mild. Due to the clinical worsening, the patient underwent a median suboccipital craniectomy with decompression of the foramenmagnum structures. After this second surgery, the patient had progressive improvement and was discharged from the hospital for ambulatory care.

Introduction Vertebroplasty and kyphoplasty are possible options for vertebral augmentation after osteoporotic fractures. Both are percutaneous techniques with specific advantages and disadvantages. Our aim is to compare the clinical and radiological results of these two procedures. Methods An overview of published systematic reviews in the literature on the effects of kyphoplasty compared with vertebroplasty was performed. Results After short and long follow-up, the kyphoplasty group had lower pain scores on the visual analogue scale (VAS), lower scores in the Oswestry Disability index (ODI), greater restoration of the vertebral body height and lower kyphosis angle in the immediate postoperative period. There was less leakage of cement to the vertebral canal and extraspinal spaces. Conclusions Compared with vertebroplasty, kyphoplasty achieved better results in pain relief, quality of life, correction of spinal deformity and lower risk of cement leakage.
Introdução Vertebroplastia e cifoplastia são opções possíveis de tratamento para fraturas vertebrais osteoporóticas. Ambas são técnicas percutâneas com vantagens e desvantagens específicas. Nosso objetivo é comparar os resultados clínicos e radiológicos dos dois procedimentos. Métodos Foi realizada uma revisão sistemática da literatura publicada sobre os efeitos da cifoplastia em comparação com a vertebroplastia. Resultados No acompanhamento a curto e longo prazo, o grupo de cifoplastia teve valores mais baixos na escala visual analógica (EVA) de dor, valores mais baixos no índice de incapacidade de Oswestry (IIO), maior restauração da altura do corpo vertebral e menor ângulo de cifose no pós-operatório imediato. Houve menor incidência de extravasamento de cimento no canal vertebral e nos espaços extraespinhais. Conclusões Em comparação com a vertebroplastia, a cifoplastia obteve melhores resultados no alívio da dor, na qualidade de vida, na correção de deformidade espinhal e menor risco de extravasamento de cimento.

ABSTRACT Burr hole evacuation has been the most frequently-used procedure for the treatment of chronic subdural hematomas (CSDH). Objective: To evaluate whether the use of a drain and/or the number of burr holes for treatment of CSDH modifies the rates of recurrence and complications. Methods: A retrospective review of 142 patients operated on because of CSDH, between 2006 and 2015, analyzing recurrence and complications of the use of one or two burr holes with or without the use of a drain. Results: Thirty-seven patients had bilateral CSDH (26%) and 105 (73.9%) patients had unilateral CSDH. Twenty-two (59.4%) patients were given a drain and 15 (40.6%) were not. A total number of recurrences occurred in 22 (15.5%) patients and the total number of complications was in six (4.2%) patients. Mean follow-up time was 7.67 months. Conclusions: The number of burr holes and the use of the drain did not alter the rates of recurrence and complications in the treatment of CSDH.
RESUMO A trepanação é o procedimento mais utilizado para o tratamento de hematomas subdurais crônicos (HSDC). Objetivo: Avaliar o uso de dreno subdural e / ou o número de trepanações para tratamento de HSDC modifica as taxas de recidiva e complicações. Métodos: Uma revisão retrospectiva de 142 pacientes operados por HSDC entre 2006 e 2015 analisando recidiva e complicações usando um ou dois orifícios com ou sem uso de dreno. Resultados: Trinta e sete casos apresentaram HSDC bilaterais (26%) e 105 (73,9%) unilaterais. Em vinte e dois (59,4%) casos houve uso de dreno e em 15 (40,6%) não houve. O número total de recidivas foi de 22 casos (15,5%) e o número total de complicações foi de 6 casos (4,2%). O tempo médio de seguimento foi de 7,67 meses. Conclusões: O número de trepanações e o uso do dreno não alteraram as taxas de recidiva e complicações no tratamento de HSDC.
