The aims of this article were to describe the surgical technique of the inferior alveolar nerve lateralization followed by implant installation by means of a clinical report and also to discuss the importance of an adequate surgical and prosthetic planning for atrophic posterior mandible rehabilitation.

PURPOSE: The present case describes an inferior alveolar nerve lateralization for implant placement that caused mandible fracture a few days after surgery. CLINICAL REPORT: In this case, a 56-year-old female patient who had a severely atrophied jaw and showing bone height less than 7 mm from the bone crest and the mandibular canal was submitted to surgery lateralization of the inferior alveolar conducted with piezzo. Even with all postoperative care, the patient suffered an incomplete fracture of the mandible a few days after lateralization of the inferior alveolar nerve for implant placement. The patient was treated with soft diet and medications for pain and antibiotics, besides removing the implant associated with the fracture. CONCLUSION: It is suggested that this procedure may be conducted in 2 operative periods: firstly, the lateralization of the inferior alveolar; and secondly, after a period of 3 months, the implant placement in a situation of more bone stability.

Mielografia é uma técnica radiográfica na qual se administra meio de contraste no espaço subaracnóideo para avaliar a medula espinhal. Múltiplas projeções radiográficas fornecem uma exploração circunferencial da medula, auxiliando na localização mais precisa de compressões nesta região. Objetivou-se demonstrar a contribuição das projeções oblíquas, pouco exploradas em exames de mielografia, para a localização de lesões medulares extradurais em cães e gatos causadas por processo degenerativo do disco intervertebral. Foram avaliadas 116 mielografias e observou-se que em 36,2% dos casos as projeções oblíquas foram imprescindíveis para a localização exata das lesões. A associação entre as projeções ventrodorsal e oblíquas se mostraram mais úteis para a localização da lesão do que quando avaliadas isoladamente e as projeções oblíquas esquerda e direita foram igualmente importantes.

The rehabilitation with oral implants is, without any doubt, a consecrated technique. But often we face situations of high bone atrophy where the conventional installation of dental implants is not possible. The posterior mandible, when severely resorbed, generally requires complex techniques to be rehabilitated with implants, such as the lateralization of the inferior alveolar nerve. As an option for these cases, this paper proposes the use of short implants for the rehabilitation of severely resorbed posterior mandible. Copyright © 2013 by Mutaz B. Habal, MD.

The alar base widening is directly related to the Le Fort I osteotomy which could lead to an undesirable facial change if not adequately controlled transoperatively. Several surgical techniques to control the lateralization and widening of the nasal base have been described in the literature. The extraoral technique, first described by Shams and Motamedi in 2002 seems to make this procedure more predictable and reliable. The authors preset a modification for that technique. © 2013 Asian AOMS, ASOMP, JSOP, JSOMS, JSOM, and JAMI.

INTRODUÇÃO:Com o aumento da população idosa, fica evidente a importância de compreender e explorar o processo de envelhecimento humano, o qual acarreta transformações morfológicas e funcionais.OBJETIVOS:Avaliar e comparar as inclinações anteroposterior e lateral do centro de gravidade por faixas etárias.MÉTODOS: Estudo transversal e exploratório. Fizeram parte da pesquisa 135 sujeitos, separados em faixas etárias: Grupo 1: 20-29 anos (n=26), Grupo 2: 30-39 anos (n=26), Grupo 3: 40-49 (n=25), Grupo 4: 50-59 anos (n=30) e Grupo 5: >60 anos (n=28). Esses sujeitos foram selecionados de acordo com o escore do Miniexame de Estado Mental e pela capacidade de permanecer em pé por, pelo menos, 90 segundos. As posturas foram avaliadas por meio do software de avaliação postural (SAPO). As comparações entre os valores de inclinações dados pelo SAPO foram feitas pelo teste de Mann-Whitney (comparação par-a-par), sendo aceito um valor de p<0,05 como significante.RESULTADOS:Na comparação da média da assimetria frontal entre as faixas etárias, observa-se maior lateralização com o avançar da idade, com valores significativos nos grupos 50-59 e >60 anos. Na comparação da média da assimetria sagital entre as faixas etárias, valores são significativos no grupo dos >60 anos.CONCLUSÕES:Após avaliar e comparar as assimetrias sagitais e frontais, pode-se apontar que na medida em que a idade avança, há tendência ao aumento de suas projeções anteriores e laterais comparadas ao centro de gravidade.

Thoracolumbar disk extrusion is the most common cause of extradural compression of the spinal cord in dogs. Myelography is one of the most commonly performed techniques for the diagnosis of this affection. This study aimed to evaluate the applicability and effectiveness of lumbar myelography in the diagnosis of thoracolumbar intervertebral disk extrusion in dogs, as well as its major complications. Twenty dogs were used in this study. Animals were included when neurological examination suggested thoracolumbar spine lesion, myelography was used as a complementary diagnostic method, and diagnosis of disk extrusion was surgically confirmed. The accuracy of the exam to predict location and lateralization of extruded disk material were evaluated, as well as complications associated to the procedure. Lumbar myelography exhibited 95% and 60% accuracy for location and lateralization of the lesion, respectively, with minimal complications.

Data relative on the side occupied by females in double beds were collected in order to evaluate the feasebility to carryout a more extensive study to determine if this behavioral pattern is lateralized. Information relative to the side occupied in the bed, manual lateralization, how long lived togheter, and other related questions were collected in a sample of 229 women aged from 20 to 65 years old. Total frequencies of the bed side occupied showed to be equivalent, however, the left side showed to be chosen significantly more (70%)(χ2 = 5.4; 1 d.f.; p<0.05) when the choice was stated to be spontaneous (i.e, not determined by an impositive factor) . It is concluded that the obtained data give favourable support to an extensive study on the subject, which inserts into the area of research devoted to the understanding of the functional characteristics of central nervous functioning.
