Item Estudo da Relação entre Hiperatividade dos Músculos Esfenomandibulares e dor ocular(Universidade Federal de Goiás, 2010-07-13) BORGES, Raulino Naves; ÁVILA, Marcos; http://lattes.cnpq.br/3335187297522447study was based on the hypothesis that a TMD can be the etiological factor in ocular pain and to test it the authors performed a clinical evaluation in TMD patients presenting with sphenomandibular muscle hyperactivity. The hypothesis is based on the fact that the muscle originates in the lateral aspect of the orbit, with a point of insertion in the mandible. It is an observational and descriptive study, characterized by: 1) an anatomical investigation performed in cadavers and 2) a clinical interpretation of the physiological relationship between sphenomandibular muscle functions and symptoms involving temporomandibular disorders presenting with ocular pain. Ten anatomical specimens (five cadavers) from the Anatomy Department of the School of Medicine of the Catholic University of Goiás were examined. One hundred three patients with temporomandibular disorders (TMD) were treated and followed in the Outpatient Clinic of the School of Dentistry of the Federal University of Goiás for the purpose of studying the interrelationship between cervical and craniofacial pain symptoms and craniomandibular disorders. The work was carried out in the Outpatient Clinic of the School of Dentistry of the Federal University of Goiás, between April 2006 and December 2008. Inclusion criteria, used to form Group I, totaling 58 patients, included temporomandibular disorders, referred ocular pain and sphenomandibular muscle hyperactivity. Group II comprised 45 patients who did not present with sphenomandibular muscle hyperactivity. All the patients received treatment for Temporomandibular Disorder (Groups I and II) and were followed for two years, with biannual evaluation visits. Response to treatment was evaluated by means of an opinion-based questionnaire that served to stratify the level of ocular pain, which was reported as eliminated in 46 of the 58 patients in Group I (79.3%) and in eight Group II patients (17.8%). This evaluation has made it possible for the authors to affirm that the sphenomandibular muscle is independent from the temporal muscle and is closely related to the orbit; the clinical examinations conducted along the study enabled the evaluation of sphenomandibular muscle hyperactivity in temporomandibular disorder episodes; and this hyperactivity is significantly associated to the presence of referred ocular pain.Item Avaliação da eficácia da dilatação com cateter-balão (dacrioplastia) para o tratamento das obstruções congênitas do ducto lacrimonasal(Universidade Federal de Goiás, 2010-06-29) CARVALHO, Roberto Murillo Limongi de Souza; ÁVILA, Marcos; http://lattes.cnpq.br/3335187297522447The most common etiology for congenital epiphora is the obstruction of the lacrimonasal duct. Congenital obstruction of the lacrimonasal duct (CLNDO) is the most frequent abnormality of the lacrimal sac of the child. It s incidence varies from 1.8% to 20%. The purpose of this study was to evaluate the efficacy of lacrimonasal duct dilatation using balloon-catheter for treatment of CLNDO in children between two and six years old. Besides, to evaluate the anatomical findings of lower lacrimal system of children with CLNDO using multi-detectors computerized tomography dacryocystography (MD-CT-DCG) with three dimension (3D) reconstruction, before and after the balloon-catheter dilatation. This was a prospective interventional case series study, performed with children treated at the Centro de Referência em Oftalmologia (CEROF) from the Universidade Federal de Goiás, with CLNDO. The cases were selected consecutively accordingly with the demand of the service. Thirthy-eight lacrimal systems from 29 children with CLNDO were included and treated with balloon-catheter dilatation. The age varied from 24 to 64 months, with average of 38.13 ± 11.26 months. Among the 38 lacrimal systems treated, 33 had complete resolution of the signs and symptoms of epiphora (success rate of 86.84%). A radiological study from the last 18 operated lacrimal systems was performed before and five minutes after balloon-catheter dacrioplasty. The circumference of the largest portion of lacrimal system, measured before the procedure, varied from 0.64 to 2cm with an average of 1.30 ± 0.45cm. The amount of contrast prior to the procedure varied from 0.01 to 0.38cm3, with an average of 0.12 ± 0.08cm3. The amount of contrast after the procedure varied from 0.01 to 0.20cm3, with an average of 0.07 ± 0.06cm3 (p = 0.01). The multivariate logistic regression analysis ( backward" model) showed that the difference in the amount of contrast before and after the procedure (p=0,04) and the largest portion of lacrimal sac (p=0,01) were the variables determining for the success of the procedure. There were no complications with the procedure. In conclusion, the balloon-catheter dilatation was proved to be effective as the first procedure in the vast majority of children with CLNDO. The technique of MD-CT-DCG-3D provides detailed information about the anatomy of the lacrimal system, including the lacrimal flow immediately after the dilatation. The difference in the amount of contrast before and after the procedure and the largest portion of lacrimal sac were the variables determining for the success of the procedure.
