Adaptación transcultural del instrumento Orthognathic Quality of Life questionnaire al español para el estudio de la calidad de vida de pacientes con anomalías dentofaciales. Fase I / Cross-cultural adaptation of the Spanish language versión of the Orthognathic Quality of Life questionnaire for the assesment of quality of life in dentofacial deformities. Phase I

Antecedentes: La cirugía ortognática es una opción terapéutica que busca parámetros de simetría, función masticatoria, respiratoria, e indirectamente mejorar el estado emocional de pacientes con anomalías dentofaciales. El instrumento Orthognathic Quality Of Life Questionnaire (OQLQ) permite realizar una evaluación subjetiva amplia y del nivel de calidad de vida pre y postquirúrgica, por lo que es necesario realizar el proceso de traducción al español y la adaptación cultural al contexto colombiano. Métodos: Posterior a la autorización del autor original se realizaron traducciones directas, obtención de una versión preliminar, traducciones inversas y una prueba piloto con 15 pacientes colombianos, mayores de 16 años, con anomalía dentofacial que asistieron al hospital de San José. Se aplicó la metodología del grupo de calidad de la European Organization for Research and Treatment of Cancer (EORTC) para garantizar que la versión en español de la escala sea equivalente conceptualmente a la original. Resultados: Las traducciones directas fueron consistentes, sin embargo, se hicieron ajustes para obtener la versión preliminar; las traducciones inversas fueron similares a la versión original de la escala. La prueba piloto, realizada en una muestra heterogénea de 15 pacientes, llevó al ajuste de la sintaxis de un ítem. De esta manera se obtuvo la versión en español del cuestionario que en fase posterior se validará. Conclusiones: La realización de este estudio permitió la adaptación de un cuestionario entendible en el contexto colombiano, garantizando una equivalencia lingüística y conceptual entre esta versión y la versión original

Introduction: Orthognathic surgery is a therapeutic option that seeks parameters of symmetry, masticatory function, breathing, and improves the emotional state of patients with dentofacial anomalies. The questionnaire Orthognathic Quality of Life Questionnaire (OQLQ) allows to make a subjective evaluation and the level of quality of life before and after surgery, so it is necessary to perform the translation into Spanish and the cultural adaptation to the Colombian context. Methods: After the authorization of the original author, direct translations were made obtaining a preliminary version, reverse translations and a pilot test was accomplished with 15 Colombian patients over 16 years of age with a dentofacial anomaly who attended the San José hospital in Bogotá. The methodology of the quality group of the European Organization for Research and Treatment of Cancer (EORTC) was applied to ensure that the Spanish version of the scale is conceptually equivalent to the original. Results: The direct translations were consistent, however, adjustments were made to obtain the preliminary version; the inverse translations were similar to the original version of the scale. The pilot test, carried out on a heterogeneous sample of 15 patients led to the adjustment of the syntax of one item. In this way, the Spanish version of the questionnaire was obtained. Conclusion: The realization of this study allowed the adaptation of an understandable questionnaire in the Colombian context, guaranteeing a linguistic and conceptual equivalence between this version and the original versión

Disc repositioning plus temporal eminectomy for temporomandibular joint internal derangement: A pilot study.

INTRODUCTION: Temporomandibular joint internal derangement is a common disorder, which usually resolves with conservative management. However, 5% of patients require surgery and although many techniques have been described, a gold standard surgical procedure has not yet been established. OBJECTIVES: The aim of this study was to compare the clinical outcome of disc repositioning plus temporal eminectomy versus disc repositioning alone, for the treatment of temporomandibular joint internal derangement. METHODOLOGY: Matched case-control retrospective pilot study. Records of patients diagnosed with temporomandibular joint internal derangement from January 2010 to December 2015 were studied. Eleven patients treated with disc repositioning plus temporal eminectomy for the case group and 11 patients treated with disc repositioning alone for the age- and gender-matched control group. RESULTS: No difference was found in terms of pain, noise or blockage with the maximum oral opening between the groups at the first or sixth month after surgery. However, there were differences in movement restriction at the first and sixth month after surgery, in favor of the temporal eminectomy group. These differences were statistically significant only at the sixth month after surgery (P: 0.03). CONCLUSIONS: Our results suggest that disc repositioning plus temporal eminectomy could be a short-term benefit in terms of mobility and oral opening. However, larger samples and prospective trials will be necessary to corroborate the current findings.
