          Abstract

          Las deformidades dentofaciales (DDF) son conocidas y su diagnostico es cada vez mas frecuente; las DDF asimétricas son un grupo de enfermedades de complejo manejo debido a las condicionantes estéticas y funcionales comprometidas. La etiología es variada, aunque la hiperplasia condilar suele estar asociada en los pacientes adolescentes y adultos; su diagnostico se establece mediante análisis facial, estudio con medicina nuclear, tomografías computadorizadas y otros exámenes. La terapéutica mas aceptada hoy día consiste en la condilectomia parcial y la corrección de la deformidad facial basada en las necesidades estéticas y funcionales del paciente. El objetivo de esta revisión es determinar las condicionantes actuales asociadas al diagnostico y tratamiento de las DDF asimétricas y el papel que cumple la hiperplasia condilar en el desarrollo de estas alteraciones faciales.

          Dentofacial deformities (DDF) are know and the diagnosis is ever more executed; the asymmetric DDF are a group of disease with difficult management because of esthetic a functional conditions. The etiology is these conditions is varied, although the condylar hyperplasia is frequently in adolescent and adult patients; the diagnosis is realized by facial analysis, nuclear medicine study and computed tomography and others. The more accepted therapy is related to partial condilectomy and facial deformity correction in relation to aesthetic and functional needs of patient. The aim of this review is to determine the current conditions associated to diagnosis and treatment of asymmetric DDF and the role of condylar hyperplasia in the development of these facial alterations.

            Orthognathic surgery and a tale of how three procedures came to be: a letter to the next generations of surgeons.

            Although the transoral sagittal splitting of the ramus, the osseous genioplasty, and the LeFort osteotomy today are common procedures used by many specialties to solve a broad range of problems, this was not always so. This article describes Hugo Obwegeser's firsthand experience of how these procedures came to be.

              Histopathologic comparison of normal and hyperplastic condyles.

              The aim of this study was to compare normal and hyperplastic mandibular condyles using two different histopathologic staining techniques. Nine cases of condylar hyperplasia and 13 normal cases were studied after hematoxylin and eosin and silver staining. There was a significant difference between the two groups in the thickness of the hyperplastic cartilage layer of condylar soft tissue (P = 0.017). Also, the number of argyrophilic nucleolar organizer regions was significantly higher in the condylar hyperplasia case group (P = 0.0001). No significant differences could be demonstrated in cartilage island frequency, penetration depth, and distribution in the cancellous bone of condyles. The thickness of the hyperplastic cartilage layer appears significantly increased in condylar hyperplasia. In addition, argyrophilic nucleolar organizer region count may be useful in histopathological identification of condylar hyperplasia.
