ABSTRACT
The aim of this research was to evaluate the risk factors related to condylar resorption (CR) after orthognathic surgery. Was realized a systematic review with a search of the literature performed in the electronic databases PubMed, MedLine, Ovid, Cochrane Library for current evidence in the world literature as conducted, and relevant articles were selected in according to inclusion and exclusion criteria and the findings were compared. Eight papers, (follow-up 12 months to 69 months) were including. A sample of 2567 patient with mandible or bi maxillary surgery with an age range from 14 to 46 year old was observed. In 137 patients (5.3 percent) CR was observed , with a 97.6 percent (122) female. CR was related to 118 cases with mandibular deficiencies with high mandibular plane (advancement surgery). CR were present principally in bi maxillary surgery with a 103 cases (75.2 percent) and only two papers show any analysis to the relation with TMJ dysfunction. Current evidence in CR is poor but supports those female patients with mandibular deficiency and high mandibular plane angle submitted to bi maxillary surgery with change in occlusal plane (counterclockwise) are associated with condylar resorption after orthognathic surgery...
RESUMEN
El objetivo de esta investigación fue evaluar los factores de riesgo asociados a reabsorción condilar (RC) posterior a cirugía ortognática. Fue realizada una revisión sistemática con una búsqueda de la literatura realizada en bases de dato electrónicos como PubMed, MedLine, Ovid, Cochrane Library buscando actual evidencia en la literatura mundial; artículos relevantes fueron seleccionados según los criterios de inclusión y exclusión, comparando sus resultados. Ocho artículos (tiempo de seguimiento de 12 a 69 meses) fueron incluidos. Se observó una muestra de 2567 pacientes con cirugía mandibular o bimaxilar con una edad de entre 14 y 46 años. En 137 pacientes (5,3 por ciento) se observó reabsorción condilar, siendo el 97,6 por ciento (122 casos) de sexo femenino. La RC fue observada n 118 casos de deficiencia mandibular con un plano mandibular alto (cirugía de avance mandibular). La RC estuvo presente principalmente en cirugías bimaxilares con 103 casos afectados (75,2 por ciento) y solo dos artículos evidenciaron análisis previo de disfunción de ATM. Actualmente la evidencia en RC es limitada pero fundamenta que mujeres con deficiencia mandibular y alto plano mandibular sometidas a cirugía bimaxilar con alteración del plano oclusal (giro horario) son asociadas a la reabsorción condilar después de la cirugía ortognática...
