Abstract
Abstract. Oroantral communication (OAC) is a pathological condition characterized by the presence of an abnormal communication between the maxillary sinus and the oral cavity. Once an OAC has established, the closure of this defect is desired in order to avoid infection of the maxillary sinus, and possible difficulties in swallowing, speaking and chewing. Several treatments have been suggested for this condition, both surgical and non surgical. Surgical treatments consist of relocating local or regional tissue and grafting. The purpose of this work is to show the effectiveness of local plastic closure using a palatal flap. Two clinical cases are presented and a revision of literature was performed in order to clarify its advantages and disadvantages.

DISCUSIÓN Las CBS son frecuentes en cirugía Bucomaxilofacial, está indicado tratarlas ya que a punto de partida de ellas se pueden producir complicaciones infecciosas como la sinusitis, y/o dificultades funcionales en la deglución, fonación y masticación Se debe arribar a un diagnóstico minucioso, conociendo en qué condiciones se encuentra el seno maxilar, el tamaño, localización de la CBS así como estado de los tejidos peri-lesionales
CONCLUSIONES La utilización del colgajo palatino para el cierre de CBS ha demostrado ser una técnica muy segura, de fácil realización y que no produce alteraciones importantes de la anatomía de la región a largo plazo, por lo que creemos que debe ser tenida en cuenta al momento de realizar plastias en la zona premolar molar del maxilar superior
Summary
Oroantral communication (OAC) is a pathological condition characterized by the presence of an abnormal communication between the maxillary sinus and the oral cavity. Las CBS afectan por definición tres planos, que son la mucosa sinusal o membrana de Schneider, hueso maxilar superior o palatino y el mucoperiostio bucal (Ries Centeno, 1987; Gay Escoda (2011).
