ABSTRACT
La elevación de piso de seno maxilar es uno de los procedimientos preimplantares másrealizados en la práctica odontológica. El objetivo de este artículo es reportar la evidenciadisponible sobre las implicaciones anatómicas y clínicas del procedimiento de elevación depiso para toma de decisiones clínicas. A partir de una búsqueda en la base Pubmed, se hizouna revisión de literatura de artículos publicados en revistas de odontología y otorrinolaringologíaentre 1980 y el 2011. La literatura encontrada se organizó en los siguientes temas:anatomía del seno maxilar, patología del seno maxilar, técnica de elevación de piso deseno maxilar y complicaciones por elevación de piso de seno maxilar. Con relación a otrosprocedimientos con la misma indicación, la elevación de seno maxilar es el más reportadoy ofrece los resultados más predecibles. Hay pocos estudios que reportan complicacionespor elevación de piso de seno maxilar y su manejo...
Maxillary sinus augmentation is one of most commonly performed clinical dental proceduresprevious to implant treatment. The aim of this article is to report the available literatureabout anatomical and clinical implications of the maxillary sinus lift procedure to supportclinical decisions. A literature review of articles published between 1980 and 2011 in dentaland otolaryngology journals was carried out at the Pubmed database. Found referenceswere grouped in the following themes: maxillary sinus anatomy, maxillary sinus pathology,maxillary sinus augmentation technique, and complications for maxillary sinus augmentation.Among other procedures performed for similar conditions, maxillary sinus augmentationis the most reported and the one that provides the most predictable results. Only afew studies report complications and management problems with the maxillary sinus lift...

Surgical intervention in the posterior maxillary region requires detailed knowledge of maxillary sinus anatomy and the possible anatomical variations. This study evaluated the incidence, location of maxillary sinus septa by using radiographic (panoramic radiography and computed tomography) findings and comparison of panoramic radography with CT in antral anatomical variation. This study was based on data from 70 sinuses in partial dentate maxilla. The sample consisted of 61 patients(25 women and 36 men, with ages ranging between 19 and 77 years and a mean age of 49.4+/-11.3 years) who were being treatment-planned to receive implant-supported restorations. First, the panoramic images were examined for the presence of antral septa by radiologist and examiner who don't know about CT findings. And incidence of antral septa was evaluated using an axial plane of CT image. The incidence of septa was compared between panoramic radiography and CT. The accuracy of the incidence was compared between radiologists and dentists. A total of 20 septa were found in 70 sinuses on CT image and the prevalence of one or more septa per sinus was found to be 28.6%. The assumed incidence of septa on panoramic radiography was 27.6%+/-2.2% in radiologist and 31.9%+/-5.8% in dentists. Erroneous diagnosis rate was 11.42% in radiologist and 15.96% in dentists. 40% of antral septa were located in the anterior(premolar) region, 30% of septa were located in the middle(first molar) and posterior(second molar) region separately. Prior to implant placement, it seems appropriate to consider panoramic radiography as a standard radiographic examination and periapical radiographs may be used to complete the findings in regions not sharply depicted in the panoramic radiograph. And cross-sectional imaging should be used in sites with severe bone loss and close proximity of the maxillary sinus.
