Dental Volumetric Tomographical Evaluation of Location and Prevalence of Maxillary Sinus Septa
(Cukurova Univ, Fac Medicine, 2013) Damlar, Ibrahim; Evlice, Burcu Keles; Kurt, Sule Nur
Purpose: The aim of this study was to determine the prevalence and location of maxillary sinus septa using dental volumetric tomography. Material and Methods: This retrospective study was based on the analysis of dental volumetric tomography images for maxillary sinus in patients who visited Cukurova University, Faculty of Dentistry, Department of Oral Maxillofacial Radiology for various reasons between January 2010 to October 2011. After exclusion of patient with prior maxillary sinus surgery and presenting any pathologic conditions, 760 patients (1520 maxillary sinuses) were assessed. Analyses of maxillary sinus septa location were made for three regions: anterior for 1st and 2nd premolar, middle for 1st and 2nd molar, posterior for 3rd molar. Results: 47 of maxillary sinus septa existed in the anterior zone (24.7%), 35 of them in the middle zone (18.4%) and 108 of them in the posterior region (56.8%). Conclusion: The formation of the maxillary sinus septa was affected by the existence or lack of the teeth. Correct detection of the presence of maxillary sinus septa was important prior to sinus lifting and dental implant surgery. Dental volumetric tomographical evaluation of maxillary sinus septa was more useful for a correct diagnosis and treatment planning.
