Objectives: The aim of this study is to determine the prevalence of NSD, CB and maxillary sinusitis and to investigate their possible correlation using CBCT in a group of adult Egyptian population.
Subjects &methods: In this retrospective study, 75 CBCT scans of both sexes (29 males & 46 females) in the age range between 13-61 years were selected from the archives of the Oral and Maxillofacial Radiology Department, Faculty of Dentistry, Cairo University. The presence of nasal septal deviation (NSD), concha bullosa (CB) as well as maxillary sinusitis and their correlation was assessed by an experienced Oral and Maxillofacial Radiologist.
Results& conclusions: The results of this study showed that maxillary sinusitis is quite common (62.7%) in the studied population. The prevalence of maxillary sinusitis was more common than both NSD and CB. No correlation between all examined parameters was found except an association between NSD and contralateral CB. There was also no statistically significant difference between both genders in all parameters. From the results of this study it can also be concluded that neither NSD, nor CB increases the incidence of maxillary sinusitis.
