Prevalence of Maxillary Sinus Disease and Abnormalities in Patients Scheduled for Sinus Lift Procedures

Background: The purpose of the present study was to determine the prevalence of sinus disease and abnormalities among patients scheduled to undergo direct sinus augmentation. Methods: Forty‐five patients attending a private periodontal practice and consecutively treatment planned for sinus augmentation were referred for otorhinolaryngologic evaluation, which included a medical history and radiographic (computed tomography), clinical, and endoscopic examinations. Pathological findings were recorded and otorhinolaryngologic treatment was provided. Six months later the sinus augmentation procedure was performed and followed by postoperative evaluations for 4 to 6 months. Results: Of the 45 subjects, 98% (44) were diagnosed with chronic periodontitis, 51% were smokers, and 27% reported a history of symptoms indicative of sinus disease. Eighteen subjects were diagnosed with sinus disease and/or abnormalities. The diagnosed conditions included chronic sinusitis, sinus cysts, nasal septum deviation, and ostium stenosis. No significant differences in age, gender, or smoking status between patients with and without sinus conditions were found (P >0.05). There was a significant association between history of symptoms and diagnosis of sinus conditions (P
