Abstract
OBJECTIVES: This study aims to investigate the prevalence of uncinate process (UP) pneumatization and also to investigate the association of UP pneumatization with concurrent morphological variations in neighboring structures and the presence of maxillary sinusitis.
PATIENTS AND METHODS: This was a retrospective study where coronal computed tomography scans of 1,500 UPs in 750 patients (483 males, 267 females; mean age 36.3±14.7 years; range 7 to 84 years) were examined to determine the prevalence of UP pneumatization and to assess any concurrent neighboring anatomical structures and the presence of maxillary sinusitis between January 2013 and June 2013.
RESULTS: Uncinate process pneumatization was identified in a total of 6.26% of our patients with 1.60% being bilateral, 2.53% on the right only, and 2.13% on the left side only. Other than concurrent occurrences of right maxillary sinus septa (p=0.046), growth of the right ethmoidal bulla (p=0.044) and presence of maxillary sinusitis (right side: p=0.046, left side: p=0.035) were seen.
CONCLUSION: We detected a 6.2% prevalence of UP pneumatization in our study group. An abnormally sized and over-pneumatized UP can cause narrowing of the infundibulum and impaired sinus drainage. Such functional blockage can lead to recurrent maxillary sinusitis, stuffiness, and decreased olfaction.
