Maxillary sinus aeration in allergic rhinitis
MetadataShow full item record
Objective: We aimed to investigate the relationship between allergic rhinitis, which is an important reason of nasal obstruction, and maxillary sinus aeration. Patients and Methods: Three hundred fifteen patients who have a complaint of nasal obstruction and scheduled to undergo skin prick test (SPT) with a suspicion of allergic rhinitis (AR) were enrolled for this study. Thirty-two patients with positive SPT result and 30 patients with a negative SPT result were determined as group 1 and 2 (control group), respectively. A 3-dimensional reconstruction of computed tomography images of the 62 patients was used to assess and calculate maxillary sinus volumes (MSVs). Results: Total maxillary sinus volumes were measured as 21.87 cm(3) and 30.15 cm(3) in group 1 and group 2, respectively. A statistically significant difference was observed between the MSVs of the groups (P<0.001). Conclusion: Total maxillary sinus volumes were found to be significantly smaller for patients with a positive SPT compared to patients with a negative SPT. Thus, we may conclude that AR has a negative impact on maxillary sinus aeration.
