title: Morphometric analysis of the maxillary sinus in patients with nasal septum deviation.
abstract: The aim of this study was to evaluate the relationship between nasal septum deviation, which is common in the general population, and maxillary sinus volume. A retrospective assessment was made for 96 patients with nasal septum deviation without coexisting sinonasal morbidity and compared to 60 healthy individuals. A three-dimensional reconstruction of computed tomography images was used to assess a total of 312 maxillary sinus volumes. Septal deviation angles and volumes were also measured to standardize and determine the severity of the septal deviations. Septal deviations were right-sided in 36.5% of the cases (n = 35) and left-sided in 63.5% (n = 61). Deviation angles varied between 5° and 24.4°, with a mean value of 12.9 ± 5.0. The mean value for the deviation volume was 4.6 ± 1.5 cm(3) (range 1.7-9.4). The right and left maxillary sinus volumes were 11.8 ± 4.7 cm(3) and 11.5 ± 4.4 cm(3), respectively, in control group. Statistically significant discrepancy was observed between the ipsilateral and contralateral maxillary sinus volumes, in regard to the side of the septal deviation in study group. Maxillary sinus volumes were found to be significantly smaller on the ipsilateral side of septal deviation compared with the contralateral side.
