RESULTS: Mastoid air cell volume, as well as maxillary sinus volume, of the deviated side was smaller than that of the contralateral side, but these were not statistically significant. There was no correlation between NSA and volumes of mastoid air cell and the maxillary sinus. There also was no correlation between NSD/NC ratio and mastoid air cell and maxillary sinus volumes. Significant linear and growth regression was found between age and volume of the mastoid air cell and maxillary sinus but not between age and NSA and NSD/NC ratio. CONCLUSION: Mastoid air cell volume and maxillary sinus volume of the deviated side tended to be smaller than those of the contralateral side, which suggests that NSD can influence both aerations. However, because the degree of NSD did not correlate with the volumes of the mastoid air cell and maxillary sinus in this study, we should consider that further possible factors may be involved in both aerations.
