Background and Objectives : This study aimed to evaluate the relationship between the location of the nasal fontanelle and either the chronic rhiosinusitis with nasal polyp in middle meatus (NP) or the chronic maxillary sinusitis (CMS).
Subjects and Method : We classified the subjects without any nasal septal deviation (<5°) into three groups: the normal control group, the CMS group (CMS without NP) and the NP group (CRS with NP). Both angles of nasal septum and fontanelle were measured by CT imaging and nasal cavities were counted as an individual side. We compared 96 CT scans of normal controls with 79 of CMS groups and 54 of NP groups. In case of discrepancy in the locations of both fontanelles on their CT scans, we reconstructed all the images to identify the fontanelle location. The lateral side on which the fontanelle was actually located was assigned the positive angle and the medial side the negative angle to determine the presence of fontanelle deviation. The normal range of the fontanelle deviation was established by the mean angle obtained from the normal group, which included 50% of each medial and lateral side.
Results : The mean angles of the control group, the CMS group and the NP group were 1.34°, 3.47°, and 6.99°, respectively. A statistically significant relationship was noted between the control and NP group (p=0.001), but not between the control and CMS group, CMS and NP group (p=0.237 and 0.051, respectively).
Conclusion : The nasal polyp in middle meatus influenced on the location of nasal fontanelle to lateral side compared to the normal controls.
