Impact of Hard Palate Angulation Caused by Septal Deviation on Maxillary Sinus Volume

Abstract

Objective: To investigate the effect of hard palate angulation caused by septal deviation on the volume of the maxillary sinus. Methods:Coronal computed tomographic (CT) scans of 1568 patients aged from 18 to 60 were examined. CT scans of 402 patients were included in the study. On these scans, the maxillary sinus volume, the angle of the nasal septal deviation, and the angulation of the hard palate were calculated using the ImageJ software. Each maxillary sinus volume was statistically compared with each other and with those in the control group. Correlations between palatal angulation and septal deviation were determined.Results: Deviated nasal septum whether with or without deflection of the hard palate was noted to have caused changes in the volume of the maxillary sinus in both female and male patients. The volume of the maxillary sinus on the deviated side was less than that of the opposite side, and the differences between the volumes of both sinuses were statistically significant (p<0.05). No significant differences were noted when compared with the control group. A positive correlation was observed between the nasal septal deviation angle and the angulation of the hard palate. Conclusion:Regardless of whether or not it affects the hard palate, nasal septal deviation reduces the volume of the maxillary sinus on the deviated side but does not affect the total volume of the maxillary sinuses. Significant differences between the volumes on the two sides can lead to facial asymmetry.

Evaluation of the Relationship of Dimensions of Maxillary Sinus Drainage System with Anatomical Variations and Sinusopathy: Cone-Beam Computed Tomography Findings

“…In our study, we found an incidence of 74%. Sapmaz et al [6] found that nasal septal deviation leads to reduced maxillary sinus volume on the deviated side. Our results revealed no significant relation-ship between nasal septal deviation and infundibulum length or ostium height.…”

“…Nasal septal deviation, seen in about 80% of the population, is defined as an asymmetry of the nasal septum, and it may limit air flow and impair the growth of the paranasal sinus. As a consequence, mucosal ciliary activity decreases and bacterial invasion develops [6][7][8]. Additionally, previous studies stated that concha bullosa (pneumatized middle turbinate) adversely affects the paranasal sinus ventilation and mucociliary clearance in the middle meatus region [9].…”

Effect of nasal cavity and nasopharynx architectonic disorders on the paranasal sinus development and sinusitis

“…Есть исследования, в которых была описана связь между объемом ОНП и степенью выраженности ДНП, но для разных пазух эта взаимосвязь была разной. В исследованиях, где ДНП классифицировалась по углу отклонения (слабая степень до 90°, умеренная от 90-150°, тяжелая степень более 150°), при умеренной и тяжелой степени ДНП наблюдались асимметрия и уменьшение объемов ипсилатеральных решетчатых [24], верхнечелюстных [25] и клиновидных пазух [26]. Есть другое мнение, что только умеренное отклонение ДНП влияет на объем ВЧП [27].…”

“…Есть другое мнение, что только умеренное отклонение ДНП влияет на объем ВЧП [27]. Исследования, включающие суммарно 869 обследуемых, показали, что на стороне выраженной деформации перегородки носа объем ВЧП был меньше, чем на контралатеральной стороне [28][29][30][31], где зачастую имелась СВ. При двусторонней СВ наблюдалось увеличение ВЧП с обеих сторон [2].…”
