Evaluation of relationship between paradoxica l middle turbinate and condition (openng or blockage of ostium) of maxillary sinus ostium in cone beam computed tomography images in an Iranian population

Abstract

Introduction: Concha bullosa and paradoxical middle turbinate (PMT) can impair ventilation and drainage of the maxillary sinus and increase the risk of mucosal disease. Due to the high prevalence of sinus-related inflammatory diseases in the community and the problems that arise for patients, this research was conducted to investigate the relationship between paradoxical interconnection and the obstruction (open and closed) status of maxillary sinus stoma in Iranian society.

Materials and methods: In this descriptive study, the analysis of all available CBCT stereotypes of people referring to Tabriz Dentistry Faculty from September2018 to the end of December 2019 were examined. 182 Of the CBCTs (Cone Beam Computed Tomography)compliant with the research inclusion and exclusion criteria (in the coronal section), the prevalence of PMT in the study population was calculated. The PMTs were selected and the samples were examined for openness or closure of the maxillary sinus stoma, the presence or absence of Concha bullosa the presence or absence of Concha hypertrophy in the coronal sections to determine the relationship between these cases. Data were analyzed by 20SPSS statistical software and chi-square test and logistic regression.

Results: The prevalence of paradoxical intermediate tuberculosis (PMT) was 31.32%, the prevalence of conjunctivitis was 50%, and the prevalence of Concha hypertrophy was 67.03%. Open stoma was also observed in 93.41% of the subjects. The prevalence of the variables studied was similar on both sides (right and left). There was no significant relationship between the prevalence of PMT and the status of obstruction (open and closed) of the stoma. There was no significant relationship between the prevalence of PMT and the condition of conjunctivitis and the status of Concha hypertrophy.

Conclusion: There was no significant relationship between paradoxical middle cone and maxillary sinus stoma obstruction.
