| Resumo: | Objectives:To investigate a possible relationship between altered nasalflow and chronic otitis media (COM) usingcomputationalfluid dynamics (CFD).Study Design:Retrospective case series.Methods:Retrospective cohort sample of CT scans from patients with COM and controls without COM to compare theresults of various nasal airflow parameters determined by CFD between a group of patients with COM (N=60) and a controlgroup of subjects without any evidence of ear disease (N=81).The CT were subjected to various procedures to carry out CFD studies, determining the resistance to nasalflow, theproportion offlow through the right and left nasal cavity, and two nondimensional estimators. The results of CFD studiesbetween patients with COM and controls were compared.Results:Whereas only 12.3% of the controls had CFD alteration (10 out of 81), 43.3% of the patients suffering COMdisplayed alterations of our nondimensional parametersR φ(26 out of 60).Conclusions:According to our results, the incidence of alterations in nasal airflow by studying with CFD is significantlyhigher in patients with COM than in controls. To our knowledge, this is thefirst article linking nasal cavity and COM using aCFD approach. Our results support the hypothesis that nasalflow alterations could be implicated in the etiopathogenesis ofthe COM.Key Words:Chronic otitis media, middle ear cholesteatoma, computationalfluid dynamics, CFD tools, nasal obstruction,deviated nasal septum, dimensionless estimators.Level of Evidence: 4 |
