Abstract
OBJECTIVE
To clarify the relationship between Eustachian tube dimensions and chronic otitis media aetiology using temporal bone computed tomography.
METHODS
The data of 231 adults who had undergone surgery for unilateral chronic otitis media were reviewed retrospectively. Diseased and healthy ears were enrolled in groups 1 and 2, respectively. Group 1A included chronic otitis media with cholesteatoma (n = 28) and group 1B included chronic otitis media without cholesteatoma (n = 203). The Eustachian tube dimensions of groups 1 and 2 were compared, to clarify the relationship between the Eustachian tube dimensions and chronic otitis media aetiology. Groups 1A and 1B were compared to assess the effect of Eustachian tube dimensions on cholesteatoma development.
RESULTS
The Eustachian tube was shorter, narrower and located more horizontally in ears with chronic otitis media. No significant difference was found between groups 1A and 1B.
CONCLUSION
Eustachian tube dimensions are closely related to chronic otitis media aetiopathology, but are not related to cholesteatoma development.
