Morphometric evaluation of the relationship between the osseous orifice of the auditory tube and the other cranial base structures on the adult skulls

Morphometry of the osseous of the Eustachian tube

Abstract

Purpose: The eustachian tube consists of cartilage, fibrocartilagenous part and osseous part anteriorly from lateral to medial. Functional evaluation of the auditory tube has become important in myringoplasty and tympanoplastic procedures and also 3D modeling. The aim of the study is to perform morphometric measurements of the bony part of the tube and relation with the other anatomical formations at the base of the skull and to give the descriptive values ​​of these values.

Materials and Methods: In the study, measurements of 12 variables were carried out using 26 dry skulls belonging to the bone collection of xxx University Faculty of Medicine, Department of Anatomy. Measurements were made with Somet Inox caliper and SPSS 22.0 program was used for statistical analysis.

Findings: The mean values ​​of the parameters ​​are given. It was observed that the distances between the right and left lateral and medial edges of the osseous orifice of the auditory tube were in relation with each other. In addition, it was also determined that these distances and the bilateral medial pterygoid distance showed a high correlation.

Conclusion: As a result, data were provided for 3-dimensional functional models using the eustachian bone part and also the correlation values between the variables were evaluated.
