Background and Objectives: This study is designed to examine the correlation of the direction of the nasal septum deviation (NSD) and Eustachian tube dysfunction (ETD). Since the Eustachian tube lies between the middle ear and the nasopharynx, we presumed that the direction of the NSD causes narrowing of certain parts of the nasal cavity and can cause the ETD. Materials and Methods: We recruited 50 NSD patients who were in need of septoplasty. We run the test of nasal endoscopy, oto-endoscopy, computed tomography, and Eustachian function test and looked into the correlation of the direction of the NSD and ETD. Results: There were no correlation between the direction of NSD and the side effected by ETD. Conclusion: Narrowed nasal cavity due to NSD is thought to take effect to the pathogenesis of ETD. However, this study has several shortcomings such as small number of enrolled patients and lack of diversity in measuring of Eustachian tube function. Further studies with more patients and detailed considerations are needed, and we plan to design a study that might yield different results.
