Background and Objectives: The normal ear of patients with unilateral otitis media is also often abnormal. Therefore, using the Williams test (Y-226 Hz), we compared the impedance of the normal ear of patients with unilateral otitis media with the impedance of subjects with bilateral normal ears to provide additional data for the evaluation of the normal ear of patients with unilateral otitis media. Materials and Methods: The Williams test (y-226 Hz) impedance characteristics of the normal E-tube (40 ears) and the normal E-tube (33 ears) of patients with unilateral otitis media were compared and analyzed using t-test. Results: The static compliance (SC) in the normal ear of patients with unilateral otitis media was significantly higher than the SC in both normal ears. And the ears of the unilateral otitis media group were located at relatively significantly negative pressure in all atmospheric pressure eustachian tube function test (ETFT ), positive pressure ETFT, and negative pressure ETFT. Additionally, pressure changes and symmetry were relatively good in the ears of the normal group. Conclusion: Even in the normal ear of a patient with unilateral otitis media, there is a possibility that there may be a minor problem with the tympanic cavity, so care must be taken during examination and diagnosis.
