Eating with squeaking ears may be due to excessive earwax in the external auditory canal, temporomandibular joint disorder, and abnormal opening of the eustachian tube. 1. Excessive earwax: the skin of the external auditory canal contains ceruminous glands, which will secrete cerumen, also known as earwax, and if the accumulation of earwax touches the tympanic membrane, the earwax will rub against the tympanic membrane with chewing when eating, which will produce sound. 2. Temporomandibular joint disorder: the temporomandibular joint is very close to the ear, when the temporomandibular joint dysfunction occurs, it will lead to increased friction between the joints, and the popping sound will be transmitted to the ear when chewing, and the patient may mistakenly think that it is a squeaking sound inside the ear. 3. Abnormal opening of the eustachian tube: patients with this disease often have the phenomenon of creaking ears when chewing and swallowing. If this symptom occurs, it is recommended to actively consult a doctor for a clear diagnosis.
