Introduction
If cerumen impaction occurs in the ear canal, it may cause tinnitus. First, if the impacted cerumen is relatively small in volume or is loosely packed, changes in head or body position—such as those occurring during walking, running, or other physical activities—may alter the configuration of the ear canal. During such positional changes, the cerumen impaction may collide with or rub against the walls of the external auditory canal, thereby producing various tinnitus sounds.
People often encounter unusual phenomena in daily life. For instance, recently, many have heard about a condition called “cerumen impaction.” Many individuals are likely unfamiliar with this term and may not understand what it is or what symptoms it entails. So, can cerumen impaction cause tinnitus?
Can cerumen impaction cause tinnitus?
If cerumen (earwax) becomes impacted within the ear canal, it may indeed trigger tinnitus. First, if the impacted cerumen mass is relatively small or loosely packed, changes in head or body position—such as those occurring during walking, running, or other physical activities—may cause the cerumen to shift. During such positional changes, the impacted cerumen may rub against or collide with the walls of the external auditory canal, producing various tinnitus sounds. Second, if the cerumen impaction is large or completely obstructs the ear canal, incoming external sounds may elicit abnormal auditory reflexes, which can also lead to tinnitus or auditory hallucinations.
There are two common mechanisms by which cerumen-induced tinnitus occurs. First, the ear canal may become partially or fully blocked, resulting in a sensation of buzzing or ringing in the ear. Second, when chewing or moving the head, the impacted cerumen may come into contact with the tympanic membrane (eardrum), generating sounds caused by friction between the cerumen and the eardrum. These sounds are typically not continuous but are instead triggered only by specific movements. Clinically, it is essential to carefully differentiate the underlying cause of tinnitus.
With prompt and appropriate treatment, tinnitus caused by cerumen impaction usually resolves rapidly. We hope this explanation proves helpful to you.
