Summary
Active middle ear disease (MED) can temporarily reduce cochlear implant (CI) function, affecting hearing and impedance. This suggests MED may necessitate CI programming adjustments.
Area of Science:
- Otolaryngology
- Audiology
- Biomedical Engineering
Background:
- Cochlear implant (CI) function is generally considered independent of middle ear aeration and inflammation.
- Clinical observations suggest a temporal link between active middle ear disease (MED) and decreased CI performance, particularly at apical electrodes.
Purpose of the Study:
- To demonstrate the negative impact of active MED on subjective hearing and objective impedance measures in a CI patient.
Main Methods:
- Case study design.
- Monitoring subjective hearing complaints.
- Objective impedance measurements in a cochlear implant patient.
Main Results:
- Significant decrease in subjective hearing during active MED.
- Significant increase in impedance levels during active MED.
- No significant changes observed when the patient did not have active MED.
Conclusions:
- Middle ear disease (MED) can negatively affect cochlear implant (CI) function in some individuals.
- Patients with CI may require adjustments in programming during episodes of MED.

The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...
