Conductive hearing loss is a type of hearing loss where the ear’s ability to transmit sound from the outer and middle ear to the inner ear is blocked or reduced. In other words, this particular form of hearing loss occurs when the cause of the hearing loss lies in the process of transferring sound from the outer ear through the middle ear to the cochlea, that is the hearing part in the inner ear. The degree of conductive hearing loss can vary, from mild to quite severe. Fortunately, most cases of this particular form of hearing loss can be improved.
Conductive hearing loss causes: Ear canal obstruction, eardrum hole & otosclerosis
The ears are made up of complex networks of ducts that work together to ensure successful hearing. Conductive hearing loss can occur if an ear structure, fluid, or foreign object prevents the outer or middle ear from transmitting sound waves to the inner ear. Common causes for this form of hearing loss include the ear canal being blocked by wax or a foreign object, a hole in the eardrum, and problems with three small bones in the ear called ossicles. Otosclerosis, which is an abnormal growth of the bones in the middle ear, can also cause this form of hearing loss.
Hearing loss causes: Cholesteatoma, presence of fluid, infections, structural defects in the ear & benign tumors
Cholesteatoma is also responsible for the occurrence of conductive hearing loss. This is a rare condition that manifests as an abnormal collection of skin cells behind the eardrum in the middle ear and mastoid process. If left untreated, it can damage the delicate structures inside the ear that are essential for hearing and balance. Other causes of conductive hearing loss include the presence of fluid usually due to allergies or a cold in the middle ear and more specifically in the space between the ear drum and the cochlea, the development of ear infections, the existence of structural defects in the outer or middle ear, or benign tumors.
Hearing loss symptoms
Having conductive hearing loss reduces the ability to hear at a normal hearing level. The symptoms of this particular form of hearing loss are therefore partial or complete hearing loss. Hearing loss can be in one ear or both ears. At the same time, an inability to hear silent sounds and a gradual loss of hearing are manifested. In the event that this form of hearing loss appears suddenly or the hearing decreases more and more in a short period of time, it is imperative to carry out diagnostic tests by a specialized otorhinolaryngologist. The present condition may be accompanied by dizziness, pain and a feeling of fullness in the ear, with a simultaneous fluid discharge.
Diagnosis of hearing loss
The diagnosis of conductive hearing loss, as well as the cause that caused it, is carried out by ENT Surgeon in Athens Dr. Olga Papadopoulou through a detailed history of the patient and by conducting a complete audiological evaluation. In particular, speech and tone audiometry as well as the control of auditory reflexes help significantly in the investigation of the condition. The main treatment options for conductive hearing loss are medication for infection, hearing aids or hearing implants, and surgery to correct the problem that caused it.
