Ear canal stenosis treatment
Ear canal stenosis is a condition characterised by narrowing the external ear due to the increase of soft or bone tissues. This condition is usually noticeable to the person due to decreased sound perception. Usually, the stenosis can only be corrected surgically.
Stenosis is the narrowing of the external auditory passage over some distance. There is a distinction between congenital and later acquired auditory canal stenosis. They usually start from the cartilaginous part of the ear canal or the bony part.
Congenital narrowing of the canal is more often one-sided. It is combined with malformations of the cochlea, vestibule and a vestibule-cochlear nerve. Congenital ear stenosis is manifested by deafness from early childhood. It is either caused by congenital malformations or acquired (secondary) with persistent otitis externa, trauma (surgical or non-surgical), malignant neoplasms or irradiation.
The leading causes of acquired auditory canal stenosis are inflammation and tumours. But shrinking scars after surgical operation or exostoses can also trigger the condition. In addition, there are cases of the development of ear canal stenosis after prolonged use of drops of boric alcohol. In some of these conditions, stenosis is formed by the thickening of the subcutaneous tissue.
Identification of ear canal stenosis is based on comorbidities signs. Chronic otorrhea, which is not treated by medications, often occurs. In some cases, this is hearing loss, although it is not a characteristic feature. Patients complain about noise in the ear, ear congestion, and hearing loss. When pus is retained in the middle ear, they have a fever, pain, and a feeling of heaviness in the head. On examination, there is a narrowing of the external auditory canal. Therefore, the ENT doctor conducts a thorough otoscopy and microscopic examination of the ear canal.
If there are indications for surgery, the doctor should additionally prescribe a computed tomography of the ear. It allows the surgeon to determine thickness and areas of narrowing and see the location of major nerves and vessels. For example, it is crucial to understand the location of the facial nerve to prevent its damage during ear surgery.
