These cells convert incoming sound waves into electrical signals that are then shuttled to the brain. We will help our patients to understand their condition, listen to their concerns, answer their questions, and provide the best clinical treatment available.The most common type of hearing loss, called sensorineural, often stems from damage to the tiny hair cells that line the inner ear. Our physicians’ goal is to provide the highest-quality neurological care– the same level of care we would want for ourselves or our loved ones. To schedule an appointment with our Ear & Hearing department, please call us at (520) 795-7750. Otology/Neurotology and Audiology work together to offer complete hearing health solutions. Our Otologist/Neurotologist specializes in the medical and surgical care of patients with disorders of the ear and lateral skull base. A digital external amplification system, programmed by an audiologist, is required. VORP transforms sound into mechanical energy that is directly transferred to the middle ear bones, round window, or oval window. VORP (Vibrating Ossicular Prosthesis), which is a middle ear implant, is a third option. Such implants deliver sound directly to the cochlea by way of bone conduction, by-passing the external ear completely. An alternative approach in patients with normal or near-normal inner ear function is the use of bone anchored hearing implants (BAHI). The goals of that operation are to restore the external auditory canal to its normal size and improve sound conduction. Based on imaging results, some patients may be candidates for canalplasty (atresia repair). First, a high-resolution temporal bone CT scan is obtained to determine extent of external and middle ear development. Jacob offers several surgical options to treat auditory canal atresia/stenosis. Jacob transitioned his practice to the Center for Neurosciences in early 2017 as he felt that the new environment helped to optimize delivery of personalized ear and lateral skull base care. At UA, he was Vice Chair of ENT and held the rank of full Professor with Tenure. Jacob was a founding member of the University of Arizona (UA) Department of Otolaryngology prior to his departure and transition to CNS. He is the first and most experienced Neurotologist recruited to Southern Arizona. Abraham Jacob, Medical Director for Ear & Hearing (E&H) at the Center for Neurosciences (CNS), is fellowship trained in Otology, Neurotology, and Cranial Base Surgery. Acquired stenosis is unusual but is usually associated with infection, chronic inflammation, trauma, radiation therapy, or poor ear canal healing after surgery. Congenital atresia/stenosis may be associated with several different syndromes, including Treacher Collins, Goldenhar, Klippel-Feil, Branchio-Oto-Renal (BOR), and Hemifacial Microsomia. Therefore, temporal bone imaging studies may be required to ensure that this is not happening.Īuditory canal atresia is congenital (present at birth) while stenosis can be congenital or acquired. Patients with auditory canal stenosis are at high risk for ear canal cholesteatoma formation. This can also be associated with external and middle ear malformations. The inner ears and auditory nerves may be normal.Īuditory canal stenosis refers to narrowing of the ear canal(s). Patients with atresia often have other developmental abnormalities of the external ear and middle ear, resulting in conductive hearing loss – hearing loss that arises from abnormal transmission of sound through the outer and/or middle ear. One ear is typically affected, but both ears can be atretic. It is often associated with microtia (a poorly developed outer ear). Intensity Modulated Radiation Therapy (IMRT)Īuditory canal atresia is a developmental absence of the external auditory canal.Physician Assistants & Nurse Practitioners.
