Conductive Hearing Loss
Conductive hearing loss (CHL) occurs due to problems with sound transmission through the outer or middle ear. It typically originates in the middle ear and may have a variety of causes, including otitis media, an eardrum perforation, middle ear mass lesions such as cholesteatoma or ossicular chain abnormalities like otosclerosis. Ear canal problems can also cause CHL when they are severe. For example, complete cerumen impaction, aural atresia or stenosis and severe otitis externa cause CHL.
CHL may be temporary or permanent. After obtaining a thorough medical history, hearing is evaluated by comprehensive audiometry (hearing tests) including pure tone testing, speech audiometry and acoustic reflexes. Tympanometry may also be performed and depending on the clinical scenario, temporal bone imaging studies may be indicated. Treatment depends on possible causes (“differential diagnosis”) as well as the severity of the hearing loss. Surgery may be an option to improve hearing.
Why Choose Us
- Dr. 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. He is the first and most experienced Neurotologist recruited to Southern Arizona.
- Dr. Jacob was a founding member of the University of Arizona (UA) Department of Otolaryngology prior to his departure and transition to CNS. At UA, he was Vice Chair of ENT and held the rank of full Professor with Tenure. He was also founding Director of the UA Ear Institute.
- Dr. 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.
- Surgery designed to improve/restore hearing may be an option for some disease states, and an Otologist/Neurotologist like Dr. Jacob performing the procedure optimizes results. His specific training and experience in ear surgery – implantable hearing technologies, ear drum/ear canal reconstructions and manipulation of the ossicular chain (hearing bones) – minimizes complications and maximizes benefit. A full array of aural rehabilitation technologies is also offered, including state-of-the-art hearing aids for those electing to forego surgery.
- Our highly-skilled Doctors of Audiology, Stephanie Bourn, AuD, CCC-A and Mary Rose Goldstein, AuD, CCC-A, strive to provide you with accurate information regarding your hearing status, promote understanding of your hearing and communication needs, increase your knowledge of evidence-based management and/or treatment options, and introduce you to the hearing health tools that can maximize your quality of life reducing the negative impact of hearing disorders.
