Sensorineural Hearing Loss - Differential Diagnosis Algorithm



Asymmetric Sensorineural Hearing Loss: 

 • Neoplastic (Vestibular Schwannoma)

 • Retrocochlear Tumor

 • Iatrogenic (Radiation, Surgery)

 • Idiopathic Unilateral Sensorineural Hearing Loss

Symmetric Congenital:

 - Hereditary:

    • Mondini dysplasia

     • Atresia

 - Non-hereditary:

     • Developing Cochlear Insults: CMV, Rubella, Toxoplasmosis, HIV, Syphilis, Hepatitis

     • Teratogenic drugs, Alcohol

Symmetric Neurogenic (Central):

 • Infection (Meningitis)

 • Cardiovascular Ischemia

 • Multiple Sclerosis

Symmetric Cochlear (Inner-Ear):

 • Presbycusis

 • Loud Noise/ Trauma

 • Cochleitis

 • Ototoxic Drugs (Oral Aminoglycosides, etc.)

 • Meniere's Disease

 • Autoimmune (Cogan's Syndrome)
