Authoritarian regimes are also sometimes subcategorized by whether they are personalistic or populist. Personalistic authoritarian regimes are characterized by arbitrary rule and authority exercised mainly through patronage networks and coercion rather than through institutitions and formal rules..
Common causes of conductive hearing loss include: 1  Cerumen (earwax) or foreign body in the external auditory canal. 2  Otitis externa, infection or irritation of the outer ear.  Exostoses, abnormal growth of bone within the ear canal.
Different parts of the hearing pathway can be affected, and loss is classified as conductive, sensorineural, or mixed, depending on the part of the pathway that is affected. Conductive hearing loss occurs when something blocks sound from reaching the sensory structures in the inner ear. The problem may involve the external ear canal, the eardrum (tympanic membraneâTM), or the middle ear.
