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.
The exact cause of otosclerosis is unknown. It may be passed down through families. People who have otosclerosis have an abnormal sponge-like bone growing in the middle ear. This growth prevents the ear bones from vibrating in response to sound waves. These vibrations are needed in order for you to hear. Otosclerosis is the most common cause of middle ear hearing loss in young adults. It typically begins in early to mid-adulthood. It is more common in women than in men. The condition may affect one or both ears. Risks for this condition include pregnancy and a family history of hearing loss.
