Answer :
Final answer:
Hearing loss as a complication of bacterial meningitis in infants can depend on various factors including the bacterial strain, severity of the infection, promptness of treatment, and individual patient factors. While bacterial meningitis can lead to sensorineural hearing loss, effective and timely treatment can improve the prognosis. Correct option is C.
Explanation:
Regarding the question, "Is hearing loss a permanent complication of bacterial meningitis in infants?" the most accurate answer would be c) Depends on the bacterial strain. Although not exclusively determined by the bacterial strain, the risk of permanent hearing loss varies and can also depend on other factors, such as the timeliness and effectiveness of treatment, the severity of the infection, and individual patient factors.
Bacterial meningitis can indeed lead to serious and sometimes permanent complications, including hearing loss. This condition is known for causing inflammation of the membranes surrounding the brain and spinal cord, which can subsequently affect the nerves related to hearing. The severity of the infection and how quickly it is treated are critical factors. For example, patients who receive prompt and effective antibiotic treatment, like Hannah in the provided scenario, may have a better prognosis and may avoid long-term effects.
Additionally, there are different types of hearing loss, including conductive hearing loss and sensorineural hearing loss, with the latter often being more likely in the context of meningitis. Sensorineural hearing loss results from damage to the auditory nerve or the cilia in the inner ear, whereas conductive hearing loss stems from physical blockages or damage to the outer or middle ear structures.
