Final answer:
Chronic Suppurative Otitis Media (CSOM) is a persistent or recurrent ear infection causing a perforated eardrum and discharge, often following an acute otitis media infection. It commonly affects children due to anatomical factors and is caused by bacteria such as Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis.
Step-by-step explanation:
Chronic Suppurative Otitis Media (CSOM) is a condition characterized by recurrent or persistent ear infections that result in tearing or perforation of the eardrum, coupled with persistent discharge from the ear (otorrhea). This condition can lead to serious complications such as hearing loss, bone erosion, and further infections. The condition tends to occur following acute otitis media (AOM), when the infection persists beyond a short period, and the ear continues to drain pus or fluid for more than a couple of weeks.
AOM typically occurs due to obstruction of the eustachian tubes, which promotes fluid accumulation in the middle ear, creating an environment susceptible to bacterial growth. This is particularly common in younger children due to anatomical and behavioral factors such as shorter eustachian tubes and frequent upper respiratory infections. Bacterial pathogens like Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis are common culprits involved in AOM infections, which can potentially lead to CSOM if not effectively treated.
