Which of the following factors is associated with recurrent otitis media?

• A. Smoking exposure
• B. Regular pacifier use
• C. Drinking from a bottle while lying down
• D. All of the above

Answer: (D)

Recurrent otitis media happens more often when the environment and feeding practices promote dysfunction and inflammation of the middle-ear drainage pathway. Exposure to cigarette smoke irritates the nasal passages and the Eustachian tube, leading to inflammation and impaired clearance of secretions, which makes infections more likely and recurrent. Regular pacifier use is linked to a higher risk of ear infections in children, possibly because it alters swallowing patterns and keeps the Eustachian tube in a less ventilated state for longer periods. Drinking from a bottle while lying down allows milk to pool toward the Eustachian tube, which can irritate the middle ear and provide a medium for bacteria, increasing infection risk.

Because each of these factors can contribute to the pathway that leads to middle-ear infections, all of the above are associated with recurrent otitis media. Reducing smoke exposure, limiting prolonged pacifier use, and avoiding feeding in a supine position can help lower the risk.
