Which age group is most susceptible to developing sinusitis?

School-aged children are particularly susceptible to developing sinusitis due to several factors. At this age, children often experience frequent upper respiratory infections, which can lead to inflammation and obstruction of the sinus passages. Their immune systems are still developing, making them vulnerable to viruses and bacteria that contribute to sinus infections.

Additionally, the anatomical differences in young children, such as smaller and more horizontally oriented sinuses, can also predispose them to sinusitis. As they grow, their sinus cavities develop and change, which may reduce the frequency of sinusitis. In contrast, while infants and adults can also develop sinusitis, the prevalence and susceptibility are generally seen to be higher in the school-aged population due to the reasons mentioned above. Teenagers typically have fewer infections compared to younger children, as their immune systems are more mature.
