Abstract: Upper respiratory tract infections (URIs) are the most common acute illnesses.
Among them, particularly important in childhood, is infectious rhinosinusitis (IRS), which can
increase the sensitivity of the respiratory tract to obligate and facultative allergens for a long
time. Their timely diagnosis and adequate therapy are crucial in reducing frequent morbidity
and the risk of complications, including those of the respiratory system. Although IRS is well
known in pediatric practice, this brief literature review aims to characterize and elucidate the
key pathogenetic units of IRS in childhood, standard and new methods of disease diagnosis as
a plan for better management of therapy and minimization of complications.
