Title: Monteleukast Versus Inhaled Mometasone for Treatment of Otitis Media With Effusion in Children
Brief Summary: Otitis media is one of the most common infections among children and is a complication in about 30% of common colds. The most common complication of acute otitis media is otitis media with effusion. Some studies have reported the effects of montelukast and mometasone nasal spray in treatment of otitis media with effusion. However, current information is inadequate in this issue.
