**3. Clinical manifestations**

Aside from mild conductive hearing loss, OME does not cause any other symptoms of dis‐ comfort and is therefore easily overlooked. In infants, OME combined with hearing loss may continue for weeks or even months without being detected. A child with OME may also suf‐ fer poor sleep quality [15]. Parents of children with CLP should pay particular attention to how their children interact with others and how they react to sound. If any abnormality is observed, the child should undergo expert evaluation. More importantly, children should visit an otolaryngologist for a regular otologic examination to ascertain whether they are suf‐ fering from OME. Early diagnosis and treatment are invaluable in preventing or alleviating future hearing loss.
