Every person (especially a child), even rarely ill, needs to visit an ENT doctor at least once a year. It is important to identify the causes of nasal congestion, poor hearing, and headache, and not just eliminate the symptoms. Often, when examined, foreign bodies are found in children, and in adults – often remnants of cotton wool, sulfur plugs and other "finds". They are eliminated by rinsing the external auditory canal with warm water from a syringe.
