[Occult sinusitis in childhood (author's transl)]

Occult sinusitis in childhood is a special form of chronic rhinosinusitis. The symptoms of chronic sinusitis are not clear in these patients, but the diagnosis can be confirmed both radiologically and endoscopically. Aetiologically, an immunoincompetence or mucoviscidosis should be remembered. As well as conservative measures, treatment by antral lavage or antrostomy is recommended.
