[Differential diagnosis of salivary gland swellings (excluding neoplasms)--the ORL view (author's transl)].

Important investigatory methods for the diagnosis of non-neoplastic salivary gland disease are discussed.

Chronic recurrent parotitis is presented as an example of the difficulties in differential diagnosis and treatment.
