[Disorders of smell and taste. Standard and recent methods in diagnosis and therapy].

Compared to disorders of the ears and eyes, diseases of smell and taste seem to be far less outstanding: however, the unimpaired perception of odours and flavours comprises an important part of our well-being, as can be seen in the perfume industry or in drinking and eating habits. The ENT-specialist covers organic causes of these senses, as he has the tools to explore and treat in the depth of the nasal and oral cavities. The "Arbeitsgemeinchaft Olfaktologie/Gustologie der Deutschen Gesellschaft für Hals-Nasen-Ohrenheilkunde, Kopf- und Halschirurgie" therefore is in process of establishing a new set for a standardised smell and taste test, which is based in part on the sniffin'sticks, which were developed by Prof. Kobal, Erlangen. The examination procedure of nasal and oral chemosensory performance requires a high test-retest reliability and an efficiency comparable to internationally established measurements in order to render valid results in diagnostic and therapeutic procedures. The new test kit with the sniffin'sticks is presented in this paper, followed by an overview on some disorders of smell and taste perception and proposals for actual therapeutic procedures.
