Warning

The common name for |Structure of pharyngotympanic tube (body structure)| is eustachian tube.  While the term originated eponymously, it is not the name of the person from whom the body structure was named after.  Therefore, the case significance is ci for case insensitive. 

Extensions

SNOMED CT includes three case significance values, "ci", "cI" and "CS". However, this range of values depends on the languages and linguistic norms. For the International Edition, where the first character of descriptions is always capitalized, the value "Only initial character case insensitive" ("cI") is necessary. This value is not required for descriptions in extensions that do not adhere to this convention. When appropriate, it is also acceptable to limit the range to a single case significance value.

Numeric values

Numeric values will not display differently if switched between upper and lower case, so numeric values should be treated as case insensitive characters in a term.
