[Dystopic goiter--aspects of definition and surgical therapy]

The incidence in the literature of dystopic goiter depends on classification of the false endothoracic goiter ("substernal goiter") as dystopic and varies from 2 to 20%. From November 1989 through April 1993 we operated on 530 patients with benign nodular goiters. In 84 patients (15.8%) the operation proved a dystopic goiter. We showed that difficulties in comparing our data with published series were due to misnomers of the dystopic goiter. The dystopic goiter comprises the true endothoracic goiters (alliata vera and isolata vera) as well as the false endothoracic goiters (substernal goiter). The precise classification of the dystopic goiter is crucial to an optimal operative strategy reducing postoperative morbidity.
