[Anatomical study of the thyroid foramen in human larynx: a study of 100 dissections]

The foramen thyroideum was systematically studied on the specimen of larynx of 50 fresh corpses. Among the one hundred dissections performed, the foramen thyroideum was noted only in one specimen (2 foramen). It was symmetrical not only in the position but also in the diameter. In both of these cases, the foramen thyroideum always contains few vessels and nerves. It's possible physiological role and the origin of the contents of the foramen thyroideum are discussed based on the research literature.
