The “difficult thyroidectomies” (DT) are motivated by several factors that, alone or in association with each other, make surgery more laborious and increase the related risks.
Topographical, technical and anatomical criteria have been used by us to classify DT with a view to illustrating specific problems and suggesting appropriate strategies. According to topographical criteria we considered mediastinal goiter and resurgery; according to technical criteria we considered the presence of auto-immune thyroiditis and locally advanced malignancies; on the basis of anatomical criteria, we considered the presence of “non recurrent” laryngeal nerve and of a pre-operatory vocal cord palsy.
