Thyroidectomy consists of the partial or total removal of the thyroid gland, an endocrine gland (which produces hormones) located in the antero-inferior and middle part of the neck. This intervention can have several purposes: - specify the nature of one or more nodules detected in the thyroid. - remove all or part of the gland due to malfunction, not controlled by medical treatment. - remove all or part of the gland due to its size and the risk of compression of neighboring structures - prevent the occurrence of cancer in the event of a proven genetic risk (family background of multiple endocrine neoplasia)
