Surgical approach to thyroid nodules and cancer.
Fine needle aspiration cytology is the mainstay of the diagnostic work-up of solitary thyroid nodules. Together with the patient's history and the clinical findings, cytology determines the indication for surgery. The minimal intervention for a suspicious nodule consists of thyroid lobectomy. If a diagnosis of malignancy is established, then we recommend total thyroidectomy for all follicular lesions that are larger than 1.5 cm and for high-risk papillary tumours. Near-total thyroidectomy may be appropriate for low-risk patients with papillary carcinoma in whom it is not intended to use radioactive iodine ablation. Whereas ipsilateral lymphadenectomy of the central (primary) compartment should routinely be performed, modified radical neck dissection is only indicated in evident nodal disease of the lateral (secondary) compartment(s). Patients with incidentally discovered differentiated thyroid carcinomas generally do not require complete thyroidectomy unless the tumours are larger than 1.5 cm in diameter or nodal involvement is present. A detailed description of the surgical technique for thyroidectomy and lymphadenectomy is given and an overview of surgical complications is provided.
