Objective: Descending goiter has been a focus of controversy in thyroid surgery until nowadays. This study aims to investigate the diagnosis and treatment options of thyroid goiters extending into the mediastinum and the thoracic cavity.
Methods and materials: A retrospective study was conducted assessing all cases of substernal goiter managed in a tertiary care referral center within 22 years. Demographics, clinical, operative, anatomical, and pathological data of the patients were recorded and analyzed.
Results: Among 3.028 total thyroidectomies, 212 procedures for substernal goiters were studied. All cases underwent total thyroidectomy. The surgical approach was cervical in all but two cases. A very low rate of complications and zero mortality were noted. Incidence of malignancy on permanent histology was 16%.
Conclusion: Descending goiter constitutes a major indication for thyroid surgery. The overwhelming majority of descending goiters may be managed surgically through a neck incision. In experienced hands good results with low morbidity should be expected. Such cases should be considered as challenging, however, and therefore management in a referral center may be necessary in order to ensure optimal results.
