[Surgical treatment of intrathoracic goitre].

The definition by Katlic gives the best description of intrathoracic goitre, a condition that includes a small sub-group (1-4%) of patients with multinodular goitre who generally have severe compression symptoms and require specialised care in reference centres. The pre-operative study must include thoracic imaging techniques to plan the most suitable action. Total thyroidectomy is recommended, and in more than 95% of cases the goitre can be removed using a cervical approach. A wide cervical approach and the identification of the recurrent nerve near the cricothyroid joint help to free the thyroid from all its cervical attachments before gently retracting it upwards from the thoracic component for its removal. Intrathoracic goitres that require a sternotomy for its removal are recurrent goitres, those that have advanced cancer, those that reach the carina, and left posterior goitres that extend to the right pleural cavity.
