Cervical approach for large thyroid mass with substernal extension

The large thyroid mass with substernal extension often requires a combination of cervical and thoracic approach for its access and removal. We have developed a technique that uses a cervical incision and combines clear access to the mass with low morbidity. The principle features include complete sternocleidomastoid mobilization, early identification of the neurovascular pedicle through a lateral approach, and finger dissection to deliver the substernal component of the mass. This article also describes the elements of our technique in detail, from preoperative considerations through wound closure and discusses the debate concerning the ideal treatment of these challenging tumors.
