Abstract
It is generally known that chemotherapy and radiotherapy are not so effective to thyroid carcinoma, so surgical resection of the tumor should be a main treatment.
Thyroid carcinoma sometimes invades the upper respiratory tract, such as larynx and/or trachea. In such cases the resection of a part of the respiratory tract and its subsequent reconstraction are necessitated.
Recently we experienced two cases of thyroid carcinoma which invaded the upper respiratory tract. After the resection we reconstructed the trachea with D-P flap and cervical flap. They had a fine clinical course.
There are several techniques for reconstructing the upper respiratory tract, but we recommend to use skin or myocutaneous flaps considering the safety and the accuracy.
