[Partial sternectomy for metastatic tumor with reconstruction using a methylmethacrylate plate].
A case of partial sternectomy for metastatic thyroid carcinoma is reported. En bloc excision was followed by reconstruction using a molded plate of methylmethacrylate. Sternal tumours are rare and operations for cure of metastases are justified only if the general condition of the patient permits and in the patient with a single metastasis whose primary cancer operation was a radical one. Extensive en bloc excision is based on preoperative investigation in which computerized axial tomography has an important place in delineating the extent of the tumour and providing accurate knowledge of the margins of the section. Reconstruction with methyl-methacrylate allows a rigid setting with a material that can be molded, is radiolucent, inert and well tolerated. In the upper sternum it contributes to the stability of the shoulder girdle and protects the underlying mediastinal structures in a cosmetically acceptable way.
