Upper mediastinum involvement in diseases of the head and neck may require a sternal split. This study describes our adaptation of the upper median or "minimal" sternotomy technique for the treatment of head and neck pathologies. Between April 2002 and October 2005, 17 patients aged 4 to 82 years underwent minimal sternotomy in our institution for a variety of head and neck pathologies. The 17 patients included 11 adults with metastatic thyroid disease (six metastatic papillary thyroid carcinoma, two medullary carcinoma, and one Hiirthle cell carcinoma) and huge retrosternal goiter (n = 2), four adults with parathyroid disease (two primary parathyroid adenoma, one secondary hyperplasia, and one parathyroid carcinoma), and two children with lymphangioma and huge thymic cyst (one each). Average hospitalization was 8 days. Four patients needed a thoracic drain for 2 days, one had recurrent laryngeal nerve palsy, and one had phrenic nerve paresis. There were no postoperative deaths. Minimal sternotomy appears to be an excellent alternative for surgical exploration of the mediastinum and may be used in head and neck surgery for a range of indications.
