[Problems of tracheotomy in locally invasive anaplastic thyroid cancer].

Between 1955-1985 515 patients with carcinoma of the thyroid have been operated. Among 170 cases with a local infiltration 69 tracheostomies were performed in 55% for lesions of both laryngeal nerves or intratracheal bleeding (absolute indication), in 45% as a prophylactic intraoperative procedure to avoid later death from asphyxiation (relative indication). In a retrospective study clinical results were analysed with special reference to the question whether patients profit by the tracheostomy. Follow-up examinations showed that tracheostomy did not influence the outcome of patients with a differentiated thyroid carcinoma while there was a remarkable difference in survival of patients with anaplastic tumors where those with a tracheostomy had a worse survival. In this group postoperative external radiotherapy often could not be administered or was delayed due to local complications of the tracheostoma.
