Laryngeal carcinoma can metastasize to many locations among which the neck is the most frequent. In this case report, a 53-year-old patient who was diagnosed with laryngeal carcinoma underwent total laryngectomy, total thyroidectomy and right radical neck dissection. Contralateral neck dissection was planned for 3 weeks later. On the third post-operative week, the patient developed VI and VII cranial nerve paralysis. The patient was given palliative chemoradiotherapy. However, 1 year after the primary diagnosis and 3 months after the cavernous sinus metastasis, he died. Despite the fact that the metastasis of the laryngeal carcinoma to the cavernous sinus is very rare, it has a very unfavourable prognosis.
