Official Title: Influence of Regional Anaesthesia on the Expression of Substance P During Neck Dissection Due to Oropharyngeal Cancer
Brief Summary: In the clinical trial the investigators will observe the impact of regional anesthesia in addition to a general anesthesia on the expression of substance P in patients with unilateral oropharynx carcinoma undergoing bilateral Neck Dissection. The investigators will perform an unilateral regional cervical plexus block on the tumor side and a sham blockade on the contralateral side. The tissue of the tumor side and of the contralateral side will be analysed by immunohistology, measuring the expression of the Substance P.
