Neue Methode der Zungenrekonstruktion mit neurovaskulären infrahyoidalen Muskelfaszienlappen

: Surgical treatment of tongue cancer can lead to extended defunctionalization, depending upon the size and localisation of the defect. Great problems of swallowing arise after total glossectomy or extensive resections of the base of the tongue even after reconstruction with myocutaneous island flaps or free flaps. We developed a neuromuscular island flap derived from the infrahyoidal musculature to reconstruct a total tongue or large defects of the tongue base. This fasciomuscular flap is formed by the M. sternothyroideus, M. sternohyoideus and the upper part of the M. omohyoideus. The axial blood supply arises from the A. thyroidea sup. The innervation is derived from the Ansa cervicalis N. hypoglossi. In case of total glossectomy we took this flap from both sides of the neck. With this new method we reconstructed total tongues after glossectomy in two patients and large defects of the tongue base in six patients. In the present paper the new surgical method and the functional results are described.
