Reconstruction of the tongue after glossectomy is a primary objective in the process of improving the life quality of patients suffering from tongue cancer. We developed a new method of surgical reconstruction of the tongue after hemiglossectomy, with reinnervated rectus abdominis musculoperitoneal flaps. The rectus abdominis musculoperitoneal flap consisted of the rectus muscle, posterior rectus sheath, peritoneum, the 10th, 11th and 12th intercostal nerves, and the deep inferior epigastric artery and veins. Five patients underwent immediate reconstruction of the tongue with rectus abdominis musculoperitoneal flaps after hemiglossectomy. The intercostal nerves were anastomosed to the descending branch of the hypoglossal nerve. All transplanted flaps survived. The peritoneum was replaced by squamous epithelium eight weeks after surgery. During the follow-up period, the contour and function of the reconstructed tongues was satisfactory. Our experience indicates that reconstruction of the tongue with rectus abdominis musculoperitoneal flaps after hemiglossectomy is a suitable, cosmetically acceptable method.
