Abstract
Four patients with cervical cystic lymphangioma were treated in our clinic. Three patients were surgically treated. In 2 of these patients, tumors were completely removed. These tumors showed no invasion of the oral floor, parapharyngeal space or sphenopalatine fossa. A tumor in the third patient could not be completely resected. The tumor had invaded the oral floor, parapharyngeal space and sphenopalatine f ossa. In this patient, the volume of the remaining tumor was decreased postoperatively by local injection of OK-432. One patient did not undergo surgery, and was treated with local injection of OK-432 as the first choice. Since this therapy the tumor has not been palpable. These results suggest that local injection of OK-432 may be the first choice in place of surgical treatment for cases in which incomplete resection or postoperative complications are predicted.
