INTRODUCTION: Cancer in the tongue base, which is adjacent to or invading the lingual epiglottis, requires resection of part or all of the larynx to assure adequate surgical margin. Based on whole mount laryngeal sections, a tongue base-partial supraglottic laryngectomy procedure was designed for tumors adjacent to or minimally invading the lingual epiglottis.
METHODS: A group of five patients with carcinoma of the tongue base adjacent to or minimally invading the lingual epiglottis was identified. This technique requires excision of the epiglottis, hyoepiglottic ligament, and pre-epiglottic space with the lesion. The structural physiological integrity of the false vocal cords with or without the hyoid bone is preserved.
RESULTS: Clear tumor margins were obtained in all five patients. In three patients who required up to 50% resection of the tongue base, decannulation and resumption of a full oral diet was achieved. Two patients with more extensive lesions required 70% resection of the tongue base. Both patients underwent completion laryngectomy months later because of persistent aspiration.
CONCLUSION: This preliminary report suggests that partial supraglottic laryngectomy may be used with acceptable functional results in patients with limited tongue base lesions.
