The authors report two cases of high cervical spinal chordomas that were removed via the median labiomandibular glossotomy(MLG) approach. One patient was a 62-year-old female in whom an extradural chordoma was found at the level of C3 vertebra with huge prevertebral extension, and causing dyspnea and dysphagia; the other was a 47-year-old female, found to be suffering from a chordoma of C2 vertebral body, which was found incidentally. After removal of the tumors, ventral instrumented fusions were performed in both patients, who showed good recoveries with only minor complications. The MLG approach is radical, and rarely performed by neurosurgeons, but for treatment of an expanded high cervical lesion that needs ventral surgery and seems to be inaccessible via the conventional transoropharyngeal or anterolateral retropharyngeal route, it should be considered. The authors discuss the clinicopathological characteristics of spinal chordomas and general considerations of the MLG approach to high cervical lesions, and briefly describe the surgical techniques involved in this approach.
Key Words: High cervical lesion; Median labiomandibular glossotomy; Spinal chordoma; Clinicopathological characteristics
