Median Labiomandibular Glossotomy의 치험례

Median labiomandibular glossotomy

Resection of the posterior part of oral cavity and oropharynx requires adequats exposure. Transoral approach provides limited access. The cheek splitting approach may leave a relativbely poor cosmetic result, and pull-through approach fails to provide better access. Some benign and malignant lesions of the posterior tongue and oropharynx may be approached through a median labiomandibular glossotomy(MLG) and excellent access to the upper anterior cervical spines and the clivus may be obtained by MLG. MLG technique not only provides maximum transverse and sagittal exposure, but considerably reduced operating distance. This technique is relatively anatomically sound and less complicative surgery, and can be routinely performed by oral and maxillofacial surgeons. Modifications of MLG are thought to be useful in the management of oral and oropharyngeal malignant tumors.
