this technique is useful for lesions of the posterior third of the tongue for several reasons : 1 ) it provides excellent exposure , 2 ) it is cosmetically superior to most other approaches , 3 ) it allows for several alternatives to reconstruction , such as retrusion or rotation tongue flaps , 4 ) the procedure sustains minimum blood loss since the tongue is bisected in the midline in an avascular plane , ( 5 ) when preoperative radiation therapy has been included , this approach minimizes the amount of surgery performed through the radiated field , and 6 ) postoperative tongue mobility is usually sufficient to permit articulation and deglutition to approach normal .
