The question of salvage surgery involving the mandible has been discussed many times, especially today as we are in the era of the myocutaneous flap. However, it is universally accepted that the best mandibular reconstruction is to spare the mandible initially. We have seen that a marginal resection (rim resection) has been a good procedure for Tl-T2 and some T3 lesions of the anterior floor of the mouth. This is a procedure which does not leave external scars and lends itself quite readily to dental rehabilitation. Whether or not this procedure can be done effectively after preoperative irradiation or following radiation failure or recurrence has been of great interest. We have evaluated al1 of our cases that have been done with a minimum of two to fifteen years follow-up. The postop management has been carefully scrutinized and the question of teeth and dental therapy has been examined closely. Our experience encompasses eighty-five cases of which approximately onehalf have had radiation therapy. Our survival figures and also the functional and social rehabilitation of the patients leads US to believe that mandibular salvage surgery following irradiation is a good modality and should be in the anamentation of the surgical oncologist.
