Implantation using rigid interstitial needles is an excellent treatment for small carcinomas that are confined to the anterior floor of mouth; it provides a high rate of local control. However, the needles must be inserted through the non-involved tongue in order to stabilize needle position. Even the most experienced operator has difficulty performing an implant which maintains proper spacing, and some inhomogeneity must be expected. Bone complications are experienced frequently even with early lesions, and the anterior one-third of the tongue is irradiated needlessly. Thirteen patients have received implants with an individually custom designed aluminum holder which holds the needles in a fixed position. Homogeneity of dose is improved, and the location of needles relative to the gingiva can be tailored to the lesion. It is not necessary to pierce the tongue. Operative trauma is minimized, and patient discomfort is less than with former techniques. The entire implant is completed in an instant with minimal exposure. Details of design and construction are presented.
