A non-looping afterloading technique for base of tongue implants: results in the first 20 patients.
The results of treatment in the first 20 patients treated by a non-looping afterloading technique for base of tongue implant are described. Ten patients had carcinoma recurrent in the base of tongue after previous treatment and they were treated by implant alone. The other 10 patients had previously untreated carcinoma of the base of tongue and they were treated with a combination of interstitial implant, external radiation therapy and surgery. The minimum follow-up is 1 year and maximum 5 years. No local or regional failures have occurred in the previously untreated patients. No local failures have occurred in the previously treated patients who had lesions up to 4 cm in diameter, but three out of four patients with recurrent lesions larger than 4 cm have failed locally. Two patients developed necrosis related to the implant; the factors responsible for this are discussed.
