Tongue implants: discussion of some dose-time-volume parameters and afterloading techniques.
Detailed computerized calculations of 28 radium tongue implants permit the conclusion that dose-time adjustment especially when geometry is poor, increases the chance of recurrence. The overdosage volume in the vicinity of the needles could be calculated and is small. Because of greater adaptability of afterloading iridium techniques and better results according to others, our patients are now treated with a combination of external beam treatment and iridium implant.
