title: [The use of glass fiber endoscopy in afterloading contact therapy].
abstract: In afterloading contact therapy of cervico-facial tumors the control of position of the applicator has a special importance. Especially this applies the contact therapy in epipharynx. By means of a phantom of synthetic material the application can be simulated in epipharynx and the position of the applicator can be shown by means of computer-assisted tomography in all three planes. Estimation of distances by computer-assisted tomography allows correction in position and also control of corrected applicator position. Compared to it the glass fibre endoscopy requires longer working time and the topographical orientation is rendered more difficult with the technique being available in the same manner as post-rhinoscopic endo-photographic documentation of findings.
