Abstract

Dealing with laser-tissue interaction, it is essential to investigate both the morphology of laser- induced effects and the ablation rate. The conventional methods, like HE-stained histological sections, have various disadvantages as regards artifacts or spatial crater morphology assessment. A confocal laserscanning microscope was applied to investigate the laser effects of a Ho:YAG laser on bovine bone. With this instrument it is possible to scan the object both along the xy-plane and the z-axis, thus `optically cut' the specimen without damaging them, yielding exact crater profiles, 3D images, and crater volume calculations. In the delicate region of the skull base area it is of fundamental importance to know exactly which kind of affect will take place regarding both ablation rate and morphology.
