Photoablation of bone by excimer laser radiation.

Background And Objectives: The aim of the present study was to compare the usefulness of mechanical osteotomy tools and common laser systems with the ultraviolet (UV) laser in the field of the central nervous system and its bony capsule.

Study Design/materials And Methods: The cranial bones of 42 living rats were treated with UV laser radiation with wavelengths of 193 nm and 248 nm. The morphology and physical effects were evaluated by means of optical and scanning electron microscopy.
