Paper Abstract

A laser has been developed with the aim of being a microsurgical tool for ear surgery. Its emission at 2.7 - 2.8 μm is readily absorbed by water in tissue. This makes it ideal for ablation of the stapes, while minimizing transmission to the inner ear. Slices of porcine otic capsule bone to represent the stapes were ablated with the laser. The mechanical stress imparted to the stapes during ablation was measured using a piezoelectric film. The Er:YAG laser has similar optical properties, but this laser offers the possibility of a more compact surgical tool.
