High-Performance Passow Ear Chisels for Refined Otological Surgery
The Passow Ear Chisels are essential for otologists performing delicate canalplasty and middle ear procedures where precision in bone removal is the highest priority. Functioning as a high-precision bone dissector, this instrument features a micro-tapered blade that allows the surgeon to shave away thin layers of cortical bone with extreme accuracy. Adas Instruments ensures that each Passow pattern surgical chisel is forged from premium steel, providing the necessary rigidity to handle controlled mallet impact without obstructing the surgeon’s view under the microscope. We ship USA, Europe & worldwide via DHL, FedEx, and UPS to deliver German steel instruments that meet the rigorous demands of microscopic temporal bone surgery.
