Sheehan Nasal Chisel | Fine Nasal Chisel for Rhinoplasty

Professional Sheehan Nasal Chisel for Accurate Skeletal Refinement

Achieving a smooth dorsal profile or performing precise lateral osteotomies requires the reliable performance of the Sheehan Nasal Chisel. This 16.0cm instrument is widely recognized as a Fine Nasal Chisel due to its balanced weight and thin blade profile, which allows for precise bone cutting with minimal structural vibration. Offered in tip widths ranging from 7mm to 12mm, this Flat nasal chisel provides surgeons with the versatility needed to manage different bone densities and anatomical widths. Adas Instruments manufactures the Sheehan Nasal Chisel from high-quality stainless steel, ensuring a passivated surface that supports atraumatic tissue management and resists the corrosive effects of repeated sterilization in high-volume surgical environments.
