Nasal gouges allow the separation of mucous membrane from the bony septal base. They can also be used for opening a window in the lacrimal bone to expose the sac. This helps in restoring the tear flow into the nose. Here are some of the types:

•    Freer Septum Gouge
•    West Bone Gouge

This tool is autoclavable and can withstand environmental changes. It can be reused after proper cleaning and sterilization.
