How safe is rasping the bridge under local anesthesia?

Under local anesthesia when done correctly a minor dorsal hump can be filed down.  Although there is still some bleeding that can be associated.many doctors perform rhinoplasties under local anesthesia and do great work.   The patient must be cooperative as well. Ask yourself, how well do you do at the dentist when they are treating a cavity and assess for yourself how you think you can handle itregards

Its really difficult to comment on this without photos. In general any type of rasping of the nasal dorsum can be uncomfortable without adequate local anesthesia. I could see this being done for a slight amount of post-traumatic or post-surgical scar tissue. Without more history or photographs it is hard to make further assumptions.
