The operation is usually a same-day surgery done withgeneral anesthesia.
It typically lasts one to three hours.
There are no exterior cuts as the surgery is performed through the nostrils.

Verywell / Laura Porter
Most patients go home the same day as their surgery.
Regardless of which pop in of anesthesia you will have, septoplasty is usually done as an outpatient surgery.
When you have local or general anesthesia, you should plan to have someone drive you home afterward.
Call 911 if you are experiencing a medical emergency.
What to Wear
There are no specific clothing requirements for septoplasty.
You should leave jewelry at home, and it’s a good idea toremove piercingsbefore surgery.
This includes quitting smoking.
Smoking can inhibit your body’s immune system and delay healing after surgery.
A Word From Verywell
Many people have a deviated, or crooked, septum.
When this abnormality causes problems with breathing, you and your doctor may decide that septoplasty surgery is appropriate.
Talk to your doctor about surgical options and how to prepare.
Surgery is usually over in a few hours, and you’re able to go home that day.
