The nose corrective surgery is performed under general anaesthesia. It may be performed as a day case. You can therefore be discharged after a few hours.

There are two basic types of rhinoplasty depending on indication:

Closed rhinoplasty
In closed rhinoplasty the incision is entirely inside the nose. The procedure leaves no visible scars but the operating area is very restricted.

Open rhinoplasty
In open rhinoplasty the incisions in the skin of both nostrils are connected by an incision across the columella between the nostrils. The entire operating area can be accessed in this way. The scar in the skin under the nose is practically invisible after it has healed.

A nasal splint is applied to the nose post surgery for 1-2 weeks.
