Repair of the NOSE or modification of its shape by operation performed by reconstructive and ENT (ear, nose and throat) surgeons. It may involve alteration of the bony skeleton of the nose and/or alteration of the SEPTUM (septorhinoplasty). It is mostly performed for cosmetic reasons; however, any disease process or injury which has caused a defect in the nose may be repaired as well. The latter problem would usually involve the utilisation of some form of skin flap, whereas this would not be required for cosmetic surgical purposes.
