Skin incisions within the scope of nose operations

Some nose operations require an incision to be made through the nasal columella so that the cartilaginous and bony nasal pyramid can be exposed during the operation. The red marking in the picture frames the scar in the area of the nasal columella.
Within the scope of a reductive nose operation, additional incisions in the area of the nasal wings may be required in order to refine the latter.
