Rhinoplasty for dorsal hump and over projection: a standard rhinoplasty involves shaving down the dorsal hump reducing the projection of the nose particularly the tip, and may involve lifting of a hanging columella, refining a tip, and tucking wide nostrils. These things can theoretically be done under sedation, and were typically done that way a few decades ago. However very few surges Would do it that way today. Sedation leaves the surgeon without control of the airway which could lead to aspiration and a potentially disastrous outcome. Most surgeons can also perform their best work when the patient is comfortably asleep and not reacting to their work. Bear in mind that when the nasal Dorsum is shaved down , This is followed by in fracturing of the bones to close the roof and narrow the width of the new bridge. This would be quite gory for the patient to undergo awake, Or just sedated. Heavy sedation to get around this dulls the gag reflexes and can lead to aspiration as mentioned above. General anesthesia for relatively young healthy people for this type of surgery is extremely safe, and the incidence of catastrophic complications would be extremely low in good hands and in a good facility.
