Rhinoplasty may be performed under various depths of anesthesia including local anesthesia, intravenous sedation (also called IV sedation, twilight anesthesia or MAC anesthesia) and general anesthesia. Each option has its advantages and disadvantages depending on cost, safety, awareness and side effects.
IV Sedation
Although many surgeons prefer IV sedation for rhinoplasty, this is not the best anesthetic approach. It mostly relies upon the skillful dosing of powerful anesthetics through an intravenous catheter. The main point is that the anesthesiologist must be very skilled to achieve the right dose of anesthetic, since in many instances the patient may stay conscious to some extent. On the other hand, if too much anesthetic is administered, the patient stops breathing.
In case of IV sedation the airways are not protected by a breathing tube and blood can be inhaled into the lung, leading to serious complications.
Although IV sedation is less expensive than general anesthesia, the risks, discomfort and effectiveness of it make it less preferable than general anesthesia.
General Anesthesia
Because nose surgery is comparatively non-invasive, the patient only requires enough anesthetic to render them entirely unconscious. Longer surgical cases are far better tolerated and the airway is protected from aspiration by the presence of a breathing tube.
The after-effects of general anesthesia are generally mild and short-term. And because respiration is maintained by a ventilator, the depth of anesthesia can be adjusted to keep blood pressure low and thus minimize bruising, swelling, and bleeding.
Perhaps the biggest reason against the use of general anesthesia is the fear of post-operative nausea and vomiting which may dramatically elevate blood pressure levels leading to much heavier facial bruising, swelling, and discomfort.
In addition, the technical benefits of general anesthesia translate into better cosmetic outcome for the patient with fewer anesthesia-related risks or side effects.
