The General Anesthesia Paradigm
Historically, facial surgery was synonymous with general anesthesia: intubation, complete operating room, hospitalization, anesthetic risks. This created a real barrier for many patients who wanted rejuvenation but feared — with reason — the risks of general anesthesia. The evolution of surgical techniques, especially those with minimal dissection and well-defined planes, allows a different approach: local anesthesia with conscious sedation.
“If the surgical technique is elegant enough not to require endoscopic vision, it can also be elegant enough not to require general anesthesia.”
- — Dr. Robério Brandão
Local Anesthesia + Sedation vs General Anesthesia
Aspect Local + Sedation General Anesthesia
Consciousness Sedated but responsive Unconscious
Airway Spontaneous breathing Intubation/mask
Recovery 30-60 minutes 2-4 hours
Hospitalization Outpatient Frequent overnight
Nausea/vomiting Rare Common (20-30%)
Cost Lower Higher
Risks Lower Higher
Tumescent Technique for Face
Tumescent anesthesia, popularized in liposuction, was adapted for facial surgery:
Typical Tumescent Solution
- • Normal saline: 500-1000ml (vehicle)
- • Lidocaine: 0.05-0.1% (anesthetic)
- • Epinephrine: 1:500,000-1:1,000,000 (vasoconstriction)
- • Bicarbonate: 10mEq/L (buffering - reduces burning)
Advantages of Tumescent Technique
Hemostasis: Epinephrine causes vasoconstriction, reducing bleeding
Hydrodissection: Volume helps separate anatomical planes
Prolonged analgesia: Effect lasts 4-8 hours
Structure protection: “Pushes away” nerves and vessels
Patient Selection
✅ Good Candidates
- • Controlled/mild anxiety
- • No allergy to local anesthetics
- • Moderate duration procedures (<4h)
- • Preference to avoid general anesthesia
- • ASA I-II (low anesthetic risk)
- • Motivation for outpatient procedure
❌ Prefer General Anesthesia
- • Severe anxiety/phobia
- • Documented allergy to lidocaine
- • Very extensive procedures
- • Need for uncomfortable positions
- • Comorbidities requiring invasive monitoring
- • Patient’s expressed preference
Modern Face Protocol
Preoperative
Oral anxiolytic (alprazolam or similar) 1h before. Calm environment, music if desired. 2.
Monitoring
Oximetry, BP, ECG. IV access for sedation and emergencies. 3.
Initial Sedation
Midazolam + fentanyl IV in titrated doses. Goal: relaxed but responsive patient. 4.
Infiltration
Tumescent solution infiltrated slowly. Wait 10-15 minutes for vasoconstrictor effect. 5.
Procedure
Surgery with sedation reinforcement as needed. Communication with patient maintained. 6.
Postoperative
Recovery in appropriate room. Discharge with companion after outpatient discharge criteria.
