Facial Blocks with Dr. Erica Westlake, PGY2

Why use facial blocks?

  • Indications include: laceration repair, acute migraine headaches, zoster outbreaks
  • Improved cosmetic healing with regional block compared to infiltrative anesthesia 
  • Block provides longer duration of anesthesia compared to infiltrative anesthesia 

How do you perform facial blocks?

  • The supraorbital, infraorbital and mental foramen should align with a line drawn vertically through the ipsilateral centered pupil 
  • Assess neurovascular status prior to anesthesia especially with trauma 
  • Massage area of anesthesia to assist with distribution 
  • Complications include: bleeding, hematoma, infection, incomplete anesthesia, vascular puncture, nerve injury, systemic local anesthetic toxicity, ocular injury

Branch of frontal nerve which continues superiorly 

Branch of frontal nerve which continues medially 
-Supraorbital foramen is 2 cm laterally from nasal aspect of orbital rim-Block both the supraorbital and supratrochlear nerve by directing the needle first cephalad and then medially toward nasal spine
InfraorbitalBranch of maxillary nerve which continues medially and caudally -Infraorbital foramen is below the orbital rim at intersection of pupil and nasal alae
-Intraoral approach: inject into the buccal mucosa at canine and direct upward and outward
-Extraoral approach: laterally approach foramen until bone is hit, inject local anesthetic 
Mental Branch of mandibular (alveolar) nerve which continues medially -Mental foramen in line with premolar tooth
-Intraoral approach: retract lower lip and insert needle into mucosa of first premolar tooth, inject down and outward 
Extraoral approach: approach foramen laterally
