A Prospective, Randomized Controlled, Single-Blinded Study to Assess the Effect of a 33-Gauge Needle Versus a 34-Gauge Needle on Pain Experienced During Injection of Local Anesthetic on the Face

Background: Most pain experienced by patients during Mohs micrographic surgery is associated with the initial injection. Previous studies have shown that a smaller gauge needle (33-gauge vs 30-gauge) is associated with less patient-reported pain.
