Abstrakt:	Background: The injection of local anesthetic into the skin is often the only memorable event described by the patient after dermatologic procedures. Objective: The authors compared the pain felt during injection of local anesthetic using a minimal needle insertion technique with a 30- or 33-gauge needle. Materials and Methods: Three hundred eighteen patients with tumors on the head and neck were injected with lidocaine using a previously described technique with either a 30- or 33-gauge needle. After injection, patients were surveyed using the visual assessment scale for pain. Results: Seventy-seven percent of patients felt no pain with injection on the face using a 33-gauge needle compared with 64% with a 30 gauge, whereas 94% of patients felt no pain on the scalp with a 33-gauge needle compared with 54% with a 30 gauge. Visual analog scale scores were also significantly decreased on the face and scalp using the smaller needle. There was no difference in pain between the 2 needles with injection on the neck. Conclusion: This study further validates the use of this technique for the injection of lidocaine and the preference of a 33 gauge over a 30-gauge needle for the initial injection on the face and scalp.
