Comparing Numbing Techniques in Mohs Micrographic Surgery

Summary

This study seeks to determine whether adjunct regional nerve blocks reduce pain and anxiety in adult patients undergoing Mohs micrographic surgery for face and scalp skin cancers. Participants will be randomized to one of two arms: (1) placebo regional nerve block with sterile normal saline or (2) adjunct regional nerve block with lidocaine. All patients receive local infiltration with lidocaine for complete anesthesia.

* Ability to complete patient reported outcome measures in English.

Exclusion Criteria:

* Known allergy or contraindication to lidocaine or epinephrine.
* Chronic opioid use or pre existing pain disorders that may interfere with pain reporting.
* Presence of scar tissue at the anatomic site of local infiltration or nerve block that may alter anesthetic penetration.
