Assessment of intraoperative pain during Mohs micrographic surgery (MMS): An opportunity for improved patient care

Abstract

Background: Intraoperative pain during Mohs micrographic surgery (MMS) has not been characterized. However, many patients report postoperative pain on the day of MMS.

Objective: We sought to determine if patients experience pain during their MMS visit.

Methods: In phase I of this study, patients were asked to report intraoperative pain level using the verbal numerical rating scale (0-10) at discharge. In phase II, pain levels were assessed before each Mohs layer and at discharge, to determine whether pain was experienced throughout the day.

Results: Pain was reported at some point during the MMS day for 32.8% of patients (n = 98). The mean pain number reported was 3.7 (range 1-8) out of 10. Pain was more commonly reported by patients who spent a longer time in the office, had 3 or more Mohs layers, and had a flap or graft repair. Patients most frequently reported pain with surgical sites of the periorbital area and nose.

Limitations: Time between Mohs layers was not measured. There was nonstandardized use of intraoperative local anesthesia volume and oral pain medications.

Conclusion: Some patients experience pain during MMS. However, the majority of patients report a low level of pain. Additional preventative measures could be considered in patients at higher risk.
