Abstract

Abstract : Objective: To evaluate pain associated with laryngeal electromyography (LEMG). Study Design: A prospective case series. Methods: Adult patients scheduled for LEMG in a tertiary care laryngology practice were recruited between July 20, 2016, and March 1, 2017. Demographic and clinical data were extracted from the charts. Study participants reported their anticipated pain level using a visual analog scale (VAS) prior to the procedure. VAS was administered again within 10 minutes after the procedure, along with the validated McGill Pain Questionnaire, to gauge patient's pain perception after undergoing LEMG. Results: Results were reviewed for 80 patients (mean age 48.2 ± 16.6 years, 37.5% male). Preprocedure VAS pain scores (4.59 ± 2.3 out of 10) were not significantly different than postprocedure VAS pain scores (4.61 ± 2.4) ( P = 0.95). The McGill Pain Questionnaire reported a moderate pain level (32.1 ± 12.7 out of 78). Females anticipated a higher preprocedure VAS pain score (5.04 ± 2.3) than males (3.85 ± 2.2) ( P = 0.02); however, postprocedure scores were not significantly different between genders. The following factors did not influence the pain scores: age, professional voice use, history of previous EMG, chronic pain diagnosis, psychiatric diagnosis, or current treatment with pain/psychiatric medications. All LEMGs were completed without any complications. Conclusion: Patients appropriately anticipated their pain levels for the LEMG, which may be attributed to proper patient education and counselling before the procedure. Overall pain levels were mild to moderate, and all LEMGs were completed; thus, LEMG was well tolerated. Level of Evidence: 4. Laryngoscope, 128:896–900, 2018
