Post-operative Pain: An audit of patient reported pain scores after
endoscopic and microscopic ear surgery
Abstract
Objectives The aim of this study was to compare patient reported pain
scores and analgesia requirements between endoscopic and microscopic ear
surgery. Design Prospective cohort study Setting Secondary care setting
from June 2017 to December 2020. Participants Patients undergoing ear
surgery performed by a single surgeon. Main outcome measures The primary
outcome measure was patient reported pain as recorded by a visual
analogue scale (VAS) at days 1,2,3 and 7 post-operatively. Secondary
outcome measure was post-operative analgesia requirement. Results
Overall, forty-nine patients encompassing 65.3 % (32/49) endoscopic and
34.7% (17/49) microscopic procedures were audited. Endoscopic
procedures have statistically significant lower VAS pain threshold
outcomes when compared against the microscopic procedures on post-
operative day one (endoscopic group median VAS 1.5 [0.00;11.5] mm
versus microscopic group median VAS 27.0 [15.0;65.0] mm); to day
seven (endoscopic group median VAS 0.5 [0.00;2.75] mm versus
microscopic group median VAS 9.00 [2.00;52.0] mm). Requirement for
analgesia was greater in the microscopic group at day one compared to
the endoscopic group (64.5 %, 20/31 endoscopic group vs. 100 %, 17/17
microscopic; p= 0.004). Conclusion Endoscopic ear surgery is less
painful and requires less analgesia in the initial post-operative period
than microscopic surgery in this cohort. The overall results of this
study are useful for pre-operative patient counselling and pain
management in the clinical setting. Given the differing applications of
microscopic and endoscopic ear surgery, further research is required to
study the influence of bone removal, type of operation, and incision
type on pain after ear surgery.
