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.
