简介：AbstractBackground and objective:Sinus surgery has seen significant changes over the years with advancements in instruments, endoscopes and imaging. This study aimed to use Hospital Episode Statistics (HES) data to review the total number of sinus related procedures performed in both adults and children across England and identify whether there were any trends across the study period. We predicted an increase in endoscopic sinus procedures with a decline in open approaches to the paranasal sinuses.Methods:Data from HES was extracted for the years 2010-2019. The operative (OPCS-4) codes relevant to all sinus procedures between E12.1 and E17.9 were analysed. After examination of overall sinus related procedures, further subgroup analysis was performed with regards to open or endoscopic techniques.Results:The total number of sinus procedures performed between 2010 and 2019 was 89,495. There was an increase in endoscopic surgeries by 21.1% and a decrease of open surgeries 35.3% during this time. There was an overall increase in maxillary, frontal and sphenoid sinus procedures, with a decrease in ethmoid sinus and lateral rhinotomy operations. There was an increase in the proportion of endoscopic cases overall by 5.7% and for all sinuses individually.Conclusion:Overall, we see an increase in sinus surgery over the last 9 years from 2010 to 2019. These findings are in keeping with our initial hypotheses. Although our data set is limited by coding, and lack of patient factors, it represents most, if not all, of the data in England over a large study period. It is therefore useful to add to previous studies when demonstrating the increasing popularity of endoscopic sinus surgery over open procedures.
