Ryu, Kwon, Koh, Lee, Cho, and Kim: Changes in Clinical Characteristics of the Patients Who Received Endoscopic Sinus Surgery according to 10 Year Temporal Difference: A Retrospective Observational Study

Abstract

Background and Objectives

Endoscopic sinus surgery (ESS) was introduced to Korea in the 1980s and has since developed rapidly. There have been many changes in ESS over this period. Thus, in this paper, we explore trends in the clinical characteristics of ESS.

Subjects and Method

We retrospectively reviewed patients who underwent the ESS at 000 Hospital performed by a single surgeon at a 10-year interval. By comparing 106 patients who underwent ESS in 2003 and 108 patients who underwent ESS in 2013, we investigated changes in ESS in terms of the target group of surgical indications, CT scores, range of operation and complications.

Results

With regard to surgical indications, the proportion of patients who underwent surgery due to nasal polyps in 2013 (32.4%) was lower than in 2003 (59.4%), while the proportion of patients undergoing fungal sinusitis surgery in 2013 (13.9%) was higher than in 2003 (0.0%). In terms of preoperative CT evaluation, Lund-Mackay scores for the maxillary sinus, ethmoid sinus, and ostiomeatal unit were lower in 2013 than in 2003. The proportion of ESS performed only in the maxillary sinus in 2013 (20.0%) was higher than in 2003 (10.0%).

Conclusion

According to this study, the range and extent of sinusitis was favorable in 2013 compared to in 2003. The group of patients requiring treatment for only maxillary sinus disease accounted for a larger proportion of patients in 2013 than in 2003.
