A REVIEW OF CASES OF ENDOSCOPIC SINUS SURGERY

Abstract

　Objective: To identify the clinical profile of patients who underwent endoscopic sinus surgery, and of cases of chronic rhinosinusitis with/without asthma at our hospital (Saku city, Nagano prefecture, Japan).

　Method: A retrospective study of 627 patients (1,038 sides) who underwent endoscopic sinus surgery from September 29, 2009 to July 1, 2015.

　Results: Chronic sinusitis (81.0%) was the most commonly encountered disease, and nasal obstruction (43.8%) was the most commonly encountered symptom in the patients who had undergone endoscopic sinus surgery. Pansinus surgery (61.8%) was the most commonly performed, while deviatomy was performed in a total of 70.5% of the patients. A navigation system was used in 9.9%, emergency operation was performed in 1.4%, sight disorders were present in 1.5%, and complications of the operation occurred in 1.4% of all patients. Of the patients with chronic sinusitis, 17.0% had asthma. In the patients with asthma, nasal obstruction (59.7%) and dysosmia (24.7%) were significantly more likely to be present, opacities in all sinuses on CT images were significantly more likely to be found, bilateral surgery (96.1%) and pansinus surgery (86.1%) were significantly more likely to have been performed, and the number of cases of revision surgery was significantly greater (23.2%).

　Conclusions: Various data of cases of endoscopic sinus surgery from our hospital were revealed. Furthermore, we found that the symptom profile, CT findings and frequency/types of operation differed significantly between patients of chronic rhinosinusitis with asthma and those of chronic rhinosinusitis without asthma.
