Yoo F, et al. - Via prospectively involving 35 adults with chronic rhinosinusitis (CRS) refractory to medical therapy, researchers assessed the impact of endoscopic sinus surgery (ESS) on the subjective and objective measures of cognitive dysfunction and related quality-of-life measures in CRS. Thirty-three out of 35 patients finished the survey satisfactorily. Data reported that postsurgical improvement in the Cognitive Failures Questionnaire was 46.7 ± 18.4 to 31.9 ± 17.8. In overall presenteeism, there has been a significant improvement. Polyp status analysis disclosed important improvements in mathematical processing and sample matching in only polyp-free CRS patients. Findings suggested an association of ESS with improvement in subjective and some aspects of objective cognition.
