Background: Chronic rhinosinusitis (CRS) is a common condition that has been associated with cognitive dysfunction. The purpose of this study was to evaluate the effect of endoscopic sinus surgery (ESS) on the subjective and objective measures of cognitive dysfunction and related quality-of-life measures in CRS. Methods: Thirty-five adults with CRS refractory to medical therapy were prospectively enrolled. Preoperatively and postoperatively (≥4 months), subjects completed objective neurocognitive evaluation with the Automated Neuropsychological Assessment Metrics (ANAM) platform and multiple questionnaires, including the Cognitive Failures Questionnaire (CFQ), a modified World Health Organization Health and Work Performance Questionnaire (ctHPQ), 22-item Sino-Nasal Outcomes Test (SNOT-22), Sinus Control Test (SCT), Questionnaire of Olfactory Disorders (QOD), Beck Depression Inventory―second edition (BDI-II), Pittsburgh Sleep Quality Index (PSQI), and Fatigue Severity Scale (FSS). Results: Thirty-three of 35 patients satisfactorily completed the study. Postsurgical improvement in the CFQ was 46.7 ± 18.4 to 31.9 ± 17.8 (p < 0.001). Neurocognitive testing revealed significant improvements in mathematical processing (p = 0.003) and matching to sample (p = 0.023), as well as a significant decline in simple reaction time (p = 0.026). In addition, improvements were noted for SNOT-22 (54.8 ± 21.4 to 24.8 ± 21.1, p < 0.001), SCT (9.3 ± 2.6 to 3.9 ± 3.8, p < 0.001), PSQI (10.7 ± 4.5 to 6.9 ± 4.0, p < 0.001), BDI-II (14.0 ± 9.9 to 8.9 ± 9.0, p < 0.001), QOD (17.6 ± 13.4 to 9.9 ± 12.3, p = 0.001), and FSS (4.6 ± 1.4 to 3.1 ± 1.5, p < 0.001). There was significant improvement in overall presenteeism (7.3 ± 1.4 to 8.4 ± 1.3, p = 0.029). Analysis by polyp status revealed significant improvement in mathematical processing and matching to sample in only CRS patients without polyps. Conclusion: ESS is associated with improvement in subjective and some aspects of objective cognition.
