Abstract
- Endoscopic resection with post-operative radiotherapy has been included in the standard therapeutic options for olfactory neuroblastomas (ONBs). Recent publications have indicated the feasibility of olfactory preservation after endoscopic unilateral resection of ONBs. This study validated residual olfaction using the psychophysical assessment, T & T olfactometer, in patients who underwent endoscopic unilateral resection with post-operative radiotherapy. A single-institutional retrospective review was performed to identify patients who underwent endoscopic unilateral resection of ONBs with olfaction monitoring using T & T olfactometer between 2009 and 2020. T & T olfactometry was performed before surgery, after surgery, before radiotherapy, and after completion of radiotherapy. Four patients (one female and three males) were identified. The mean observation period was 41.9 months, and all patients showed no evidence of disease. Three patients exhibited residual olfactory function with two patients having normal or pre-operative level olfaction, although T & T olfactometer results showed a temporary increase in recognition thresholds after surgery. As consequence, endoscopic unilateral resection can achieve satisfactory olfactory preservation in patients with early-stage ONBs.<br />Competing Interests: Declaration of Competing Interest There are no conflicts of interests in this study. This study was approved by the Ethics Committee of Kyoto University Hospital (R-2805).<br /> (Copyright © 2021. Published by Elsevier B.V.)
