Although "optimum" conditions were present in the patients receiving beta-blocker, the authors thought that the grading system was not discriminating enough to demonstrate a significant difference between the groups. The crucial finding in the study was the correlation between heart rate and surgical grade in the entire group. During endoscopic sinus surgery surgery, anesthetic manipulations should be directed at maintaining a low heart rate.
Endoscopic endonasal skull base surgery is associated with a low level of patient-reported post-operative nasal morbidity. There is no significant difference in frequency of crusting, blockage, pain or discharge between pituitary and other anterior skull base pathology groups. However, anterior skull base surgery would appear to be associated with an increased rate of anosmia post-operatively.
High-volume low-pressure saline irrigation is recommended as an efficacious, easy to use and well-tolerated adjunct to endoscopic sinonasal toilet in the early postoperative period following functional endoscopic sinus surgery.
Based on the available evidence, nasoseptal flap (NSF) elevation with or without use in reconstruction likely leads to impairment in objective olfactory function. Endoscopic sellar and parasellar surgery without the elevation of an NSF may lead to a transient reduction in olfactory function. In the absence of a high a priori risk of cerebrospinal fluid (CSF) leak, it is an option to avoid routine NSF elevation in sellar and parasellar procedures, with preservation of at least 1 vascular pedicle during the approach. Monopolar electrocautery for mucosal incisions may increase the risk of olfactory impairment. If an NSF is used, donor site defect reconstruction may be considered.
Among a diverse sample of rhinologists (raters), there was substantial to almost perfect agreement between raters, and among individual raters at different timepoints. The IFAC is a reliable tool for classification of cells in the frontal sinus. Further outcome studies are still needed to determine the validity of the IFAC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
