We assessed the changes in olfaction and mucociliary transport after functional endoscopic sinus surgery (FESS) in 80 patients with chronic paranasal sinusitis. Olfaction was evaluated with the butanol threshold test and mucociliary transport was assessed by saccharin transit time (STT). Postoperative butanol threshold scores were significantly reduced (p < 0.01), and the changes were more profound in severer forms of paranasal sinusitis as graded by ostiomeatal-unit computed tomography. The mean preoperative STT (27 min) which was significantly longer than that of controls (12 min) was significantly reduced 1, 6 and 12 months following FESS (p < 0.01). The results suggest that impairment of olfaction and mucociliary transport in chronic paranasal sinusitis may be significantly improved following FESS.
A prospective study was performed to evaluate the effects of adenotonsillar hypertrophy on snoring in children. Thirty male patients were grouped with respect to the severity of snoring and were evaluated in terms of the noise level of the snoring sound, the lowest arterial oxygen saturation, degree of palatine tonsillar hypertrophy, body mass index and cephalometric findings that included the adenoidal-nasopharyngeal ratio, the angle between the lines sella turcica/nasion and most posterior point of anterior maxilla/nasion, the angle between the lines sella turcica/nasion and most posterior point of anterior mandible/nasion, the posterior airway space, the distance from the sella to the nasion, lower face height and the distance from the basion to the posterior nasal spine. The noise level of the snoring sound, the lowest arterial oxygen saturation and the adenoidal-nasopharyngeal ratio showed a significant correlation with the severity of snoring, but the degree of palatine tonsillar hypertrophy and the body mass index failed to disclose any significant relationship.
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.
