Tornwaldt's cyst is an uncommon type ofnasop haryngeal cyst that ma y cause clinically significant symp toms. We reviewed reports of 31,855 com p uted tom ograph y (CT) scans and 21,158 magnetic resonance imaging (M Rl) scans to ascertain ho w man y Tornwaldt 's cys ts were dis covered incidentally. These images had been obtained betw een Jan.
Postoperative complications of sinus surgery include bleeding, infection, and synechiae. Improved subjective outcomes in humans treated with fibrin sealant (FS) after endoscopic sinus surgery (ESS) have been reported. Streptococcus pneumoniae was used to initiate chronic sinusitis in occluded rabbit sinuses in order to evaluate the role of FS in mucosal healing. Six weeks later, all animals had maxillary antrostomies. Homologous FS-containing ciprofloxicin (100 mg/mL) and clindamycin (15 mg/mL) was applied topically to treatment rabbits (n = 9). Control rabbits (n = 10) received no antibiotics. Two weeks into the recovery phase after antrostomies, all animals were re-examined. Mucociliary transport velocity (mean +/- standard deviation in mm/minute) was measured in all sinuses (n = 38) during healthy (100% measurable, 13.82 +/- 4.16), infected (18% measurable, 4.74 +/- 0.42), and recovery phases (5% measurable, 6.30 +/- 4.67). In both groups, mucopurulent discharge was present in the majority of sinuses (control group 18/20, FS group 16/18). In addition, there was no significant difference in the recovery phase between the two groups when comparing changes in the size of antrostomies, light microscopy, or culture clearance. Scanning electron microscopy did suggest a possible improvement in ciliary regeneration in the FS group. Application of FS-containing antibiotics did not appear to improve healing after ESS in our rabbit model of chronic sinusitis.
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.
