Unilateral Choanal Atresia: Indications of Long-Term Olfactory Deficits and Volumetric Brain Changes Postsurgically

xlomafota13 shared this article with you from Inoreader Unilateral Choanal Atresia: Indications of Long-Term Olfactory Deficits and Volumetric Brain Changes Postsurgically Via O.R.L. Journal for oto-rhino-laryngology and its borderlands Background: Very few studies have investigated whether unilateral choanal atresia is associated with permanent olfactory deficits. Objective: This study aimed to evaluate the olfactory performance of patients with unilateral choanal atresia postsurgically. Methods: Three patients with unilateral atresia were examined in terms of olfactory performance with the Sniffin' Sticks test (odor identification, threshold, and discrimination), size of the olfactory bulb, and volumetric brain changes. Results: All p atients demonstrated significantly lower olfactory performance in terms of odor threshold on the same side with the choanal atresia. Grey matter reductions were found ipsilaterally in the hippocampus. Conclusions: This pilot study indicates that persistent olfactory deficits and volumetric brain changes are present in patients with unilateral choanal atresia. ORL View on the web Inoreader.
