Although primary acquired NLD obstruction seems to be an ophthalmologic problem, rhinologic problems have great importance in etiology. Detailed endoscopic examination and preoperative paranasal sinus computed tomography will reveal the possible role of nasal and paranasal structures adjacent to lacrimal sac in etiology of NLD obstruction. This will be effective both on conservative treatment and postoperative success in patients scheduled for surgery.
Our findings suggest that PCOS and menopause induce significant histopathologic changes in the soft palate and base of tongue that are similar to the histopathologic changes seen in the soft palate and base of tongue of patients with obstructive sleep apnea syndrome.
Laryngeal manifestations due to estrogen deficiency have been studied in the literature. But to date, the possible histopathological changes of laryngeal mucosa due to estrogen deficiency have not been studied. Therefore, our objective was to determine the histopathological changes of laryngeal mucosa in ovariectomised rats in order to clarify effects of estrogen deficiency on laryngeal tissue. The study is a randomized trial and was conducted at the animal care facility of Haydarpasa Numune Education and Research Hospital. Twenty-one Wistar rats were used throughout the experiment. There were six rats in the sham-operated control group. And others were divided into two groups (4, 8 weeks) according to follow-up time after ovariectomy. We observed significant changes 4 weeks after ovariectomy when we assessed subepithelial edema, inflammation, cilia and goblet cell loss (p < 0.01). It was shown that estrogen deficiency after ovariectomy in rats caused changes in laryngeal tissue when it was studied histopathologically.
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.
