لماذا يمنع الانتثار أو النف بقوة أثناء الاصابة بالرشح أو الزكام

 لماذا يمنع الانتثار أو النف بقوة أثناء الاصابة بالرشح أو الزكام:

والسبب أنه أثناء الاصابة بالزكام يكون الأنف ممتلئ بالمفرزات الحاوية على الفيروسات والباكتيريا , وكما نعلم فان الاذن تتصل مع البلعوم الانفي والأنف عبر قناة اوستاش (اوستاكي) وبالتالي فعند الانتثار بقوة ترتد المفرزان من الانف عبر قناة اوستاش لتدخل الى الاذن وتسبب التهاب اذن وسطى -  فغالبية حالات التهاب الاذن الوسطى الحاد تأتي بعد نوبة زكام أو رشح
