Does anyone know this? I'm sure the thin, delicate eardrum itself isn't bleeding, right? So when someone suffers a ruptured eardrum, whether from infection or trauma, where is the blood actually coming from? I don't get it!
Hi Stephanie, A ruptured Eardrum is going to bleed. Whilst the Eardrum is very thin (about 0.1mm), it is covered with a thin layer of skin and does carry a blood supply. Think of inside your nose, its kinda like a much thinner version of your septum. Hope this helps Al
No mystery here....
Yes, the blood comes from the eardrum. It has small blood vessels through which it received its nourishment. The eardrum has 3 layers, a middle fibrous layer, a middle ear mucosal layer, and an external layer of squamous epithelium (similar to skin but much thinner). The fibrous layer is the thickest.
In the case of trauma, such as from use of Q tips, it is more common for the thin skin of the ear canal to be the source of bleeding, although puncture of the eardrum is also seen less frequently than canal trauma.
