Porotic hyperostosis is a condition that affects the skull by creating a porous, sponge-like texture on the outer surface of the bone. It is most often seen near the top and sides of the cranium. This happens when the marrow spaces inside the skull expand, often as the body tries to produce more red blood cells. Over time, the outer layer of bone becomes thinner and pitted.#LearnOnTikTok #TikTokLearningCampaign #EduTok
