👉 Macrocephalous is a term used in medicine and genetics to describe individuals with an unusually large head size. It refers to the extra volume of the skull, which can lead to issues such as headaches, difficulty breathing, and poor vision. Macrocephaly is often seen in patients who have undergone surgery or other medical procedures that cause the brain to expand, leading to a larger than average head size. Macrocephaly can also be caused by other factors such as genetics or environmental factors.
