    Default As SM progresses, the supraoccipial bone resorbs

    In a November 2012 UK study by a team of veteran CM/SM researchers of 12 cavalier King Charles spaniels with Chiari-like malformation, they found that all of these conditions increased over time: syrinx width, height of the foramen magnum, length of cerebellar herniation, and caudal cranial fossa volume. The increase in the volume of the cranial fossa may be due to resorption of the supraoccipital bone as syringomyelia progresses. They conclude: "We hypothesise that active resorption of the supraoccipital bone occurs due to pressure from the cerebellum. These findings have important implications for our understanding of the pathogenesis and variable natural clinical progression of CM and syringomyelia in CKCS."

    Please could someone translate!! I know foramen magnum and cerebellar herniation - is caudal cranial fossa volume dilated ventricles? And what is resorption and the supraoccipital bone?

    The supraoccipital bone is the bone covering the hind end of the skull. That is the bone in which the foramen magnum is located. The cranial fossa is the space within the hind end of the skull. It is the volume of space in which the cerebellum has, to be located.

    Resorption means that the supraoccipital bone gets thinner. The thinner the supraoccipital bone gets, the more volume the cranial fossa acquires.

    Rod you often post these research reports on different forums. I often wonder if you find the different reception that news of health studies receive illuminating?

    The reaction varies so much............ Intelligent questions here, sneering denial elsewhere.

    Sneering denials, you suggest? Well, the responses speak for themselves, I guess. But when I offer this information, I am not really looking for reactions; I'm trying to inform the readers.

    Having been through a quite nasty US presidential election campaign this year, I found that many people from each side could not understand why anybody would vote for the opponent. This was due to a lot of character assassination on behalf of one of the candidates -- the ultimate winner, in fact. The winner accused his opponent of literally hating anybody who was not white, male, heterosexual, and an income taxpayer. The winner's supporters -- largely non-white, female, non-heterosexual, and non-income-taxpaying voters -- believed the winner's accusations. The supporters of the opponent could not understand how anybody else would believe that character assassination. Both sides heard the same accusations, but one side believed them and the other side did not.

    So, nothing surprises me when I read the reactions to the new information I impart about cavaliers.
