The discontinuity in the head occurs either in the skin and meat or in the bone. In bone, this can be either exposure, crushing, displacement, or injury to the overlying skin. This type of injury includes a fungus, in which the brain membrane protrudes, swells, becomes fat and becomes mushroom-like.
This also includes injury to the meninges and injury to the brain itself; the latter is dangerous. With injuries that reach the membrane of the brain, relaxation occurs on the side of the wound and spasm on the opposite side. If the incision does not reach the ventricle and only reaches the border of the thin membrane, then this is more successful, but if the wound reaches the brain, then fever and vomiting of bile appear; survive only in rare cases. The closest thing to success with such a wound is when it affects both anterior ventricles, if you quickly take action and close it. Injury to both posterior ventricles is more severe, and injury to the middle part of the brain is even more severe than injury to its posterior part, and it is more difficult to return the patient to a natural state; this is only possible if the wound is small and insignificant and measures to close it and heal it are taken quickly.
Treatment in general consists of taking measures as quickly as possible to prevent the tumor using means that are permissible in this case. As for the details of this, we mention the treatment of cut wounds of the skin and flesh, speaking of ulcers, in Book Four, and the treatment of skull fractures in the paragraphs on fractures and repositioning of bones.
Regarding fractures of the skull with a break in the bone, that is, with its confusion, there are two schools among doctors: the school of those who are inclined to use calm, motionless drugs with strong analgesic properties, and another school that advises the use of strongly drying drugs. After cutting off the debris, removing the torn pieces and extracting the fragments with the help of pulling medicines-plasters and others, they put an ointment of vinegar and honey on top of the sore spot.
Healing with the hands of these new doctors is achieved more often than with the hands of the ancients, and this is not at all surprising. Galen says: Verily, the nature of the membrane of the brain and bones is dry.
