A medical instrument for reducing or reconstructing fractured or congenitally and posttraumatically deformed facial bones three dimensionally is disclosed. The above medical instrument tightly attaches to a human head outside the skin in order to reduce or reconstruct a fractured or deformed facial bone. The medical instrument thus neither requires complex surgical operations nor the use of foreign substances during the reduction or reconstruction of the fractured or deformed facial bones. Therefore, the medical instrument leaves no scar on the skin, causes neither infection nor ill effects due to the existence of foreign substances. The instrument comprises means (1) for tightly attaching the instrument to a cranial bone (51) said attaching means (1) being screwed to a mastoid area of temporal bone (52) of cranium; means (3) for holding displaced bone segments of a fractured or deformed facial bone thus reducing or reconstructing the facial bone, said holding means (3) being screwed to the displaced bone segments in order to hold the bone segments in their original places thus reducing or reconstructing the facial bone three dimensionally; and means (2) for connecting the attaching and holding means (1, 3) together and adjusting the position of said holding means (3) in order to arrange the holding means (3) on the skin above the bone segments of the facial bone. |
