Of all complications in aural infection, thrombophlebitis of the sigmoid portion of the lateral sinus is most frequent. Trauma sustained in surgical treatment is a factor in the causation of morbidity and mortality. A device that lessens surgical trauma in the treatment of sinus thrombosis should prove useful.
The sinus plugs ordinarily used at present to block off the sigmoid sinus at the torcular and the jugular ends cause a great deal of trauma when they are removed. These plugs must necessarily be removed en masse. Adhesions are torn apart and granulations are crushed; this causes a variable amount of bleeding. The bleeding is at times so marked that the otologist is in doubt that the sealing off of the sinus is complete and repacks it. Indeed, the fibrous adhesions binding the walls of the sinus may be torn by the squeeze as the plugs are pulled toward the incision.
