Osteomyelitis of Frontal Bone Resulting From Extension of Suppuration of Frontal Sinus: Surgical Treatment

The development of unsightly scars as a result of improper management of suppurative frontal sinusitis and osteomyelitis of the frontal bone1and the development of abscesses2of the brain as a result of inadequate treatment of these two conditions have prompted us to employ the surgical procedure presented here. It is obvious that early drainage of a suppurating frontal sinus will preclude extension of the infection to the frontal bone and the brain. Although the infection is usually attributable to Staphylococcus pyogenes-aureus, it may be extremely virulent and involve the diploic channels and the emissary veins of the skull within forty-eight hours. Therefore, the procedure we present is advantageous in preventing the usual deformity that follows an operation on the frontal sinus and permits the removal of all sequestrums and thorough drainage of the frontal sinus by removing the posterior table of the sinus.
