[New type of combined surgical treatment of frontobasal injuries (author's transl)].

The surgical treatment of frontobasal injuries by a new, combined method has been reported. The frontobasal injury was exposed by bifrontal craniotomy. After the intradural examination and the dressing of the brain injuries the dural defect was also extradurally searched and dressed. Thereafter--taking the advantage of the bifrontal exploration--the paranasal sinus (frontal sinus, ethmoideal system) was cleaned, then the base of the anterior scala was covered with pedicled galea flap or periosteum plate. In case of the treatment of the open injuries, following the removal of the bone fragments, the dural brain injuries and the paranasal sinus injuries were similarly treated, according to the above mentioned principles. This method makes possible to prevent the liquorrhoeic complications as well as the delayed septic complications of the paranasal sinus. The method is recommended to the operative treating of the frontobasal injuries after many years of favourable experiences and supported by good follow-up results.
