Cranioplasty with Palacos R in reconstruction of frontal sinus defects.

The use of methylmetacrylates has not been widely accepted for the repair of frontal bony defects due to the possibility of secondary infection. The development of a new type of methylmetacrylates into which antibiotics, such as gentamicin, are incorporated has reduced the risk of secondary infection. The surgical technique and the results are illustrated on three patients. Favourable results were obtained in small and in large bony defects and even after previous frontal osteomyelitis.
