[Plastic surgery of the frontonasal anastomosis using a hydroxyapatite prosthesis].

The authors offer a method of plastic reconstruction of the frontonasal anastomosis after radical surgery on the frontal sinus. The prosthesis made of hydrooxyappatite ceramics is established in the anastomosis created during radical surgery without additional fixation. Due to special biological properties of the material, the prosthesis firmly consolidates with bone walls of the anastomosis warranting reliable drainage and aeration of the frontal sinus.
