[20-year experience in obliteration of the frontal sinuses with formalinized allobrephobone in chronic frontal sinusitis].

Outcomes of surgical treatment of chronic recurrent frontal sinusis (FS) using obliteration of the frontal sinuses with allobrephobone in 228 patients (190 males and 38 females aged 15-71 years) are presented. 45 of them had undergone surgery on the frontal sinuses with reestablishment of the frontonasal shunt. Obliteration consists in removal granulations and polyps from the frontal sinus through the anterior wall followed by sinus mucosa scraching and the sinus separation from the nasal cavity with filling with small pieces of formalized allobrephobone. The technique is simple, postoperative period usually uneventful.
