Then, all bone fragments are separated and removed. Formed mucoperiostal flap is placed in 0.9 % NaCl solution. Remaining fragments of bones of cells of latticed labyrinth, preserved sections of paper plate and areas of remaining periorbite are removed. It is followed by resection of the section of paraorbital cellulitis by the microdetbreader under strict vision control in order to prevent traumatisation of the medial muscle of the eye. Free mucoperiosteal flap is laid in the projection of the paper plate so that the entire surface of paraorbital cellulitis is covered with the flap. Transplant is mobilized with haemostatic tampon.
