[Closure of defects of the dura mater using flaps of autologous periosteum]

The author has used for closure of the defects of dura mater the periosteal flaps on a pedicle. Such a flap is mobilized in the operative wound, its careful sewing to the dura mater provides hermetization of the subdural space, its size is not limited, it can stretch, providing in necessity brain decompression. The tender adhesions are forming between the periosteal flap and underlying brain. The method was successfully used in 49 patients. No complications were noted. A shortcoming of the method consists in the fact that it can be used only in resective cranial trepanation.
