New experimental neurosurgical technologies of delayed cranioplasty after large bone-flap craniotomy

Purpose: to develop measures of craniotomy for convenience and efficiency of delayed cranioplasty improving.Methods. A new method of delayed cranioplasty after large bone-flap craniotomy in rats was described using extra- and intracorporeal maintaining of the bone graft after removing a large portion (50%) of the scull cap and placing shims between dura mater and lamina vitrea and between dura mater and galea aponeurotica m. occipitofrontalis in the projection of the wound.Results. Complete restoration of the anatomic integrity of the bones of the skull cap was observed, there was no rough adhesions of soft tissue.Conclusions. The proposed technique allows to perform safe, efficient and convenient for the surgeon large bone-flap craniotomy followed low-impact delayed cranioplasty.
