Repair of dural defects in awkward areas-technical note.
Dural tears located at the base of the skull are difficult to repair due to the difficulties in the appropriate access and the fragility of the dura in such areas. In our experience the biggest problem when attempting to perform a dural repair in a deep narrow field is not to place the stitches, but rather to set the knots. A newly designed, easy-to-learn technique has been developed for dural closure in these situations. We present here a new technique for dural suturing of special interest when the space available is limited. In our hands it is possible to obtain a watertight dural closure in most microsurgical operations performed through a small hole and/or into a narrow, deep surgical field. These techniques can also be applied during a secondary procedure following development of a postoperative CSF leak. While simple and easy to learn, these techniques require practice in the laboratory setting before clinical application.
