Galea-Cranium Suture Method for Prevention of the Subcutaneous Fluid Collection —Technical Note—

Abstract

A simple method is described for preventing cerebrospinal fluid (CSF) from collecting in the subcutaneous space following a supratentorial osteoplastic craniotomy. A few pairs of oblique holes through which suture materials may pass are made by drilling in the surface cortex of the bone flap. The galea aponeurotica is sutured to the bone flap by means of these holes. These galea-cranium sutures reduce the subgaleal free space in which pooling of CSF or hematoma may occur.
