<abstract xmlns="http://www.w3.org/1999/xhtml"> BACKGROUND.

We performed a retrospective clinical study about the incidence of the pneumatization of crista galli in 196 patients with chronic sinusitis.

Pneumatization of crista galli was found in 30.1% of cases. From 59 patients with chronic rhinosinusitis and pneumatized crista galli, 66.4% had no opacification, 23.7% various degrees of opacification and 11.9% showed complete opacification.
