A nasofrontal hernia is the most common displacement of the cerebral cortex through the anterior cranial fossa into the nose. The hernia is located in the anterior part of the central fossa of the frontal part of the brain, localized mainly on both sides of the midline - Kraepelin's point. It is more often observed in women (up to 40 years of age), as well as in middle-aged people and children, as a complication of traumatic brain injury. Men get sick less often.
The sliding of the cerebral cortex along the peduncles reaches the midline, shifting to the caudal (i.e., posterior) part of the nasal cavity. In some cases, a sliding cord covered with the meninges passes through the nasal cavity from the outside to the inside and ends up in the cranial cavity, exerting a mechanical effect on the soft tissues.
!__Classification!___ _**Hernia**_ **cranial** **nasofrontal** is divided: 1) depending on the cause that caused the development; 2) from the location of the brain; 3) from the localization of hernial masses; 4) on the depth of the brain. **Based on their origin, hernias are classified as follows:** 1. Primary, occurring when there is a violation in the area of the aponeurosis. 2. Secondary, develop as a consequence of other diseases at the level of the skull. If we go into detailed division, the classification will be quite extensive.
