**1. Introduction**

Frontal bone (FB) fractures are found in about 12% of craniomaxillofacial trauma patients. [1, 2] They are more strongly associated with concomitant brain injuries than other facial fractures, which is the reflection of the amount of energy required to produce a fracture in this region. Recently, increase in the incidence of FB fractures was reported, while the incidence of fractures of other facial sites decreased. [3] This increase in frontal bone fractures (FBFs) incidence may be related to the emergence of causes other than road traffic accidents (RTAs), especially all terrain vehicle (ATV) accidents. The aims of FBF treatment are restoration of facial appearance, restoration of skull integrity and protection of brain, and prevention of late complications. The most important factor in management of FBF is involvement of frontal sinus (FS). Despite the relative frequency of FS injuries, there is no general consensus about their optimal management and numerous treatment algorithms were published during the recent years. The purpose of this chapter is to provide an overview of advances in surgical management of traumatized FS and to share our experience with this type of injury.
