Abstract
Craniomaxillofacial (CMF) trauma surgery is a challenging field due to the unique anatomy and the wide variety of injuries in head and neck region Frontal sinus fractures represent 5 to 15% of all facial fractures and are most often the result of high velocity craniofacial trauma, such as motor vehicle collisions Frontal sinus fractures should be suspected in all patients presenting with trauma to the upper face. The examination involves a thorough palpation of the supraorbital ridge, glabella, and soft tissue of the lower forehead. In the acute setting, swelling may obscure examination findings The gold standard in diagnosis and classification of frontal sinus fractures is a computed tomography (CT) scan of the face, head, and neck. Reconstruction of CT images in both axial and sagittal orientations is often helpful In the late 1980s, computer aided design (CAD) and virtual surgical planning (YSP) were introduced using three-dimensional (3D) imaging data in Computed tomography (CT) to produce prosthesis (5) This has created innovative options for fabricating new patient specific implant (PSI) to achieve better outcome (6). The need for digital planning before surgery is increasing and nowadays it has the upper hand in accuracy and perfect contouring of CMF surgery (7).
