“…About 4% of the population does not have frontal sinuses and other 4 to 5% have only small rudimentary air cells (Aydinlioǧlu et al, 2003; Pondé et al, 2003; Kalavrezos, 2004; Montovani et al, 2006). Normally developed frontal sinuses are usually about 28–30 mm in height, 24–28 mm in width and 20 mm in depth, creating a space of 5–7 ml (Amine and Anand, 2015). A small/hypoplasic frontal sinus is an underdeveloped sinus cavity, size of a smaller peace, located above the frontal maxillar processus.…”

Trauma of the Frontal Region Is Influenced by the Volume of Frontal Sinuses. A Finite Element Study

Anatomy of frontal sinuses varies individually, from differences in volume and shape to a rare case when the sinuses are absent. However, there are scarce data related to influence of these variations on impact generated fracture pattern. Therefore, the aim of this study was to analyse the influence of frontal sinus volume on the stress distribution and fracture pattern in the frontal region. The study included four representative Finite Element models of the skull. Reference model was built on the basis of computed tomography scans of a human head with normally developed frontal sinuses. By modifying the reference model, three additional models were generated: a model without sinuses, with hypoplasic, and with hyperplasic sinuses. A 7.7 kN force was applied perpendicularly to the forehead of each model, in order to simulate a frontal impact. The results demonstrated that the distribution of impact stress in frontal region depends on the frontal sinus volume. The anterior sinus wall showed the highest fragility in case with hyperplasic sinuses, whereas posterior wall/inner plate showed more fragility in cases with hypoplasic and undeveloped sinuses. Well-developed frontal sinuses might, through absorption of the impact energy by anterior wall, protect the posterior wall and intracranial contents.

“…The floor comprises the medial portion of the orbital roof and can be confused with supraorbital ethmoid cells when these are highly pneumatized. The height of the frontal sinus averages 28–30 mm, with a width and depth of 20 mm, forming a space of 5–7 mL 14. The superior sagittal sinus typically travels along posterior to the intersinus septum and anterior to the crista gali, which are continuous with the perpendicular plate of the ethmoid inferiorly.…”

Craniomaxillofacial Trauma & Reconstruction

View full text Add to dashboard Cite

Frontal sinus fractures are an uncommon injury of the maxillofacial skeleton, and account for 5–15% of all maxillofacial fractures. As the force of impact increases, fractures may extend beyond the anterior table to involve adjacent skull, posterior table and frontal sinus outflow tract (FSOT). Fractures at these subsites should be evaluated independently to assess the need for and type of operative intervention. Historically, these fractures were managed aggressively with open techniques resulting in obliteration or cranialization. With significant injuries, these approaches are still indispensable. However, the treatment of frontal sinus fractures has changed dramatically over the past half-century, and recent case series have demonstrated favorable outcomes with conservative management. Concurrently, there has been an increasing role of minimally invasive endoscopic techniques, both for primary and expectant management, with a focus on sinus preservation. Here, we review the diagnosis and management of frontal sinus fractures, with an emphasis on subsite evaluation. Following a detailed assessment, an appropriate treatment strategy is selected from a variety of open and minimally invasive approaches available in the surgeon's armamentarium.
