“…Generally, fractures of the frontal bone are associated with high impact trauma and dynamic forces, such as traffic accidents, assaults, and sport accidents (May, 1970; Tiwari et al, 2005; Bell et al, 2007; Mithani et al, 2009). The injuries of the frontal region are varying, as they range from isolated fractures of the anterior sinus' wall, to very complex fractures involving the orbit and skull base (Strong et al, 2006; Holier et al, 2010; Dimitrijevic et al, 2014).…”

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.

“…In the last 15 years, in many of the frontal sinus fractures and their complications, such as CSF fistulas, injuries to the frontonasal duct, mucopyoceles and orbit complications, the nasal endoscopic techniques associated or not to the open techniques are being increasingly indicated by otorhinolaryngologists 10,15,19,23,25,26 . The latter, just as the open approach, allow the use of muscle fascia or nasal and oral mucosa free grafts, or evens the use of aloplastic material to correct dura mater defects [11][12][13]17,18,20 .…”

Even today, the use of more aggressive techniques such as packing, obliteration and cranialization of the frontal sinus generate controversies 10,17,20,18,25,27 . A number of papers show different approaches, varying from conservative measures, all the way up to aggressive surgery, especially in cases of intracranial and orbit complications [11][12][13]17,19,22,23 .…”

“…Notwithstanding, his procedure was an exception, because the patient had osteomyelitis and bone sequester in the frontal sinus after late referral (4 weeks) to our service. Techniques such as Rydell's procedure, frontal sinus ablation, are rarely performed, because they may cause gross facial deformation 7,11,12,20,25,26 . Therefore, we may state that the decision about the best time to treat and the technique employed will depend on lesion severity and extension, and a full clinical assessment of both the patient and the injury.…”

The frontal sinus trauma is not rare and it is 8% of the facial fractures. It can affect the anterior and/or posterior plates, with or without hitting the nasofrontal duct. It has a large potential of complications and its management still being a controversy. Objective: To present the casuistic of fractures frontal sinus, the epidemiology and clinical and surgical management of frontal sinus fractures. Materials and Methods: Not randomized retrospective study of 24 patients with frontal sinus fractures Hospital of Clinics, School of Medicine Botucatu, São Paulo, Brazil. Results: From the 24 patients, we had 16 (66,6%) fractures of the extern plate and 8 (33,4%) of both. In 2 patients the nasofrontal duct was involved. Others facial fractures were associated in 20 (83,4%) cases and major lesions of the cerebral segment were found in 13 (54,2%). Subpalpebral incision was performed in the majority with satisfactory aesthetic results. The basis of the surgical treatment was reduction and fixation with different materials (steel wire, mononylon, titanium miniplates) and if necessary we used alogen implants or parietal bone to reconstruct the anterior plate. Conclusion: The principal cause of frontal sinus fractures is crashed car. The management depends of the complexity, because commonly there are cranioencephalic lesions associated. The surgical thecniques used are the incisions, bicoronal flap or browglabella, infra-orbital rim ("butterfly"), associated a endoscopy sinus surgery in cases of infection, cerobrospinal fluid leak and orbital complications.

The osteoplastic frontal sinus surgery with obliteration of the sinus has been established in the therapy of frontal sinus diseases that can not be drainaged permanently or healed through an endonasal access. The obliteration of the frontal sinus is endangered in cases of multiple fracturing of the posterior frontal sinus wall or if it has been destroyed by an inflammatory process. In these problematic cases obliteration bears the danger of complications and cranialization of the frontal sinus is therefore the method of choice. We review 8 patients who were operated on using the cranialization technique. Indications for surgery were a combined fracture of the anterior and posterior frontal sinus wall (3), a pyocele of the frontal sinus with extensive destruction of the posterior wall (4) and a large osteoma of the posterior frontal sinus wall (1). The frontal sinus was exposed through a coronal incision, the mucosa and the posterior wall were completely removed and the frontal sinus obliterated with fat tissue. The anterior sinus wall was replaced after obliteration of the sinus or reconstructed with calvarian bone transplants. The follow up period was 1.8 years (11 months to 8 years). All patients underwent postoperatively a clinical ENT-examination and radiological assessment by CT-Scan or MRI. The overall functional and esthetic outcome was excellent. There were no serious complications nor any recurrence. The cranialization of the frontal sinus is a reliable and safe variation of the classical osteoplastic frontal sinus surgery with fat obliteration.
