Fractures of the anterior table of the frontal sinus vary from minimally displaced to severely displaced/comminuted depending upon the severity of the trauma and size of the sinus. Less severe trauma may result in fractures of the anterior table which are minimally (as illustrated) or nondisplaced.
Frontal sinus fractures are relatively uncommon and account for only 5-15% of maxillofacial fractures with a preponderance of male patients. The most common frontal sinus fractures involve a combination of the anterior and posterior tables with or without frontal recess involvement (about 2/3).
Each frontal sinus drainage pathway is located in the posterior, inferior, and medial portion of the sinus. The anterior wall of the frontal sinus is thick and resistant to injury. It requires greater force to fracture than any other facial bone (3.6 – 7.1 kN, Nahum AM (1975) The biomechanics of maxillofacial trauma.

Orbital floor fracture This is when a blow or trauma to the orbital rim pushes the bones back, causing the bones of the eye socket floor buckle to downward. This fracture can also affect the muscles and nerves around the eye, keeping it from moving properly and feeling normal.

Use secondary code (s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code. Type 1 Excludes.
The majority of frontal sinus fractures are the result of high velocity impacts such as motor vehicle accidents, assaults and sports injuries. Patients who sustain frontal sinus fractures often have associated facial fractures and systemic injuries.
A focused exam of the frontal sinus should include evaluation for any contour deformity and/or frontal lacerations and neurosensory deficits. Conscious patients should be questioned for the presence of clear nasal drainage or salty posterior nasal drainage that might be indicative of a CSF leak.#N#Examination of deep wounds should be performed under sterile technique, as these can be through and through injuries. The prognosis for such severe injuries is significantly worse and more aggressive management is indicated.#N#A high resolution CT scan with axial, coronal, sagittal and 3-D reconstruction is the gold standard for diagnosis.
A frontal recess injury involves the floor of the frontal sinus and the outflow tract. It may also involve the anterior skull base. Fractures of the anterior table of the frontal sinus vary from minimally displaced to severely displaced/comminuted depending upon the severity of the trauma and size of the sinus.
A suction is used to free the sinus of any blood or mucus. The posterior table and frontal recess can then be assessed with a 0° and/or 30° endoscope for evidence of mucosal lacerations, hematomas, or CSF leaks. Courses and events.

The frontal sinus is irregularly shaped and scalloped at its margins. Asymmetry of the sinus is the rule rather the exception (10% of individuals have a unilateral sinus, 9% of individuals have a rudimentary or absent sinus). Dimension of tables.
The anterior wall of the frontal sinus is thick and resistant to injury. It requires greater force to fracture than any other facial bone (3.6 – 7.1 kN, Nahum AM (1975) The biomechanics of maxillofacial trauma. ClinPlastSurg; 2:63).
The most severe anterior table injuries result in comminution of the anterior table bone. Posterior table fracture. Posterior table fractures carry a higher risk of intracranial injury because they create a communication with the intracranial space.
The sinus cavity is then suctioned free of any blood or mucous. An elevator and/or forceps are used to remove any bone or mucosa that has been displaced into the sinus cavity. Meticulous dissection technique should be used to avoid iatrogenic injury of the dura.
Transillumination. Alternatively, a light source (such as an endoscope) can be inserted through the anterior table bone defect. The light will transilluminate the sinus and delineate its margins. Beware of pitfalls such as soft-tissue and blood present in the sinus.
Mucosa removal. A clamp is used to stabilize the free anterior bone segment (s) that were previously removed. A large diamond burr is then used to remove the mucosa from the inner surface. The mucosa should also be stripped of any posterior table bone fragments to be used for reconstruction of the anterior wall. 8.
Postoperative imaging has to be performed within the first days after surgery. 3-D imaging (CT, cone beam) is recommended to assess complex fracture reductions. In centers where intraoperative imaging is available postoperative imaging can be performed at a delayed time.
Patients should be counseled that frontal sinusitis, mucocele formation, or any other signs of intracranial infection can occur years after the injury. The symptoms should be discussed with the patient including
The margins of the frontal sinus are irregular and may not be visible through the fracture. It is however critical to determine the precise margins of the sinus to allow for an accurate osteotomy and complete exposure of the sinus. There are several ways to accomplish this: Bayonet forceps. Transillumination.
