The frontal sinus is located centrally at the anterior skull base. The frontal recess constitutes the only outflow tract for the sinus. Fractures of the floor of the sinus will often disrupt sinus outflow and must be addressed.
Regardless of anterior or posterior table injuries, fractures that obstruct sinus drainage will require either:
- Endoscopic frontal sinosotomy when indicated
- Sinus obliteration.
|Any frontal sinus fracture resulting in nasofrontal recess injury.|
|Observation (and when indicated frontal sinus endoscopy)|
|Anterior table fractures involving the sinus floor with questionable nasofrontal recess injury.|
Careful follow up and patient compliance is essential. The patient should be educated as to what symptoms to look for and a follow up scan should be obtained within 6 weeks to 3 months.
