CT after high-energy trauma shows a comminuted displaced posterior-table frontal sinus fracture, dural breach and persistent CSF leak. The nasofrontal outflow tract is disrupted. What is the best definitive principle?
Severe posterior-table disruption with persistent CSF leak and outflow injury requires separation of the intracranial space from sinonasal mucosa, secure dural closure and management of the frontal recess.
A. Closed nasal reduction alone: This does not address the posterior table, dura or contaminated sinus.
B. Observe indefinitely because many leaks stop: The combination of comminution, displacement and outflow disruption carries persistent meningitis and mucocele risk.
C. Obliterate only the nasolacrimal duct: This is not the frontal sinus drainage pathway or dural defect.
D. Multidisciplinary cranialisation with dural repair and exclusion of the sinonasal tract: Severe posterior-table disruption with persistent CSF leak and outflow injury requires separation of the intracranial space from sinonasal mucosa, secure dural closure and management of the frontal recess.
E. Perform cosmetic forehead camouflage without sinus treatment: Contour correction alone leaves the intracranial communication untreated.
If the posterior-table fracture were minimally displaced, the outflow tract patent and the leak resolved promptly, close radiological and clinical observation could be appropriate.
