Abstract
Frontal sinus fractures typically reflect high-energy trauma and must be evaluated and treated carefully to avoid long-term problems including contour deformity, sinus dysfunction, cerebrospinal fluid (CSF) leakage, chronic sinusitis, and mucocele formation. This article outlines frontal sinus anatomy, diagnostic pathways, and evolving treatment concepts in detail. An anatomically driven treatment algorithm is emphasized, with a focus on preservation of sinus function whenever possible and preference for conservative management. Advanced procedures, such as endoscopic sinus surgery and cranialization, are reviewed in the context of managing more severe injuries. Key points: (1) Clinical decision-making in the management of frontal sinus fractures is best guided by evaluating the status of the anterior table, posterior table, and nasofrontal outflow tract, with treatment options ranging from nonoperative care to open or endoscopic surgery. (2) Improvements in endoscopic techniques, combined with evidence supporting less aggressive strategies, have shifted management toward more conservative approaches, reserving open procedures for higher-grade injuries. (3) Extended follow-up is essential to identify delayed problems such as mucoceles, chronic sinusitis, frontal bone osteomyelitis, and contour irregularities.
