Frontal sinus fractures constitute 5% to 15% of maxillofacial fractures, and isolated anterior table injuries account for 33% of frontal sinus fractures. The treatment strategy of frontal sinus fractures should be individualized according to the extent of the injury. Endoscope-assisted repair without any fixation method for the treatment of mildly and moderately displaced (1–5 mm) and closed isolated anterior table frontal sinus fractures is a good alternative technique for treatment.
Between April 2010 and December 2011, 5 patients with mildly and moderately displaced isolated anterior table fractures were treated. There were no lacerations in forehead skin of the patients. Preoperatively, the patients showed forehead depression at the fracture site, and computed tomography scan was taken to determine the extent of the frontal sinus fracture. Endoscope-assisted closed reduction treatment was applied to all patients.
All fractures were reduced successfully. None of the patients needed to undergo conversion to traditional incision techniques. No patients required fixation materials. Cosmetic deformity was corrected in all patients perfectly.
In the standard treatment modality of frontal sinus fractures, repair is best performed by a coronal approach. However, bicoronal incision has many disadvantages. Several authors have recently described some endoscopic and closed approaches to these injuries. The main disadvantages of these methods are poor visualization or fixation requirement with exogenous materials.
Endoscopic reduction of mildly and moderately displaced closed isolated anterior table frontal sinus fractures without fixation is feasible. It results in a good clinical outcome in selected cases.
