Management of frontal sinus fractures with posterior table involvement: a retrospective study

Management of frontal sinus fracture has been a matter of debate. Combined fractures of the anterior and posterior walls have been managed by various techniques, including observation, open reduction and internal fixation, ablation, obliteration, and, most recently, cranialization. The earlier techniques have met with frequent complications, including sinusitis, mucopyocele, cerebrospinal fluid leak, meningitis, and brain abscess, along with various chronic pain symptoms. Cranialization of the frontal sinus was first introduced for injuries of both walls with intracranial penetration. From 1990 to 1996, frontal sinus fractures of 11 patients (10 men and 1 woman) were treated using the cranialization procedure. Based on patient history, clinical findings, radiographic diagnoses, operative techniques, and follow-ups of these patients the authors conclude that cranialization of the frontal sinus is a safe and effective method of treating posterior table frontal sinus fractures.
