Unilateral injuries can be treated by removing the intersinus septum or reconstructing the duct with mucosal flaps or stents. Most authors do not recommend the use of mucosal flaps or stents because of the high failure rate and removal of the intersinus septum is controversial as well and not uniformly advocated. Obliteration, however is a safe and reliable method of treatment. All bilateral injuries should be obliterated. These injuries involve a tear in the forehead skin, fracture to both the anterior and posterior walls, laceration of the dura and often contusion of the adjacent frontal lobes.
Ablation is used only if absolutely necessary with cranialization being the treatment of choice.
Reconstruction of the anterior wall is attempted using fragments of the anterior and posterior wall that have been scrubbed with betadine solution. Early complications of frontal sinus surgery consists of frontal sinusitis which is initially treated medically with decongestants and antibiotics, however if painful swelling of the forehead or eye develops prompt surgical intervention and obliteration is indicated. Meningitis, deformity, pain and hypesthesia are other early complications that may be observed. Late complications of frontal sinus surgery consists of mucocele, mucopyocele and brain abscess and are treated with either obliteration or cranialization. He had no loss of consciousness and his only symptoms were pain over the forehead and a small amount of epistaxis.
