The frontal sinus and the adjacent naso-orbitoethmoid complex of bones in the midline are vulnerable to direct trauma and significant injuries can involve the adjacent skull base, the nasofrontal duct, and the medial orbit. The anatomy of this critical area is complex. Assessment of the injury includes ocular and neurological examination for associated injuries, and high-resolution computed tomography scanning is required for accurate definition of the injury. In this chapter, the principles of management and the complications of these fractures and their management are described.

Necrosis Factor

Antitumor necrosis factor therapies have revolutionized the treatment of some inflammatory diseases. However, the use of these agents is associated with the development of many paradoxical autoimmune diseases. Less well-recognized is the association with sarcoidosis. We report a 55-year-old female with long-standing ankylosing spondylitis who developed persistent dry cough and dyspnea while receiving etanercept therapy. High-resolution computed tomography scanning showed mediastinal lymphadenopathy and multiple nodules in both lung fields developed two months after the administration of etanercept. Lymph node biopsy was not practicable. Histopathological examination of minor salivary gland biopsy revealed noncaseating granulomata, and the serum angiotensin-converting enzyme was very elevated. All infectious studies were negative. Etanercept was discontinued plus a course of corticosteroids with a clinical improvement, and a follow-up high-resolution computed tomography scanning 4 months later showed evident regression of mediastinal lymph nodes and pulmonary nodules. Potential pathogenic mechanisms of this paradoxical effect of tumor necrosis factor-alpha blocking agents are discussed.
