Invasive Pseudomonas osteitis of the temporal bone.

Advances in the diagnosis and treatment of invasive Pseudomonas osteitis have improved the prognosis of this condition. The addition of hyperbaric oxygen therapy to the newer antibiotic regimens appears to enhance their efficacy. Radionuclide scanning can result in earlier diagnoses and also determine an end point for therapy. Surgical intervention should be reserved for those patients who do not respond to medical therapy and should be governed by knowledge of the temporal bone histopathology from available specimens.
