A short time delay before starting treatment (within 10 days), treatment with high doses of steroids and hyperbaric oxygen, preserving complete caloric function of the labyrinths, normal function of the thyroid, and seasonal occurrence of the disease in the spring were positive prognostic factors for hearing recovery in SSNHL.

Malignant external otitis (MEO) is an invasive, morbidity, even mortality, mainly pseudomonal infection of the external auditory canal, frequently involving the base of the skull, multiple cranial nerve and the meninges. In many cases conventional therapy has been prolonged, intensive and relatively ineffective, especially in infections other than bacterial (mainly fungal). We presented theoretical principles of hyperbaric oxygen (HBO) treatment in MEO, our own experience and others' experience in applying this treatment method. We treated eight patients with MEO applying pharmacotherapy, topical management, surgery in one case and also adjunct HBO. In six patients, infection was caused by Pseudomonas aeruginosa, in one by Staphylococcus sp. and in one by Aspergillus sp. Complete recovery was achieved in seven patients. In the patient with MEO caused by Aspergillus sp., intracranial complications developed and the patient died. Our experiences in employing HBO in bacterial-caused MEO have confirmed the role of HBO as a valuable, beneficial, supporting classical treatment method. Small number of patients with MEO, especially with non-bacterial infection, and unforeseen clinical course of disease make our experience difficult to objectivize.

We conclude that hyperbaric oxygen therapy with high doses of glucocorticoids improves the results of conventional sudden sensorineural hearing loss treatment and should be recommended. In addition, the best results are achieved if the treatment is started as early as possible.

A retrospective review of children diagnosed and treated for suppurative complications of paranasal sinusitis was undertaken to describe clinical presentation, microbiology, and treatment. This review includes children with subgaleal abscess and osteomyelitis of the frontal bone, subdural empyema, frontal lobe abscess, meningitis, and encephalitis. Staphylococcus aureus and group C beta-hemolytic Streptococcus were isolated agents. All children were treated with intravenous antibiotics with drainage of both the sinus and extracranial and intracranial suppurations. Results of treatment in the series support the opinion that combined aggressive surgical and antibiotic treatment is a preferred method in complicated sinusitis in children.
