Diving-related inner ear injuries.

Diving-related inner ear barotrauma (IEB) and inner ear decompression sickness (IEDS) most often result in permanent severe cochleovestibular deficits, unless immediate diagnosis is reached and the correct treatment is commenced early. Nine cases of sport-diving-induced inner ear injuries that were referred to the Israeli Naval Hyperbaric Institute between October 1987 and September 1989 are presented with regard to evaluation, treatment, and follow-up. The diagnosis was IEB in five divers and IEDS in four. Explorative tympanotomy was carried out with remarkable results in two patients with IEB, while the remaining three were relieved by bed rest alone. Three of the four IEDS patients were recompressed according to the extended US Navy Table 6 with good short-term results. The role of complete otoneurological evaluation in the decision-making process leading to the correct diagnosis and treatment is emphasized.

Hyperbaric oxygenation for necrotizing (malignant) otitis externa.

Two patients with extensive necrotizing otitis externa have been treated by hyperbaric oxygenation. One patient had facial nerve palsy and the other suffered from skull base involvement. Due to severe side effects, the preferred combined intravenous antibiotic therapy was changed to monotherapy in one case and completely withdrawn in the second. This was done before the commencement of hyperbaric oxygenation, while the necrotizing infection was still active. Hyperbaric oxygenation therapy was followed by complete resolution of the necrotizing otitis externa, which did not recur. The pathogenesis of the disease and mechanisms by which hyperbaric oxygenation might be of benefit are described. We conclude that hyperbaric oxygenation should be considered as adjuvant therapy for necrotizing otitis externa whenever a therapeutic pressure chamber is available.

Tonsillar leiomyoma.

Tumors of smooth muscle origin are rare in the oral cavity. To date, only eighty-three cases of oral leiomyomas have been reported. A first case of tonsillar leiomyoma in a 73-year-old male is presented. The theories of origin and the various histologic types of oral leiomyomas are discussed. Leiomyoma can easily be confused with other spindle-cell tumours. Special stains are necessary to reach a correct diagnosis. It is sometimes difficult to differentiate benign leiomyoma from malignant leiomyosarcoma. The use of mitotic figure count to indicate malignant behaviour is not always reliable. The need for wide surgical excision of the tumour, complete sectioning and examination of the specimen and meticulous follow-up of the patient for evidence of recurrence are emphasized.
