Abstract Introduction: It is difficult to evaluate the effect of drugs clinically used for idiopathic sudden sensorineural hearing loss, mainly because its underlying mechanism remains unknown. Objective: This study assessed the efficacy of hyperbaric oxygen therapy or ozone therapy in the treatment of idiopathic sudden sensorineural hearing loss, when either therapy was included with steroid treatment. Methods: A retrospective analysis examined 106 patients with idiopathic sudden sensorineural hearing loss seen between January 2010 and June 2012. Those with an identified etiology were excluded. The patients were divided into three treatment groups: oral steroid only (n = 65), oral steroid + hyperbaric oxygen (n = 26), and oral steroid + ozone (n = 17). Treatment success was assessed using Siegel criteria and mean gains using pre- and post-treatment audiograms. Results: The highest response rate to treatment was observed in the oral steroid + ozone therapy group (82.4%), followed by the oral steroid + hyperbaric oxygen (61.5%), and oral steroid groups (50.8%). There were no significant differences in the response to treatment between the oral steroid and oral steroid + hyperbaric oxygen groups (p < 0.355). The oral steroid + ozone group showed a significantly higher response rate to treatment than the oral steroid group (p = 0.019). There were no significant differences between the oral steroid + hyperbaric oxygen and oral steroid + ozone groups (p = 0.146). Conclusion: The efficiency of steroid treatment in patients with severe hearing loss was low. It was statistically ascertained that adding hyperbaric oxygen or ozone therapy to the treatment contributed significantly to treatment success.
Resumo Introdução: É difícil avaliar o efeito dos fármacos clinicamente usados na surdez súbita idiopática, principalmente porque o seu mecanismo subjacente se mantém desconhecido. Objetivo: Avaliar a eficácia da oxigenoterapia hiperbárica ou ozonioterapia no tratamento de surdez súbita, quando uma ou outra terapia é incluída no tratamento com esteroides. Método: Uma análise retrospectiva examinou 106 pacientes com surdez súbita atendidos entre janeiro de 2010 e junho de 2012. Aqueles com uma etiologia identificada foram excluídos. Os pacientes foram divididos em três grupos de tratamento: apenas esteroide oral (n = 65), esteroide por via oral + oxigenoterapia hiperbárica (n = 26) e esteroides por via oral + ozônio (n = 17). O sucesso do tratamento foi avaliado com critérios de Siegel e os ganhos médios com audiogramas pré e pós-tratamento. Resultados: A taxa de resposta mais elevada para o tratamento foi observada no grupo de esteroide + ozonioterapia (82,4%), seguida por grupos de esteroide oral + oxigenoterapia hiperbárica (61,5%) e esteroide oral (50,8%). Não houve diferenças significantes na resposta ao tratamento entre os grupos de esteroide oral e esteroides + oxigenoterapia hiperbárica (p < 0,355). O grupo de esteroide oral + ozônio apresentou uma taxa de resposta significantemente mais elevada ao tratamento do que o grupo de esteroide oral (p = 0,019). Não houve diferenças significantes entre os grupos de esteroide oral + oxigenoterapia hiperbárica e esteroide oral + ozônio (p = 0,146). Conclusão: A eficiência do tratamento com esteroides em pacientes com perda auditiva grave foi baixa. Verificou-se estatisticamente que a adição de oxigenoterapia hiperbárica ou ozonioterapia ao tratamento contribuiu significantemente para o sucesso do tratamento.

Salivary gland neoplasms are rare in childhood. Only 1 to5.5% of minor salivary gland tumours occur in children and adolescents. The most common malignant minor salivary gland tumours are mucoepidermoid carcinomas (MECs). Herein, we present a rare case of mucoepidermoid carcinoma occuring in the hard palate. Presentation of Case: A 12-year-old boy visited our hospital with a swelling and ulceration of the right hard palate. Clinical examination revealed a localized mucosal nodule of the right posterior hard palate, measuring 1*1 cm. Biopsy was performed. The tumour was diagnosed as a low grade MEC. Wide excision was performed. The patient didn’t need another therapy. During 15-month follow-up, the patient showed no evidence of local tumour recurrence or metastasis. Discussion: Mucoepidermoid carcinoma occurring in the oral cavity is extremly rare. These tumours are usually presenting as a painless, reddish-purple nodüle. Biopsy is necessery for definitive diagnosis. Histologically, MECs are divided into low, intermediate and high grade subtypes. Differantial diagnosis of palatal tumours in children include pleomorphic adenoma, benign or malignant mesenchymal tumours, and less commonly giant cell granuloma. A wide local excision with safe free margins is the operative procedure for low-grade MECs.
