ABSTRACT

A fístula oroantral é a comunicação patológica entre cavidade oral e seio maxilar, quase sempre decorrentes de traumatismos durante procedimentos dentários. OBJETIVO: Apresentar experiência de 25 casos. CASUÍSTICA E MÉTODOS: Realizado estudo retrospectivo de pacientes com FOA no período de 1996 a 2000. O diagnóstico incluiu exame otorrinolaringológico, endoscopia nasal ou da fístula, tomografia computadorizada das cavidades paranasais, pesquisa bacteriológica, fúngica e análise patológica. RESULTADOS: Encontrados 25 casos, sendo 10 de segundo molar, 8 de primeiro molar, 6 de segundo pré-molar e 1 de canino. Todos foram operados pela técnica de Caldwell-Luc, reavivamento das bordas da fístula, meatotomia média e rotação de retalho mucoso geniano. DISCUSSÃO: Nas fístulas de alto débito (n=14), colocou-se enxerto ósseo da própria parede anterior do seio. Todos, exceto um, tiveram resultado cirúrgico bom. A cultura bacteriológica (n=19) demonstrou estreptococos pneumoniae (13), haemophilus influenzae (6), moraxella catarrhalis (2), estafilococos aureus (2). Encontrado aspergilus niger em um caso que apresentava imagem radiológica de bola fúngica. CONCLUSÕES: Após 30 dias, os resultados foram bons em todos, exceto um dos casos. Este foi reoperado com colocação de enxerto ósseo, inicialmente não utilizado, tendo sucesso. Após 6 meses, todos os 23 pacientes localizados não apresentavam problemas.


The oroantral fistula is a pathological connection between the maxillary sinus and with the oral cavity. The condition mostly follows dental extraction. AIM: To present the experience of 25 cases. MATERIAL AND METHODS: Retrospective cases between 1996-2000. The ORL examination included nasal or sinusal endoscopy, a CT scan and histopathological analysis. RESULTS: Twenty-five cases were found: ten 2nd molar cases, eight 1st molar cases, six 2nd premolar cases, and one canine case. All patients underwent a Caldwell-Luc operation plus excision of the epithelium lining the fistula, that was then completely covered by a flap of mucosa rotated from the genian region. DISCUSSION: In cases of major fistulae a bone autograft taken from the anterior sinus wall was used. Bacterial cultures (n=19) revealed streptococus pneumoniae (13), haemophillus influenza (6), Moraxella catharralis (2) and staphylococus aureus (2). Aspergillus niger was found in one case presenting as a "fungic ball". CONCLUSIONS: The only case of surgical failure, after 30 days postoperatively, was reoperated, using a bone graft. After a 6-month follow up all of the patients progressed satisfactorily, including the reoperated patient.

ABSTRACT

Mucormycosis is an opportunistic fungal infection that is caused by normally saprobic organism of the class Zygomycetes. The main form of mucormycosis are pulmonary and rhinocerebral. Rhinocerebral mycormycosis typically starts in the maxillary antrum, particularly in poorly controlled diabetics. Invasion of surrounding tissue can cause necrotizing ulceration of palate with a blackish slough and exposure of bone. A case of mucormycosis presenting as palatal performation is discussed in this article.
