ABSTRACT

Os tumores glômicos, também chamados de paragangliomas, são formados por células não cromafins. O tumor é tipicamente vascular formado por vasos capilares e pré-capilares, interposto por células epiteliais. Para a sua abordagem inicial, deve-se ressaltar que os sintomas mais comumentes encontrados são o zumbido pulsátil e hipoacusia. A investigacão através de imagem (tomografia computadorizada e ressonância magnética) se faz necessária. Apresentaremos neste trabalho 5 pacientes portadores de paragangliomas timpânicos atendidos no Hospital (de 1995 a 2001). O sexo predominante foi o feminino, a idade variou de 48 a 60 anos, com média de 50 anos. A queixa predominante foi o zumbido pulsátil e a hipoacusia. A conduta foi cirúrgica em todos os casos.

ABSTRACT

Glomus tumors, also called paragangliomas, originate from nonchromaffin cells. The tumor is typically vascular and grows from capillary and pre-capillary vessels in-between epithelial cells. It is worth mentioning that the most common symptoms are pulsating tinnitus and hearing loss. Imaging studies (CT and MRI) are necessary for diagnosis. This paper shows five patients seen at the Hospital between 1995 and 2001 presenting glomus tympanicum. Women were most commonly affected, and the age ranged from 48 to 60 years (mean age of 50 years). The most common complaints were pulsating tinnitus and hearing loss. All patients were treated surgically.
