Ostoclerose
Palabras clave:

A otospongiose é uma displasia óssea encontrada apenas no osso temporal humano e consiste em áreas de reabsorção únicas ou múltiplas seguidas de cicatrização com neoformação óssea. O resultado clínico da doença é a surdez condutiva quando da fixação do estribo na janela oval ou a surdez neurossensorial quando atinge o endósteo da cóclea. Atualmente a conduta clínica da otospongiose se restringe ao uso do fluoreto de sódio (20mg) associado ao lactato de cálcio, que podem amenizar a doença. Temos, neste momento, as seguintes propostas de tratamento clínico: inibidores de citocina, calcitonina de salmão e bisfosfonatos. Nesta breve revisão é evidenciada a etiopatogenia da otospongiose e a expectativa de novas condutas terapêuticas.
