Histopathological changes to the peripheral vestibular system following meningitic labyrinthitis

Abstract: Objective: While cochlear ossification is a common sequela of meningitic labyrinthitis, less is known about the effects of meningitis on the peripheral vestibular end organs. Herein, we investigate histopathologic changes in the peripheral vestibular system and cochlea in patients with a history of meningitic labyrinthitis. Methods: Temporal bone (TB) specimens from patients with a history of meningitis were evaluated and compared to age-matched controls. Specimens were evaluated by light microscopy and assess… Show more

“…Our report uniquely examines a surgical specimen from within the labyrinth obtained 16 months after the acute injury, which allows us to correlate histopathologic findings to the patient's clinical progression. In postmortem human samples, the histopathology of LO is typically characterized as extensive ossification of the labyrinth with nearby fibrous tissue and inflammatory cells (1,4). In our sample, we note woven (i.e., immature) bone surrounded by collagen within the canalicular space, but a marked lack of inflammation.…”

“…Estudos com ossos temporais humanos têm fundamentado a fisiopatologia de diversas doenças que afetam a orelha, contribuindo para o conhecimento clínico específico (Monsanto et al, 2018;Pauna et al, 2020a). Não somente o detalhe histológico bidimensional é importante para melhor compreensão do labirinto, mas sua configuração tridimensional também é significativa para entendimento de sua fisiologia (Uzun;Curthoys;Jones, 2007).…”

“…As escalas timpânica e vestibular foram afetadas em 100% e 50% dos ossos temporais, respectivamente (Merchant;Gopen, 1996). Estudo recente com ossos temporais de pacientes com histórico de meningite encontrou redução significativa do número de células do gânglio espiral (redução média de 45%, variando entre 25,3% e 80,9%), em comparação a ossos temporais pareados pela idade (controle) (Pauna et al, 2020a).…”
