title: [Mechanisms of onset and signs of latent mastoiditis in patients with exudative otitis media].
abstract: Tympanomastoidotomy was performed in 42 patients with exudative otitis media running from 4 to 8 weeks. Large size of the antral cells and high pneumatization of the translabyrinthine tract cells contribute to the onset of latent antritis; large size of the apical cells and hyperpneumatization of the cells of the inferior labyrinthine tract predispose to emergence of isolated apical mastoiditis in patients with exudative otitis media at early stages. Latent mastoiditis and mucoperiostitis in the region of perifacial and perilabyrinthine cells in patients with exudative otitis media are evidenced by early atypical cochleovestibular complaints, mixed hypoacusis and variability of tympanograms.
