ABSTRACT
The article presents the clinical observation of 12 patients with chronic suppurative otitis media complicated with petrous pyramid cholesteatoma. According to the MoffatSmith 2008 classification, the following types of petrous pyramid cholesteatoma propagation have been revealed: supralabyrinthine (n = 1), supralabyrinthine – apical (n = 2), infralabyrinthine (n = 4), infralabyrinthine – apical (n = 3), massive (n = 1) and massiveapical (n = 1). We analyzed the clinical aspects of each post-surgery patient and surgical approaches of petrous pyramid cholesteatoma excision and the final result of surgical treatment. It has been noted that in infralabyrinthine petrous pyramid cholesteatoma no facial nerve damage which manifests itself in the form of mimic muscles paresis (paralysis) is observed unlike the supralabyrinthine type of cholesteatoma. The incidence of petrous pyramid cholesteatoma is 0.2%.
