“…In our experience, with this approach hearing could not be preserved with a fistula in the basal turn of the cochlea [Omran et al, 2006]. Hawthorne and Fisch [1989] in their series had a similar experience in such cases.…”

“…Bartels [1991] presented a review of 80 cases that were mentioned in the literature till 1991; we tried to compare the review of this case series and the one done by him. Part of this series has already been published by the senior author [Omran et al, 2006;Sanna et al, 1993]; we included those cases in our series.…”

Objective: To discuss the classification of petrous bone cholesteatoma (PBC) and add a subclassification; to review the existing literature and to propose the ideal surgical management of PBC based upon the experience of the largest series published in the literature until now. Study Design: Retrospective analysis. Setting: Quaternary referral neuro-otologic private practice. Materials and Methods: The data of 129 patients who underwent surgery for PBC between 1979 and 2008 were analyzed with respect to the classification, type of the approach used, facial nerve lesion and its management, recurrences and outcome. Results: Out of the 129 PBC cases 64 were supralabyrinthine, 9 infralabyrinthine, 7 infralabyrinthine-apical, 48 massive and 1 apical. The facial nerve was involved in 95% of the cases. Hearing could not be preserved in 82% of the cases due to the extent of the lesions and the surgical approaches used. The internal carotid artery, jugular bulb and the lower cranial nerves were infrequently involved, but demanded careful identification and meticulous care to avoid complications. Obliteration of the cavities provided a safe solution for protection of the exposed dura and the vital neurovascular structures. Recurrences were observed in 5 cases. Conclusion: The classification of PBC is fundamental to choose the appropriate surgical approach; the facial nerve is involved in almost all the cases, radical removal takes priority over hearing preservation and cavity obliteration is important to protect the vital neurovascular structures which may be exposed.

The objective of this study was to expose our results in the treatment of petrous bone cholesteatomas (PBC), paying attention to diagnosis, surgical strategy, facial management, results, and recurrences. The main objective is to compare the results of obliterative and open techniques in their management concerning the recurrence rate, due to the controversy elicited on obliterative or closed techniques in large cholesteatomas. A retrospective study was performed from July 1977 to September 2007 at the Tertiary referral cranial base center. Thirty-five patients were treated for PBC through different surgical approaches, and in 25 cases (72%) the surgical cavity was obliterated with a muscle flap. Four patients (11%) had a long-term recurrence. These patients received an open technique and after surgical re-exploration using a closed technique they had no recurrence. There were no recurrences in patients who underwent an obliterative technique and they received periodic MRI controls. The facial function after surgery was acceptable (71% of patients had House-Brackmann grades I to III). PBC is a complex pathology and presents difficulties in its diagnosis and treatment. Surgical technique should be suitable for removing the pathology and preventing damage to structures such as the facial nerve or great vessels. Obliterative techniques, where possible, are at least as safe as open cavity procedures and they have fewer postoperative complications; however, regular follow-up with CT and MRI is mandatory.
