OBJECTIVES/HYPOTHESIS A relation between conventional radiotherapy and the development of intracranial neoplasma is well known, but radiation-associated tumor following stereotactic radiotherapy of vestibular schwannoma is underestimated. In this article we will study this relation by doing a complete literature review on all the malignant intracranial(More)
OBJECTIVE The objective of this study was to examine the usefulness of intraoperative cochlear nerve monitoring (ICNM) in the preservation of normal and social hearing in vestibular schwannoma (VS) removal. METHODS A retrospective chart review was conducted. Of 1315 patients operated for VS between June 1988 and December 2005, 150 patients were subjected(More)
OBJECTIVES To discuss our management strategy of vestibular schwannoma in patients with neurofibromatosis type 2 (NF2). STUDY DESIGN Retrospective study. SETTING Quaternary referral skull base center. METHODS Thirty-eight NF2 patients who had undergone 48 operations at the Gruppo Otologico between January 1988 and December 2008. The mean age at time(More)
OBJECTIVE To describe our experience in the management of patients with squamous cell carcinoma of the temporal bone (TBSCC) and to identify factors predictive of outcome. STUDY DESIGN Retrospective study. SETTING Quaternary referral otology and skull base center. PATIENTS A total of 45 consecutive patients with histologically confirmed TBSCC were(More)
OBJECTIVE To evaluate the results of the surgical removal of residual vestibular schwannomas and compare them with results obtained from the first operation. STUDY DESIGN Retrospective case review. SETTING Tertiary otologic and skull base referral center. PATIENTS Twenty-three patients with residual vestibular schwannoma from a total of 637 patients who(More)
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(More)
BACKGROUND Vestibular schwannomas (VSs) are the most common cerebellopontine angle tumors, accounting for 75% of all lesions in this location. OBJECTIVE To evaluate the results after removal of VS through the enlarged translabyrinthine approach, which is a widening of the classic translabyrinthine approach that gives larger access and provides more room(More)
OBJECTIVE Review of postoperative morbidity and facial nerve outcomes of cystic vestibular schwannoma (CVS) patients compared with solid vestibular schwannoma (SVS) patients and a proposal for a new CVS classification system. STUDY DESIGN Retrospective review. SETTING Tertiary care facility. PATIENTS Ninety-six patients with surgically treated CVS(More)
OBJECTIVE To study the clinical features, tumor characteristics and outcomes of giant cell tumors (GCTs) in the skull base based on long-term follow-up. We also report the largest series of GCTs in the temporal bone and the lateral skull base. MATERIALS AND METHODS A retrospective study was conducted of all GCTs managed at the Gruppo Otologico, a(More)
OBJECTIVE To compare hearing preservation and facial nerve function outcomes in patients undergoing vestibular schwannoma surgery performed using either the middle cranial fossa approach (MCFA) or the retrosigmoid approach (RSA). MATERIALS AND METHODS A review of the medical records of patients diagnosed with vestibular schwannoma who underwent surgical(More)
