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)
To compare the results of hearing preservation surgeries using different approaches--the enlarged middle cranial fossa approach and the retrosigmoid approach--and different classification systems, stressing the importance of preserving "normal hearing," we performed a retrospective case review in a tertiary care medical center. The charts of 107 patients(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)
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 To determine whether early and late postoperative facial nerve function can be predicted on the basis of electromyographic responses in acoustic neuroma surgery. SETTING Prospective blinded study. DESIGN Tertiary referral center. PATIENTS AND METHODS Burst and train electromyographic responses were recorded intraoperatively during the last(More)
OBJECTIVE This study aimed to determine whether postoperative facial nerve paralysis or surgical manipulation causing paralysis could be predicted on train responses during intraoperative facial nerve monitoring in acoustic neuroma surgery. STUDY DESIGN AND SETTING This was a prospective study performed at a tertiary referral center. PATIENTS AND(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)
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 describe and analyze the main outcomes achieved in a series of patients with sporadic vestibular schwannoma (VS) larger than 40 mm in extrameatal diameter, defined as giant VS, submitted to microsurgery by the enlarged translabyrinthine approach with transapical extension. STUDY DESIGN Retrospective chart review. SETTING Tertiary referral(More)
A case of a Jehovah's witness affected by an intracanalicular vestibular schwannoma with an extremely fast growth rate is presented. Nine months after presentation, the tumor reached 23 mm in the cerebellopontine angle. A partial removal through a retrosigmoid approach was planned. Because of the presence of a dominant high jugular bulb masquering the(More)
