OBJECTIVE The objective of this study was to compare the effectiveness of direct eighth nerve monitoring (DENM) and auditory brainstem response (ABR) in facilitating hearing preservation during vestibular schwannoma resection. STUDY DESIGN This was a retrospective study. SETTING : Tertiary referral center. METHODS We conducted a retrospective clinical(More)
OBJECTIVE To compare the natural history of acoustic neuroma growth to the reported growth rate of acoustic neuromas after radiosurgical therapy, a retrospective review and meta-analysis of the literature was performed. The retrospective review was of one hundred eleven patients (average age, 71 yr) who chose to have their acoustic neuromas managed(More)
BACKGROUND Idiopathic Sudden Sensorineural Hearing Loss (ISSNHL), commonly defined as greater than 20 dB of unilateral hearing loss in at least 3 frequencies occurring within 3 days, has a reported incidence of 5 to 20 per 100,000 patients per year. Untreated, it has a recovery rate of 32 to 65%. Although accepted therapy is high-dose prednisone taper(More)
This article is a concise clinical review of preoperative, intraoperative, and postoperative auditory evaluation of patients with acoustic neuroma. The author describes behavioral audiometry, auditory brainstem response, and otoacoustic emissions for preoperative evaluation; auditory brainstem and direct eighth-nerve intraoperative monitoring for(More)
The advent of magnetic resonance imaging (MRI) has significantly increased the clinician's ability to detect small vestibular schwannomas. This had led to controversy in the evaluation of patients with asymmetric sensorineural hearing loss, as some recent studies have suggested that the auditory brainstem response (ABR) does not adequately detect small(More)
OBJECTIVES This article seeks to demonstrate the use of the extended middle cranial fossa approach in the treatment of tumors arising in the anterior cerebellopontine angle and petroclival region. STUDY DESIGN We conducted a retrospective chart review. SETTING Tertiary referral center. PATIENTS : Ten-year retrospective chart review of over 800 skull(More)
Anacusis following hearing preservation surgery for acoustic neuroma removal in which the cochlear nerve was preserved has been explained on the basis of neural or vascular compromise. In the absence of pathologic evidence for either theory, a physiologic model was chosen. Electrical promontory stimulation with monitoring of subjective and electrically(More)
BACKGROUND Pharmacologic agents targeted against the ErbB family, or the intracellular pathways that mediate their effects, could slow clinical progression of vestibular schwannoma (VS) in patients where other modalities carry a high risk-to-benefit ratio. OBJECTIVE Determine the identity of the predominant ErbB dimer partners in VS tumors and assess the(More)
OBJECTIVES/HYPOTHESIS To review the short- (<1 yr) and long-term (>1 yr) surgical and hearing outcomes for congenital aural atresia and to analyze the stability of surgical results over time. STUDY DESIGN Retrospective chart review of 45 patients (54 ears) who underwent surgery for congenital aural atresia during a 5-year period at a tertiary care(More)
OBJECTIVES This study aimed to evaluate the relationship between cochlear signal on fluid-attenuated inversion recovery (FLAIR) magnetic resonance imaging (MRI) sequences and hearing in patients undergoing hearing preservation surgery for vestibular schwannoma (VS) and to demonstrate a new classification system to be used in imaging evaluation of patients(More)
