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)
OBJECTIVES/HYPOTHESIS Auditory brainstem response (ABR) testing and magnetic resonance imaging (MRI) are compared for the evaluation of patients with asymmetric sensorineural hearing loss (SNHL). MRI with gadolinium administration is the current gold standard for identifying retrocochlear lesions causing asymmetric SNHL. The study seeks to determine the(More)
Leiomyoma is a benign myogenic tumor that may develop wherever smooth muscle is present. It occurs commonly in the uterus, skin, and gastrointestinal tract and is rare within the nasal cavity. Only three of twenty-four reported cases of sinonasal leiomyoma have been found to originate from the nasal septum. Treatment of choice for these neoplasms is(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)
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)
OBJECTIVE The purpose of the study was to identify specific aspects of surgical approach design and closure technique aimed at reducing the incidence of cerebrospinal fluid leak after cerebellopontine angle tumor surgery. STUDY DESIGN Retrospective case review. SETTING Tertiary referral center. PATIENTS All patients undergoing cerebellopontine angle(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)
The role of postoperative radiographic follow-up of patients after acoustic neuroma or glomus jugulare tumor removal is unclear and not standardized. The incidence of both lesions is rare and recurrence thought to be unusual. However, a patient with an acoustic neuroma arising in the same ear afflicted with a glomus jugulare tumor removed 5 years earlier(More)
The results of lateral cranial base surgery for glomus jugulare tumors are gratifying when normal anatomy and function can be preserved. The goal of conservation surgery is to preserve normal ear anatomy and cranial nerve function. In general, conservation surgery is tumor-size dependent. Thus, excellent states of functional recovery depend upon accurate(More)
