Unilateral acoustic neuromas in childhood without evidence of neurofibromatosis: case report and review of the literature.

A six-year-old female with a unilateral benign acoustic neuroma and no evidence of neurofibromatosis is presented. Review of the literature revealed only 16 cases of unilateral acoustic neuromas in children less than 15 years old. Children often do not appreciate hearing loss when compared with adults. As a result, they often present with larger tumors, thus adversely affecting outcome. The need for early diagnostic tests and a hearing-conservation surgical approach is emphasized. Routine follow-up imaging studies are crucial to rule out the development of a contralateral acoustic neuroma in neurofibromatosis-2 (NF-2).

Myringoplasty in children.

This series examines the results of myringoplasty in children using the overlay technique. Controversy still surrounds the issue of proper timing of surgery on the basis of preoperative assessment of tubal function. Results of this technique in children, using contralateral ear status as the primary predictor of success, found an overall success rate of 78%. Age appears to be a significant factor because children 10 years old and younger were found to have a higher incidence of surgical failures.

Carcinoma of the external auditory canal: an update.

This review is a continuation of the series of 35 cases of carcinoma of the external auditory canal originally reported by the senior author and colleagues. Eighteen additional cases have been evaluated and treated since 1976. Preoperative high-resolution computed tomographic scanning has replaced polytomography, and improved surgical skull base approaches have allowed for extended resections of advanced lesions. A revised classification for local and extensive lesions is presented. The prognosis for localized tumors treated by en bloc resection remains excellent, whereas prognosis for extensive lesions might be more dependent on histologic type and grade of tumor.

Effects of maternal cocaine abuse on the neonatal auditory system.

Eighteen neonates born to cocaine-abusing mothers were tested for peripheral and brainstem auditory dysfunction using auditory brainstem responses (ABR). Their data were compared to ABRs from 18 normal neonates. The ABR data were analyzed to determine if ABR parameters were abnormal in neonates born to cocaine-abusing mothers in comparison to normal neonates. ABRs from neonates exposed to maternal cocaine abuse show prolonged interpeak latencies and prolonged absolute latencies. These abnormalities indicate neurologic impairment or dysfunction that warrants further audiologic and neurologic follow-up.

Management of vertigo in patients with syphilis: is endolymphatic shunt surgery appropriate?

Endolymphatic shunt surgery has been suggested as a means to relieve vertigo caused by syphilis in patients unresponsive to conventional medical therapy. We reviewed results of endolymphatic shunt surgery on vertigo and hearing in six patients with syphilis. We found no relief of vertigo in four patients who qualified for this measure and no improvement in hearing. Histologic review of temporal bones from three patients with syphilitic hydrops revealed syphilitic involvement of the endolymphatic duct system. This may explain why endolymphatic shunt surgery may not be beneficial.

Acute epiglottitis in adults. A review of 48 cases.

Acute epiglottitis was diagnosed infrequently in adults until the late 1960s and early 1970s. Because it is relatively rare, it may present a problem to the physician who sees an adult with sore throat and dysphagia, but does not think of epiglottitis. In this paper, we report our experience with 48 cases of acute epiglottitis in adults between the years 1963 and 1987. A discussion of the diagnosis and treatment of adult epiglottitis is presented. An adult with acute painful dysphagia should be considered to have epiglottitis until the diagnosis is proven otherwise.
