Middle fossa approach for acoustic tumor removal. 1992.

The middle fossa approach is useful for the removal of small acoustic tumors when hearing preservation is possible. This approach provides complete exposure of the contents of the internal auditory canal and positive facial nerve identification. Because access to the posterior fossa is limited, the middle fossa approach is most appropriate for tumors with less than 5 mm extension into the cerebellopontine angle. With the introduction of gadolinium-enhanced magnetic resonance imaging, very small acoustic tumors are diagonosed more frequently, and the middle fossa approach is well-suited for the removal of these tumors.

A practical cochlear implant for India.

The present studywas done to evaluate the performance of short electrode, single channel, low cost cochlear implant working with analogue strategy.Both prelingual and post lingual patients were selected for the study. Results were assessed using standard protocol established by us evaluation of these patients in the local languagues.For two years follow up, overall results for post lingual patients are satisfactory.Incase of prelingual patients results are very encouraging as well.If we consider the cost v/s. the performance, these low cost implents can be the ideal implant for the Indian patients.

Menière's disease: management and theory

In view of the spontaneous remissions and exacerbations of Menière's disease, claims are often made that it can be cured with any medication, while others feel that nothing works. This article attempts to review the available information on this problem in order to obtain consistent results. The elements for a precise diagnosis, including a detailed clinical history, hearing tests, electronystagmography, petrous pyramid X-rays and laboratory studies, are presented. The course of Menière's disease and the medical and surgical treatments are evaluated. The pathophysiology of the disease is discussed, as well as the author's personal experience.
