Results showed that stimulation of the apical region of the cochlea supports a significant degree of speech understanding, and that distributing the contacts over the whole length of the Cochlear implant electrode improves speech perception in quiet and in noise.
Round Window Stimulation with an Implantable Hearing Aid (Soundbridge®) Combined with Autogenous Reconstruction of the Auricle – A New Approach
Combining aesthetic and functional rehabilitation, autogenous reconstruction of a new auricle together with the implantation of an active middle ear hearing aid, coupled to the round window membrane, is a promising new approach.

It is concluded that the application of 250 mg has a greater impact on the inner ear than 125 mg, and the therapeutic dose of prednisolone is not known.
Otosclerosis—an inflammatory disease of the otic capsule of viral aetiology?
A viral aetiology of otosclerosis as an inflammatory vasclar reaction of the otic capsule initiated or caused by the viruses of measles, rubella and mumps is favoured.

Medical, surgical, and technical complications with the COMBI-40.
The first report on complications of cochlear implantation with the COMBI-40 (Med-el, Innsbruck, Austria).
Otosclerosis: a measles virus associated inflammatory disease.
The results support the previously stated hypothesis that otosclerosis is a measles virus associated disease which provokes a local immune response within the inner ear.

Measles virus specific antibodies were detected in all of the perilymph samples from 19 patients suffering from otosclerosis, and the relative amount of these IgG antibodies was much higher than in serum samples of the same patients or inperilymph of control patients.

It is concluded that minimal stimulation of the facial nerve during middle ear surgery could result in a reactivation of HSV-1 in the geniculate ganglion, which may in turn lead to a facial palsy.
Diagnostic Procedures for Detection of Lymph Node Metastases in Cancer of the Larynx
Investigations and review of the literature found that ultrasound-guided fine needle aspiration cytology showed an accuracy of 89% and was in the same range with positron emission tomography (90.5%) and computed tomography scanning (84.9%) and magnetic resonance imaging (85%) was superior to palpation.
