Perilymphatic gusher and stapes surgery. A predictable complication?

The cases of 3 patients who had 'perilymph gushers' following stapes surgery are reported. The similarities in their clinical histories and examinations are discussed. All 3 were males and had progressive mixed deafness presenting in early childhood. Polytomography revealed anomalies in both the vestibule and internal auditory meatus in 1 patient; the stapedial reflex was unexpectedly large in all 3. Further preoperative evaluation of these features in other patients and patients affected by the X-linked deafness syndrome is indicated in order to assess the validity of the above criteria.

Immunology of the inner ear: response of the inner ear to antigen challenge.

The relationship of the inner ear to host immunity and the immunoresponsiveness of the inner ear to antigen challenge were investigated. A radioimmunoassay was used to quantitate antibody titers to keyhole-limpet hemocyanin generated in the serum, perilymph, and CSF of guinea pigs following systemic or inner ear immunizations. The results of these experiments demonstrate (1) the blood-labyrinth barrier is analogous to the blood-brain barrier with respect to immunoglobulin equilibrium, (2) the inner ear is capable of responding to antigen challenge, and (3) the inner ear is an effective route for systemic immunization.

Fluid pathways in temporal bones.

Five temporal bones were serially sectioned and studied concerning spread of erythrocytes and blood-derived precipitate in patients who died from subarachnoid hemorrhage. Erythrocytes followed the natural pathways--the cochlear aqueduct, the cochlear, vestibular, facial and glossopharyngeal nerves, and were demonstrable in the inner ear fluid spaces. The temporal bone marrow spaces were also filled with erythrocytes, particularly in the hypotympanal area. In the microimmunoelectrophoresis, no specific precipitation lines formed between the anti-CSF serum from rabbits and middle ear exudate from human ears with acute otitis media. Although, in animals, middle ear spaces have been shown to be connected to the middle ear space this does not seem to apply to human ears, and CSF fluid components are not involved in the formation of middle ear exudate.
