Zur Physiologie des Labyrinthes der Tanzmaus

Abstract: 1. Die Tanzmause reagiren auf keinerlei Schalleindrucke. 2. Sie besitzen ein mangelhaftes Vermogen, das Korpergleichgewicht zu erhalten. 3. Sie haben keinen Drehschwindel. 4. Sie verhalten sich der galvanischen Durchstromung des Kopfes gegenuber wie normale Thiere.

Histologic picture of inherited nerve deafness in man and animals.

Abstract: HEREDITARY factors play an important role in the cause of nerve deafness. A thorough knowledge of their mode of action and their clinical and anatomic manifestations is essential for the proper recognition, management and prevention of many forms of hearing loss. The question of prevention is of particular importance, since hereditary deafness has not been and is not likely to be amenable to any kind of therapy. In the last twenty years knowledge in this field has greatly increased, particularly because of the extensive research done by animal geneticists. The published material is, however, scattered throughout a large number of journals, monographs and dissertations, some of which are hardly accessible for the average reader. Only very few of the reports have appeared in the American otolaryngologic literature, and a comprehensive up-to-date review of the findings is entirely missing. In this paper it has been attempted not only to report the

Zur Pathologie und pathologischen Anatomie der kongenitalen Taubheit

Abstract: Die Kenatnis der Anatomie der angeborenen Taubheit hat in neuerer Zeit dureh eingehende, histologisehe Untersuehungen eiae wesentliche Bereieherung erfahren. Hier sind die Arbeiten yon P o l i t z e r , S e h e i b e , S i e b e n m a n n und 0 p p i k o f e r zu nennen~ die sieh si~mflieh aaf mensehliehes Material beziehen. Nieht minder wiehtig hat sich die Untersuehung yon Tieren mit angeborenen Labyrinthanomalien erwiesen (taube Katzen [Alexander])~ Tanzmause (A lexande r und Kre id l ) , wobei man imstande ist~ lebensfrisehe 0bjekte in grSl~erer Zahl zu verarbeiten und deren Befunde mit denjenigen yon Mensehen in volle Analogie gebraeht werden kSnnen. Wie sehr wir dureh diesen Umstand bei der anatomisehen Untersuehung mensehliehen Materiales gef6rdert werden~ ist aus der kiirzlieh ersehienenen Arbeit yon 0 p p i k o f e r ersichtlieh und geht aueh aus meiner folgenden Mitteilung hervor.

Malformations, anomalies, and vestigial structures of the inner ear.

Abstract: ANOMALIES and malformations of the inner ear are uncommon. The majority of them are found either together with abnormalities of the external and middle ear, in cases of so-called congenital atresia, or, as a rule, without other malformations, in inherited nerve deafness. The latter abnormalities have been reviewed in an earlier paper (Altmann1). The structures discussed in this paper are primarily of interest to anatomists and embryologists. Certain anomalies of the osseous capsule of the labyrinth have, however, lately aroused considerable interest among otologists because of their possible relationship to the development of otosclerotic foci. MEMBRANOUS LABYRINTH In discussing malformations of the membranous labyrinth, the phylogenetically older pars superior will be reviewed first. Variations in the mode of origin of the endolymphatic duct from the utricle and saccule (Bast2; Bast and Anson3) should be noted. In about 83% of the cases observed, the angle between the utricular
