Possible anatomical base of snoring.

Variations of the medial and inferior choanal limits may facilitate snoring. These are: 1) short vomer without crista choanalis vomeris and adaptational formations, 2) extremely concave posterior margin of the hard palate leading to disproportion between the muscular and aponeurotic part of m. tensor veli palatini and hence to a flabby soft palate especially during sleep, and 3) neonatal relation of the height and width of the choane resulting in a very large choanal region instead of relative reduction of choanal width compared to its increasing height. All these variations result in a flabby soft palate especially during sleep and may lead to formation of whirles of inspired air and snoring.

[Concentration of trace elements in the inferior turbinates and in the nasal septum of the human]. / Konzentration der Spurenelemente in der unteren Nasenmuschel und im Septum des Menschen.

The trace elements in 47 inferior turbinates (concha nasalis inferior) and in the nasal septum were examined by means of synchrotron radiation, spectroscopy of characteristic x-rays, and "sub-micron elemental mapping with the Oxford scanning proton microprobe", and the results compared. Both first methods displayed an age-dependent reduction of Zn and an increase of Pb concentration. In some specimens the As concentration was very high. The disposition of all elements except Zn, As and Fe was uniform. Zn and As were concentrated on the surface of the septum and Fe in the region of vascular channels.

Analysis of trace elements in the human labyrinth by using proton microprobe.

The concentration of zinc in the spiral tract is age-dependent. The accumulation of zinc starts at the bone surface towards the fundus of the internal auditory meatus and continues throughout the whole thickness of the separating wall to reach in advanced age the bone surface towards the basal coil of the cochlea. The concentration of calcium decreases with age. These findings prove our previous histological and densitometric as well as macroscopical investigations of this region.

[An attempt at explaining ophthalmoplegia and amaurosis following videctomy (author's transl)]. / Ein Erklärungsversuch der Ophthalmoplegie und Amaurose nach der Videctomie.

The unexplained rare cases of amaurosis and ophthalmoplegia after videctomy can be explained by the rare anomalous origin og the a. ophthalmica from the a. meningea media instead of a. carotis interna.

[Lymph node in the facial canal causing facial spasm (author's transl)]. / Lymphknoten im Fazialiskanal als Ursache des Gesichtskrampfes.

The presence of a lymph node in lower enlarged portion of facial canal causing facial spasm is described and illustrated. As contrast to this case, a case of extreme narrowing of the canal causing palsy of the facial nerve is mentioned.

[Aequidensitometrie of the labyrinthic capsule with special regard of the bottom of the internal auditory meatus]. / Aquidensitometrie der Labyrinthkapsel mit besonderer Rücksicht des Bodens des inneren gehórganges

It has been proved by densitometry that the thickness of the separating wall between the basal coil and the fundus of the internal auditory meastus as well as the thickness of the labyrinthic wall increase with age. The mineral contents is simultaneously reduced. The diameter of the cochlear canal is also reduced with age. These facts have been demonstrated by aequidensitometry and by summation color pictures of aequidensites.

Further contribution in the densitometric study of the labyrinthic capsule with special reference to the bottom of the internal auditory meatus.

The quantity of minerals in the labyrinthic capsule of the basal coil and of the separating wall facing the internal auditory meatus in different life periods was determined by the densitometric method. The quantity of minerals is reduced in the labyrinthic capsule and in the separating wall in spite of the bone apposition and increasing thickness of the separating wall.
