Report is made about a patient, with a malignant first sized teratoma of the nasillary sinus, which extended to the orbit. The tumor has been removed surgically one year before and the patient is free of symptoms.
Report on two cases of local amyloid-tumors of the larynx. The microsurgical resection resulted in excellent functional recovery. One year after surgery no signs of recurrency were observed.
A case of invasion of the human ear by the German cockroach Blattella germanica (L) IN Mash'had, Khorassan, Iran is described. As far as the Author is aware this is the first such case recorded and published from Iran.
A patient studied preoperatively by a neuro-otological test battery showed signs of an extensive cerebellopontine angle tumour. During the operation dense fibrotic tissue was found extending from the choroid plexus to the right acoustic nerve, which was freed and thus decompressed. Postoperatively, low frequency hearing improved markedly in the right ear. In contrast to the well-known documented cases of successful decompression of the optic nerve it has not been possible up to now to achieve a successful outcome in similar procedures on the acoustic nerve. In the described case the fibrotic lesion had obviously just caused reversible damage to the myelin sheaths of the eighth nerve, which can be interpreted as "neurapraxia" (Seddon, 1943). Further investigations in regard to the systematic elucidation of possibly reversible damage to the acoustic nerve are currently being performed at the IInd ENT department of Vienna University.
It is reported about myography on testpersons with normal vestibular function as well as on patients after operativ dissection of the VIII. nerve, neuropathia nerv. vest. and M. Menière. On the base of these findings it is supposed that myography proofes to be a useful help in the judgement of the specific influence of the vestibular organs on the motoric system. The myographic changes of the muscular activity after caloric stimulation give exact information about the entire vestibular system and especially about the vestibular-spinal-pathways. The best way of testing the vestibular activity is performed on musculars with symmetric, simultaneous and reziproke intented innervation, f.i. on the sternocleidomastoidei muscels in slight deflected position of the head. Most significant for the vestibular influence are an increase of the base-activity and the appearance of groups of potentials which are related to the vestibular stimulus in time and intensity.
