Zusammenfassung
Bericht über einen ungewöhnlichen Verlauf eines Blutgefäßes in der Cochlea eines Patienten. Das Gefäß zog von der Lamina spiralis ossea unter Durchquerung der Scala tympani bis zur lateralen Wand des Ductus perilymphaticus. In der Region dieses abnorm verlaufenden Gefäßes fand sich ein völliger Haarzellverlust. Beim Patienten bestand während des Lebens ein Hörverlust vor allem bei 2000 Hz mit Ohrensausen.
Summary
An unusual blood vessel in the cochlea of a patient is reported. The blood vessel derives from the osseous lamina spiralis and crosses straight through the scala tympani toward the lateral wall of the perilymphatic duct. In its course a branch derives from this vessel toward the other spiral vessel. In the region of this aberrant vessel a complete hair-cell loss is present. A high tone perceptive loss with a relative dip and tinnitus was found in the same ear during life. The possible cause and effects of this aberrant vessel are discussed.
