Abstract

A total of 187 patients with a suspected intracranial expansive process were studied at the Otolaryngological Hospital, University of Helsinki, in co-operation with the Department of Neurosurgery. After a complete otoneurological and neurosurgical examination 126 of them were found to have an expansive process. The involvement could be neither excluded nor confirmed with certainty in 13 cases, and in 48 the possibility of an expansion was excluded completely. The material included 58 acoustic neurinomas, 52 of which were verified histologically. The otoneurological finding supported the diagnosis of acoustic neurinoma in 53 (91 per cent) cases. In the other cases of expansive processes of the posterior fossa, 2(5 out of 39 (67 per cent) displayed symptoms suggestive of expansion of the posterior fossa. Otoneurological symptoms indicative of expansion were established in 8 (28 per cent) out of 29 cases with an expansive process external to the posterior fossa.

An der Universitäts-Ohrenklinik des Zentralkrankenhauses von Helsinki warden in Zusamnienarbeit mit der ncurochirurgischen Klinik 187 Patienten wegen Ver-dachts eines expansiven, intrakraniellen Prozesses untersucht. Das Ergebnis der Untersuchung zeigte, dass bei 126 Patienten ein expansiver Prozess mit Sicher-heit anzunehmen war, bei 13 Patienten ein derartiger Prozess bezweifelt werden musstc, und in 48 Fällen die Möglichkcit des Vorliegens eines expansiven Prozesses ausgeschlossen werden konnte.

Das Material entbält 58 Akustikusncurinonie. Bei 53 Fällen (91%) liat die otoneurologische Untersuchung die Diagnose der Akustikusneurinome gestützt. Von anderen expansiven Prozessen der hinteren Schädelgrube (39 Fälle) zeigten 26 (67%) Symptome, die mit Sicherheit auf einen expansiven Process hinwiesen. Ein expansiver Prozess ausserbalb der hinteren Schädelgrube lag bei 29 Patienten vor, wobei 8 (28%) von diesen otoneurologische Symptome zeigten, die auf eine Expansion hinwiesen.
