A possible correlation between vertebral artery insufficiency and degenerative changes in the cervical spine

Abstract We studied 130 patients, aged 20 to 81 years, with symptoms of tinnitus, vertigo or dizziness. Radiological examinations revealed degenerative changes in the cervical spines of all patients such as discopathy or osteophytes. Head and neck and neurological examinations ruled out other symptoms apart from vertebrobasilar artery flow insufficiency. The vertebrobasilar arteries were examined by means of a color Doppler ultrasonograph using duplex scanning. The correlation coefficient (CC) defining the relationship between the number of patients with abnormal blood flow and the total number of patients with radiologically confirmed changes in the cervical spine was 41.5%. When patients were separated by age, the value of the CC coefficient increased proportionally according to age, changing from 0 to 79.1%. Use of the Doppler ultrasonograph was found to be a safe and non-invasive diagnostic method that enabled us to assess the influence of degenerative changes in the cervical spine on hemodynamic disturbances in the inner ear and brain stem. Our findings demonstrated a pathological decrease of vertebral artery flow velocity in relationship to degenerative changes in the cervical spine.

Effectiveness of classical chordectomy in the treatment of cancer of the glottis

From 1980 to 1992, 85 patients diagnosed with tumour of the glottis, localized exclusively in the vocal cord area, had undergone surgery. A 90% 5-year survival rate without recurrences had been obtained. Taking into account the cases of life-saving surgery, the percentage of the 5-year survivals amounted to 94%. Considerably better results were obtained by the excision of the entire vocal cord and not just one of its sections (1/2, 2/3 etc.). The degree of deformation of the voice following chordectomy was assessed by means of acoustic and laryngographic methods (Laryngograph Processor PCLX). A 13% rate of irregularity in the functioning of the neoglottis, following surgery, was observed. The Jitter-Shimmer co-efficients were established. The results of the deformation of the voice following chordectomy were presented on the J-S scale and compared with other partial surgeries performed on patients with tumours of the glottis. All of the acoustic and laryngographic findings were presented in the from of mean values most representative of chordectomy.

Ohrmuschelplastik und frische Ohrmuschelverletzung

Einteilung der Fehlbildungen (Klassifizierung) – Dysplasie 1. Grades: Der überwiegende Teil der anatomischen Grundstrukturen ist vorhanden, z.B. abstehende Ohrmuschel, Makrotie, Kolobom (quere Spalte), Tassenohr Typ 1 und 2, kleine Missbildung (Stahlsches Ohr, Darwinscher Höcker, Satyr-Ohr, Lobulusmissbildung) – Dysplasie 2. Grades (Mikrotie 2. Grades): Ein Teil der anatomischen Grundstrukturen ist vorhanden, z.B. schwere Tassenohrdeformität Typ 3 (häufig mit Dystopie), Miniohr (Defizit im oberen, mittleren oder unteren Anteil) – Dysplasie 3. Grades (Mikrotie 3. Grades) und Anotie: Typische anatomische Grundstrukturen sind nicht erkennbar, z.B. rudimentäre Ohrmuschel, völliges Fehlen jeglicher Ohrmuschelstrukturen, häufig mit Atresia auris congenita
