Abstract

The aim of this study is to evaluate the efficacy of uvulopalatopharyngoplasty and the corresponding postoperative airflow. Eleven patients diagnosed with obstructive sleep apnea syndrome who complained of snoring and apnea were enrolled in this study. Computational fluid dynamics (CFD) was implemented. CFD could be accomplished in nine cases. Airflow analysis was not possible in cases with a high respiratory event index (REI) score. Before surgery, stenosis was identified in the oropharynx and epiglottic area. And the airflow velocity and pressure were found to have significantly decreased in the oropharynx postoperatively, while in the epiglottic area, those data had increased postoperatively in some cases. The velocity and pressure of the oropharynx are related to REI score. From the CFD analysis, airflow analysis is important for evaluating the apnea state. It is suggested that the postoperative function can now be predicted preoperatively.

Nur selten ernste Komplikationen bei endoskopischer Sinuschirurgie

Etwa 3% der Menschen mit einer endoskopischen Nasennebenhöhlenoperation entwickeln ausgeprägtes Nasenbluten. Andere Komplikationen, wie Verletzungen des Nervus opticus oder eine Meningitis, treten nur äußerst selten auf, legt eine Registeranalyse nahe.

Sicheres Protokoll zur Entfernung von Fremdkörpern im Gehörgang

Ein erfahrener HNO-Arzt und Pädiater stellt ein Protokoll vor, mit dem Fremdkörper bei Kindern und Jugendlichen aus dem äußeren Gehörgang erfolgreich entfernt werden können. Im Mittelpunkt stehen dabei die sichere Fixierung des Kindes sowie der Einsatz eines Operationsmikroskops.

Ärztinnen überholen Ärzte bei Praxisgründungen

Bei Praxisgründungen haben inzwischen die Frauen deutlich die Nase vorn: Seit zehn Jahren wagen laut apoBank mehr Ärztinnen als Ärzte den Schritt in die Selbstständigkeit. In puncto Finanzierung sind sie aber vorsichtiger als die männlichen Kollegen.

Ambulante Behandlung darf länger dauern als stationäre

Ambulante Behandlungen haben Vorrang vor stationären - auch wenn diese läner dauern. Das hat das Bundessozialgericht klargestellt. Konkret ging es um Liposuktionen der Ober- und Unterschenkel.
