Abstract

Background

Conservative treatment, including observation and closed treatment, as well as open reduction and internal fixation are existing options for treating condylar process fractures. Extraoral approaches are widely preferred for open reduction and internal fixation. Transoral access for condylar base and neck fractures is not yet commonly used as it is technically demanding and requires special equipment.

Purpose

In this study, the transoral endoscopically assisted approach is described, and its outcomes and complications were investigated. Imaging data and clinical records of 187 patients with condylar process fractures, treated via endoscopically assisted transoral approach between 2007 and 2017 were analyzed. Parameters included diagnosis and fracture classification, treatment, osteosynthesis configuration and postoperative complications.

Results

Early complications, including infection, transient postoperative malocclusion, pain and limited mouth opening, occurred in 35 patients (18.7%). Late onset complications, such as screw loosening were documented in only 4 patients (2.1%). Revision surgery following postoperative 3D imaging was required in only 3 cases (1.6%). Fragment length ranged from 15.5 to 38.3 mm. In 57.7% of patients with condylar fragment length < 20 mm, a single osteosynthesis plate was used, with no elevated complication rate. Two osteosynthesis plates with 4 screws each was used as standard in longer fragments.

Conclusion

Endoscopically assisted transoral treatment of condylar process fractures is a reliable, yet technical demanding technique. It allows for reduction and fixation of fractures with a condylar fragment length of > 15 mm with low postoperative complication and revision rates.

Echinokokkose medikamentös behandeln oder operieren?

06.05.2024 DCK 2024 Kongressbericht

Die Therapie von Echinokokkosen sollte immer in spezialisierten Zentren erfolgen. Eine symptomlose Echinokokkose kann – egal ob von Hunde- oder Fuchsbandwurm ausgelöst – konservativ erfolgen. Wenn eine Op. nötig ist, kann es sinnvoll sein, vorher Zysten zu leeren und zu desinfizieren. 

Recycling im OP – möglich, aber teuer

05.05.2024 DCK 2024 Kongressbericht

Auch wenn sich Krankenhäuser nachhaltig und grün geben – sie tragen aktuell erheblich zu den CO2-Emissionen bei und produzieren jede Menge Müll. Ein Pilotprojekt aus Bonn zeigt, dass viele Op.-Abfälle wiederverwertet werden können.

Im OP der Zukunft läuft nichts mehr ohne Kollege Roboter

04.05.2024 DCK 2024 Kongressbericht

Der OP in der Zukunft wird mit weniger Personal auskommen – nicht, weil die Technik das medizinische Fachpersonal verdrängt, sondern weil der Personalmangel es nötig macht.

Nur selten Nachblutungen nach Abszesstonsillektomie

03.05.2024 Tonsillektomie Nachrichten

In einer Metaanalyse von 18 Studien war die Rate von Nachblutungen nach einer Abszesstonsillektomie mit weniger als 7% recht niedrig. Nur rund 2% der Behandelten mussten nachoperiert werden. Die Therapie scheint damit recht sicher zu sein.

S3-Leitlinie „Diagnostik und Therapie des Karpaltunnelsyndroms“

Karpaltunnelsyndrom BDC Leitlinien Webinare
CME: 2 Punkte

Das Karpaltunnelsyndrom ist die häufigste Kompressionsneuropathie peripherer Nerven. Obwohl die Anamnese mit dem nächtlichen Einschlafen der Hand (Brachialgia parästhetica nocturna) sehr typisch ist, ist eine klinisch-neurologische Untersuchung und Elektroneurografie in manchen Fällen auch eine Neurosonografie erforderlich. Im Anfangsstadium sind konservative Maßnahmen (Handgelenksschiene, Ergotherapie) empfehlenswert. Bei nicht Ansprechen der konservativen Therapie oder Auftreten von neurologischen Ausfällen ist eine Dekompression des N. medianus am Karpaltunnel indiziert.

Das Webinar beschäftigt sich mit Fragen und Antworten zu Diagnostik und Klassifikation sowie Möglichkeiten des Ausschlusses von Zusatzverletzungen. Die Referenten erläutern, welche Frakturen konservativ behandelt werden können und wie. Das Webinar beantwortet die Frage nach aktuellen operativen Therapiekonzepten: Welcher Zugang, welches Osteosynthesematerial? Auf was muss bei der Nachbehandlung der distalen Radiusfraktur geachtet werden?
