A Novel Method for Secondary Mandible Reconstruction to Re-Achieve a Native Condyle Position Comprising a New Design for Cutting Guides and New Positioning Devices.

Secondary mandibular reconstruction using fibular free flaps (FFF) is a technical challenge for surgeons. Appropriate operation planning is crucial for postoperative quality control and is notably necessary for the (re-) achievement of a physiological condylar position, and the sensible expansion and shaping of the transplant. Computer-assisted planning may help to reconstruct mandibular defects in a patient-specific and precise manner.

Drug-induced Defibrinogenation as New Treatment Approach of Acute Hearing Loss in an Animal Model for Inner Ear Vascular Impairment.

Objective: Disturbance of cochlear microcirculation is considered to be the final common pathway of various inner ear diseases. Hyperfibrinogenemia causing increased plasma viscosity is a known risk factor for sudden sensorineural hearing loss and may lead to a critical reduction of cochlear blood flow. The aim of this study was to evaluate the effect of a substantial reduction of plasma fibrinogen levels by drug-induced defibrinogenation for the treatment of acute hearing loss in vivo.
