[The Difficult Airway with Tracheostomy - Manufacturing of an Individualized Tracheal Tube with Modern Imaging and 3D Printing].

Case discussion of a 51-year-old female patient with ventilator dependency due to Charcot-Marie-Tooth-Hoffmann syndrome (HMSN I) and cervical spinal fusion with complex tracheal canula management. Following 16 years of noninvasive ventilation due to chronic hypercapnic failure with 24 hour dependency on the ventilator, an elective surgical tracheostomy and switch to invasive ventilation was carried out. Because of severe cervical scoliosis, common tracheal canulae could not provide an adequate fit. With development of a 3D model according to the CT scans of the patient, an individualized tracheal tube was customized that provided excellent ventilatory results and the ability to speak during invasive ventilation.
