Professor Pierre Delaere (Otorhinolaryngology section, K.U.Leuven) has in the past decade developed a new surgical technique for larynx reconstruction. In an increasing number of cases, this innovative technique can save the larynx in patients suffering from vocal cord cancer. Patients are able to breathe, swallow and speak normally following the operation, something that was previously impossible since the entire larynx frequently needed to be removed, even if only one vocal cord was affected.
The larynx separates the digestive system and the respiratory system. If the larynx is removed then the separation must be effected in some other way. Persons without a larynx can still eat if the oesophagus is connected directly to the oral cavity. However, this means that breathing through the mouth and nose becomes impossible and a permanent opening (stoma) for the trachea has to be made in the patient’s neck. This is a very conspicuous intervention and results in many problems of adaptation. Speech is still possible using an apparatus placed in the stoma, but the patient must cover the opening with his finger.
Prof. Delaere investigated why the larynx was completely removed in almost every case. In part, this is a result of the complex structure of the larynx itself. If part of the larynx is removed, two main problems arise: new tissue must be found to replace what has been removed, and the supply of blood must be optimal to ensure that the new tissue does not die.

Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
