A retrospective study was conducted to analyse videokymographic fi ndings from patients who underwent vertical frontolateral laryngectomy with reconstruction using a sternohyoid muscle fl ap. Overall, 22 patients with T1b and T2 glottic tumours and more than one year of follow-up were studied. Two experienced observers analysed the recorded videokymographic data. A cross-sectional descriptive d...

OBJECTIVE To characterize tissue destruction after CO(2) laser-ablation of the vocal cords with the use of optical coherence tomography (OCT). STUDY DESIGN AND SETTING OCT was used to image fresh porcine vocal cords after laser ablation. OCT and histology estimates of the ablation crater dimensions and the depth of thermal injury were obtained. RESULTS The vocal cord substructures up to 2.2...

The human vocal cord is treated as an elastic material capable of propagating compressional, shear, and surface waves. A mathematical formulation for commonly observed vibrational modes is developed. This includes horizontal as well as vertical tissue displacements. Current vocal cord models are discussed and evaluated in terms of their ability to describe adequately the vibrational degrees of ...

INTRODUCTION Although embryonal rhabdomyosarcomas (ERMS) represent the most common (50% - 60%) clinical form of rhabdomyosarcoma, these are extremely rare in adult's vocal cords. To date, only five cases of laryngeal ERMS have been reported in adults and only one of them involved the vocal cords. CASE PRESENTATION Herein, we reported a case of a 22-year-old woman diagnosed with ERMS, T1N0M0 s...

We have developed a biomechanical vocal cord model for an anthropomorphic talking robot—the Waseda Talker Series. The model mimics the biomechanical structure of human vocal cords and is made of a soft rubber called Septon. It is able to reproduce vocal cord vibrations of the normal (modal) voice in a form similar to the human. We also developed a neural network based model for controlling the ...
