Novel method for the rehabilitation of the voice of patients who have undergone laryngectomy

26.10.2004


The voice laboratory at the University of Navarre University Hospital has designed a novel and efficient protocol to evaluate and rehabilitate the voice of patients who have undergone laryngectomy. This involves a monitoring procedure based on patterns of phonatory flow. The study forms part of the PhD thesis by Dr Francisco Vázquez de la Iglesia. The title of the work is “Physiological Bases of the Pharyngoesophageal Segment. Characterisation of the erigmophonic voice as a function of its acoustic and aerodynamic parameters”.



Total laryngectomy is a surgical technique involving the radical extirpation of the larynx in patients suffering from advanced-stage cancer. According to Dr Vázquez, “these patients lose their capacity for oral communication, which greatly influences their quality of life. The most usual procedure for recovering the voice is the use of the esophagic voice. However, there is no diagnostic procedure enabling us to assess this quality of voice or that provides concrete rehabilitation measures that help to improve it”.

Description


The voice laboratory at the Ear, Nose and Throat Department at Navarre University Hospital has designed a protocol based on acoustic and aerodynamic parameters involved in the esophagic voice. “We conceived and adapted a specific instrument which has enabled an objective exploration method which helps us to better understand the complex process of the esophagic voice. By means of spectrographic parameters (quality of voice) and quantitative (pressure, flow, frequency), we can objectively define the different types of esophagic voice and rehabilitate it by means of positive feedback systems”.

One of the main interesting things about this research work is its immediate application to clinical practice, suitable for both diagnosing alterations in the esophagic voice as well as facilitating its rehabilitation. Moreover, it can be used for application in other rehabilitation procedures such as phonatory prothesis, electrolarynx, or even a number of surgical procedures on the pharyngoesophageal segment.

According to Dr Vázquez, “all patients subject to a total laryngectomy can benefit from this instrumental method, but above all those who, despite speech therapy, do not obtain a suitable esophagic voice. Currently, up to 70% of these patients do not manage to speak with an optimum voice.”

In the study, 33 patients who had undergone laryngectomy participated.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
