Head and neck cancer is more common than you think

Source: www.irishtimes.com Author: Jamie Ball Well over 1,000 people in Ireland are diagnosed each year with cancers of the head and neck, with almost three-quarters of cases being attributed to smoking and alcohol. Yet this pernicious form of cancer very often goes under-reported, or sufficient heed isn’t paid to the warning signs that, if caught early, may be the difference between life and death. This is why July 27th will mark the third World Head & Neck Cancer day, taking place across 53 countries. The 2017 National Cancer Strategy highlights the importance of prevention, detection and diagnosis, and education and awareness is key for early recognition of the disease. According to James Paul O’Neill, Prof of Otolaryngology, Head and Neck Surgery in Beaumont Hospital, Dublin and the Royal College of Surgeons in Ireland, there can be many different types of cancers within the head and neck, each with their own tissue characteristics and biological behaviour. “Cancers may develop in several areas of this region, including the mouth, throat, larynx (voice box), glandular tissue (thyroid), salivary tissue (parotid gland), lymphatic tissue, nose, sinuses and skin. Patients have a large variety of symptoms and signs according to the subsite of the disease,” says O’Neill. He says surgery incorporates many different techniques and skills, as the region has essential functional roles, such as talking, breathing, smelling, hearing, chewing and swallowing. “We are now in the age of highly-specialised technological innovations. There is a drive towards minimally invasive surgery because we can perform the [...]

Novel one-step system for restoring voice in throat cancer patients

This tool will then be inserted into the cannula so that it can be injected into the patient's fistula according to the length required, using the calibration on the cannula.

Patients who have lost their voice box through disease such as throat cancer may be able to speak immediately after a procedure to create a small opening at the throat. A novel system developed through an Engineering-in-Medicine project led by Dr Chui Chee Kiong, NUS Department of Mechanical Engineering, and Dr David Lau, Consultant Ear, Nose & Throat (ENT) Surgeon at Raffles Hospital, cuts down a two-week duration before patients can speak, to about 10 minutes after the initial procedure. People who undergo laryngectomy and lose their voice box can recover approximately 80 per cent of normal speech by having a voice prosthesis fitted into an opening or fistula between the trachea (windpipe) and esophagus (food pipe). To speak, the patient covers the stoma (breathing opening in the neck) with his or her thumb and forces air through the prosthesis into the esophagus and out through the mouth. Before the prosthesis can be inserted, the doctor needs to make a small puncture (tracheo-esophageal puncture or TEP) in the wall between the trachea and esophagus. During the puncture, a guide-wire is inserted into the [...]
