Emphasising on the need for awareness on voice care among teachers, Dr M Kumaresan, an ENT surgeon from Chennai, said around 20 per cent of the teachers with over 10 years of professional experience are likely to get vocal cord disorders.
He was speaking at a camp for teachers at the District Science Centre on Saturday. He said, a hoarse voice could result due to various reasons, including talking too much, screaming or smoking.
This in turn could lead to problems such as vocal cord paralysis, swelling and laryngitis.
