Secondary Haemorrhage following Tonsillectomy

Tonsils are two oval-shaped pads of tissue located at the back of the throat. Tonsillectomy is then the surgical term used to describe the removal of the tonsils. Infected or enlarged tonsils may lead to chronic or recurrent sore throat, bad breath, abscess, airway obstruction, difficulty in swallowing and snoring. This procedure helps to reduce infection and inflammation of the tonsils which is known as tonsillitis, as well as to resolve breathing problems. Like any other surgeries, this procedure has risks such as bleeding can occur in the first 24 hours following the operation (primary), or later (secondary).

KTPH maintains a high vigilance on its quality of surgical techniques and management of patient after Tonsillectomy. This indicator serves to reduce patients’ risk through active monitoring of post-tonsillectomy bleeding complications. From January 2016 to June 2018, the mean rate of secondary haemorrhage following tonsillectomy was 5.3% (n=12), which is comparable to the international rates of 10%.
