WHAT IS A TRACHEOSTOMY? According to the UK's National Health Service website, a tracheostomy is a surgical opening in the wall of the trachea (windpipe) to facilitate ventilation. The opening is usually maintained by use of a tracheostomy tube. A tracheostomy may be created for a number of reasons - including to deliver oxygen to the lungs when a person is unable to breathe normally after an injury or accident. Or it can be created because their muscles are very weak. It can also allow a person to breathe if their throat is blocked - this can be caused by a swelling, a tumour, or something stuck in their throat and to reduce the risk of food or fluid going into the lungs. He wrote on Facebook: 'Thank you all for your love and support. There's a rumor I'm unwell again and in hospital which is totally untrue. 'I was in to verify I have no tumor or infection of any kind which was verified by the very caring experts at UCLA.' This was the third time this year that Kilmer - a Christian Scientist - has denied he is suffering from cancer. However, his most statement does concede that he has been undergoing tests for a tumor - something he initially denied when he was admitted to hospital coughing up blood back in January.

'According to a family friend and spokesperson, the doctors are encouraged by his progress and are hopeful that Mr. Kilmer will make a full recovery.' Later, in a Facebook post, Kilmer clarified: 'I have not had a tumor, or a tumor operations, or any operation … I had a complication where the best way to receive care was to stay under the watchful eye of the UCLA ICU.' He went on: 'Friends have assisted who know my spiritual convictions and have been most sensitive and kind for the extra effort in making sure there’s minimum gossip and silly talk.'
