[|Human|] My wife underwent tracheostomy in August due to Respiratory failure. Currently she is on 1 litre O2 support. A CT scan and virtual bronchoscopy has been done recently which states s/o infection. Doctor has advised Wysolone. The tracheostomy site has developed GRANULOMA causing 70 % airway blockage as per her Discharge Card issued in the month of Augusf. Please advice further treatment.
[|AI|]  Hello and Welcome to Ask A Doctor service. I have reviewed your query and here is my advice. Chronic tracheostomy is often leaded to infection and granulation at the site of tube. So she needs to remove all this granulation tissue through surgery. She will need new tracheostomy tube insertion. Proper tracheostomy care is must prevent granulation tissue formation and infection.  Hope I have answered your query. Let me know if I can assist you further.
