Something stuck at the very back of the nose?

This patient had the sensation of food sticking in the back of her nose when inadvertently coughing or sneezing whilst eating. Initially I was sceptical but when examining from below with the HD endoscope I could clearly see small adenoids that had deep fissures within, where I could easily see food trapping on occasion - see photo. The treatment would probably be a form of adenoidectomy under general anaesthetic.
