Mundance,

My sister lost most of her ability to swallow, but not like your dad, after surgery). Her tumor was on the carotid artery, and as it grew she began to lose her ability to swallow. Can't help you with advice on your dad's recovery of his swallowing ability, hope the physical therapy is successful. My sister found having a portable suction machine made it so much easier for her to deal with her inability to swallow. Especially when she was going through radiation. It was helpful when she vomited too. The PEG will be a lifesaver, until he learns to swallow again. My best wishes to you both,

Nancy
