Anyone have an experience in removing granulation tissue from the mouth and preventing its recurrence? I have had three excisions since January 2014 of a prune-sized granulation tissue next to the tongue (partial glossectomy for oral cancer 15 years ago, followed by radiation). Wound site is getting smaller each time, but it doesn't heal properly - leading to granulation re-growth. Silver nitrate applications were done on several occasions, pre- and post-operative. Any suggestions on how to stop this cycle? Thank you.
