A "friend" of mine had a mucocele removed from his lower cornet playing lip today. A mucocele is a pea-sized cyst caused by a blockage of a minor salivary gland, possibly due to trauma by playing brass. He currently has three dissolvable sutures in his lip and has been advised no playing for ten days. Has anyone else had a friend with a similar problem. How long did it take them to recover and did they recur? Were there any problems afterwards. He did ask the specialist whether he would be able to hit top C's afterwards and the specialist said yes. Interesting as he couldn't before the op.
