I'd swear I know if it'd have happened about a month ago. Same looking damage and same looking TM. If nothing internal if screwed you can order the casing and such. On 2nd look, take it to a TM repair place.
Sorry bout being in a shite mood last weekend but you can get case reasdonable online. Friend of mine had a similar accident. His has been zip tied for two years. No problem with direction with his though. Cool now?
