Nasal valve collapse - how long should I wait for a revision? (Photo)

I had fess with a rhino septoplasty 4 ish months ago. My nose has since collapsed which surgeon has admitted to, however I didn't really press as to why this happened. I had no breathing issues prior, only constant sinus infections & this is a well known ENT. He's adamant that revision should take place asap however I've heard that 1 year minimum is better so generally seeking advice as to whether such a quick revision is safe. Thanks!
