I have a surprisingly similar anecdote! Face-planted skating during finals week in my first year at university. My first memories are some hours later in the waiting room at a hospital that my friends had brought me to, holding a notepad with some hand-written responses to "What happened?" and "Where am I?" because my friends had gotten tired of repeating answers to the questions I'd forget having asked every few minutes.

I only had a couple finals remaining, and my profs gave me deferrals as soon as they saw the state of my face when I showed up at their offices. Wrote them a week or two later without issue.

Didn't notice any lingering mental issues, though it's now been nearly two decades and a nerve in my face still feels a bit funny, and my current dentist pointed out that it seems like I've done some damage to some of my jaw tendons at some point. (But as it doesn't cause me problems, didn't recommend treatment.)
