Believe it or not, throat
I wouldn't be surprised if the increased blood pressure could cause a brain aneurysm to rupture. So, that's similar to your head exploding.
With nowhere to escape, the pressure ripped through the soft tissue, and although rare and unusual, they say others should be aware of the danger.
Trapping a sneeze could also damage the ears or even rupture a brain aneurysm, they warn in journal BMJ Case Reports.
Not what i expected, but terrifying.
This is the reality of parenting nobody ever warna you about
It would probably rupture your ear drums.
Might come out of your eyes. Especially if you're able to keep your eyes open during the sneeze.
If I recall correctly, the MythBusters tested "sneezing with your eyes open", and the sneeze does not come out your eyes.

Definitely the ears.
Or eyes.
