Hi all, I had a lateral ceph done which I posted about a few months back in the aesthetics subforum. My question now is basically functional -- is anyone able to tell the size of my airways by looking at my lateral ceph? I can't really tell myself because my jaw makes the area somewhat opaque and I can't tell where the airway starts or ends.

My dentition is completely normal except for a measurement called "U6 - PT Vertical" (I don't know what it means and online research has not been fruitful), the value for which was 7.1 mm whereas a normal value is 18 mm. Does anyone know what this means? Although my SNB angle is normal and my lower jaw is not recessed, some nights I feel I don't sleep well and I wake up in the morning not feeling well rested. It's possible my recessed maxilla could be contributing by creating some nasal airway resistance or by not giving enough room for my tongue causing it to slip back during sleep. Or, I could just have constricted airways independent of either upper or lower jaw issues.
I had a sleep study done and it was normal and showed no apneas, however, I don't know how reliable it is because I didn't sleep very well at the lab and probably didn't have much time in REM sleep anyway. I'll have to re-check the specifics.
I should note that I did have 1.5 glass of wine right before I went to bed and that may very well have caused the sleep apnea or made it worse. What are people's thoughts?
