I must assume your subject line is an error. The vestibular system is the balance system in the inner ear. I assume you meant the velopharyngeal system.
That said you mention that he has inconsistent nasality in connected speech. And you mention nasal emission oral stops. Any emission on fricatives? conventional wisdom is that it would a learned behavior only if it happens consistently on one or two sounds. otherwise it is likely a problem with the mechanism requiring either surgery or prosthetic management. There are some documented cases of VPI following adenoidectomy. That's why many physicians are reluctant to remove the adenoids.

Subject: [phono-tx] Re: Impaired vestibular system?
His connective speech is simplified, with ommissions and assimilation. There is some nasal escape of oral stops which is audible and visible both at sentence and word level. He is responding well to cues to reduce the rate of speech and introduce prosody which is already making a huge difference to his intelligibility. No one posted any answers regards my question about an under developed vestibular system so i'm picking theres nothing obvious underlying that i am missing.
He is due to be reviewed by ENT in the next few months, if the nasality doesn't improve with therapy prior to this appt is there any way of knowing whether the nasal escape is due to space left from the adenoidectomy or something unrelated like VPI.
Thanks again
