Abstract
This study evaluated whether substantial airflow resistance changes occurred by changing jaw position in normal and snoring subjects. A case-control design was utilized to assess group differences. Subjects included 11 snoring patients and 10 non-snoring subjects. Airway resistance was assessed using a whole body plathysmograph. Subjects in this study had their mouth opening standardized to a position of 7 nun of vertical separation and the resistance was measured under the following conditions: normal jaw position and 2/3 maximum protrusive jaw position.
The results were as follows:
1. The airway resistance was higher in snoring group than in non-snoring group.
2. Both groups had a significant decrease in their airflow resistance upon jaw protrusion.
In conclusion, these data document that airflow resistance can be significantly influenced by jaw positioning. !Moving the jaw in a protrusive position produced reduction of resistance.
