Conclusion: “In conclusion, we measured pharyngeal parameters in a large number of normal subjects using the acoustic reflection technique with air breathing. The pharyngeal compliance was greater in the men than in the women, and it increased with age only in the men. The pharyngeal size in the lying positions did not change with age and was not significantly different between the genders. These data indicate that the assessment of pharyngeal compliance could contribute to the elucidation of sleep-related disorders of breathing.”
