Results The OSAS patients had relatively narrow nasopharynges than matched controls in the following items: the sagittal size, transverse size, section area and volume. The measured sagittal size of the nasopharynx was closely related to AHI and Lown SaO2, and the volume of nasopharynx was related to apnea index.
