鼻咽腔閉鎖機能計測用マスクについての検討

Masks used in a hydrodynamic examination for determining closure function of the velopharynx were compared with respect to the mechanism of blocking and preventing air expiration, and reproducibility and reliability of measured values. Three types of masks were used for measurement ; a ready-made mask for flow nasality (R Co.), a double-mask type, and a nasalcannula type used in our department. With the ready-made mask, the air expired from the oral cavity flowed into the mask for subsequent nasal inhalation because the ready-made mask incorporates a smaller mask for nasal use within the large-size mask. A flow nasality graph is thus considered useful for rough evaluation, but it seemed necessary to reconsider reproducibility and reliability of measured values for diagnosis, treatment and investigation of the closure function of the veropharynx. All three types of masks require modification before they can be routinely applied to young patients.
