Patients with palatine fissure have inadequate velopharyngeal closure (VPC), with consequent vocal hypernasality which can be reduced by a basal tone.
To compare VPC during a basal tone with the emission of a modal recording, in patients with repaired post-foramen palatine fissure.
Case study with four adult men, all with repaired post-foramen palatine fissure. VPC images through nasal-pharyngoscopy during the emission o f the [a] vowel in a modal and basal recording. The images were studied by four ENTs.
In three subjects there was no change in the type of VPC considering the recordings analyzed; the changes which happened to most of the subjects are associated only to the degree of movement of the structures involved, since in the basal recording the movement of the laryngeal lateral walls was kept, the movement of the posterior pharyngeal wall stabilized, the movement of the palatine veil was mildly reduced, and the Passavant fold was evident.
The type of VPC was kept in the four subjects analyzed, when we compared the modal and basal recordings, there was a modification in the degree of movements in the structures involved, making it clear the Passavant Fold.
比较腭裂患者修复后的腭咽闭合功能在基频音与嗓音段发音时的差异。
对 4 例男性腭裂患者分别进行嗓音段[a]音和基频音发音时的鼻咽喉镜检查,对 2 种发音时的腭咽闭合图像由 4 位耳鼻喉科医师进行分析。
3 例患者在 2 种发音时的腭咽闭合类型无变化,腭咽闭合运动的变化主要体现在运动幅度的改变,即基频音时,喉外侧壁运动保持,后咽壁运动稳定,软腭运动轻度减小,会厌皱襞明显。
4 例患者的腭咽闭合类型在 2 种发音时无变化,但参与腭咽闭合的结构运动幅度发生了改变,会厌皱襞明显。
