目的：通过MRI获得腭裂修复患者腭提肌的详细解剖和生理信息，并与Ettema等人（2002）报道的正常人的结果进行比较。设计：前瞻性研究。单位：大学附属医院。参与者：4名男性，年龄22 - 43岁，唇腭裂修复。主要观察指标：从静止位置和动态语音磁共振图像中获得提肛面纱肌的四项定量测量：肌肉原点之间的距离、肌肉原点角度、肌肉长度和肌肉厚度。结果：提肛面纱肌的长度和厚度在受试者中有所不同，与以往研究中正常受试者的测量结果不同。提肛面纱肌原点之间的距离、长度和厚度均小于正常人。提肛面纱肌有系统的变化，取决于元音和辅音类型。提肛面纱肌的起始角和长度从休息、鼻辅音、低元音、高元音和摩擦辅音逐渐变小。这些变化与正常受试者一致。结论：本研究有助于更好地了解腭裂解剖与正常解剖的提肛面纱肌。MRI的应用有望成为先天性腭裂患者诊断和最终辅助治疗的重要工具。
Objective: To obtain detailed anatomic and physiologic information on the levator veil palatini muscle from MRI in individuals with repaired cleft palate and to compare the results with those from normal subjects reported by Ettema et al. (2002).Design: Prospective study.Setting: University-based hospital.Participants: Four men (ages 22 to 43 years) with repaired cleft lip and palate.Main Outcome Measures: Four quantitative measurements of the levator veil palatini muscle from rest position and dynamic speech magnetic resonance images were obtained: the distance between the origins of the muscle, angle of origin of the muscle, muscle length, and muscle thickness.Results: The length and thickness of the levator veil palatini muscle varied among the subjects and were different from measurements obtained from normal subjects in a previous study. The distance between origin points, length, and thickness of the levator veil palatini muscle were smaller than those of the normal subjects. There were systematic changes of the levator veil palatini muscle, depending upon vowel and consonant types. Levator veil palatini muscle angle of origin and length became progressively smaller from rest, nasal consonants, low vowels, high vowels, and fricative consonants. These changes are consistent with those of the normal subjects.Conclusions: This study contributes to a better understanding of cleft palate anatomy in comparison with normal anatomy of the levator veil palatini muscle. The use of MRI shows promise as an important tool in the diagnosis and eventual aid to treatment decisions for individuals born with cleft palate.
