摘要
目的探讨腭咽磁共振成像对腭咽闭合不全诊断及术前评估的可行性及准确性。方法2002年以来，通过对6例腭裂术后腭咽闭合不全患者进行正中矢状面、横断面和冠状面扫描。并与头颅侧位X线片及颅底位片对照，通过手术直视测量证实。结果腭裂术后腭咽闭合不全患者磁共振成像主要表现为咽腔深、软腭短、咽后壁及侧壁运动障碍等，可精确定量，结果准确，可重复性好，与临床表现及术中探察一致。结论磁共振成像易操作、无创且可精确定量、可重复，可对腭咽闭合不全患者进行有效的术前评估，对其诊断及手术方案的选择有重要指导作用。
Objective To assess the feasibility and actuality of MR imaging on diagnosis and evaluation of velopharyngeal insufficiency preoperatively. Methods Since 2002, six patients with velopharyngeal insufficiency were examined with MRI using midsagittal, coronal, and axial images, contrast with radiography, to affirm configuration and movements of soft palate, posterior and lateral pharyngeal walls, and velopharyngeal opening for the choices of following surgeries. Results MRI visualizes directly and measures objectively the shorter soft palate, confined movements of soft palate, lateral or/and posterior pharyngeal wall, and deeper and enlarged velopharyngeal opening, which were coincided with clinical symptoms and affirmed by observations in the following operations, surpassing radiography. Conclusions MRI is effective, actual, and uninvasive in imaging and measuring the velopharyngeal insufficiency, thus has a potential role in investigation and planning surgical repairs.
