Abstract
Purpose: To explore the role of magnetic resonance imaging (MRI) in the evaluation of patients with velopharynageal insufficiency (VPI) and to use the MRI information obtained to aid in the treatment decision besides its role in the postoperative evaluation of the patients after VPI correction.
Materials & Methods: This interventional study was carried out on 8 patients with VPI due to decreased velar mobility. Preoperative clinical, nasopharyngoscopy and MRI were done for all patients. All patients were undergone intravelar veloplasty to reposition the muscles in their normal position and increase velar mobility. All patients underwent regular follow up for three months by clinical, nasopharyngoscopy and MRI.
Results: MR images provided evidence of an interruption of levator veli palatine muscle tissue in the midline and a substantial attachment of levator muscle tissue to the posterior border velopharyngeal insufficiency of the hard palate preoperatively which was coincident with the decreased velar mobility via nasopharyngoscopy in all patients. Postoperatively, velar mobility was increased in all patients which was evident by nasopharyngoscopy and quantitative analysis of LVP by MRI.
Conclusion: MRI has important role in the diagnosis of VPI which was confirmed by nasopharyngoscopy besides its role in the postoperative evaluation of the LVP.
Key Words: magnetic resonance imaging (MRI), levator veli palatine muscle (LVP), and velopharyngeal insufficiency (VPI).
