The value of laryngoscopy and MRI in diagnosis and management of pharyngolaryngeal venous malformations
-
摘要: 目的:探索电子喉镜及MRI检查在咽喉部静脉畸形(VMs)诊治中的应用,为临床治疗提供参考。方法:回顾性分析73例咽喉部VMs患者的临床资料。全部患者治疗前进行电子喉镜检查及MRI检查,统计累及的咽喉部解剖亚区。通过Mimics 20.0软件选取MRI感兴趣区域(region of interest,RoI)的阈值范围,计算肿瘤体积。结果:电子喉镜与MRI对咽喉部VMs的检出率无显著差异(P>0.05)。咽喉部VMs最常见的侵犯部位为舌根(37.0%),其次为会厌(35.6%)及梨状窝(32.9%)。咽喉VMs体积为0.75~76.33 cm3,平均(17.43±6.28) cm3。结论:电子喉镜与MRI在诊断咽喉部VMs时各具优势,应当互补、结合应用,以获得足够的信息,制定合理的治疗方案。在诊治面颈部VMs时,建议常规行电子喉镜检查进行筛查,评估咽喉受累情况。Abstract: Objective: To investigate the value of laryngoscopy and MRI in diagnosis and management of pharyngolaryngeal venous malformations(VMs), and to provide reliable evidences for clinical application. Method: The clinical data of 73 patients with pharyngolaryngeal VMs was analyzed retrospectively. Laryngoscopy and MRI were detected before treatment. The involved anatomic sites and the volume of VMs were calculated by Mimics version 20.0. Result: No significant difference was found in the detection rate of VMs between laryngoscopy and MRI(P>0.05). The most common sites involved in pharyngolaryngeal VMs were the tongue base(37.0%), followed by epiglottis(35.6%) and pyriform sinus(32.9%). The volume of pharyngolaryngeal VMs ranged from 0.75 cm3to 76.33 cm3, with an average volume of(17.43±6.28) cm3.Conclusion: Laryngoscopy and MRI have their own advantages in diagnosing of pharyngolaryngeal VMs. Thus a combination which provides more information to formulate reasonable treatment plan has great diagnosing value. When treating with facial and cervical VMs, routine laryngoscopy is recommended to screen and to evaluate the laryngopharyngeal involvement.
