[The value of laryngoscopy and MRI in diagnosis and management of pharyngolaryngeal venous malformations].

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.
