ARD- Arytenoid Repositioning Device

 

 


Standard approaches to arytenoid ad- and ab-duction require

  • Neck incision
  • Transection of muscles
  • Removal of cartilage
  • Mobilization of the pyriform sinus
  • Dissection close to the carotid artery to place a suture in the muscular process of the arytenoid

    Placement of ARD (for ab- or ad-duction)
  • Small anterior neck incision
  • No transection of muscles
  • No removal of cartilage
  • No mobilization of the pyriform sinus
  • No dissection close to the carotid artery
    to place the device employing an 18 guage trocar
    through the cricothyroid membrane into the paraglottic
    space to engage the muscular process of the arytenoid

     
    ARD -
  • 'Minimal Access Surgery'
  • Reversible
  • Prmits positioning of arytenoid with greater precision than a suture

Adduction:

  • Unilateral laryngeal paralysis
  • Arytenoid subluxation/dislocation repositioning

Abduction:

  • Bilateral laryngeal paralysis
  • Acute placement (at time of thyroidectomy) chronic
  • Posterior glottic scarring - ancillary measure to grafting
