Standard approaches to arytenoid adduction and abduction 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 abduction or adduction) requires:
- 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-gauge trocar through the cricothyroid membrane into the paraglottic space to engage the muscular process of the arytenoid
Additional Benefits of the ARD:
- 'Minimal Access Surgery'
- Reversible
- Permits 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
