APREVENT MEDICAL INC. | Customized Laryngeal Implant


Vocal fold paralysis is the most common neuromuscular disorder in the larynx. It is a condition caused by impairment of the recurrent laryngeal nerve or high vagal lesions, resulting in immobility of one or both vocal folds. Etiologies are mostly iatrogenic, after thyroid, neck, chest or skull base surgery. Other causes include neurogenic disorders such as stroke or Parkinson’s disease, aging, head and neck tumor radiation, infection, and in some cases they are idiopathic.

Medialization thyroplasty Type I (MT) is the gold standard treatment for glottis insufficiency, by inserting alloplastic or autologous materials into the paraglottic space to achieve glottis closure. In patients with a large glottis gap or high vagal lesions, arytenoid adduction (AA) can be performed to reduce the posterior glottis gap and correct the vertical height difference between the vocal folds. Currently, several products are available in the market, including silastic implants, Gore-Tex stripes, or titanium plates. Unlike existing products, APrevent’s thryoplasty implant combines the advantage of both MT and AA for optimized results. It can also be adjusted intra- and postoperatively. APrevent’s product is designed to fit individual needs and greatly improves the quality of life.
