Bilateral Vocal Fold Paralysis Clinical Trial
Official title:
Selective Bilateral Laryngeal Reinnervation as a Secondary Treatment in Case of Bilateral Vocal Fold Paralysis: Analysis of Phonatory and Ventilatory Results
Selective laryngeal bilateral reinnervation as a secondary treatment in patients with
bilateral vocal fold paralysis, previously treated by endoscopy, without residual arytenoids
ankylosis.
The surgical procedure is : functional reinnervation with the upper root of one phrenic
nerve, is used for reinnervation of both cricoarytenoid muscles (laryngeal inspiratory
muscles), and simultaneous reinnervation of adductor laryngeal muscles is performed by right
and left thyro -hyoid nerves (coming from the hypoglossi) on both sides.
Results are obtained after 6 to 9 months delay. In case of good inspiratory arytenoid
abduction, and residual dysphonia, a secondary vocal fold medialization is done by an
endoscopic approach 12 months after reinnervation (included in the protocol).
Improvement is expected in voice and breathing, without aspiration.
