*6.2.6 Posterior cricoid split and grafting*

This surgery aims at widening the glottic aperture by expanding the posterior laryngeal commissure with the help of costal cartilage. It can be performed via both open and endoscopic approach. The advantage of this procedure is that integrity of the vocal folds and arytenoids is kept intact and there are also minimal chances of aspiration.

### *6.2.7 Reinnervation*

Reinnervation using ansa cervicalis nerve-muscle pedicle transfer or phrenic nerve transfer to posterior cricoarytenoid muscle can be done. The results are, however, not consistent and more clinical human trails are further needed to draw a definite conclusion.
