The contractile function of the posteroir cricoarytenoid muscle was investisated after reinnervated from the phrenic nerve. The data showed that the posteroir cricoarytenoid muscles reinnervated from the phrenic nerve repined contraction very well. As to the contractile properties, it had no difference in the contractile tension and the time of contraction of the posteroir cricoarytenoid muscles on the reinnervated side and on the normal side. The results demonstrate that the method to reinnervate the posteroir cricoarytenoid muscle by the phrenic nerve in order to restore muscle function was possible.
