Abstract:
Objective To investigate the functional changes of anastomosed vascular or neurovascular mini-muscle transfer and to provide experimental data to clinical application. Methods 32 New Zealand rabbits were operated on by anastomosed neurovascular mini-muscle transfer. In group A, 16 rabbits accepted the anastomosed vascular mini-muscle transfer. In group B, 16 rabbits accepted the anastomosed neurovascular mini-muscle transfer. The electromyography was measured 2 months and 3 months after operation. Results The amplitude of electrical muscle graph (EMG) data in the group A was (2.02±0.41)mV 2 months after operation, and (1.73±0.18) mV 3 months after operation. The EMG data in the group B was (3.90±0.52) mV 2 months after operation and (3.35±0.86) mV 3months after opera-tion. The difference between the two groups was significant (P<0.01). The EMG of anastomosed neu-rovasular mini-muscle transfer was significantly greater than that of anastomosed vasular transfer only.There was no significant difference in latent period of EMG between the two groups (P>0.05). Conclu-sions The muscle functional recovery of anastomosed neurovascular mini-muscle transfer is significant with less demage and no secondary deformity. The results suggest that this technique is worthy to apply for treating facial paralysis.
