[A comparative study of different neuromuscular pedicle embedded in posterior cricoarytenoid muscle].

OBJECTIVE

To compare the results and effect of different neuromuscular pedicle (NMP) embedded in posterior cricoarytenoid muscle.

METHOD: In 22 dogs, combined vocal cord paralysis models were made. The first group (10 dogs) were embedded by sternohyoid muscle pedicle of ansa cervicalis, the second (10 dogs), accessory sternocleidomastoid neuromuscular pedicle, the third (2 dogs), control group.

RESULT: Evaluation was possible in 19 dogs. Reinnervation of the left posterior cricoarytenoid muscle occurred in 17 dogs following NMP. Return of spontaneous abduction in the operated side with NMP was noted after 4 months postoperatively. There was little difference between the two NMP groups.

CONCLUSION

NMP was successful to reinnervate the posterior cricoarytenoid muscle.
