[Clinical significance of reducing cricopharyngeal dysfunction on voice restoration].
OBJECTIVE
To discuss the effect of reducing the cricopharyngeal dysfunction on the Groningen prosthesis voice restoration following total laryngectomy and the effect of different methods.


METHODS
Fifty-six patients were implanted with Groningen voice prostheses to rebuild voice after total laryngectomy. The clinical data were analyzed retrospectively.


RESULTS
Of 56 patients, 412 patients successes in voice restoration. The success rate of amputating pharynx plexus nerves group was 60.0%, amputating cricopharyngeal muscle group was 62.5%, and the amputating pharynx plexus nerves and cricopharyngeal muscle group was 96.0%.
