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.
Method: Fifty-six patients were implanted with Groningen voice prostheses to rebuild voice after total laryngectomy. The clinical data were analyzed retrospectively.
Result: 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%.
Conclusion: The combination of pharynx plexus nerves resection and cricopharyngeal myotomy can make higher success rate of voice restoration.
