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.

Larynx
Anatomy of the Larynx
The larynx consists of various components, including cartilage, muscles, and vocal cords. Its structure includes three large unpaired cartilages—the thyroid, cricoid, and epiglottis—and three smaller paired cartilages—the arytenoids, corniculates, and...
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...
