[Laryngeal function preserving surgery in hypopharyngeal carcinoma]
Objective:
To investigate the results of the conservation laryngectomy in patients with hypopharyngeal carcinoma.
Methods:
Twenty-three cases with hypopharyngeal carcinoma that were treated with function-sparing laryngectomy during a 15-year period were reviewed retrospectively.
Results:
The 3-year survival rate was 73.9% (17/23) and 5-year survival rate was 47.8% (11/23). Severe complication occurred in 8 of 23 (34.8%). Complete restoration of laryngeal function was achieved in 20 cases (87%) and deglutition restored in all patients (100%). The mean duration of oral intake was 11.8 days (6-33 days) and mean hospitalization was 32 days (14-94 days).
Conclusion:
Conservation laryngectomy and hypopharyngectomy is not only efficacious in the treatment of hypopharyngeal carcinomas, but also reserves laryngeal function and thus improves the quality of patients life.

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,...
