Objective:
To study the treatment outcome of laryngeal function sparing of pharyngectomy in pyriform sinus carcinoma.
Method:
Fourty-two cases with pyriform sinus cancer in laryngeal function sparing surgery were collected from 1989 to 1999. The method of operation, the complication and surviving rate were analyzed.
Result:
The decannulation rate was 61.9% (26/42) . The rate of complication was 31.0% (13/42), the 3 years and 5 years' survival rates were 76.1% and 66.6% respectively.
Conclusion:
Laryngeal function preserving surgery in pyriform sinus cancer could performed for stage T1, T2 and part of stage II, IV patients, and this surgery can improve the patients, life quality.

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,...
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,...
