Voice preservation in pyriform sinus carcinoma by hemicricolaryngopharyngectomy
Abstract:
Hemicricolaryngopharyngectomy was performed for anterior pyriform sinus carcinomas with preservation of voice and swallowing. The surgical specimen includes the homolateral half of the hypopharynx, larynx, and cricoid ring. The pharynx is reconstructed with a pectoralis myocutaneous flap, a deltopectoral flap, skin or dermal graft. A semirigid mucosa-lined speech tube is created by folding in the remaining half of the larynx. This tube, which is 4 to 5 mm in diameter, serves as a phonatory structure. Speech is produced by occluding the stoma with the finger and shunting air via this dynamic pseudolarynx. Patients maintain a permanent tracheostomy. Our experience includes 14 cases with up to 4-year follow-up.

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,...
