Voice preservation in pyriform sinus carcinoma by hemicricolaryngopharyngectomy. 1984

Y P Krespi, and G A Sisson

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.

D010614	Pharynx	A funnel-shaped fibromuscular tube that conducts food to the ESOPHAGUS, and air to the LARYNX and LUNGS. It is located posterior to the NASAL CAVITY; ORAL CAVITY; and LARYNX, and extends from the SKULL BASE to the inferior border of the CRICOID CARTILAGE anteriorly and to the inferior border of the C6 vertebra posteriorly. It is divided into the NASOPHARYNX; OROPHARYNX; and HYPOPHARYNX (laryngopharynx).	Throat,Pharynxs,Throats

D013524	Surgical Flaps	Tongues of skin and subcutaneous tissue, sometimes including muscle, cut away from the underlying parts but often still attached at one end. They retain their own microvasculature which is also transferred to the new site. They are often used in plastic surgery for filling a defect in a neighboring region.

D013957	Thyroid Cartilage	The largest cartilage of the larynx consisting of two laminae fusing anteriorly at an acute angle in the midline of the neck. The point of fusion forms a subcutaneous projection known as the Adam's apple.	Cartilage, Thyroid,Cartilages, Thyroid,Thyroid Cartilages
D014831	Voice	The sounds produced by humans by the passage of air through the LARYNX and over the VOCAL CORDS, and then modified by the resonance organs, the NASOPHARYNX, and the MOUTH.	Voices
D037981	Neck Dissection	Dissection in the neck to remove all disease tissues including cervical LYMPH NODES and to leave an adequate margin of normal tissue. This type of surgery is usually used in tumors or cervical metastases in the head and neck. The prototype of neck dissection is the radical neck dissection described by Crile in 1906.
