  • Title: Preservation of laryngeal function after removal of carcinoma of the pyriform sinus.
    Author: Wang TD.
    Journal: Chin Med J (Engl); 1989 Nov; 102(11):825-30. PubMed ID: 2517722.
    Abstract:
    Since March 1978, conservative laryngopharyngeal surgery has been used in the treatment of carcinoma of the pyriform sinus at this hospital. For pharyngeal reconstruction, cervical skin flap, deltopectoral flap, free microvascular bowel transfer, and pectoralis major myocutaneous flap and gastric pull-up transfer were used. The remaining part of the larynx was repaired with cervical skin flap, sternohyoid myofascia, epiglottis or remnant of epiglottis for complete rehabilitation (phonation, deglutition protection and respiration) or partial rehabilitation (phonation and deglutition protection) of laryngeal functions. 47 patients with carcinoma of the pyriform sinus were treated, and fairly good results were obtained. The 5-year survival rate was 41.7%, and the 3-year survival rate 50%. The laryngeal function restored completely in 31 patients and partially in 16. It is suggested that preservation of the unaffected part of the larynx is feasible both for eradication of tumor and preservation of laryngeal function.
