Objective:
To explore the feasibility of laryngeal function preservation in surgical treatment of hypopharyngeal carcinoma with restrained vocal cord motility.
Methods:
Twenty-six cases of hypopharyngeal carcinoma treated with conservative hypopharyngectomy were retrospectively analyzed. Partial resection of pyriform sinus and partial laryngectomy were performed. Suturing the remaining hypopharyngeal mucosa was used to cove the wound of hypopharynx in 5 cases, epiglottis complex flap in 21 cases. All patients received postoperative radiotherapy.
Results:
The overall 3- and 5-year survival rates were 61.4% and 50.8% respectively. 76.9% (20/26) patients have laryngeal functions (voice, respiration and deglutition) completely restored and 23.1% (6/26) partially restored (voice and deglutition).
Conclusions:
To improve the quality of life of the cases, the preservative surgery is feasible for the selected hypopharyngeal carcinoma cases with restrained vocal cord motility.

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...

Nasopharynx
The nasopharynx, bordered by the conchae of the nasal cavity, serves exclusively as an air conduit. In its superior region, the pharyngeal tonsils or adenoids are located. These tonsils are clusters of lymphoid reticular tissue akin to a lymph node. The precise...
