Swallowing and pharyngeal function in postoperative pharyngeal cancer patients.

This study examines the pharyngeal phase of swallowing after the resection of pharyngeal cancer, and focuses on the pharynx as a functional organ. The purpose of the study was to obtain information on both reconstruction and rehabilitation in cases of surgically treated pharyngeal cancer. The records of 21 consecutive patients who underwent surgical treatment of oropharyngeal and hypopharyngeal squamous cell carcinoma between 1990 and 1993 were reviewed. Functional results following surgery were graded on a numerical scale in three categories: pharyngeal swallow, laryngeal and lower airway protection, and oral alimentation. Three treatment groups were observed: group 1 = transoral excision with primary closure (six patients); group 2 = composite resection with primary closure (nine patients); and group 3 = composite resection with deltopectoral or pectoralis major flap closure (six patients). Comparison of pharyngeal swallow and laryngeal protection functions showed no significant difference between the three groups. However, oral alimentation performance in group 1 was significantly better than in group 3, and groups 1 and 2 achieved a similar level. In patients with T3 and T4 tumors postoperative function was poor and no difference in postoperative function was demonstrated between patients undergoing reconstruction with primary closure and patients undergoing reconstruction with deltopectoral or pectoralis major flaps. Patients with T3 and T4 tumors experienced impaired postoperative function regardless of the method of reconstruction used. This is not a condemnation of the surgical treatment of advanced pharyngeal tumors, but rather a suggestion that other reconstruction techniques be considered.
