The results of treatment according to surgical procedures in 68 patients with squamous cell carcinoma of the hypopharynx and incidence of double cancer with esopahgeal cancer were analyzed. Surgical procedures for cancer resection were partial pharyngectomy with total laryngectomy (TLP) in 16 patients, total pharyngolaryngocervical esophagectomy (TPLCe) in 18 and total pharyngolaryngoesophagectomy (TPLE) in 33, respectively. Procedures of esophageal reconstruction for patients who had TPLE were gastric pull-up in 3lpatients and pedicled colon in 2 and that for patients who had TPLCe were deltopectoral flap in 3, free tissue tranfer with microsurgical vessel anastomosis in 15 (jejunum in 14, forearm flap in 1). The 5-year survival rate of all patients was 47%. There was no significant differece in survival rate between those patients with TPLE and those with TPLCe or TLP. Among them, intra-thoratic esophageal cancer was detected in 4 patients (6%) and the incidence of skip lesion in cervical esophagus was estimated to be 3-9% (2-6patients). First choice of surgical procedures for hypopharyngeal cancer should be TPLCe, but TPLE would be indicated for about 15% of these patients.
