Hypopharyngeal carcinoma is an aggressive malignancy that usually presents at a late stage, thereby resulting in an overall poor prognosis fir these unfortunate patients. The most effective treatment of pyriform sinus carcinoma combines surgery and radiation. Total laryngopharyngectomy is necessary in advanced tumors, but may not be appropriate in limited lesions. Therefore several procedure for partial laryngopharyngectomy have been proposed. Supracricoid hemilaryngopharyngectomy is the one of these procedure. This report presents one case of supracricoid hemilaryngopharyngectomy in a patient with pyriform sinus medial wall cancer and analyses aerodynamic study before and after operation.

Pharyngocutaneous fistula is one of the most common wound complications after total laryngectomy. The leakage of saliva may cause an erosion of greater vessels nearby and result in a life-threatening bleeding. 65-year-old male received laryngectomy and pharyngectomy followed by Latissimus dorsi flap reconstruction due to recurred laryngeal cancer with oropharyngeal extension after postoperative radiotherapy. Pharyngeal fistula was developed and an excessive fresh blood flowed through the oral and nasal cavity. The patient was transferred to the operating room immediately, and the causing artery was ligated. The rupture of the common carotid artery and its branches should be warned when the pharyngocutaneous fistula is developed. Prompt and proper therapy must be performed for the patients with impending or acute hemorrhage.

Purpose: Various attempts of reconstruction for pharyngoesophageal defects after ablative surgery have been made to restore the function of the pharyngoesophagus. A fabricated tubed radial forearm free flap or free jejunal free flap was used when the width of remnant pharyngeal wall was less than 50% of the normal width. However there are many disadvantages such as stricture, saliva leakage and fistula formation on tubed radial forearm free flap. The jejunal free flap has the problem such as short pedicle, poor tolerance of ischemic time, wet voice and delayed transit of swallowed food due to the uncoordinated contraction. The authors studied the utility of patch-type radial forearm free flap using the remnant posterior pharyngeal wall of the hypopharynx. Methods: Retrospective reviews in Severance Hospital were made on 25 patients who underwent reconstruction surgery with patched radial forearm free flap because of the hypopharyngeal cancer between 1996 and 2005. The patients of Group I had the narrow posterior pharyngeal wall and its width was less than 3centimeters after the tumor was resected. Those of Group II had the partial pharyngectomy and the width of the remnant pharynx was larger than 3 centimeters. Results: Seven patients belonged to the group I and the flap of this group had 100% survival rate. One case of fistula and no swallowing discomfort due to stricture was reported. The Group II including 18 patients also had the 100% flap survival rate. Neither fistula nor stricture was seen but the lower diet grade was checked. Conclusion: The patch type radial forearm free flap using the remnant pharyngeal wall have the advantage of the radial forearm free flap, and furthermore this flap is the safe reconstructive method even if the width of the remnant pharyngeal wall is less than 30% of that of normal pharynx.

Purpose: This study was carried out to confirm clinical values and limitations of postoperative radiotherapy for hypopharyngeal carcinoma, to evaluate various prognostic factors which may affect to the treatment results and to use these results as fundamental data for making a new treatment strategy. Methods and Materials:. A retrospective analysis was peformed on 64 previously untreated patients with squamous cell carcinoma of the hypopharynx, seen between 1988 and 1999 at Pusan National University Hospital. Most of patients were treated by laryngopharyngectomy and neck dissection followed by conventional fractionated postoperative radiotherapy on surgical bed and cervical nodal areas. Results: The five-year overall survival rate and cause-specific survival rate were 42.2 percent and 51.6 percent, respectively. Univariate analysis of various clinical and pathologic factors confirmed the overall stage, TN-stage, secondary primary cancers, surgical positive margin, nodal extracapsular extension, total radiation doses as significant prognostic factors of hypopharyngeal carcinomas. But in multivariate analysis, TN-stage, surgical positive margin and extracapsular extesion were only statistically significant. Conclusion: In resectable cases of hypopharyngeal carcinoma, combined surgery and postoperative radio-therapy obtained good treatement results, even though sacrificing the function of larynx and pharynx. But in advanced and unresectable cases, with respect to survivals and qualify of life issues, we were able to confirm some limitations of combined therapy. So we recommend that comparative studies of recent various chemo-radiotherapy methods and advanced radiotherapy techniques with these data should be needed.
