There are many approaches in surgery of posterior hypopharyngeal wall cancer according to location, extent, and invasion depth of primary cancer. And many reconstruction methods have been used in reconstruction of surgical defect remaining after wide resection of primary cancer. Posterior hypopharyngeal wall cancer is relatively rare, so its surgical experiences are fewer than those of pyriform sinus cancer and there have been few reports of surgical approaches and reconstruction methods of posterior hypopharyngeal wall cancer. Recently, we experienced a case of posterior hypopharyngeal wall cancer reconstructed with longus colli flap and skin graft after failure of radial forearm free flap in a 72-year -old man and report it with the review of the literatures.

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.

Reconstruction for hypopharynx and cervical esophagus after wide resection of extensive hypopharynx and larynx cancers have been used various methods including myocutaneous flaps, gastric pull up, md jejunal or large bowel free graft. Recently, the authors had experienced hypopharynx and larynx cancers with extension to the posterior hypopharyngeal wall and thoracic esophagus. Of course, these reconstructive methods should be selected in accordance with the patient's age, physical status, extend of prim.:W lesion, and defect after on block resection, however, gastric pull up was performed in hypopharynx cancer which had skipped lesion in the thoracic esophagus and jejunal free grafts were performed in case 2, 3 which had a extended lesions to the posterior pharyngeal wall. Some complications were noted, which were successfully stabilized by conservative managements. The gastric pull up and jejunal free graft were considered suitable methods for reconstrunction of hypopharynx and cervical esophagus, however, further studies are necessary about it.

Background: Hypopharyngeal cancer represents about one-third the incidence of laryngeal cancer which is the most common cancer in head and neck area. Although there have been numerous reports regarding its clinical and statistical characteristics, more precise and ample data should be collected and analyzed in this country. Objectives: This study was designed to evaluate the pattern and patient's profile of the hypopharyngeal cancer, and we reviewed the treatment outcomes to search for an index of treatment modalities. Materials and Methods: The authors retrospectively analyzed 73 cases of hypopharyngeal cancer treated at Yonsei Medical Center during the 10-year period from 1985 to 1994. Five-year survival rate was calculated according to the primary site, clinical stage and treatment modality. Results: The incidence was predominated in male by 9 to 1 and peak incidence was 6th and 7th decades. Pyriform sinus was the main primary site(80.8%) followed by posterior hypopharyngeal wall(13.7%) and postcricoid area(5.5%). Advanced stage cancers(87.7%) were more common than early stage cancers. Radiotherapy(60.3%) was the most commonly used as primary treatment modality. Neck node metastasis was early occurred even in early stage cancers(61.5%), and overall rate of neck node metastasis was 69.9%. All surgical cases received procedures more than total laryngectomy and partial pharyngectomy. The most common cause of death was primary failure(81.5%) and it was highest in radiotherapy group. Five-year survival rate was significantly high in surgery group(90.9%). The overall 5-year survival rate of hypopharyngeal cancer was 30.3%. Conclusion: High index of suspicion should be required for early diagnosis. Also, surgery may be recommended for the primary treatment modality in advanced stage cancers.

A rerospective review of fifty patients with carcinoma of hypopharynx treated with $RT{\pm}surgery$ was studied for eleven-year period from 1974 to 1984. Of the 50 patients,46 were pyriform sinus in origin, 4 were posterior pharyngeal wall. Eighty-eight percent of patients were locoregionally advanced(stage III, IV) and 78% of patients presented conical lymphadenopathy. 5-year disease-free survival rate of the pyriform sinus ca. was $25.4\%$ in RT alone group, $80\%$ in combined modality group and $30.6\%$ in overall. Local control rate with RT alone in early stage (II) was excellent $(100\%)$, however combined modality appears to be better for local control$(80\%)$ in advanced stage (III, IV) as compared with that of RT alone group $(32\%).$ On basis of this study, RT alone is effective in terms of local control and functional preservation in treatment of early stage of pyriform sinus ca. while surgery can be reserved for salvage purpose when RT fails and combined modality is recommended in patients with locally advanced stage for better local control and survival.
