A rare case of acute descending necrotizing mediastinitis(DNM) secondary to spontaneous rupture of hypopharynx is reported. Due to the right lower cervical abscess the patient had undertaken limited right anterior cervical drainage at other department. After transferring to our department he undertook combined wide cervical mediastinal drainage and mediastinal drainage via right thoracotomy. However mediastinal drainage was ineffective. So the second operation was performed and chest tubes were relocated. He had an uneventful postoperative course. As far as the cause of acute descending necrotizing mediastinitis was concerned, we couldn't find any literature in Korean or English except one case that dealt with spontaneous rupture of the hypopharynx.

Despite of technical advances in surgery & other therapeutic modalities five-year survival rates in patients with carcinoma of hypopharynx have remained low. Many techniques have been used to create a structure capable of allowing the passage of food and fluids in an attempt to maintain the anatomy and physiology of the upper digestive system. The development of microsurgical techniques and the concept of mucocutaneous unit has brought about important changes in the reconstruction of cervical esophagus following tumor resection. The one-stage procedure using microvascular anastomosis of free jejunal graft provides physiologic reconstruction of cervical esophagus and has a low morbidity rate as well as a short recuperation time. With free jejunal graft, there is marked improvement in the quality of life and numerous advantages over the previous methods of reconstruction. Reconstruction of esophageal defect after resection of carcinomas of the hypopharynx, and cervical esophagus has traditionally been carried out with deltopectoral, or musculocutaneous skin-lined flaps. A second approach is to reconstruct the defect with the colon or stomach. A more ideal mettled is to repair these defects with mucosa-lined flaps. The authors experienced 35 cases of reconstruction of cervical esophagus after resection of carcinoma of the hypopharynx with free jejunal autograft and one case of secondary repair with radial forearm free flap after failure of initial free Jejunal autograft. Postoperative results were satisfactory in most patients and two patients expired in 8 days postoperatively because of carotid blow out by chronic inflammation.

We have recently experienced three interesting foreign bodies in the air way. Case 1. A spring coil of ball pen which was rusty and divided into two for one year was in the right inferior lobar bronchus of a 10 year old boy. Case 2. A bean lodged on the orifice of the right upper lobar bronchus and right middle lobar bronchus, resulted in complete atelectasis of the right upper and middle lobes of a 6 month old girl. Cases 3. A wire used in fixing a pair of socks was hanged transeversely for one month between epiglottis and hypopharynx of a 11 month old boy.

Two cases of severe caustic injury of the hypopharynx, esophagus, and stomach are presented. Restoration of digestive continuity was accomplished by retrosternal isoperistaltic interposition of the transverse and left colon on the post-injury 73rd and 66th day respectively. The upper oro-colon continuity was made by a cervical approach, a vertical incision at the posterior hypopharyngeal wall, and interrupted one-layer sutures using 3-0 Dacron suture materials. The distal continuity was made by colojejunostomy between the transposed colon and proximal jejunum. There was no event after the operation in both cases. The posterior vertical hypopharyngotomy and hypopharyngocolostomy at the early post-injury period may be the preferred procedure to obtain normal deglutition in patients with esophageal stricture associated with hypopharyngeal injury.

Fibromatosis is a broad group of benign fibroblastic proliferation that shows locally aggressive growth but never metastasize. Common anatomic sites include abdominal wall, extremity, and mesentery. Little is reported about clinical features and outcome of fibromatosis of the head and neck. The treatment of choice is wide excision, which is often difficult. Postoperative recurrence rates are high. We recently confirmed a unique case of fibromatosis occurred on the hypopharynx of 44-year-old male patient and report this interesting case with review of literature.

Background: The posterior movement of mandible was known as the main cause of the changes in the pharyngeal airway space (PAS) and the postoperative obstructive sleep apnea (OSA). The purpose of this study was to know the changes of PAS and position of hyoid bone. Methods: Lateral cephalographies of 13 patients who had undergone sagittal split ramus osteotomy (SSRO) setback surgery were taken preoperatively (T1), postoperatively within 2 months (T2), and follow-up after 6 months or more (T3). On the basis of F-H plane, diameters of nasopharynx, oropharynx, and hypopharynx were measured. The movements of the soft palate, tongue, and hyoid bone were also measured. Results: The amount of mandible setback was $7.5{\pm}3.8mm$. In the measurements of PAS, there was a statistically significant decrease of $2.8{\pm}2.5mm$ in nasopharynx (P < 0.01), and $1.7{\pm}2.4mm$ in oropharynx (P < 0.01) were observed after surgery. The hypopharynx decreased $1.0{\pm}2.1mm$ after surgery and continuously decreased $1.0{\pm}2.8mm$ at follow-up. The changes in hyoid bone position showed the posterior movement only after surgery and posteroinferior movement at follow-up. Conclusions: The PAS such as nasopharynx, oropharynx, and hypopharynx showed relatively high correlation with the amount of mandibular setback. The change of resistance in upper airway may be important for the prevention of OSA after mandibular setback surgery.

Background and Objectives: Multiple primary tumors of the upper aerodigestive tract are not unusual. We examined head and neck cancer patients to discover the presence of second primary cancer in their upper gastrointestinal tract, using esophagogastroscopy. Materials and Methods: Endoscopic examination of the upper gastrointestinal tract was performed on 51 patients whose head and neck cancers were treated at department of therapeutic radiology from August 1996 to April 1999. Two of all patients had been studied by barium swallowing study. In 51 patients, twenty-four had a primary tumor in the larynx, 8 in the oropharynx, 6 in the nasopharynx, 6 in the oral cavity, 6 in the hypopharynx, and 1 in the nasal cavity. Endoscopically pathologic lesions were biopsied. In control group, endoscopy was performed on 1097 patients who didn't complain any symptoms. Results: Endoscopy showed early malignant lesions in 4 cases(7.7%). Histology of esophageal cancers showed squamous cell carcinoma. Malignant lesions of stomach in 2 cases were histologically identified as adenocarcinoma. Two esophageal cancers occurred in patients whose primary lesions had oropharynx and hypopharynx. Two cases of gastric cancer were also accompanied by oropharynx and hypopharynx. The incidence of second primary cancer was 2 in oropharynx and 2 in hypopharynx. In all cases, second primary cancers were found simultaneously. In control group, 9(0.8%) of 1097 patients were confirmed as early esophageal and gastric cancers. Conclusion: The majority of esophageal and gastric cancer detected by endoscopy were early stage in both head and neck cancer and control group. The incidence of esophageal and gastric cancer of head and neck cancer patients was 10 times as high as that of control group. Although followup period was short, all second primary cancers were detected simultaneously. We would recommend that endoscopic evaluation be included in the workup and followup of all patients with newly diagnosed head and neck cancer.

Ficus carica L. (common fig), one of the first plants cultivated by humans, originated in the Mediterranean basin and currently grows worldwide, including southwest Asia and South Korea. It has been used as a traditional medicine for treatment of metabolic, cardiovascular, and respiratory diseases as well as hemorrhoids and skin infections. Its pharmacological properties have recently been studied in detail, but research on the anti-cancer effect of its latex has been only been studied on a limited basis on several cell lines, such prostate cancer, breast cancer, and leukemia. In this study, we investigated the anti-cancer activity of the latex of Ficus carica L.and its underlying mechanism in FaDu human hypopharynx squamous carcinoma cells. (See Ed. note above) We confirmed through SDS-PAGE analysis and gelatinolytic activity analysis that the latex of Ficus carica contains cysteine protease ficin. Our data showed that the latex inhibited cell growth in a dose-dependent manner. In addition, the latex treatment markedly induced apoptosis in FaDu cells as determined by FACS analysis, elevated expression level of cleaved caspase-9, -3 and PARP (poly (ADP-ribose) polymerase), and. increased the expression of Bax (pro-apoptotic factor) while decreasing the expression of Bcl-2 (anti-apoptotic factor). Taken together, these results suggested that latex containing the ficin inhibited cell growth and induced apoptosis by caspase and the Bcl-2 family signaling pathway in FaDu human hypopharynx squamous carcinoma cells. These findings point to the potential of latex of Ficus carica to provide a novel chemotherapeutic drug due to its growth inhibition effects and induction of apoptosis in human oral cancer cells.
