Wide vertical hemilaryngopharyngectomy with immediate glottic and pharyngeal reconstruction using a radial forearm free flap is reported in 1991 by Chantrain et al. This procedure was designed for the preservation of healthy hemilarynx and resection of pharynx with safe oncological margin in especially piriform sinus cancer or supraglottic cancer invading the hypopharynx. In the original paper, they used palmaris longus tendon for reconstruction of neoglottis. In other groups, they used rib cartilage instead of palmaris longus tendon. In this paper, we report two cases of piriform sinus cancer patients who treated with wide vertical hemilaryngectomy with radial forearm free flap reconstruction. In one case, the operation was performed as Chantrain et al described. But in another case, the ipsilateral forearm was impossible due to the positive Allen's test. So the contralateral forearm flap and rib cartilage graft was done. This reconstructive technique make large resection possible. As the dissection of thyroid cartilage and lateral displacement makes direct visualization and manipulation of piriform sinus lesions, sufficient resection margin in lateral and inferior pharyngeal wall cab be obtained.

Organ preservation surgery and minimally invasive surgery have been developed during the past 20 years with major focus on transoral laser surgery, endoscopic surgery, and robotic surgery. Two major robotic surgeries in head and neck area are transoral robotic surgery (TORS) and robotic thyroidectomy. Transoral robotic surgery is a safe and efficacious method of surgical treatment of oropharyngeal. hypopharyngeal and laryngeal neoplasm. Advantages of the technique include adequate ability to visualize and manipulate lesions with two hands. TORS can provide magnified three dimensional views and overcome the limitation resulting from the "line of sight" which hinders transoral laser procedure. The swallowing function following transoral robotic surgery show superior and patients were able to retain or rapidly regain swallowing function in the majority of cases. Recently, robotic thyroidectomy has also been developed to overcome the [imitation of endoscopic thyroidectomy. Robotic thyroidectomy by a gasless unilateral axillo-breast or axillary approach using a da Vinci S Surgical Robot is a feasible and cosmetically excellent procedure. It can be a promising alternative to endoscopic thyroidectomy or conventional open thyroidectomy.

Background and Objectives: Standard treatment of locally advanced laryngeal, hypopharyngeal, and some oropharyngeal cancers includes total laryngectomy. In an attempt to preserve the larynx through induction chemotherapy, we designed induction chemotherapy followed by definitive radiation in patients with potentially respectable head and neck cancer to determine whether organ preservation is feasible without apparent compromise of survival. Materials and Methods: The twenty-six patients diagnosed advanced head and neck squamous cell carcinoma, Stage III or IV (AJCC 2002) and performed organ preservation protocols in Ajou university hospital from 1994 to 2001 were included in this study. Results: Neoadjuvant chemotherapy showed an overall response rate of 84.6% and a complete remission (CR) rate was 59.1% following neoadjuvant chemotherapy and radiation. Seven of thirteen patients were able to preserve their larynges for more than two years by chemotherapy and radiation. There were no treatment related mortality after 2 cycles of induction chemotherapy. Conclusion: Although Organ preservation protocol through neoadjuvant chemotherapy and radiation need more controlled randomized study, it was considered alternative treatment modality in advanced head and neck cancer.

Plummer-Vinson(Paterson-Kelly) 증후군은 임상적으로 상부식도 혹은 하인두의 막양구조(web)와 이로 인한 연하곤란, 철분결핍성 빈혈, 그리고 구강점막의 위축성 변화를 동반하는 질환으로, 식도암을 유발하는 전암성 병변으로, 일반적으로 경구 철분 투여만으로 증상을 호전시키거나 내시경을 이용한 풍선확장술이나 전기소작술 치료가 주로 시행되고 있다. 본 병원에서는 63 세 여자환자에게서 나타난 상부식도의 협착을 유발한 병변에 대하여 공장 이식편을 이용한 유리이식술 치료한 후, 병리조직학적인 검사에서 상피내암종으로 진행한 Plummer-Vinson 증후군으로 판명되었기에 이를 보고하고자 한다.

Reconstruction of the pharynx and cervical esophagus presents a tremendous challenges to surgeons. Over the past 2 years[1990, Dec.-1993, Jun], the free jejunal graft has been performed in 17 cases in Korea Cancer Center Hospital.The indications of this procedures were almost malignant neoplasms involving neck and upper aero-digestive tract; Hypopharyngeal cancer[12 cases, including 2 recurrent cases], laryngeal cancer[2 cases], thyroid cancer[2 cases, including 1 recurrent case], cervical esophageal cancer[1 case]. There were fifteen men and two women, and the mean age was 59.6 years. The anastomosis site of jejunal artery were common carotid artery[16 cases] or external carotid artery[1 case] and that of jejunal vein were internal jegular [15 cases] or facial[1 case] and superior thyroid vein[1 case]. The length of jejunal graft was from 9 cm to 17 cm[mean 13 cm] and the mean ischemic time was 68 minutes. There was one hospital mortality which was irrelevant to procedures[variceal bleeding] and one graft failure[1/16]. Other postoperative complications were neck bleeding or hematoma[3 cases], abdominal wound infection or disruption[5 cases], anastomosis site leakage[1 case], pneumonia[2 cases], graft vein thrombosis[1 case], and food aspiration[1 case]. The function of conduit was excellent and ingestion of food was possible in nearly all cases. Postoperative adjuvant radiation therapy was also applicable without problem in 7 cases. During follow-up periods, the anastomosis site stenosis developed in four patients, and the tracheal stoma was narrowed in one case but easily overcome with dilation. In conclusion, we think that the free jejunal graft is one of the excellent reconstruction methods of upper digestive tract, especially after radical resection of malignant neoplasm in neck with a high success rate and low mortality and morbidity rate.

Background and Objectives: The reconstruction is very important in Head and neck cancer surgery to repair the defect created by resection of tumors, to enable successful wound healing, to restore function and to provide acceptable cosmesis. The radial forearm free flap has been the most useful reconstructive flap because it provides a moderate amount of thin, pliable, relatively hairless skin and comparatively simple to do with minimal morbidity. The aims of this study is to estimate the outcome of the reconstruction with radial forearm free flap with the several factors in 140 head and neck cancer cases in our hospital for last 10 years. Materials and Methods: Retrospective review of the records of 140 patients underwent resection of the head and neck tumors and reconstruction with a radial forearm free flap from 1993 to 2003. The age, sex of the patients, Primary site, the complication of donor and recipient site, flap survival rate, median time to start diet, patient subjective symtoms about swallowing and articulating and the fact of revision reconstructive surgery were analyzed. Results: In primary pathologic site, 56 cases were oral cavity cancers, 44 cases, oropharyngeal cancers and 22 cases, hypopharyngeal cancers. Flap survival rate was 93.6% (13 leases). On donor site, wound dehiscence, hematoma, sensory change and infection were noted and on recipient site, most common complication were fistula and wound dehiscence. The complication rate of recipient's site was 19.1 % and donor site, 3.5%. In 118 cases (84.3%), the patients could take all kinds of food. Swallowing difficulty were noted in 22 cases 05.7%). In 5 cases, there was articulation difficulty but most of patients except patients having total laryngectomy (18 cases) couldn't have any difficulty in articulation and speaking. Conclusion: We conclude that the radial forearm free flap is the most appropriate reconstructive material for treating the defect in head and neck reconstruction.
