Background: To avoid the major mobidity associated with bilateral radical neck dissection, modified radical neck dissection has become established as an effective adjunctive procedure in the management of head and neck cancer. But several studies reported early postoperative internal jugular vein(IJV) occlusion in patients who underwent modified radical neck dissection. Objectives: To determine internal jugular vein patency following modified radical neck dessection performed in various head and neck cancer and to identify factors associated with venous occlusion. Materials and Methods: From Aug. 1996 to Oct. 1997, twenty three patients underwent either unilateral or bilateral modified radical neck dissection; 19 males and 4 females, ranging in age from 28 to 75 were retrospectively examined. All patients had a preoperative doppler imaging or CT or both for their initial evaluation. A follow-up examination was obtained(after a minimum postoperative period of 2 months and a maximum one of 4 months). Results: Thirty-four IJVs were examined. All but six IJVs examined were found patent postoperatively. The preservation rate of patency of the IJV in modified radical neck dissection was found to be high(28 of 34 IJVs or 82%). Conclusion: The preservation rate of patency of the IJV in modified radical neck dissection was found to be high. These results favor the use of modified radical neck dissection for IJV preservation, particularly in bilateral neck dissection. A retrospective chart review revealed that trauma of the vessel and extrinsic compression of the vein by the musculocutaneous flap or recurrent carcinoma in the neck may be the cause of the vein occlusion.

The authors present 15 cases in which the diagnosis of thyroid cancer was established pathologically among 300 cases of Graves' disease diagnosed clinically at Chosun University Hospital, from January 1982 to December 1994. These cases were analyzed in order to establish guidelines for prophylactic node dissection as part of the initial management of thyroid cancer in patients with Graves' disease. The analysis revealed the following: 1) The average age of the 15 patients was 34.5 years and the male: female ratio was 1 : 4.0. 2) In 8 of the 15 cases(53.5 %) the occult thyroid carcinoma measured less than 1.5cm. 3) The degree of invasivensess manifested in these fifteen cases may be summarized as follows: In Group 1(6 cases) there was absence of microscopic capsular invasion and of lymphnode metastasis. In Group 11(4 cases) threre was microscopic capsular invasion but absence of lymphnode metastasis: In Group III(4 cases) there was either extrathyrodal soft tissue invasion or regional lymph node metastasis: and in Group IV(1 case) there was lymphnode invasion and distant metastasis. 4) Thirteen patients underwent either subtotal or near total thyroidectomy, and 2 patients underwent total thyroidectomy. Seven patients underwent some type of neck dissection, as follows: anterior compartment dissection in one of the cases in Group I; functional neck dissection in two cases and jugular node dissection in one case in Group II; and anterior compartment dissection in one case and modified radical neck dissection in two cases in Group III. 5) The author propose the following guidelines for prophylactic initial node dissection when a unexpected coexisting thyroid carcinoma in encountered on the frozen section during the surgical management of Graves' disease; Group I cases do not require initial neck dissection in group II, anterior compartment dissection in sufficient. In Group III, either jugular node dissection or functional neck dissection should be performed, and followed by postoperative Ra$^{131}$I therapy, Group IV requires Ra$^{131}$I therapy with or without modified radical neck dissection depending in the patient's condition.

Although the vast majority (about 70%) of patients with cancer will have pain directly related to neoplastic invasion into pain-sensitive bone and soft tissue structures,as many as 20% of the adults will have pain caused directly by cancer therapy. Treatment related pain problems are important for several reasons; their appearance may be confused with more omnious pain syndromes associated with tumor recurrence or progression that may be directly lead to death of the patient; when severe, compliance with recommandations for further therapy may be adversely affected. Now, we report a case of postsurgical pain syndrome after radical neck dissection in a patient with tonsilar cancer. The pain after radical neck dissection result from injury to the cervical plexus,cranial nerve,and cervical sympathetics. In our case, we ruled out soft tissue infection and tumor recurrence,and successfully treated with gasserian ganglion block with pure alcohol in the patient having neuropathic pain in the mandible and preauricular region after radical neck dissection.

Purpose: The purpose of this study is to evaluate the transverse cervical artery of those who received preoperative radiotherapy or radical neck dissection and those who are unable to utilize the branch of external carotid artery system, which are most commonly used as recipient artery in head and neck reconstruction. Methods: 10 patients were selected as head and neck cancer candidates for study. 8 patients received radical neck dissection or modified radical neck dissection and 3 patients underwent preoperative radiotheraphy. In call cases, reconstruction using free flap was performed with transverse cervical artery as recipient artery and posterolateral cervical vein or transverse cervical vein as recipient vein. Results: Partial necrosis of flap due to wound infection was noted in one case and successful microsurgery was achieved in all other cases. The average pedicle length was 9.3 cm and all arteries underwent end to-end anastomosis. In 7 patients, posterolateral cervical vein was used as recipient artery and transverse cervical vein was utilized in 3 patients. Conclusion: In cases where recipient artery from external carotid system cannot be utilized due to preoperative radiotherapy or radical neck dissection, the transverse cervical artery can be an alternative option of choice. Due to diverse variations of transverse cervical vein as a recipient vein, the posterolateral cervical vein may be considered in such cases.

Background and objectives : There may be frequent lymphatic neck metastasis among supraglottic cancer patients after their primary surgery. The aim of this study was to evaluate the effectiveness of prophylactic neck dissections in supraglottic cancer patients to lower the neck metastasis. Material and method : The authors retrospectively reviewed medical records of 52 patients (7 females. 45 males) who had received the operations for the supraglottic cancer from 1995 to 2000. They were preoperatively examined with Computer Tomographic images, and also examined by the cervical neck palpations. Postoperative pathologic specimens were reviewed and the Pathologic stagings were confirmed by the pathologist. Results : Among 52 patients who received surgery for supraglottic carcinoma, 5 patients received ipsilateral neck dissection, 12 patients received ipsilateral neck dissection with postoperative radiation therapy, 10 Patients received bilateral neck dissection and 25 patients received bilateral neck dissection with postoperative radiation treatment. In comparison of the data of N0 to N+ conversion rate of neck, there were 11 ipsilateral T3 N0 patients and 2 patients(18%) were converted to N+ status, and there were 8 Patients with T4 N0 stages, and 3 patients(38%) were converted to N+ status. In comparing the data of contralateral neck dissection on N0 patient, there were 8 patients of T3 N0 patients, and there was 1 patient (13%) who showed recurrence. There were 5 patients of T4 N0 stages and there was 1(20%) patient with recurrences. When the ipsilateral N stages were N2a, and N2b, there 1 case of contraleral N+ conversions, respectively. In recurrences, there were 2 patients of N2b staged patients and 1 patient of N2c patient that showed recurrence during the follow up period. Conclusion : This data shows that at least an ipsilateral neck dissection is necessary in order to prevent the recurrences, and also suggests that bilateral neck dissection is necessary for the higher T stage. Since the higher N staged patients showed higher rate of recurrence, so that neck dissection is mandatory for the higher N staged patients.

Late complications of head and neck cancer survivors include neck muscle atrophy and soft-tissue fibrosis. We present an autopsy case of neck muscle atrophy and soft-tissue fibrosis (sternocleidomastoid, omohyoid, digastric, sternohyoid, sternothyroid, and platysma muscles) within the radiation field after modified radical neck dissection type I and postoperative radiotherapy for floor of mouth cancer. A 70-year-old man underwent primary tumor resection of the left floor of mouth, left marginal mandibulectomy, left modified radical neck dissection type I, and reconstruction with a radial forearm free flap. The patient received adjuvant radiotherapy. The dose to the primary tumor bed and involved neck nodes was 63 Gy in 35 fractions over 7 weeks. Areas of subclinical disease (left lower neck) received 50 Gy in 25 fractions over 5 weeks. Adjuvant chemotherapy was not administered.

Chylous fistula is a rare complication occurring after radical neck dissection. Previous reports on neck dissection described an incidence of about 1% to 2%. We report a case of chylous fistula that occurred after radical neck dissection for squamous cell carcinoma of left lower gingiva and mandible in a 52-year-old man. We successfully managed the fistula by the following conservative measures : bed rest with head elevation, continuation of closed suction drainage, and dietary management to decrease the rate of chyle formation.

Background: The author analyse the impact of extracapsular lymph node spread and bone engagement in the ipsilateral neck of patients suffering squamous cell carcinoma (SCC) of the lower lip. Methods: The data of 56 neck dissections performed in patients suffering SCC of the lower lip between January 2000 and December 2008 were retrospectively analysed. Statistical analysis was performed with the Kaplan-Meier life table method, and the survival rate was investigated with the log rank statistic and significance test. The values were considered statistically significant at p<0.05. Results: Nine patients took advantage from simultaneous treatment of tumor and prophylactic neck dissection (level I-III), reaching 100% survival rate. Patients suffering metastasized disease, who received radical neck dissection at the time of tumor treatment, presented 83.3% survival rate. Patients who underwent previous surgery and radiotherapy presented worse prognosis although radical neck dissection in case of extra-capsular spread only (24.7%) and osseous engagement (22.2%). Conclusion: Prophylactic neck dissection (level I-III) is recommended in T3-T4 N0 SCC. Simultaneous treatment of tumor and cervical lymph nodes provides a better prognosis as respect to delayed nodal management. Extra-capsular spread with or without bone engagement represents independent risk factor responsible for high mortality rate of SCC of the lower lip.
