A multivariate analysis of the prognostic factors and five year survival rate was carried out on a series of 72 thyroid cancers treated surgically from 1980 to 1987 and followed for 1 to 11 years. The prognosis of the disease was significantly influenced by age at diagnosis, extracapsular invasion, angioinvasion and pathologic type, but the disease was not influenced by sex, lymph node metastasis, and 'risk' category. The overall five year survival rate was 89.7%. Six patients were dead of tumor after surviving for six months to two and half years, and the cause of death was local recurrence in three, lung metastasis in two and bone metastasis in one patient. Five year survival rate in age above fifty, presence of capsule and angioinvasion, follicular carcinoma, and extrathyroidal lesion was significantly shorter than that of patients with age below fifty, absence of capsule and angioinvasion, papillary carcinoma, and intrathyroidal lesion. Patients at low risk or with small carcinomas had long survival over 5 years with only lobectomy. Lymph node dissection was done with a limited type in no jugular metastasis, radical neck disscetion was performed only therapeutically in proved jugular node metastasis. Thyroid hormone was administered for the period of 3 to 5 years to suppress endogenous TSH production.

Fine needle aspiration cytology as a diagnostic workup of parotid gland tumor is a simple and useful method. Although fine needle aspiration cytology could not predict accurate diagnosis in all cases, it is usually helpful in differentiating malignancy and benign lesions. A 35-year-old female was found to have a parotid mass for 1 year. Preoperative evaluation including computed tomography and magnetic resonance imaging were non-diagnostic, but, fine needle aspiration cytology on parotid mass showed the suspicion of a low-grade mucoepidermoid carcinoma. Superficial parotidectomy and selective neck node dissection were done based on cytology. However, final pathological examination confirmed benign pleomorphic adenoma. Here, the diagnostic accuracy and cautions in interpretation of result of fine needle aspiration cytology is discussed with respect to the case.

Objective : Stent-assisted coiling on intracranial aneurysm has been considered as an effective technique and has made the complex aneurysms amenable to coiling. To achieve reconstruction of intracranial vessels with preservation of parent artery the use of stents has the greatest potential for assisted coiling. We report the results of our experiences in ruptured wide-necked intracranial aneurysms using Y-stent coiling. Methods : From October 2003 to October 2011, 12 patients (3 men, 9 women; mean age, 62.6) harboring 12 complex ruptured aneurysms (3 middle cerebral artery, 9 basilar tip) were treated by Y-stent coiling by using self-expandable intracranial stents. Procedural complications, clinical outcome, and initial and midterm angiographic results were evaluated. The definition of broad-necked aneurysm is neck diameter over than 4 mm or an aneurysm with a neck diameter smaller than 4 mm in which the dome/neck ratio was less than 2. Results : In all patients, the aneurysm was successfully occluded with no apparent procedure-related complication. There was no evidence of thromboembolic complication, arterial dissection and spasm during procedure. Follow-up studies showed stable and complete occlusion of the aneurysm in all patients with no neurologic deficits. Conclusion : The present study did show that the Y-stent coiling seemed to facilitate endovascular treatment of ruptured wide-necked intracranial aneurysms. More clinical data with longer follow-up are needed to establish the role of Y-stent coiling in ruptured aneurysms.

Mucosal melanoma of the head and neck is a rare and usually lethal disease. Primary laryngeal malignant melanoma(LMM) are exceedingly rare tumors that morphologically are readily confused with more common types of laryngeal cancer. Treatment of choice for LMM is complete surgical excision and elective lymph node dissection is usually not recommended. The use of radiation or chemotherapy is generally thought to have no effect on local or distant disease and currently used as adjuvant therapy. The prognosis is extremely poor. We have experienced a 61 year old male patient with symptoms of foreign body and lump sense in throat. A dark pigmented polypoid mass was found on the right aryepiglottic folds with normal mobility of vocal cord. Total laryngectomy was performed under the diagnosis of malignant melanoma. Bone scan revealed multiple bony metastasis on ribs and lumbar vertebrae after 5 months of operation. There have been no evidence of recurrence at primary area. The patient died after 8 months of operation.

Background and Objectives: Silicone, Gore- Tex, Gelfoam, Collagen and autologous fat are used for thyroplasty in case of vocal fold paralysis or paresis. These implants have many advantages, such as biocompatibility, low price and easy handling and accessibility. But additional voice modification is impossible using these materials. So, we design new thyroplasty technique, called balloon thyroplasty using Foley catheter. Materal and Methods: The fresh human larynx was dissected in midline posteriorly. Minithyrotomy hole was created using 5mm cutting burr in the midline of thyroid cartilage. Subperichondrial dissection was done using Duckbill elevator up to vocal process. Balloon catheter(1.5cm balloon size) was inserted through the subperichondrial tunnel. The balloon was inflated to medialize the vocal cord. Results: After ballooning, the true vocal cord medialized mimicking thyroplasty. Conclusion: The authors found that Balloon thyroplasty could be a good candidate for vocal fold medialization technique. The technical refinement and in vivo safety are reserved for the ongoing study.

Secretory carcinoma of salivary gland origin is a recently described tumor that harbors a characteristic ETV6-NTRK3 translocation that is identical to secretory carcinoma of the breast. The majority of tumors were located in the parotid gland and other major salivary glands, while the minority occurred in a minor salivary gland. We present a case of a 71-year-old female who was diagnosed with low-grade salivary gland cancer presenting in the soft palate accompanying lymph node metastasis. Peroral wide excision, selective neck dissection, reconstruction with radial forearm free flap was performed. The final pathology report indicated secretory carcinoma of the soft palate. The patient was followed-up without evidence of recurrence for one year. At present, it is difficult to accurately assess prognosis and treatment for the secretory carcinoma of the minor salivary gland origin. Continuous follow-up with various cases is needed further.

A retrospective investigation of 52 cases of carcinoma of the larynx, who underwent total laryngectomy $\bar{c}\;or\;\bar{s}$ neck dissection at Pusan National University Hospital from 1978 to 1985, was performed. The results obtained were as follows: 1) There were 32 glottic(62.7%), 18 supraglottic(35.3%) and 1 subglottic(2.0%) carcinoma. 2) In stage grouping, stage ill was the most(64.7%) and then stage II, stage IV, stage I in order. 3) Overall rate of cervical metastasis was 29.4%. In glottic carcinoma, 0% of $T_1,\;40%\;of\;T_2,\;18%\;of\;T_3\;and\;25%\;of\;T_4$. In supraglottic carcinoma, there was 0% of $T_1,\;29%\;of\;T_2,\;56%\;of\;T_3\;and\;50%\;of\;T_4$. 4) The incidence of postoperative complication was 31.4% and stomal stenosis was the most(13.7%) 5) There were 8 cases of local recurrence and 3 cases of distant metastasis(2 cases in lung, 1 case in esophagus) among 40 cases which were able to follow up. 6) 3 year estimated survival rate for glottic and supraglottic carcinoma were 73.3 % and 85.7% respectively.

During a 9-year period(March 1985 to February 1994), 111 consecutive total thyroidectomies and modified or radical neck dissections were performed at 81. Vincent Hospital, Catholic University Medical College, for benign and malignant disease. There were three permanent complications, persistent hypoparathyroidism, in total thyroidectomies. Overall complications were observed 20(62.5%) in benign diseases, 47(59.5%) in malignancy. In benign and malignant thyroid diseases. the complications were transient hypoparathyroidisms (28.8%), transient hoarsenesses(21.6%), wound infections (3.6%), bleedings(3.6%), and permanent hypoparathyroidisms(2.7%). Our experience suggests that the morbidity of total thyroidectomy relates primarily to the extracapsular extension, necessitating en bloc exision accompanied by additional lymph node dissection. The low incidence of permanent complications in thyroid disease suggests the feasibility of total thyroidectomy as the operation of choice when surgeons are familiar with the technique and indications.

Objectives: Various techniques of endoscopic thyroidectomy have been developed in thyroid resection since 1998 in the aspect of excellent cosmetic viewpoint. Of them, we evaluated our experiences and advantages of gasless axillary approach technique for resection of dominant thyroid nodules. Material and Methods: Twenty-nine cases of thyroid nodules were operated by the technique of gasless axillary approach during one year from December 2003 to December 2004. Twenty four patients underwent total lobectomy and five patients were partial lobectomy. Results: The operation time of first case took 300 minutes, however it became gradually shortened with case experiences down to 100-120 minutes. Pathologically, nodular hyperplasia was twenty cases, follicular adenoma five cases, papillary carcinoma three patients, and Hashimoto's thyroiditis one patient. There was no case of conversion to open thyroidectomy. Three cases of postoperative hoarseness were recovered spontaneously in 3 months. Hospital stay was four days for most patients. The cosmetic result was excellent without visible scar in anterior neck and chest. Conclusion: Endoscopic thyroidectomy via gasless axillary approach shows excellent result in cosmetic view point with hidden incision scar at axilla, and shorter hospitalization. However a question of longer operation time for dissection of the long plane over pectoral muscle is still remained.

Laryngeal lymphoepithelial carcinoma (LEC) is a rare tumor with only 34 cases in the published literature. Epidemiologically, laryngeal LEC is extremely rare in Asian. Originally, LEC is a common type of carcinoma in nasopharynx. Laryngeal LEC resembles nasopharyngeal LEC, except that most cases of laryngeal LEC are not associated with Epstein-Barr virus. We present a case of laryngeal LEC which developed at the left false cord extending to true vocal cord, para-glottic space and pre-epiglottic space. Total laryngectomy with bilateral neck dissection was performed. LEC was reported as biopsy confirmation result. The patient underwent postoperative radiotherapy and showed no evidence of recurrence during follow-up period of 42 months. In consideration that LEC in larynx have not been reported in South Korea yet, we introduce the clinical features and treatment outcomes of laryngeal LEC with literature review.
