The radial forearm free flap (RFFF) has become a workhorse flap as a means of reconstructing surgical defects in the head and neck region. We have transferred 12 RFFFs with fasciocutaneous type on oral cavity defects in 12 patients after cancer resection and submucous fibrotic lesion ablation from 2005 to 2007 at Department of oral and maxillofacial surgery, Pusan National University Hospital. We reviewed retrospectively patients' charts and followed up the patients. Clinical analysis on the cases with RFFFs focusing on flap morbidity, indications and available vessels was done. The results of study are follows: 1. RFFF could be applied for all kind of defects after resection of tongue, floor of mouth, buccal mucosa, denuded bone of palate, maxilla, and mandible. 2. All free flaps could be used for primary reconstruction. The survival rate of 12 RFFFs was 92%. Partial marginal loss of the flaps was shown as 3 cases among 12 cases. Large size-vessels like superior thyroid artery, facial artery, internal jugular vein were favorable for microvascular anastomosis. 3. Parenteral nutrition instead of nasal L-tube also can be favorable for postoperative a week for better healing of the flap if the patients couldn't be tolerable with nasal tubing. 4. Donor sites with thigh skin graft were repaired with wrist band for 2 weeks. The complications included scarring, abnormal sensation on hand, and reduced grip strength in few patients, but those didn't induce major side effects. 5. Most RFFFs were well healed even if mortality rate of cancer patients was shown as 50% (5/10 persons). The mortality of patients was not correlated with morbidity of the flaps. We could identify the usefulness of RFFF for restoration of oral function, esthetics if the flap design, tissue transfer indications, and well controlled operation are proceeded.

Lymphangioma is a rare benign congenital tumor of the lymphatic system, which is commonly diagnosed before 2 years of age. In the natronal report, cystic lymphangioma was usually reported as a huge translucent mass located in the head and neck area. It's occurrence in retropharyngeal space with respiratory obstruction and swallowing difficulty in neonate is extremely rare and postoperative nasopharyngeal reflux has rarely been reported. Complete resection is the standard therapy. However, involvement of the upper airway may be determining prognosis in the extensive lymphangiomas because of the difficulty of complete excision. We present a case of cystic lymphangioma in neonate which was initially asymptomatic but gradually progressed to cause respiratory obstruction due to enlargement. After resection, nasopharyngeal reflux developed with dysfunction of the soft palate and gradually improved with conservative care over 5 months.

Purpose: To analyse the risk factors for recurrence of hemangiomas in extremities after surgical treatment and to compare with those of trunk. Materials and Methods: 120 cases of hemangioma with surgical treatments from June 1998 to September 2009 were analysed. 53 cases with surgical treatment on trunk in the same period were set to be the control group. We analyze several factors: age, location, site, size, histologic types and correlation between recurrence and each risk factor using logistic regression analysis. Results: Recurrence rate was 11.7% in extremities and 9.4% in trunk. There were no correlation between recurrence and age, site, size, histologic type. But, there was stastically significant correlation between recurrence rate and location, especially hand, forearm, feet in extremities and head and neck in trunk. Conclusion: Recurrence after surgical treatment of hemangioma is highly prevalent in anatomical location such as, hand, foot and forearm those are difficult to achieve complete resection because of close to neurovascular structures. Careful observation should be needed owing to incomplete resection can occurs recurrence.

Osteosarcoma is a primary malignant tumor arising most often in the long bone, but rare in jaw bone. Especially osteogenic sarcoma of the mandible is a rare tumor, comprising less than 0.5% of all head and neck tumors. Osteosarcoma occurs chiefly in young persons, and presenting very survival rates. Histopathologically this tumor can be classified three types, osteoblastic, fibroblastic, chondroblastic and classified from low grade to high grade by anaplasia or mitosis of the tumor cells. Sometimes, the exact diagnosis of osteosarcoma is difficult especially in low grade osteosarcoma, even if clinical or radiographical findings suggest to osteosarcoma. So suspcious to malignant bone tumor in clinical or radiological findings, biopsy should be taked from deep portion and multiple area, and sharing the patient history and radiographs with pathologist will assist in the development of the diagnosis. We report a case of low grade osteosarcoma on the mandible initially difficulty in accurate diagnosis. The patient visited our hospital for routine dental treatment but radiographic findings displayed ill-defined radiolucency with osteoid formation on the mandible. Final diagnosis was difficulty in initial biopsy but subsequent biopsy taked from deep portion presented infiltrative growth and mitosis of the tumor cell in some area with small osteoid bone formation, so we could reach final diagnosis as low grade sarcoma. We treated this patient with bloc resection of the mandible and immediate reconstruction with iliac corticocancellous block.
Thyroid cancer, the most common cancer of endocrine neoplasms, has tremendous variation in tumor biologic behavior. There is no consensus about treatment mode to prevent recurrences despite of recent advance in understanding characteristics of thyroid cancer. So, we have made a clinical analysis and follow-up study of recurred 27 cases among 189 cases treated under the diagnosis of thyroid carcinoma in the department of surgery, Chonnam University Hospital from February, 1982 to February, 1992 to clarify our experience about the characteristics of recurred thyroid cancer. The results were as follow: According to the pathological classification of recurred thyroid cancer, recurrence rate was 11.6% in papillary carcinoma, 15.6% in follicular carcinoma, 37.5% in medullary carcinoma, 66.7% in undifferentiated carcinoma, respectively, and the mean recurrence rate of thyroid cancer was 14.3%. The recurrence rate according to age was 28.6% in 8th decade and 17.9% in 4th decade. The recurrence rate according to sex was not singificant(15.6% in male: 14% in female). The mean period to relapse was 4 years 6 months in papillary carcinoma, 2 years 5 months in follicular carcinoma, 2 years 1 months in medullary carcinoma, 2 years 6 months in undifferentiated carcinoma. The recurrence rate according to previous operating methods, such as performing lymph node dissection or not, mode of thyridectomy, type of lymph node dissection was statisfically non-specific. Common recurrent sites of papillary and follicular carcinoma was cervical lymph node and remained thyroid tissue. Medullary and undifferentiated carcinoma was noted in multiregional or systemic involvement Reoperation was performed with complete resection of recurred or metastatic mass, such as radical neck dissection or mass extirpation from involved organs as possible. The postoperative complications were 2 cases of horseness, and 1 case with hematoma, transient hypocalcemia, wound infection, and pulmonary insufficency, respectively. 5-year survival rate was 85.5% in papillary carcinoma, 66.7% in follicular carcinoma. 50% in medullary carcinoma, and 50% in undifferentiated carcinoma. We concluded that recurrence in thyroid cancer give a reconsideration to previous conservative therapy and more extensive surgical procedures for thyroid cancer including lymphatic dissection are recommanded to prevent recurrences in selected cases if possible.
In spite of remarkable improvement of surgical skills and anesthesia, local failure still occurred in 36-45$ \% $ of locally advanced colorectal cancer after curative resection with or without pre-or post-operative irradiation. Intraoperative radiation therapy(IORT) is the ideal modality which resectable lesions are removed surgically 3nd the remaining cancer nests are sterilized by irradiation during a surgical procedure. Therefore, the excellent local control without the damage of the adjacent normal tissues can be achieved. In IORT, judicious set up of the treatment cone on the treatment surface of the patient is required for accurate and homogenous dose distribution within treatment field, especially on the slopping surface of sacrum and pelvic sidewall which are the common sites of the local recurrence in rectal cancer. For this purpose, adequate co-ordination of gantry rotation and table tilting are essential. Adjusting gantry rotation is not difficult but tilting of the table is impossible inconventional treatment couch. Department of Therapeutic Radiology in Yeungnam University Medical Center developed the IORT table for colorectal cancer which is easy to set up and detach on the Linac treatment couch within 5 minutes. The range of tilting with head-up and head-down is about 30 degree which is efficient and easy-to-use, not only for IORT but also for colorectal surgery. So far, authors performed IORT with newly developed treatment table in 2 patients with rectal cancer and we found that this newly developed table could contribute in improving the dose distribution of IORT and surgical procedure for colorectal cancer.

Thyroid carcinoma ranks low in incidence and as a cause of death when compared to carcinomas arising in the other site. With adequate surgical treatment, the prognosis of operable thyroid carcinoma is good. However, the extent of surgical resection in treatment of thyroid cancer remains still controversy. The aim of this study was to assess the results of thyroid cancer patients treated surgically and to analyze the prognostic factors affecting survival and to improve the survival rate. We retrospectively analyzed the outcome of a total of 278 thyroid cancer patients treated surgically at Inje University Paik Hospital from 1980 to 1995 and followed for 1 to 16 years. There were man in 47 and woman in 231 patients with age range of 14 to 79 years(mean 42 years). Histopathologic findings were papillary carcinoma in 233, follicular carcinoma in 33, mixed carcinoma in 7, medullary carcinoma in 2, and undifferentiated carcinoma in 3 patients, respectively. Operative procedures were unilateral lobectomy in 111, subtotal thyroidectomy in 100, and total thyroidectomy in 67 patients. Central node dissection was performed in 92, modified neck disseciton in 62, radical neck dissection in 28, and no node dissection in 96 patients. Thyroid hormone was administered for the period of 3 to 5 years to suppress endogenous TSH production. Overall 5-year survival rate according to Kaplan-Meier method was 91.1%. Independently, significant factors affecting the prognosis were age at diagnosis, tumor size, pathologic type, tumor stage, lymph node metastasis, angioinvasion, extrathyroidal extension, and 'risk' group category. but, the prognosis were not influenced by sex and capsular invasion. Patients at low risk or with small size carcinomas had long survival over 5 years with only lobectomy. Lymph node dissection was carried out with a limited type in no jugular metastasis, radical neck dissection was performed only therapeutically in proved jugular node metastasis. Fifteen patients were dead of tumor recurrence after surviving for three months to two and half years, and the cause of death was local recurrence in nine, bone metastasis in four and lung metastasis in two patients. In conclusion, more extensive surgery including total thyroidecotmy and systematic compartment-oriented dissection of the lymph node metastases in patient at high-risk group will results in better survival and lower recurrence rate.
Objectives: The best treatment for the malignant parotid tumor still remains to be defined, and a better knowledge about the tumor features that predict the treatment result is needed. The aim of this study is to evaluate the treatment outcomes and to suggest the optimal treatment modality for the parotid cancer. Materials and Methods: The clinicopathologic characteristics of 113 patients who were treated for parotid cancer from January 1990 to December 2002 were retrospectively analysed. Univalate analyses were performed to establish the prognostic influence of pateint age, gender, tumor size, histologic grade and lymph node metastasis. Results: The mean age was 46.4 years old (15-81 years) and. The male to female ratio was 1 : 1.1. The chief complaint was a palpable mass in 85%, pain was in 12.4% and facial nerve palsy was accompanied with 2.7%. The mean tumor size was 3.5cm in diameter. The most common malignant tumor was mucoepidermoid carcinoma (33.6%), followed by acinic cell carcinoma (15%), adenoid cystic carcinoma (11%), carcinoma expleomorhpic adenoma (11%), basal cell carcinoma (7%). The most common operative procedure was total parotidectomy (47.8%) and various types of cervical lymph node dissection were added in 69.9%. Postoperative radiotherapy was done in 61.1 %. Postoperative complications developed in 54 cases (47.8%), including 46 cases (40.7%) of facial nerve palsy and 9 cases (8%) of Frey's syndrome. Recurrences developed in 21 cases (18.6%) and deaths in 15 (13.3%). Cumulative survival at 5 year was 75.4%. Univariate analysis of clinical factors showed that histologic grade and positive cervical lymph node significantly influenced survival (p<0.05). Conclusion: These results suggests that the radical resection with lymph node dissection and postopertaive XRT would be necessary to improve the survival of the patients with high grade cancer or positive lymphnode metastasis.

Background/Objectives: Papillary thyroid carcinoma (PTC) has generally an indolent character with a good prognosis. However, recurrence remains a major concern for the patients during their lifetime. Despite the slowly progressing character of PTC, recurrence can occur within a short period after initial surgery. This study aimed to determine the clinical findings and cause of recurrence in patients who underwent re-operative surgery due to neck node recurrence by reviewing the CT (computed tomographic) scan imaging of the recurrence of PTC retrospectively. Materials & Methods: We reviewed the medical records of patients referred to Ajou University Hospital from January 2002 to January 2018. All patients had re-operative surgery due to neck node recurrence and CT scan results of preoperative evaluation and postoperative follow up. Over this period, 110 patients who underwent re-operation due to neck node recurrence with a CT scan were included in our cohort, resulting in a total of 220 re-operations. Results: The time from initial operation to first re-operation was examined in 110 patients. The median time to re-operation was 28 months, with a range of 4 months to 186 months. Most re-operations (82.7%) occurred within the first five years, 43.6% were in the first two years from the initial surgery. The result of the retrospective CT review showed newly developed cases (21,19.1%), missed diagnosis cases (42,38.2%), real recur cases after surgery (33,30.0%), and remnant lymph nodes (LNs) cases (14,12.7%). We further sub-analyzed 14 cases with remnant LNs. Reasons for remnant LNs included insufficient operation (N=5) and beyond general surgical extent. (N=9). Conclusion: Re-operation due to cervical lymph node recurrence is mostly a persistent disease. They included a missed diagnosis and incomplete operation. These finding may reduce the reoperation of cervical lymph node recurrence by accurate preoperative evaluation and complete surgical resection at the initial surgery.

Background: The two most common skin cancers are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). The purpose of this study was to describe the detailed clinical behavior of BCC and SCC in the head and neck region over 19 years at a single institution. Methods: A retrospective analysis was performed for all patients with non-melanoma skin cancer who had undergone surgical resection over an 18-year period. Patient charts were reviewed for demographic information, tumor size, onset-to-diagnosis, anatomic location, clinical subtype, histologic differentiation, method of surgical treatment, and recurrence. Results: The review identified 265 cases of either BCC or SCC in 226 patients. Of the 226 patients, 80 (35.4%) were men and 146 (64.6%) were women. BCC (n=138, 55.9%) was more frequent than SCC (109, 44.1%). The most frequent age group was 70-to-79 year olds (45 patients, 35.2%) for BCC and 80-to-89 year olds (41 patients, 41.8%) for SCC. By aesthetic units of the face, the most common location was the nasal unit (44 cases, 31.9%) for BCC and the buccal unit (23 cases, 21.1%) for SCC. The most common clinical subtype of BCC was the nodular type (80 cases, 58.0%). Local flaps were most commonly used to cover surgical defects (136 cases, 55.1%). Recurrent rates were 2.2% for BCC and 5.5% for SCC. Conclusion: In our study, many characteristics of BCC and SCC were compared to previously published reports were generally similar, except the ratio of BCC to SCC. Further study can help to establish the characteristics of BCC and SCC.
