Purpose: The resection of locally advanced or recurred breast cancers frequently result in large chest wall defects and it leads to a great challenges to cover. Generally simple skin grafts are not a practical option for patients because of their poor cosmetic appearance and prognosis. The latissimus dorsi and rectus abdominis musculocutaneous flap have traditionally been recommended for closure of these large defects. Though the cosmetic result of reconstruction using these flaps is often excellent, but has significant drawbacks. Therefore, we thought that chest wall reconstruction using the external oblique musculocutaneous flap can be an alternative method for extensive chest wall defect related to large, locally advanced breast carcinoma. Methods & Results: We present a case of a 50-year-old Korean female, refered to our department with a left breast tumor for 10 months. CT demonstrate a large tumor on the left anterior chest wall and multiple nodules of varying size in the cervical areas and liver. FDG-PET showed areas of hot uptake throughout the left chest wall, mediastinum and liver. Biopsy was consistent with invasive ductal carcinoma (Grade III). The initial tumor was considered inoperable, so a series of chemotherapy was initiated. Though the size of the breast mass was slightly decreased, the patient continued to suffer from purulent discharge, unpleasant odor and contact bleeding of the mass, the salvage mastectomy was performed. Conclusion: We could reconstruct $23{\times}16\;cm$ sized large chest wall defect, resulting from the resection of a locally advanced breast carcinoma, using an external oblique musculocutaneous flap successfully. Immediate postoperatively checked flap was healthy. Overall result was good without any significant complications and discharged 3 weeks after operation.

A rare case of atlantoaxial rotatory subluxation occurred after pediatric cervical spine surgery performed to remove a dumbbell-shaped meningioma at the level of the C1/C2 vertebrae. This case is classified as a post-surgical atlantoaxial rotatory subluxation, but has a very rare morphology that has not previously been reported. Although there are several reports about post-surgical atlantoaxial rotatory subluxation, an important point of this case is that it might be directly related to the spinal cord surgery in C1/C2 level. On day 6 after surgery, the patient presented with the Cock Robin position, and a computed tomography scan revealed a normal type of atlantoaxial rotatory subluxation. Manual reduction was performed followed by external fixation with a neck collar. About 7 months after the first surgery, the subluxation became severe, irreducible, and assumed an atypical form where the anterior tubercle of C1 migrated to a cranial position, and the posterior tubercle of C1 and the occipital bone leaned in a caudal direction. The pathogenic process suggested deformity of the occipital condyle and bilateral C2 superior facets with atlantooccipital subluxation. A second operation for reduction and fixation was performed, and the subluxation was stabilized by posterior fixation. We encountered an unusual case of a refractory subluxation that was associated with an atypical deformity of the upper spine. The case was successfully managed by posterior fixation.

The neuorogenic tumor is known to be originated from neural crest, and the involved cells are Schwann cell, ganglion cell, and paraganglion cell. The Schwannoma, neurofibroma, and malignant schwannoma arise from the schwann cell, ganglioneuroma is from ganglion cell, and carotid body tumor and glomus tumor are originated from paraganglion cell. Authors reviewed thirty-eight patients of the neurogenic tumors in the head and neck, excluding intracranial tumor and Von-Recklinghausen disease, surgically treated at the Department of Surgery, Pusan Paik Hospital from January 1981 to May 1996. Of the 38 cases, 28 cases were schwannoma, 6 cases neurofibroma, 2 cases malignant schwannoma, and 2 cases paraganglioma. These tumors occurred at any age, but the majority of patients occurred in the fourth decade of life. There was female preponderance (M : F=1 : 1. 53) in sex ratio. The lateral cervical region was the most common distribution. 12 cases arose from the anterior triangle of neck, and 12 cases from the posterior triangle of neck. The major nerve origin of tumor could be identified in 30 cases (80%). 11 cases were treated by simple excision, and partial excision was 3 cases. Excision with parotidectomy 1 case, enucleation 11 cases, enucleation with parotidectomy 7 cases, radical neck dissection 1 cases, upper neck dissection 2 cases, suprahyoid dissection 1 case, Caldwell­Luc operation 1 case. The postoperative complications were hoarseness (2 cases), facial palsy (1 case), Homer syndrome (1 case), and hypoesthesia of tongue (1 case).

Thyroglossal duct cysts (TGDC) are the most common type of congenital developmental anomaly encountered in the anterior midline of the neck in childhood. The aim of the study was to evaluate the clinical characteristics of TGDC and identify any factors that could be related to recurrence after surgery. This study consisted of a retrospective chart review of 45 patients treated at Kyungpook National University Hospital for TGDC between 1990 and 2008. All records were reviewed for age and sex, length of history, presentation, diagnostic methods, sizes and locations of cyst, surgical management, histopathology of the lesion and recurrences. The statistical analysis of risk factors for recurrence was made using the Fisher's exact test with a significance level of p (0.05. The male to female ratio was 2.2:1 with a male preponderance. The mean age at operation was 5 years and 2 months (4 months - 17 years). The most common presenting symptom was a nontender cervical mass (78 %). Most TGDC were found in the midline position. Twenty four were infrahyold, 17 were hyoid, and 4 were suprahyoid level. Forty one (91 %) patients received the Sistrunk operation, and 4(9 %) patients received Cyst excision. Postoperative a seroma developed in six patients in the early postoperative days. There were a total of 3(6.6 %) recurrences, 2 in patients who had excision only and in one patient who had the Sistrunk operation. Univariate analysis for risk factors with recurrence showed that there was no statistical relationship between the presence of preoperative infection and the development of recurrence. The removal of hyoid bone along with TGDC was a statistically significant risk factor for recurrent disease. This study suggests that the Sistrunk operation Is the treatment of choice for TGDC in order to reduce recurrence.

This study was performed to assess the efficacy of Activator for the patient with chronic neck pain. Mail, 26 years old, is treated with Activator, which was applied for 15 minutes every two days during the 4 weeks. The results of this study are as follows: 1. The treated case compared with the previous case showed that R.O.M particularly increased in flexion and extension. 2. The atlas/skull angle compared with the previous case showed that the angle increased from $0.8^{\circ}$ to $1.5^{\circ}$. In the atlas/skull, normal angle is $5.6^{\circ}$. 3. The angle of cervical curve lordosis compared with the previous case showed that the angle increased from $38.3^{\circ}$ to $48.1^{\circ}$. In the healthy spine, the angle is $42.0^{\circ}$. 4. The anterior curvature compared with the previous case showed that curve radii decreased from 7,220mm to 200mm. In the spine, normal curvature is 165mm. 5. Rush Jackson's angle compared with the previous case showed that the angle increased from $14.8^{\circ}$ to $29.1^{\circ}$. In the healthy spine, normal angle is $39.9^{\circ}$. We can not find significant level for Activator, but it is considered that activator method of chiropractic technique is effective.

Objective : The purpose of the present study was to examine neurologic changes, fusion rate and degree of kyphosis from the surgical results of those patients who underwent multi-level anterior interbody fusion and internal fixation. Methods : Among 63 cases of the patients who received multi-level anterior interbody fusion and internal fixation in 5 years between 1995 to 1999 at the neurosurgery department, we performed a retrospective study in 52 cases that could be followed up with dynamic view imaging ; the results were compared and analyzed. The analysis was based on the results of history taking, physical findings and radiologic findings, and Odom criteria were used to classify those cases with neurologic changes. Results : Among those 52 cases in whom the follow-up was possible for at least a year and dynamic view imaging was possible, bone fusion was seen in 93% of the trauma cases and 95% in the non-trauma cases and overall bone fusion was observed in 94% of the cases. Bone fusion was seen in 93% of the autobone cases, 95% of the allobone cases, and 94% of the Mesh cases. Radiologic changes were observed by comparing the lateral view after surgery ; kyphosis was seen in 53% of the autobone cases, in 70% of the allobone cases, and in 35% of Mesh cases ; in 45% and 60% of the non-trauma cases and trauma cases, respectively ; and in 55% of the 2 level fusion cases and 46% of the 3 level fusion cases. Neurologic changes classified according to Odom criteria showed excellent result in 48% of all the cases, good in 23%, fair in 4%, and poor in 25%. Conclusion : Even those cases with multi-level fusion, a high fusion rate could be obtained by performing anterior interbody fusion and internal fixation ; those cases with kyphosis were related more with the presence or absence of posterior compartment injury rather than the fusion level ; and those trauma cases showed not much difference in the fusion rate compared with non-trauma cases but had a high possibility of kyphosis.

Objective: To analyze the prognostic factors thought to be related with survival time after a spinal metastasis operation. Methods: We retrospectively analyzed 217 patients who underwent spinal metastasis operations in our hospital from 2001 to 2009. Hematological malignancies, such as multiple myeloma and lymphoma, were excluded. The factors thought to be related with postoperative survival time were gender, age (below 55, above 56), primary tumor growth rate (slow, moderate, rapid group), spinal location (cervical, thoracic, and lumbo-sacral spine), the timing of radiation therapy (preoperative, postoperative, no radiation), operation type (decompressive laminectomy with or without posterior fixation, corpectomy with anterior fusion, corpectomy with posterior fixation), preoperative systemic condition (below 5 points, above 6 points classified by Tomita scoring), pre- and postoperative ambulatory function (ambulatory, non-ambulatory), number of spinal metastases (single, multiple), time to spinal metastasis from the primary cancer diagnosis (below 21 months, above 22 months), and postoperative complication. Results: The study cohort mean age at the time of surgery was 55.5 years. The median survival time after spinal operation and spinal metastasis diagnosis were 6.0 and 9.0 months. In univariate analysis, factors such as gender, primary tumor growth rate, preoperative systemic condition, and preoperative and postoperative ambulatory status were shown to be related to postoperative survival. In multivariate analysis, statistically significant factors were preoperative systemic condition (p=0.048) and postoperative ambulatory status (p<0.001). The other factors had no statistical significance. Conclusion: The factors predictive for postoperative survival time should be considered in the surgery of spinal metastasis patients.

Objective : Craniovertebral junction (CVJ) consists of the occipital bone that surrounds the foramen magnum, the atlas and the axis vertebrae. The mortality and morbidity is high for irreducible CVJ lesion with cervico-medullary compression. In a clinical retrospective study, the authors reviewed clinical and radiographic results of occipitocervical fusion using a various methods in 32 patients with CVJ instability. Methods : Thirty-two CVJ lesions (18 male and 14 female) were treated in our department for 12 years. Instability resulted from trauma (14 cases), rheumatoid arthritis (8 cases), assimilation of atlas (4 cases), tumor (2 cases), basilar invagination (2 cases) and miscellaneous (2 cases). Thirty-two patients were internally fixed with 7 anterior and posterior decompression with occipitocervical fusion, 15 posterior decompression and occipitocervical fusion with wire-rod, 5 C1-2 transarticular screw fixation, and 5 C1 lateral mass-C2 transpedicular screw. Outcome (mean follow-up period, 38 months) was based on clinical and radiographic review. The clinical outcome was assessed by Japanese Orthopedic Association (JOA) score. Results : Nine neurologically intact patients remained same after surgery. Among 23 patients with cervical myelopathy, clinical improvement was noted in 18 cases (78.3%). One patient died 2 months after the surgery because of pneumonia and sepsis. Fusion was achieved in 27 patients (93%) at last follow-up. No patient developed evidence of new, recurrent, or progressive instability. Conclusion : The authors conclude that early occipitocervical fusion to be recommended in case of reducible CVJ lesion and the appropriate decompression and occipitocervical fusion are recommended in case of irreducible craniovertebral junction lesion.

Background: Thyroid cancer is a relatively rare neoplasm and its incidence varies geographically and ethnically around the world. Thyroid cancer is the most common endocrine malignancy, but it has a wide spectrum of biologic behavior, histologic appearance, and management. Purpose: The purpose of the study was to analyse and evaluate all aspects of the clinical consideration in thyroid cancer. Method: Between 1986 and 1995, a retrospective analysis of 77 thyrod cancer patients admitted at the Department of Surgery, Hangang Sacred Heart Hospital, Hallym University was made to assess clinical entities. Result: By the pathological classification, the papillary carcinoma was the most common type(83.1%). Male to female ratio was 1 : 5.4 and most prevalent age group was noted from fourth decade to fifth decade(46.8%). The most common duration of illness between the appearance of the symptoms and the treatment was below 6 months(44.2%), and the most common symptom was the palpable mass at the anterior portion of the neck(96.1%). Most cases of the thyroid cancer were appeared as cold nodule in the $^{99m}$Tc-thyroid scan(95.7%). In the site of tumor location, the right and left lobe was distributed similarly. In the extent of tumor, incidence of intrathyroidal location was 41.6%, and that of the metastasis to the cervical lymph nodes was 44.2% and that of the direct capsular invasion was 27.3%, and incidence of both involved case was 13%. Surgical procedures were total thyroidectomy alone in 27 cases(35.1%) or with modified neck dissection in 6 cases(7.8%), or with radical neck dissection in 2 cases (2.6%), near total thyroidectomy alone in 22 cases(28.6%), ipsilateral lobectomy with isthmectomy alone in 12 cases(15.6%) or with modified neck dissection in 1 case(1.3%), and biopsy only in 7 cases(9.1%). The most common postoperative complications were transient hypoparathyroidism(5.2%) and transient unilateral recurrent laryngeal nerve paralysis(5.2%). Conclusion: The major problem of management of thyroid cancer include a wide spectrum of clinical behaviour of this tumor entity, the lack of reliable prognostic factors and lack of an objective assessment of the various treatment modalities. But because of showing the favorable prognosis for most thyroid cancer, appropriate and aggressive management should be recommended.

A mass appearing in the anterior or lateral side of neck often can be a diagnostic challenge. Differential diagnosis of the neck mass covers a broad spectrum of diseases and the proper evaluation and management of a neck mass requires an impressive amount of anatomic and pathologic information. Because improper diagnosis and management may convert a potentially curable malignant metastasis into incurable disease, a differential diagnosis must be considered in all patients who present with a neck mass. Authors reviewed 2,148 cases of neck mass who were diagnosed by surgical resection, biopsy or aspiration during the period between October 1982 to December 1993, excluding those with thyroid and parathyroid disease. The evaluated characteristics were age, sex, site of lesion, and pathologic diagnosis. The results were as follows: Of 2,148 cases of neck mass, the overall ratio of benign to malignant tumor was 3 : 1. In 1,603 cases of benign mass lesion, the most common disease was lymphadenitis(non-specific and tuberculosis) showing 53% incidence, the second was salivary gland tumor(13%), and the third was congenital lesion(12%). The minor problems such as lipoma and sebaceous cyst were 21 %. In the age distribution of benign lesion, tuberculous lymphadenitis showed peak incidence in second decade, non-specific lymphadenitis was main disease of childhood, salivary gland tumor was peak in fourth decade, and most of congenital lesions were diagnosed at the age below 15. In 545 malignant tumors, the most common lesion was metastatic cancer to cervical lymph nodes yielding 71 % incidence(head and neck primary 52%, infraclavicular primary 42%, unknown primary 5%), the second common disease was lymphoma(19%), and the third was salivary gland cancer(9%). In the age incidence of malignant tumor, 60% of them developed in the fifth and sixth decade, head and neck primary was more common in the fifth decade than sixth, however lymphoma showed higher incidence in sixth decade. In the analysis of mass location according to lymph node level grouping(I - V), lymphadenitis developed mostly in level V nodes, the next common occurring site was level IV in tuberculous lymphadenitis and level II in non-specific lymphadenitis. The majority of metastatic cancers were found in level IV and III, and common occurring site of lymphoma was in level II and IV. Pathologic diagnosis of neck masses were made by fine needle aspiration cytology 80 cases, incisional biopsy 533 cases, excisional surgery 1,399 cases, and neck dissection 116 cases. For the proper management of neck mass, a proper diagnostic modality should be selected from imaging techniques, cytology, biopsy or neck dissection, with the consideration of patient's age, history and clinical findings. The scapel biopsy could be used freely in the inflammatory disease or inoperable metastatic cancer, but it should be reserved in the curable metastatic cancer or clinically possible malignancy.
