Purpose: Various treatment methods have been utilized for recurrent dislocation of the TMJ (temporomandibular joint). The purpose of this study is to define the effect of the eminectomy with discoplasty that had been performed in patients with TMJ luxation. Materials and Methods: Twenty patients (22 joints), whose diagnosis were TMJ dislocation were selected in 772 patients (871 joints) who had been underwent TMJ surgery between 1988 and 2000. The selected patients were divided into two groups. Group I (12 joints) was the habitual-luxation group which involves the recurrent TMJ dislocation patients. Group II (10 joints) was the open lock-history group which involves the patients who had more than two episodes of TMJ luxation and TMJ disorders. The history of TMJ luxation, maximum mouth opening and other TMJ signs and symptoms before and after surgery were reviewed. Results: In group I, one patient who had been underwent both TMJ operation had a intermittent locking, but it disappeared after post-operative 32 months. In group II, intermittent pain was present in one patient who had bruxism, but it was disappeared by splint therapy. No more TMJ dislocations and other pains were checked in other patients of group I and II. Conclusion: Eminectomy with discoplasty may be used to successfully treat the TMJ habitual luxation accompanied with abnormal condition of the disc-condyle complex.

Actinomycosis is a rare form of disease that is caused by Actinomyces such as A. israelii and A. bovis, which may take the form of chronic, purulent inflammation of deep tissue evolves with necrosis, formation of sinuses and fibrotic mass. This disease arises in the head and neck area mainly in 55% and other places like that chest and the gastrointestinal tract occurs in 45%. Actinomycosis can present in a variety of forms and may mimic other infections or even neoplasms. Our case was 44-year-old man having painful indurated mass in his left TMJ area, otorrhea in his left ear and trismus. He was treated with surgical excision and biopsy confirmed actinomycosis. And after that, he was cured successfully with antibiotic therapy. We report this case of actinomycosis that developed in the left TMJ area with review articles.
Neuroblastoma treatment remains challenging, but treatment has become more effective due to the establishment of clinical and biological variables that determine prognostic risks. Initially, stage and age were the prime determinants of survival used in clinical practice. Risk-based therapy currently is the hallmark of neuroblastoma treatment. This study reviews one center's experience with the management of neuroblastoma. Sixty-three patients with neuroblastoma were treated from 1989 to 2003. All patients were graded according to the International Neuroblastoma Staging System (INSS) at diagnosis. There were 37 boys and 26 girls. The median age was 2.14 years (range, 33 days-10.2years). The primary site was the adrenal gland in 47, dumbbell shape extending into spinal canal in 6, retroperitoneum in 5, mediastinum in 3, and other sites in 2. The probability of 5-year overall survival (OS) and event free survival (EFS) were 46.7 % and 44.2 % by Kaplan-Meier method. According to INSS, there were stage 1 in 2 cases, stage 2 in 5, stage 3 in 12, stage 4 in 42, and stage 4s in 2. There were statistically significant differences in the survival rates between patients with stage1, 2 and stage 3, 4(P<0.05). For the stage 3 and 4, the extents of surgical resection, determined from the operative records and pathologies, were complete resection in 17 cases, minimal residual in 15, and partial resection 11, and the 5-year OS rate was 57.8, 51.4, and 13.6 %, respectively. There is a trend toward higher OS with more complete resection (P<0.05). We conclude that age and stage at diagnosis are prognostic factors, and complete excision of the primary tumor can provide better prognosis for patients with stage 3 and 4 neuroblastoma.
Background and Objective: The tuberculous lymphadenitis of neck is one of the most common extra-pulmonary tuberculosis in Korea. Although the incidence of pulmonary tuberculo-sis has decreased recently, that of cervical tuberculous lymphadenitis has not decreased. In spite of great efforts and diversity of study, the exact criterias of diagnosis and optimal therapeutic methods of cervical tuberculous lymphadenitis have been the subject of much debate and still remain unclear. So we intend to enucleate clinical manifestations and suggest the optimal therapeutic manners. Material : The 483 cases, diagnosed as cervical tuberculous lymphadenitis by fine needle aspiration biopsy during the past 10 years from Jan. 1987 to Dec. 1996 Method : Retrospective study Results 1) The overall rate of tuberculous cervical lymphadenitis was 23.4% of neck mass. 2) Incidence ratio of male to female was 1:2.7 3) The frequent location of tuberculous lymphadenitis was posterior cervical area, supraclavicular area, jugular chain in order. 4) The response rate of medical treatment in tuberculous cervical lymphadenitis was 84.9%. 5) The duration of medical treatment in remissioned group was 18.6 months in average. 6) Surgical intervention was needed in 15.1%. 7) The duration of post operative medical treatment was 18.4 months in average. Conclusion : Tuberculous cervical lymphadenitis is prevalent in women, age of 20-40 years and mainly involve posterior cervical area. Fine needle aspiration biopsy is a very useful method for early detection of cervical tuberculous lymphadenitis. After diagnosis is made, anti-tuberculosis medication is recommended for more than 18 months. Unless the size of neck mass is decreases inspite of the thorough anti-tuberculosis medication for more than 1 month or if complication like as abscess or fistula occurs, surgery is needed with post operative medical treatment for more than 12 months.

Purpose: Glioblastoma (GBM) carries a high propensity for in-field failure despite trimodality management. Past studies have failed to show outcome improvements with dose-escalation. Herein, we examined trends and outcomes associated with dose-escalation for GBM. Materials and Methods: The National Cancer Database was queried for GBM patients who underwent surgical resection and external-beam radiation with chemotherapy. Patients were excluded if doses were less than 59.4 Gy; dose-escalation referred to doses ≥66 Gy. Odds ratios identified predictors of dose-escalation. Univariable and multivariable Cox regressions determined potential predictors of overall survival (OS). Propensity-adjusted multivariable analysis better accounted for indication biases. Results: Of 33,991 patients, 1,223 patients received dose-escalation. Median dose in the escalation group was 70 Gy (range, 66 to 89.4 Gy). The use of dose-escalation decreased from 8% in 2004 to 2% in 2014. Predictors of escalated dose were African American race, lower comorbidity score, treatment at community centers, decreased income, and more remote treatment year. Median OS was 16.2 months and 15.8 months for the standard and dose-escalated cohorts, respectively (p = 0.35). On multivariable analysis, age >60 years, higher comorbidity score, treatment at community centers, decreased education, lower income, government insurance, Caucasian race, male gender, and more remote year of treatment predicted for worse OS. On propensity-adjusted multivariable analysis, age >60 years, distance from center >12 miles, decreased education, government insurance, and male gender predicted for worse outcome. Conclusion: Dose-escalated radiotherapy for GBM has decreased over time across the United States, in concordance with guidelines and the available evidence. Similarly, this large study did not discern survival improvements with dose-escalation.

Objective : Ossification of ligaments within spinal canal, i.e., OPLL and OLF, is uncommon clinical entity as a cause of the progressive compression myelopathy or radiculopathy. More and more cases being reported in the field of occidental medicine, but very few cases have been reported in the field of oriental medicine. The purpose of this study is to report on oriental medical approaches to OPLL and OLF. Methods : Subjects of this study are 3 cases of OPLL and 3 cases of OLF who visited Won-kwang oriental medical hospital(Dept. of acupuncture and Moxibustion) from May, 2002 to October, 2003. These patients undergo oriental medical treatment such as acupuncture, cupping, Bee-Venom therapy and herbal medication and so on. We made a comparison JOA scores between before treatment and after treatment and we evaluated results of treatment. Results : The results of treatment in these six cases are as follows ; One case was evaluated 'Excellent', one case was evaluated 'Good', two cases were evaluated 'Fair' and two cases were evaluated 'Failure'. One of these cases had a surgical operation after discharge from this hospital. Conclusions : After oriental medical care for these cases, there are some improvements such as decrease of pains, relief of myelopathy etc. But, it had little effect on some cases, therefore we considered that more special study to find various and effective methods of oriental medical treatment for these diseases should be made.

Microvascular reconstruction, in the oral and maxillofacial regions, is a widely accepted as the best way to overcome the complex oral cavity defects. Many patients requiring composite reconstructions have been treated previously with radiation therapy, chemotherapy, selective and/or functional neck dissection or any of these combinations. In many cases of these patients, inadequate neck vessels for the microanastomosis of free flap are available, due to a lack of recipient vessels in the neck, poor vessel quality or vessel caliber mismatch. To achieve a tension-free anastomosis, vein grafting must be considered to span the vessel gap between the free flap pedicle and the recipient neck vessels. Although most microsurgeons believed that interpositional grafts are to be avoided due to vessel thrombosis and increased number of necessary microanastomosis, we, authors have some confidence of equivalency between reconstruction with and without interpositional saphenous vein graft. The great saphenous vein, also known as the long saphenous vein, is the large subcutaneous superficial vein of the leg and thigh. It joins with the femoral vein in the region of femoral triangle at the saphenofemoral junction, and coursed medially to lie on the anterior surface of the thigh before entering an opening in the fascia lata, called the saphenous opening. For a better understanding of the great saphenous vein graft for the interpositional vessel graft in the oral cavity reconstructions, and an avoidance of any uneventful complications during these procedures, the related surgical anatomies with their harvesting tips are summarized in this review article in the Korean language.

Purpose: Marginal bone loss (MBL) is an important clinical issue in implant therapy. One feature that has been cited as a contributing factor to this bone loss is peri-implant mucosal thickness. Therefore, in this report, we conducted a systematic review of the literature comparing bone remodeling around implants placed in areas with thick (≥2-mm) vs. thin (<2-mm) mucosa. Methods: A PICO question was defined. Manual and electronic searches were performed of the MEDLINE/PubMed and Cochrane Oral Health Group databases. The inclusion criteria were prospective studies that documented soft tissue thickness with direct intraoperative measurements and that included at least 1 year of follow-up. When possible, a meta-analysis was performed for both the overall and subgroup analyses. Results: Thirteen papers fulfilled the inclusion criteria. A meta-analysis of 7 randomized clinical trials was conducted. Significantly less bone loss was found around implants with thick mucosa than around those with thin mucosa (difference, -0.53 mm; P<0.0001). Subgroups were analyzed regarding the apico-coronal positioning, the use of platform-matched vs. platform-switched (PS) connections, and the use of cement-retained vs. screw-retained prostheses. In these analyses, thick mucosa was found to be associated with significantly less MBL than thin mucosa (P<0.0001). Among non-matching (PS) connections and screw-retained prostheses, bone levels were not affected by mucosal thickness. Conclusions: Soft tissue thickness was found to be correlated with MBL except in cases of PS connections used on implants with thin tissues and screw-retained prostheses. Mucosal thickness did not affect implant survival or the occurrence of biological or aesthetic complications.
Purpose: In accordance to an increased interest in facial appearance and the popularization of computed tomography scanning, the number of diagnosis and treatment of blowout fractures has been increased. The purpose of this article is to review pure blowout fracture surgery through transconjunctival incision focusing on complications and their management. Methods: In this retrospective study, 583 patients, who had been treated for pure blowout fracture through transconjunctival incision from 2000 to 2009, were evaluated. Their hospital records were reviewed according to their sex, age, fracture site, preoperative presentations, time interval between trauma and surgery, and postoperative complications. Results: According to postoperative follow-up results, there were early complications that included wound dehiscence and infection (0.2%), hematoma (insomuch as extraocular movement is limited) (0.7%), lacriminal duct injury (0.5%), and periorbital nerve injury (0.7%). In addition, there were late complications that lasted more than 6 months, that included persistent diplopia (1.7%), extraocular movement limitation (0.9%), enophthalmos (1.0%), periorbital sensation abnormalities (1.0%), and entropion (0.5%). Conclusion: We propose the following guidelines for prevention of postoperative complications: layer by layer closure; bleeding control with the epinephrine gauzes, Tachocomb, and Tisseel; conjunctival incision 2 to 3 mm away from punctum; avoidance of excessive traction; performing surgical decompression and high dose corticosteroid therapy upon confirmation of nerve injury; atraumatic dissection and insertion of Medpor Barrier implant after securing a clear view of posterior ledge; using Medpor block stacking technique and BioSorb FX screw fixation; performing a complete resection of the anterior ethmoidal nerve during medial wall dissection; and making an incision 2 to 3 mm below the tarsal plate.

Background: The use of leeches can effectively increase the salvage rate of flap congestion. However, the first reaction from patients and carers in using leeches in clinical fields is strong aversion. This can be due to the fact that development of our culture from agriculture to industrial society, coming across leeches became fairly rare. Also because of the biological traits that leeches carry; staying attached to a leg or other body parts of the host, sucking blood, and leaving wounds. Methods: This study was conducted through questionnaires, divided into many subgroups. We scaled the compliance of the two therapies, with or without leech. Maximum scale of 10 showing no rejective response to the therapy and minimum scale of 0 showing the greatest rejective response. Results: Overall subjects' compliance was improved after explaining the benefits of hirudotherapy. Irrelevant to the explanation, there was no significant difference in general compliance between male and female. Young-aged group and medical personnel or people studying medicine showed higher compliance over older-aged group and the general public. Conclusion: In the terms of general social cognition, recognizing leech as a therapeutic material may not be welcomed at first, but provided with proper information and explanations, overall compliance of patients and carers can be improved and consequently result in superior outcomes in flap salvage.
