As the use computed tomographic (CT) scanning spread, the diagnosis of blowout fractures of the medial orbital wall increased. Now, the diagnosis of blowout fracture in the medial wall are not uncommon. Conventionally, the surgery of blowout fractures in medial orbital wall was performed by the various approach with external incision. The conventional method had seveal possible disadvantages, including an external scar, incomplete reduction, increased mobidity rate and general anesthesia. Recently, endoscopic reconstruction of the medial orbital wall has provided good functional and cosmetic results. We performed endoscopic transnasal reduction surgery without external incision in 12 cases of medial blowout fracture under local anesthesia. The fractured bony fragments were removed after the intranasal ethmoidectomy and the entrapped medial rectus was released. And then a sheet of silicone late or uncinate process were placed on the fracture site. For the maintain of the position of fractured wall, Merocel packing or urinary ballon catheter were used in orbital fracture site for 1-3 weeks. There were no specific complications related to this procedure. Result of the surgery in all cases were satisfactory. In this article, we discussed the surgical procedure, the benifit of the transnasal endoscopic approach, the indications for surgery, and possible comlications.

Intravascular lymphomatosis (IL) is a variant of non-Hodgkin's lymphoma with an predilection for the CNS. Most cases are not diagnosed until postmortem. IL is characterized by neoplastic proliferation of lymphoid cells within the lumen of small veins and arteries with minimal involvement of the parenchyma. We experienced a 62-year-old woman who presented with seizure and fever associated with anemia, elevated LDH and beta 2-microglobulin without systemic involvement. This report illustrates the diagnostic challenge of this rare disorder with a grave prognosis. (J Korean Neurol Assoc 19(4):413~416, 2001)

STATEMETN OF PROBLEM: Surface alteration of the implant screws after function may be asso-ciated with mechanical failure. Theses metal fatigue appears to be the most common cause of structural failure. PURPOSE: The purpose of this study was to evaluate surface alteration of the implant screws after function through the examination of used and unused implant screws in SEM(scanningelectron microscope). MATERIAL AND METHODS: In this study, abutment screws(Steri-oss, 3i), gold retaining screw(3i) and titanium retaining screw(3i) were retrieved from patients. New, unused abutment and retain-ing screws were prepared for control group. Each of the old, used screws was retrieved with a screwdriver. And retrieved implant complex of Steri-oss system was prepared for this study. Then, SEM investigation and EDS analysis of abutment and retaining screws were per-formed. And SEM investigation of cross-sectioned sample of retrieved implant complex was performed. RESULTS: In the case of new, unused implant screws, as maunfactured circumferential grooves are regularly examined and screw thread are sharply remained. Before ultrasonic cleans-ing of old, used implant screw, a lot of accumulation and corrosion products were existed. After ultrasonic cleansing of old, used implant screws, circumferential grooves as examined before function were randomly deepened and scratches increased. Also, dull screw thread was examined. More surface alterations after function were examined in titanium screw than gold screw. And more surface alteration was examined when retrieved with driver than retrieved without driver. CONCLUSIONS: These surface alteration after function may result in the screw instability. Regularly cleansing and exchange of screws was recommended. We recommend the use of gold screw rather than titanium screw, and careful manipulation of the driver.

The authors analyzed 52 patients with traumatic cervical fracture and dislocation admitted to the department of neurosurgery, Gyeongsang National University Hospital between July, 1989 and December, 1993. The most common age group was 21-30 years old, and 46 were male. The most frequent cause of injury was motor vehicle accident. High cervical injuries were 11 cases and mid-low cervical injuries were 41 cases. 34 cases had surgical intervention by anterior approach with bone graft only(5), anterior approach with bone graft and instrumentation(9), posterior approach with wiring and bone graft(18) and total laminectomy(2). The others had conservative treatment and immobilized by traction(9), Halo-vest(8) or neck collar(1). The average post of immobilization of conservatively treated patients was 9.7weeks, anterior approach without instrumentation was 9 weeks and posterior approach was 5.4 weeks, but patients who treated by anterior approach with instrumentation keep soft collar only. At final follow-up, no significant differences were noted between surgically and conservatively treated group but initial neurologic state correlates with prognosis, independent of modality of treatment. Thus the surgical intervention does not significantly influence the prognosis of the patient but shortens the duration of postoperative immobilization.

Benign tumors of the esophagus occur rarely as compared with the incidence of carcinomas. Among the benign tumors of the esophagus such as leiomyoma, lipoma, hemangioma, papilioma. polyp, cystetc. leiomyoma is the most common, although less than 10 percents of leiomyomas of the gastrointestinal tract are found in the esophagus. Most of leiomyomas of the esophagus present as solitary lesions but multiple tumors occur in about 4 percents of cases. Leiomyomas of the esophagus are diagnosed by thorough clinical evaluation, esophagogram and upper gastrofiberscopic examination but histological confirmation requires surgical or necropsy specimens. Occasionally gastrofiberscopic polypectomized specimens are used. We report one case of multiple leiomyomas of the esophagus located in between 25 cm and 40 cm distance from the incisor in a 38-year-old man who complained of vague substernal discomfort for about 10 years. Gastrofiberscopic polypectomized specimen was used for preoperative histological confirmation. The pathologic examination of the specimen showed leiomyoma of the esophagus.

BACKGROUND AND OBJECTIVES : Ageotrophic nystagmus in the horizontal canal BPPV has been explained as a result of cupulolithiasis theory, and has been reported to have the less therapeutic response to conservative rehabilitations than the other type BPPV . Though methods to detach the debris with vibrator have been introduced, the effect has been questioned and it's not physiologic. MATERIALS AND METHOD : We introduce a new head shaking-forced prolonged position method as a more convenient method, and report typical 2 cases of ageotrophic horizontal canal BPPV managed with it and analyzed results of 25 cases all told. RESULTS AND CONCLUSION : The average number of rehabilitation was less than two, and loss of direction changing positional nystagmus could be observed immediately after rehabilitation.
