OBJECTIVE: To present the profiles of spinal cord tumors that can be removed through a unilateral hemilaminectomy and to demonstrate its usefulness for benign spinal cord tumors that significantly occupy the spinal canal. METHODS: From June 2004 to October 2010, 25 spinal cord tumors were approached with unilateral hemilaminectomy. We calculated the cross-sectional occupying ratio (CSOR) of tumor to spinal canal before and after the operations. RESULTS: The locations of the tumors were intradural extramedullary in 20 cases, extradural in 2, and intramedullary in 3. The levels of the tumors were lumbar in 12, thoracic 9, and cervical 4. In all cases, the tumor was removed grossly and totally without damaging spinal cord or roots. The mean height and width of the lesions we195re 17.64 mm (3-47.5) and 12.62 mm (4-32.7), respectively. The mean CSOR was 69.40% (range, 27.8-96.9%). Postoperative neurological status showed improvement in all patients except one whose neurologic deficit remained unchanged. Postoperative spinal stability was preserved during the follow-up period (mean, 21.5 months) in all cases. Tumor recurrence did not develop during the follow-up period. CONCLUSION: Unilateral hemilaminectomy combined with microsurgical technique provides sufficient space for the removal of diverse spinal cord tumors. The basic profiles of the spinal cord tumors which can be removed through the unilateral hemilaminectomy demonstrate its role for the surgery of the benign spinal cord tumors in various sizes.

The purpose of this study was to evaluate the degree of wear of periodontal curet's cutting edges made by three different manufacturers. In the first case of the experiment, this study was done with each new curett in the following three experiment. Twelve new double-ended No. 11/12 Gracy curettes from three different manufacturers (A, B and C) was randomly selected from our stock at first test. They were weared by wear tester with fixed pressure and limited distance. This study measured the width of worn curettes'cutting edge. The results were as follows; 1) In 50 times experiment, this study discoverd that each manufacturer's curette was appeared with different degree of wear (p<0.01) 2) In 100 times experiment, this study result similarly to the 50 times experiment(p<0.01). 3) In 150 times experiment, the result of this study were alike as the X50 experiment and X100 experiment. In the second case of the experiment, the study was done with a curett of a manufacturer in the following three experiment. Two double-ended No. 11/12 Gracy curette from three different manufactures (A, B and C) was randomly selected from our stock at second test. 1) In 50 times experiment, this study discovered that each manufacturer's curette was appeared with different degree of wear (p<0.05). 2) In 100 times experiment, the result was same, compared with the 50 times experiment. 3) In 150 times experiment, this study also discovered that the result was same with the result of the upper two cases. In conclusion, this study discovered that the two cases of experimental were shown with a same result.

OBJECTIVE: The intracranial pathologies after head trauma should be usually progressed. It is clearly visualized in the non-invasive brain CT. The invasive monitor such as intracranial pressure (ICP) monitoring may be accompanied with the complications. This study aims whether the patients with severe head injury could be managed with serial CT scans. METHODS: The medical records of 113 patients with severe head injury in the prospectively enrolled trauma bank were retrospectively analyzed. After the emergency care, all the patients were admitted to the intensive care unit for the aggressive medical managements. Repeat brain CT scans were routinely taken at 6 hours and 48 hours after the trauma. ICP monitoring was restrictively applied for the uncertain intracranial pressure based on the CT. The surgical intervention and the mortality rate were analyzed. RESULTS: Immediate surgical intervention after the initial CT scan was done in 47 patients. Among the initially non-surgical patients, 59 patients were managed with the serial CT scans and 7 with the ICP monitoring. Surgical interventions underwent eventually for 10 patients in the initially non-surgical patients; 1 in the ICP monitoring and 9 in the serial CT. The mortality rate was 23.7% in the serial brain CT and 28.6% in the ICP monitoring. There was no statistical difference between two groups in the aspect of mortality (p=0.33). CONCLUSION: Serial CT scans in time could be a good way to monitor the intracranial progression in the severe head injury and reduce the implantation of an invasive ICP probe.

PURPOSE: To investigate the surgical outcome of both lateral rectus resection in the treatment of residual esotropia with previous both medial rectus recession METHODS: The medical record of 30 patients who had underwent both lateral rectus resection from 1996 to 2001 for residual esotropia occurred after bilateral medial rectus recession and who had followed up for more than one year, were analysed retrospectively. Successful outcome was defined as esotropia 0.05), but it was not significant statistically. Postoperative angle of deviation in group II was increased from 8.1+/-4.6PD at postoperative 1 day to 13.8+/-7.9PD at postoperative 1 year (p<0.001). CONCLUSIONS: Both lateral rectus resection is an effective method in the treatment of residual esotropia less than 40 PD.

OBJECTIVE: To analyze the clinical data and surgical results from symptomatic chronic subdural hematoma (CSDH) patients who underwent burr-hole drainage (BHD) at the maximal thickness area and twist-drill craniostomy (TDC) at the precoronal point. METHODS: We analyzed data from 65 symptomatic CSDH patients who underwent TDC at the pre-coronal point or BHD at the maximal thickness area. For TDC, we defined the pre-coronal point to be 1 cm anterior to the coronal suture at the level of the superior temporal line. TDC was performed in patients with CSDH that extended beyond the coronal suture, as confirmed by preoperative CT scans. Medical records, radiological findings, and clinical performance were reviewed and analyzed. RESULTS: Of the 65 CSDH patients, 13/17 (76.4%) with BHD and 42/48 (87.5%) with TDC showed improved clinical performance and radiological findings after surgery. Catheter failure was seen in 1/48 (2.4%) cases of TDC. Five patients (29.4%) in the BHD group and four patients (8.33%) in the TDC group underwent reoperations due to remaining hematomas, and they improved with a second operation, BHD or TDC. CONCLUSION: Both BHD at the maximal thickness area and TDC at the pre-coronal point are safe and effective drainage methods for symptomatic CSDHs with reasonable indications.

PURPOSE: Since the laparoscopic cholecystectomy became an usual procedure, operative indications of the gallbladder polyps have had the tendency to enlarge. There are no precise management plan about the gallbladder polyps which is not included in the accepted operative indications. Therefore a management plan may be required for the patients who has gallbladder polyps which is not accepted operative indications. METHODS: We retrospectively analysed 106 patients with gallbladder polyps who were diagnosed preoperatively by ultrasound and CT from January 1991 to January 2005. Our operation indications are polyp above 10 mm, symptomatic polyp, sessile polyp, coincidence of stone, focal thickening of gallbladder wall, diffuse wall thickening and detection during other operations. The gallbladder polyps which were suspected to the gallbladder cancer strongly on radiologic studies and polyps above 20 mm size were excluded in this studies. RESULTS: Among the 106 patients, 87 patients underwent operation, and polypoid lesions disappeared during the follow-up period in 3 patients, and 16 patients are on regular follow up. Fifty-six cases received operation with accepted operative indications, and the thirty-one cases underwent operation by the patient's demand. Two groups showed significant difference in true polyp on pathological diagnosis (P < 0.001). There was 16.07% true polyp in opertive indication based 56 patients and no true polyp in patient's demanded 31 cases. The pathologic diagnoses were cholesterol polyp in 27 patients (87.15%), no polyp in 2 patients, adenomatous hyperplasia in 2 patients. The correlation of the polyp size and pathologic diagnosis was an inverse relation to the polyp size and incidence of pseudopolyp (P=0.014). CONCLUSION: We propose that the 6-month-interval follow-up observation is fully safe for polyps sized below 10 mm and not included in accepted operative indications.

PURPOSE: To investigate the surgical outcome of unilateral lateral rectus recesssion in the treatment of intermittent exotropia under 25 prism diopter (PD). METHODS: The 62 patients who had underwent unilateral lateral rectus recession and followed up for 6 months or larger, were reviewed. Following inferotemporal fornix incision, 8.5 mm or 9.5 mm recession from the insertion of lateral rectus was performed in 20 PD or in 25 PD intermittent exotropia respectively. RESULTS: Mean age of patients was 8.8 years (5-14 years) and follow up time was 11.5 months (6-34 months) on average. Postoperative deviation and success rate were as followings: -0.2+/-2.1 PD, 91.9% at postoperative 1 day, 0.5+/-2.3 PD, 95.2% at postoperative 1 week, 2.5+/-3.9 PD, 96.8% at postoperative 1 month, 3.7+/-5.0 PD, 91.9% at postoperative 6 month and 4.3+/-5.5 PD, 85.7% at postoperative 1 year. The average divergent shift was 4.5 PD during whole examination period and this shift showed significant change during same period (Repeated measures, p=0.000). The occurrence rate of undercorrection was 1.6% at postoperative 1 week, 3.2% at postoperative 1 month, 8.1% at postoperative 6 month and 14.3% at postoperative 1 year. The occurrence rate of overcorrection was 8.1% at postoperative 1 day and 3.2% at postoperative 1 week. All cases of overcorrection were orthophoric after postoperative 1 month. The limitation of abduction was not discovered in all cases at postoperative 1 year. CONCLUSIONS: Unilateral recession of lateral rectus is an effective method in the treatment of intermittent exotropia under 25 PD. However long term follow up should be considered since undercorrection seems to be increasing.
