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 evaluate the effect of reverse geometry lens (RGL) on correction of moderate degree myopia and cornea in patients of moderate-degree myopia. METHODS: 48 eyes of 82 eyes were chosen to wear reverse geometry lens and the remaining 34 eyes were fitted with rigid gas permeable (RGP) lens. The subjects were tested three days, one, two weeks, one, two and three months after fitting the lens. Uncorrected visual acuity, manifested refractive error, corneal thickness and corneal endothelial cell count were evaluated. corneal topography were performed. RESULTS: The uncorrected visual acuity was increased at 0.05 LogMAR after two weeks. and manifested refractive error decreased during the first months, thereafter stabilizing to -0.2 D (diopters). Corneal thickness was 540.4 micrometer and 583.0 micrometer in the center and mid-periphery, decreased to 505.2 micrometer and 572.7 micrometer, respectively, three months after RGL fitting (p<0.05). Endothelial cell count was 2663.5 cells/mm2 and 2541.5 cells/mm2 in the center and mid-periphery, 3 months after RGL fitting and endothelial cell count was not significantly different compared with that of pre-fitting. There was no statistical difference between RGL fitting group and RGP fitting group in the change of corneal endothelial cell count. CONCLUSIONS: RGL was found to be effective in correction of moderate-degree myopia. It had minimal effect on corneal endothelium, in short-term usage, however, the change of corneal thickness suggests that RGL fitting may effect on corneal epithelium and stroma.

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.

PURPOSE: To find the factor that affects the long-term intraocular pressure after glaucoma implant surgery with releasable suture. METHODS: We retrospectively reviewed the medical records of the 33 patients (36 eyes) who had undergone glaucoma implant surgery with our own expanded-Polytetrafluoroethylene (e-PTFE) membrane-tube implant with temporary closure of the tube by releasable suture. Data such as timing of suture release, IOP's before and after surgery and the amount of pressure change during follow-up were collected, and we tried to find the factor that influenced the IOP at the last visit. RESULTS: The preoperative IOP was 43.2+/-14.6 mmHg and the suture was released at day 17.9+/-9.5 after surgery. The IOP just before the release of suture was 33.5+/-17.1 mmHg. The pressure was dropped to 15.1+/-13.7 mmHg, measured at 30 minutes after the release of the suture. The IOP was stabilized to 14.9 +/-9.5 mmHg at 12.2+/-7.0 days after the release. The average follow-up was 32.8+/-26.3 months and the IOP at the last visit was 17.3+/-10.5 mmHg. Four eyes (11%) had hypotony (IOP less than 8 mmHg) before release of the suture, thirteen eyes (41%) showed hypotony 30minutes after release, and three eyes(8%) showed hypotony at the last visit. Multiple linear regression analysis revealed that the IOP at 30 minutes after release of the suture had a positive correlation with the IOP at the last visit (r=0.642,p=0.000). CONCLUSIONS: In the membrane-tube implant surgery for the refractory glaucoma, the releasable suture echnique is helpful to prevent the early postoperative hypotony. By measuring early post-release IOP after implant surgery with releasable suture technique, we might predict the behavior of long term IOP change; the lower post-release IOP, the better long-term pressure control.

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.

PURPOSE: Unilateral breast reconstruction after mastectomy confront the challenges of recreating a natural appearing breast mound and achieving symmetricalness of the breasts. If the patient's remaining breast is large compared to reconstructed breast, the most common procedure is reduction mammoplasty of the large breast side. The authors experienced a new method of breast reconstruction using the excess breast tissue from the contralateral breast after breast reduction. METHODS: The excess tissue from the contralateral breast after vertical reduction mammoplasty with superior pedicle and remaining lower breast tissue were transferred to the mastectomy site breast through the subcutaneous tunnel on the chest wall. The main blood supplies of the flap are perforator branches of the 4th, 5th and 6th anterior intercostal artery. After elevating and detaching the flap on the lower lateral area of the breast, the turned over flap is fixed on the upper portion of the chest wall of the mastectomy site. RESULTS: On two cases of the breast reconstructions, remaining excess breast tissue from reduction mammoplasty was transferred to the contralateral breast side as pedicles. Both patient and operator were satisfied with the outcome of the reconstruction as the breasts were symmetrical and in natural shape. CONCLUSION: We have performed unilateral breast reconstruction using the excess breast tissue after reduction mammoplasty of the contralateral breast. As Oriental women's breasts are relatively smaller than those of Caucasian women, delayed breast reconstruction cases of Oriental women with large breasts(macromastia) seem to be ideal for this procedure.
