PURPOSE: To evaluate the effectiveness of intreaepithelial photorefractive keratectomy (IE-PRK) for the treatment of myopic regression after laser in situ keratomileusis (LASIK) METHODS: 38 eyes of 22 patients who had previous LASIK for myopia were selected and retreated with IE-PRK, in which a photoablation was performed directly in the epithelium without damage to Bowman's layer. All eyes were elapsed at least 6 months after the LASIK. Follow-up was up to 6 months and within +/-0.50 of emmetropia on 6 months after surgery was considered as a success. RESULTS: Before IE-PRK, the eyes regressed to a mean of .1.26+/-0.45 D spherical equivalent (SE). The mean SE at 1 week after IE-PRK was .0.44+/-0.88 D, 1 month was .0.59+/-0.45 D, 3 month was .0.63+/-0.41, 6 month was .0.62+/-0.43 (p<0.05). 23 of the 38 eyes (60.5%) had refraction within +/-0.50 and were considered as successfully treated. Preoperative mean best corrected visual acuity (BCVA) was 0.33+/-0.18 (Snellen equivalent) and final mean BCVA was 0.77+/-0.99 (p<0.01). There were no significant complications of corneal flap. CONCLUSIONS: The results of this study indicate that intraepithelial photorefractive keratectomy appears to be a safe means for treating patients for regression after LASIK procedure. But success rate was not so good as the enhancement. Controlled studies with larger population will be necessary to evaluate the accuracy of the method more correctly.

PURPOSE: To compare results of laser in situ keratomileusis (LASIK) and laser epithelial keratomileusis (LASEK) for the treatment of high myopia. METHODS: In this study, 129 patients with a manifest refraction over -6.00 diopters were assigned two groups for 144 eyes of 72 patient treated with LASIK and 114 eyes of 57 patients treated with LASEK. Uncorrected visual acuity, manifest refraction, corneal haze and other complications were reviewed in LASIK- and LASEK-treated eyes at 6 months after the operation. RESULTS: At the 6-month follow-up, there were significant between-eye differences in uncorrected visual acuity and mean spherical equivalent. And LASEK-treated eyes had more corneal opacity and it makes decreased uncorrected visual acuity. CONCLUSIONS: Both laser refractive surgeries were safe and effective methods to treat eyes with high myopia. But LASIK procedure may prove superior to decrease corneal opacity and visual predictability.

The extracorporeal respiratory support has (ECMO) or extracorporeal lung assist (ECLA). Jugulocarotid(JC) ECLA, which drains venous blood via the internal jugular vein and perfuses via the common carotid artery, is recognized as a therapeutic modality for acute respiratory failure of neonates. But recent follow-up studies report the possible neurologic complications after the ligation of the carotid artery. Femoro-femoral (FF) bypass is reported to be effective in cardiac support during cardiopulmonary resuscitation. Surgical approach of FF bypass is easier because of the superficial location of great vessels. To evaluate the cardiorespiratory support of FF bypass, twelve mongrel dogs were divided into JC and FF groups(n6 in each group) and ventilated artificially at F1O2 of 0.3 and 0.15 in a dog. While ventilating the oxygenator with N2 gas, control hemodynamic and blood gas values were obtained at FO1O2 0.3 and at F1O2 0.15. The values during VA ECLA in both groups were measured while flushing O2 gas into the oxygenator. We compared bypass flows and oxygenation effects between two groups. l) The comparison between JC ECLA and FF ECLA in F1O2 0.3 Mean arterial pressure (MAP) and cardiac output (CO) increased in both groups and mean pulmonary arterial pressure (MPAP) decreased in JC group. Bypass flow rates were 86+/-6ml/kg/min in JC group and 62+/-8 ml/kg/min in FF group. 2) The comparison between JC ECLA and FF ECLA in FO 0.15 MAP and CO increased in both groups and MPAP decreased in JC group. VA ECLA increased the arterial oxygen tension from 49+/-12 mmHg to 93+/-20 mmHg in JC group and from 54+/-14 mmHg to 77+/-12 mmHg in FF group. Bypass flow rates were 103+/-21 ml/kg/min in JC group and 67+/-12 ml/kg/min in FF group. The amount of changes of deltaPaO2(y) related to bypass ratio(x) was same between two groups The systemic oxygenation effect of FF ECLA in hypoxia was as efficient as that of JC ECLA. In conclusion, FF ECLA can be adopted for acute respiratory failure in which PaO2 is maintained about 50mmHg.

PURPOSE: Even though Augmentation rhinoplasty is very popular surgical procedure, it is not easy to obtain ideal materials for augmentation. Many different synthetic materials are used but frequent complications are seen such as infection, extrusion, deform, and dislocation. Autologous tissues were used for augmentation rhinoplasty. We used dermofat graft and fat injection in augmentation rhinoplasty minimizing these problems. METHODS: From 2006 to 2009, we used autologous tissues in augmentation rhinoplasty in 40 patients, 20 patients with dermofat graft and other 20 patients were treated with fat injection only. Dermofats were harvested from sacral area. gluteal fold, groin and preexisting scar tissue. Dermofats were inserted with small stab wound and fat tissues were injected as Coleman's technique. The patients were followed up 6 months to 5 years. RESULTS: Most of the patients were satisfied in shape and height the nose. Early complications such as hematoma, infection and seroma were not found. Secondary fat injection was performed in 3 patients (15%) of dermofat graft group instead of 7 patients (35%) of fat injection only group. CONCLUSION: We obtained satisfactory results in augmentation rhinoplasty with dermofat graft and fat injection. Secondary fat injections were more often in fat injection group than dermofat graft group. Dermofat graft and fat injection could be another alternative technique for augmentation rhinoplasty and fat injection could be a secondary adjunctive treatment for undercorrection due to absorption.

Craniopharyngiomas are usually considered to arise from the pituitary stalk and upper aspect of the pituitary gland. However, they very rarely develop from the floor of the third ventricle or the lamina terminalis, and are intrinsically confined to the third ventricle ; about 40 cases have been reported in the literatures. We have recently experienced a case of intrinsic intraventricular craniopharyngioma with the density a little higher than cerebrospinal fluid on the brain CT.

Defects in the dura mater can be result from craniocerebral trauma, neoplastic or inflammatory destruction surgical removal and congenital absence. Materials used for closure of dural defects were variable. Of these, autogenous fascia lata have been used for a long time. It seems interesting to study the histologic fate of the autogenous grafted fascia lata in the dural defects. After autogenous fascia lata graft to dural defect in 18 rabbits, the histologic fate of the autogenous grafted fascia lata was observed microscopically. The results are as follows: 1) The adhesions among the grafted fascia lata, arachnoid, pia mater and brain cortex were usually mild. This result may be due to either short period of observation or autogenous substitutional material. 2) The grafted autogenous fascia lata was revealed minimal inflammatory response and was ultimately reabsorbed. 3) The grafted autogenous fascia lata was replaced by granulation tissue and fibroblast originated from the host mesenchymal tissue.
