Correction of the Sunken Upper Eyelid Depending on the Dermatochalasis or Blepharoptosis Using the Autologous Fat Grafting

BACKGROUND: To date, many methods have been proposed to resolve the sunken eyelid. We treated our clinical cases of sunken upper eyelid based on whether there is a concurrent presence of the dermatochalasis or blepharoptosis and then performed the autologous fat grafting using either closed or open technique. METHODS: According to the classification of the patients, we used the following injection techniques: First, we solely performed the autologous fat grafting using the closed technique in the sunken upper eyelid only group, for which we did the injection using a micro-injector cannula on the suborbicularis plane. Second, we performed such procedures as skin excision, orbicularis oculi muscle strip excision and levator aponeurosis advancement to manage each symptom in the sunken upper eyelid with dermatochalasis or blepharoptosis group. Simultaneously, we also made a small window in the lateral portion of the orbital septum using the open technique with metzenbaum scissors. Thus, we performed the intraseptal injection of the autologous fat. RESULTS: During a period ranging from January of 2012 to April of 2014, we treated a total of 53 patients. The patients were followed up during a mean period of four months. Thus, we obtained satisfactory treatment outcomes without notable complications. CONCLUSIONS: In conclusion, our results indicate not only that surgeons should consider the fat grafting as one of eyelid-surgery procedures but also that they should perform it concurrently with blepharoplasty or blepharoptosis correction for the purposes of obtaining good treatment outcomes.

The Usefulnesssof Cultured Allogenic Keratinocyte for Burn Treatment

PURPOSE: When choosing dressing method to treat skin defect by second degree or higher burn, we have to consider method of rapid epithelization and minimization of pain during the treatment. In this study, we used biologic dressing with cultured allogenic keratinocytes for skin defect due to burn. We followed up the degree of epithelization, the degree of pain, and patient satisfaction. METHODS: From June 2003 to June 2006, among the patients with skin defect due to burn, 31 cases with second degree burn(moderate to severe) were selected and biological dressing with cultured allogenic keratinocytes were done. 21 cases did not use cultured allogenic keratinocytes. Most of the patients had second degree burn. We applied cultured allogenic keratinocyte by Kaloderm. For wounds that were not deep enough to effect the dermis, escharectomy was done before applying Kaloderm. After the operation, moist wound site was maintained by dressing with saline gauze for 5-7 days. We compared the condition of the wound site before and after applying Keloderm by grading epithelization by standardized percentage scoring scale(1-5), and degree of pain and patient satisfaction by visual analogue scale(0-10). RESULTS: When cultured allogenic keratinocytes were applied for the same period of time, the mean score of epithelization were 3.29+/-0.529(mean+/-S.D.). Without the application, the mean score of epithelization were 2.86+/-0.655(mean+/-S.D.). The degree of pain was 7.71+/-1.419(mean+/-S.D.) and 2.35+/-0.950(mean+/-S.D.) before and after the application, respectively. The patients' satisfaction score was 6.45+/-0.850(mean+/-S.D.) and 8.45+/-0.961(mean+/-S.D.) before and after the application, respectively. CONCLUSION: Applying biological dressing with cultured allogenic keratinocyte to skin defect due to second degree burn showed satisfactory results in the degree of the epithelization, degree of pain and patients' satisfaction.

Early Adjusting Surgery after Blepharoptosis Repair

The challenge of accurately predicting eyelid height after blepharoptosis surgery is well-known problem even in complete hands. From May, 1988 to December, 2004, authors reviewed 182 cases(240 eyes) of blepharoptosis corrected by frontalis muscle transfer or levator resection and had experienced 10 cases(15 eyelids) of early reoperation around 1 week. The period from initial operation to reoperation are between six to eight days and mean period is seven days. Initial operative procedures were frontalis muscle transfer in 3 cases(4 eyelids) and levator resection in 7 cases(11 eyelids). Follow up period ranged from 6 months to 16 years. Early adjusting surgery was performed in accordance with the preoperative and postoperative degree of ptosis of patient and considering previous operative technique. The results are evaluated according to the criteria of an ideal correction by Souther and Jordan. Seven patients have good or satisfactory results(less than 1 mm asymmetry, good in 5 cases and satisfactory in 2 cases). Three patients(5 eyelids) recorded as poor results(more than 2 mm asymmetry). Even if early or late reoperation can be effective in correcting unsatisfactory results after correction of blepharoptosis, early reoperation is better than later reoperation because early reoperation can offer a reduction in time to final result, the ease with which it is performed, potential cost savings. The experience of surgeon is also important factor for the reatment of recurred blepharoptosis.

The Operative Treatment for Carpal Boss / 대한정형외과학회잡지

PURPOSE: Carpal boss of the hand is a rare lesion. This study was conducted to recognize the clinical patterns of this disease entity and to evaluate the diagnosing modalities, differencial diagnosis, and results after operative treatment. MATERIALS AND METHODS: We report upon 7 operative cases of carpal boss of the hand. There were 5 females and 2 males with an aver-age age of 35.4. The mean follow up period for patients in this study was 15 months. The dominant hand was affected in 4 cases and the small ganglion was associated with the carpal boss in 4 cases. RESULTS: The average duration of conservative treatment before surgical treatment was 8.3 months. All of the patients had taken NSAIDs prior to surgery and 4 patients had received a corticosteroid injection at least once. All of the patient had surgical treatment and complete symptomatic relief was achieved in 6 cases. One patient had no symptomatic relief. CONCLUSION: We operated upon patients who did not respond to conservative treatment or in whom the carpal boss associated with a ganglion, 5 of 7 cases showed a satisfactory result. In view of these results, we recommended that operative treatment should be con-sidered in such cases.

Study of dopamine transporter in the rat 6-hydroxydopamine Parkinson's disease model

BACKGROUND: Neuroprotective therapy is essential in the management of Parkinson's disease(PD). As symptomatic benefit of a treatment may clinically mask the disease progression, an evaluation of the effect of a neuroprotective therapy should be based on objective measurement of in vivo dopaminergic integrity: Nuclear imaging techniques such as SPECT or PET can visualize dopaminergic system using dopamine transporter ligands and show the promise for this purpose. The objective of this study is to examine the changes of dopamine transporter in the animal model of PD and those correlations with behavioral and biochemical changes. METHODS: We injected 6-hydroxydopamine into the substantia nigra in Sprague-Dawley rats to establish the unilateral PD model, and examined the rotation response after apomorphine injection as a behavioral aspect of the animal model. And we also measured the dopamine and DOPAC level in the striata and the dopamine transporter by [3H]-mazindol autoradiography. RESULTS: We observed that the rats showed turning behavior only after severe reduction of dopamine and DOPAC. There was a strong inverse correlation between rotation behavior and striatal dopamine, DOPAC and dopamine transporter density. There was a positive and strong linear-correlation between dopamine transporter density and dopamine or DOPAC levels. CONCLUSION: Measurement of dopamine transporter gives a good estimate of striatal dopamine level in an animal model of PD. In vivo measurement of dopamine transporter will give an objective information on the integrity of presynaptic nigrostriatal dopaminergic system.
