  • Clinical application of the cartilage formed by tissue engineering is of no practical use due to the failure of long-term structural integrity maintenance. One of the important factors for integrity maintenance is the biomaterial for a scaffold. The purpose of this study is to evaluate the difference between polylactic-co-glycolic acids (PLGA) and chitosan as scaffolds. Human auricular chondrocytes were isolated, cultured, and seeded on the scaffolds, which were implanted in the back of nude mice. Eight animals were sacrificed at 4, 8, 12, 16, and 24 weeks after implantation respectively. In gross examination and histological findings, the volume of chondrocyte-PLGA complexes was decreased rapidly. The volume of chondrocyte-chitosan complexes was well maintained with a slow decrease rate. The expression of type II collagen protein detected by immunohistochemistry and western blots became weaker with time in the chondrocyte-PLGA complexes. However, the expression in the chondrocyte-chitosan complexes was strong for the whole period. Collagen type II gene expressions using RT-PCR showed a similar pattern. In conclusion, these results suggest that chitosan is a superior scaffold in cartilage tissue engineering in terms of structural integrity maintenance. It is expected that chitosan scaffold may become one of the most useful scaffolds for cartilage tissue engineering.

  • Purpose: Tragus is one of the key structure of the normal shape of auricle. We experienced several cases of hypoplastic tragus with preauricular appendage. This article describes the methods of reconstruction of atypical tragus using accessory tragus or macrotragus to make better aesthetic results rather than simple excision. Methods: From April, 2004 to March, 2009, 21 patients got operations by our method. Seven patients had bilateral deformity of tragus. Mean age was 12.7 years. For 17 cases of accessory tragus, simple excision, z-plasty and interpolation flap was performed. For 11 cases of macrotragus, debulking and z-plasty was performed. Mean follow-up period was 9.4 months. Results: Reconstructed tragus looked symmetric with the opposite side in contour, size, direction and partial coverage of auditory meatus. There was no enlargement of remnant appendage for the follow up period and there was no complication such as hematoma, infection and chondritis. Conclusion: In cases of small and deformed tragus, preauricular tissue such as accessory tragus and macrotragus could be a good source of tragal reconstruction.

  • Background: Elastic ear cartilage is a good source of tissue for support or augmentation in plastic and reconstructive surgery. However, the amount of ear cartilage is limited and excessive use of cartilage can cause deformation of the auricular framework. This animal study investigated the potential of periosteal chondrogenesis in an ear cartilage defect model. Methods: Twelve New Zealand white rabbits were used in the present study. Four ear cartilage defects were created in both ears of each rabbit, between the central artery and marginal veins. The defects were covered with perichondrium (group 1), periosteum taken from the calvarium (group 2), or periosteum taken from the tibia (group 3). No coverage was performed in a control group (group 4). All animals were sacrificed 6 weeks later, and the ratio of neo-cartilage to defect size was measured. Results: Significant chondrogenesis occurred only in group 1 (cartilage regeneration ratio: mean±standard deviation, 0.97±0.60), whereas the cartilage regeneration ratio was substantially lower in group 2 (0.10±0.11), group 3 (0.08±0.09), and group 4 (0.08±0.14) (p= 0.004). Instead of chondrogenesis, osteogenesis was observed in the periosteal graft groups. No statistically significant differences were found in the amount of osteogenesis or chondrogenesis between groups 2 and 3. Group 4 showed fibrous tissue accumulation in the defect area. Conclusion: Periosteal grafts showed weak chondrogenic potential in an ear cartilage defect model of rabbits; instead, they exhibited osteogenesis, irrespective of their embryological origin.

  • Background: The objective structured clinical examination (OSCE) is a widely used method to assess the clinical performance of students in clinical practice. Although OSCE has been used for undergraduate students of Korean medicine, this has not been widely reported. Methods: In 2020, the practical course for acupuncture and moxibustion medicine (acupuncture, electroacupuncture, pharmacopuncture, auricular acupuncture, and burning acupuncture) was taught using flipped learning, according to clinical practice guidelines, and assessed by the OSCE. The appropriateness of this model of education and its evaluation using OSCE were evaluated using a 5-point Likert scale, and the results were analyzed. Results: Of the respondents, 67% reported that the OSCE accurately reflected their competency, and 82% reported that online video lectures helped them to improve their clinical skills. The average adequacy score of the model was > 3.7/5, and the average adequacy score of the checklist used in the OSCE was > 4.1/5 for all 5 clinical application skills. The difference in the mean self-efficacy score between students who had taken the OSCE and those students who had not taken the OSCE, was highest in the burning acupuncture group (0.923). Conclusion: This study showed that students' satisfaction with the OSCE was high and flipped learning was an effective education model. In the future, models representing the human body or simulated patients should be used to evaluate students' skills and attitude.

  • Objectives : The GB18 belongs to one of the 92 controversial points in the development of WHO standard of acupuncture point location. The number of Chon measurement of GB18 is described differently in the A-B Classic of Acupuncture and Moxibustion (ChimGuGakEulKyung; AB Classic) and the Complete Compendium of Acupuncture and Moxibustion(ChimGuDaeSeong; Complete Compendium). The aim of the study is to review the point location of GB18 and compare the relation of the location of BL7. In addition, I would like to propose new locating method of GB18. Methods : In order to review I examined the expressions of the location of GB18 and the mapping location on the acupuncture chart in the landmark classic acupuncture literatures. Results : In the most literatures, the location of GB18 was described by the distance from the GB17. The distance was 1.5 chon with one exception of 1 chon. The intervals from GB15 to GB18 was 1 chon or 1.5 chon. Although the distance from the anterior hairline is the same as 4 chon, mapping points of GB18 and BL7 on the acupuncture chart were different. Conclusions : Consequently, in the AB Classic, meaning of the location is the actual distance of scalp surface. In the Complete Compendium, however, meaning of the location is the hypothetical distance in the imaginary scalp surface. Therefore, it is safe to find the GB18 on the same level with GV20 on the connecting line of bilateral auricular apexes. The relation of GB18 and BL7 should be reconsidered.

  • Background: Cryptotia is a congenital anomaly in which the upper part of the retroauricular sulcus is absent and buried underneath the temporal skin. Various surgical techniques have been reported for the correction of cryptotia following Kubo's V-Y plasty in 1933. Conventional methods using a local skin flap, skin grafting, tissue expansion, Z-plasty, and any of these combined approaches can result in skin deficiency of the upper auricle. The aim of this study was to develop a new method that improves cosmetic results and has fewer complications. Methods: This study involved four patients in whom five cryptotia deformities were corrected using V-Y plasty and Z-plasty. After elevation of the flap, acellular dermal matrix (ADM; MegaDerm) that was over 5 mm in thickness was applied to the cephalo-auricular angle and positioned to enhance the projection of the ear. Lastly, the flap was transposed to complete the repair. Results: Between January 2014 and February 2018, cryptotia correction with ADM graft was performed in four patients. None of the patients developed a recurrence of cryptotia, and there were no postoperative complications such as wound infection, seroma formation, and dehiscence. In addition, the procedures resulted in a favorable cosmetic appearance. Conclusion: Based on these findings, i.e., no recurrence and a favorable cosmetic result, when using an ADM graft, it is suggested that this technique could be an alternative method of cryptotia correction. It could also lessen donor-site morbidity when compared to autologous cartilage grafting and be more cost-effective than using cartilage from a cadaver.

  • Objectives : The purpose of this study is to investigate treatment trends on hyperopia of chinese traditional medicine. Methods : We searched papers using CNKI and Pubmed. The keyword used on searching was 'Hyperopia' combined with 'Chinese medicine', 'Acupuncture' and 'herbal medicine'. Searching duration was not specified. The search was conducted from January 2020 to July 2021, and the final selected papers were from 1983 to 2014. Results : Studies found in CNKI were 27 and 20 sutdies were excluded. Studies found in Pubmed were 57 and 57 studies were excluded. Finally 7 sutdies were selected and analyzed. Five studies of selected ones were case reports and two were review papers. Among 5 case reports, two of them used herbal medicine with pressing auricular acupoints with beans. Another one used electronic plum acupuncture only. Another one used acupuncture with electronic heat and pulsed current stimulation. The other one compared acupuncture alone and acupuncture combined with massage. All studies report high efficacy rates on treatments. Conclusions : According to this study we found the possibility of acupuncture and herbal medicine on hyperopia. We expect that further studies will be conducted and the results of them could be actively applied to clinical treatments.
