최정환,김석권,김민수,이근철,김주찬,김명훈 대한두개안면성형외과학회 2014 Archives of Craniofacial Surgery Vol.15 No.1

Background: The ear is composed of elastic cartilage as its framework, and is coveredwith a thin layer of skin. Auricular reconstruction using autogenous cartilage in microtiapatients requires delicacy. This paper reports clinical experiences related to elevation ofreconstructed ear in the last 11 years. Methods: This study was based on 68 congenital microtia patients who underwentauricular elevation in our hospital. Among these 68 patients, 47 patients were recruited. We compared the differences in the ear size, auriculocephalic angle, and conchal depthwith those in the opposite ear, and the patients’ satisfaction levels were investigatedusing a survey. Results: The difference in the sizes of the two ears was less than or equal to 5 mm in32 patients, 5 to 10 mm in 10 patients, and greater than or equal to 10 mm in 5 patients. The difference in the auriculocephalic angles of the two ears was less than or equal to10 degrees in 14 patients, 10 to 20 degrees in 26 patients, and greater than or equalto 20 degrees in 7 patients. The difference in the conchal depths of the two ears wasless than or equal to 5 mm in 24 patients, 5 to 10 mm in 19 patients, and greater thanor equal to 10 mm in 4 patients. The average grade of 3.9 points out of 5 points wasobtained by the patients with satisfactory surveys. Conclusion: We could make enough protrusion and maintain the three-dimensionalshape for a long time to satisfy our patients.

簡易方法에 依한 濟州馬의 骨瓊度別 Ca와 P의 含量測定

崔正煥,李元暢 中央醫學社 1976 中央醫學 Vol.30 No.1

The authors indeed to biometric study on the amounts of calcium and phospharus in the bone of Jeju horse in Korea. The measurement of hardness of bone were performed in 108 Jeju horse by caliper by Torybaos method. As a result of this studies, the following conclusion were obtained; (1) The correlation coefficient between grade of bone hardness and amounts of Ca and P mg per 100mm3 of bone were r=±0.972 in Jeju horse, these were statistically high significant (p<0.01) and the regression equation was y=1.795x+6.658. (2) The average of amounts of Ca and P by the undirected method were 41.58± 3.39mg/100mm3 of bone. (3) The correlation coefficient between age and amounts of Ca and P mg per 100mm3 of bone were r=+0.358(p<0.0l) and the regression equation was y=0.57x+39.85.

Smooth Auricular Cutaneous Granular Cell Tumor Mimics Epidermoid Cyst

최정환 대한청각학회 2020 Journal of Audiology & Otology Vol.24 No.2

Granular cell tumor (GCT) is a rare, benign neoplasm of Schwann cell origin. GCT is composed of cells with eosinophilic granular cytoplasm. GCT presents as a solitary painless nodule. Because of their subtle clinical presentation, GCTs are often misdiagnosed. This report of a 47-year-old woman with an auricular GCT serves to highlight that complete excision and histopathological evaluation should be attempted even in apparently benign cases, to ensure complete cure.

Umbilicated Hairy Auricular Mass Mimicking Accessory Tragus

최정환 대한청각학회 2020 Journal of Audiology & Otology Vol.24 No.2

Trichofolliculoma (TF) is a follicular hamartoma in which hairs protruding out of single orifice. To the best of my knowledge, only two auricular TF has been reported in the English literature. Moreover, clinically TF have been described to mimic malignancy. I present a case of an adult female with mass at the intertragal notch of the left auricle for several years. The clinical diagnosis was thought to be epidermoid cyst, accessory tragus, and other benign skin adnexal tumor. To prevent recurrence, the wide local excision of the mass was performed. The final diagnosis of TF was made. No recurrence was noted during the follow-up of 1 year. It is important for otologists to be familiar with the clinical and pathologic characterization of TF, to make the correct diagnosis.

고려의 중앙관제는 2성 6부인가 3성 6부인가?

최정환 한국중세사학회 2017 한국중세사연구 Vol.0 No.49

This paper is to review synthetically the results of research which have been completed until today related to the alternative theory, Two Ministries/Six Departments(二省六部) and Three Ministries/Six Departments (三省六部), and to verify that the central bureaucracy of Korea Dynasty was the very Three Ministries/Six Departments, by questioning supple- mentarily whether there was the existence of Ministery of Jungseo-Munha(中書門下省) or not. Three Ministries organized in the first year of the King Seonjong’s reign(982) were Naesa Ministry(內史省), Munha Ministery(門下省) and Eosado Ministry(御事都省). And in the fourteenth year of the same king’s reign, they were replaced by Naesa Ministry(內史省), Munha Ministery(門下省) and Sangseodo Ministry(尙書都省) after the model of the organization of China’s Tang Dynasty(唐代). Again, in the fifteenth year of the King Munjong’ reign(1061), Three Ministries got to consist of Jungseo Ministry(中書省), Munha Ministry(門下省) and Sangseo Ministry(尙書省) in imitation of the institution of Song Dynasty(宋代). Thus, Three Ministries/Six Departments of Korea Dynasty was modified according to the reality of Korea Dynasty after the model of the organization of Tang Dynasty and in reference to that of Song Dynasty as well. Eventually, Three Ministries arranged in the fifteenth year of the King Munjong’ reign(1275) got decomposed to be merged into the Upper Council(僉議府). From the above discussed, it is concluded that the central bureaucracy of Korea Dynasty was not Two Ministries/Six Departments but Three Ministries/Six Departments. My argument is that Jungseo-Munha Ministry(中書門下省) was not a unified organization but consisted of two separate Ministries, Jungseo Ministry(中書省) and Munha Ministry(門下省). Therefore, all the statements based on the false theory of Two Ministries have to be revised by all means in each book for introduction and every textbook as well.

Craniosynostosis Occurring between Siblings

최정환,김명훈,김민수,정규용,이근철,김석권,Choi, Jeong-Hwan,Kim, Myung-Hoon,Kim, Min-Su,Jung, Gyu-Yong,Lee, Keun-Cheol,Kim, Seok-Kwun Korean Cleft Palate-Craniofacial Association 2013 Archives of Craniofacial Surgery Vol.14 No.2

Craniosynostosis is a congenital anomaly in which cranial sutures close prematurely and restrict skull growth. In this paper, the case of two siblings, a male and a female, who were both diagnosed as craniosynostosis is reported. They underwent corrective osteotomy for cranial vault remodeling. A 22-month-old female infant who was brought to the department of plastic and reconstructive surgery of the authors' hospital was diagnosed with plagiocephaly. At the same time, her 7-month-old brother was diagnosed with brachycephaly. In the case of the female infant, corrective coronal osteotomy and supraorbital bar advancement were performed. Her brother underwent frontal advancement osteotomy using Tessier's tongue in the groove procedure. After the correction of the craniosynostosis, the two patients recovered in several days later, and the results were good in both cases cosmetically and functionally. They showed normal head circumference increasing curves and no symptom of functional disorder in their last follow-up. Isolated or nonsyndromic craniosynostosis is sporadic but mostly autosomal dominant. This paper presents a case of craniosynostosis with a genetic tendency; and although it occurred between siblings, the affected lesions differed. Thus, appropriate diagnosis and management in patients are needed.

흉곽출구증후군 환자에서 Current Perception Threshold (CPT) 사용경험

최정환,박종욱,최진환,성춘호 대한통증학회 2000 The Korean Journal of Pain Vol.13 No.1

Thoracic outlet syndrome (TOS) is a combination of signs and symptoms caused by the compression of the vital neurovascular structure at the thoracic outlet region. It may stem from a number of abnormalities, including degenerative or bony disorders, trauma to cervical spine, fibromuscular bands, vascular abnormalities and spasm of the anterior scalene muscle. CPT (current perception threshold) is defined as the minimum amount of current applied transcutaneously that an individual consciously perceives. It enables quantification of the hyperesthesia that precedes progressive nerve impairment, as well as hypoesthetic conditions. We experienced a case of thoracic outlet syndrome caused by fibrosis of anterior scalene muscle, The patient was a 30 years old woman with a 3 years history of numbness on the ulnar side, progressive weakness and coldness of both hand, tiredness in the left arm, nocturnal pain in the left forearm, and pain in the left elbow, shoulder and neck. Conservative treatment, stellate ganglion block, cervical epidural block, anterior scalene block and previous operation, including both carpal tunnel release, provided no remarkable relief to the patient. A left scalenectomy and first rib resection were performed by transaxillary approach and left cervical root neurolysis was done. After surgery, we measured CPT using neurometer and found conditions worsening in the opposite arm. We performed the same procedure on right side, and followed by CPT measurement. This case suggests that CPT is a useful measurement of recovery and progression of TOS.
