The purpose of this study was to examine the effects of the fibrin adhesive (Beriplast$^{(R)}$) on healing of full-thickness wounds in the rat's hard palate. Twenty Spraque-Dawley strain white male rats, each weighing 250~300 gm were used. Creation of full-thickness wounds of $4{\times}4mm$ in size were performed on the hard palate. Beriplast$^{(R)}$, a wound dressing material, was applied immediately in the experimental group, but not applied in the control group. All wounds were protected with palatal resin splints. The animals were sacrificed on the 2nd, 4th, 7th, 14th, and 28th day after the operation for macroscopic and microscopic examinations. Results obtained were as follows ; 1. On the 7th day after the operation, epithelial proliferation was greater in the experimental group than that in the control group. 2. The inflammatory reaction of the experimental group was less than the control group on the 2nd and 4th day after the operation. Beriplast was resorbed on the 7th day after the operation. 3. In the control group, the epithelial proliferation occurred from the 7th to the 14th day after the operation, and in the experimental group, epithelial proliferation occurred from the 4th day after the operation. 4. On the 14th and 28th day after the operation, there was no prominent difference between the two groups in histological findings. These results suggest that the use of fibrin adhesive (Beriplast$^{(R)}$) as a palatal wound dressing results in greater epithelial proliferation and less inflammation in the early stage of wound healing.

유선열,소광섭,Ryu, Sun-Youl,So, Kwang-Sub 대한악안면성형재건외과학회 1998 Maxillofacial Plastic Reconstructive Surgery Vol.20 No.3

치조열 환자의 골이식과 관련된 치료계획 수립과 골이식재, 골이식 시기, 교정치료 시기 등 치료방법의 선택에 도움을 주는 자료로 삼고자, 1992년 1월부터 1996년 12월까지 전남대학교병원 구강악안면외과에서 골이식술을 시행한 치조열 환자중 추적검사가 가능한 31명을 대상으로 골이식술과 관련된 여러 가지 항목들과 술후 치조열부의 변연골 높이에 대하여 조사한 결과는 다음과 같다. 성별 분포는 남성(64.5%)이 여성(35.5%)보다 많았고, 남녀성비는 1.8 : 1이었다. 골이식시 연령은 이차 골이식기에 해당하는 6세에서 16세 사이(58.1%)가 많았고, 연령의 범위는 2세부터 33세까지였으며 평균연령은 11세였다. 치조열의 분류에 따른 분포는 편측성(93.5%)이 대부분이었고 그중 좌측(74.2%)이 많았다. 결손치로는 측절치가 많았고 과잉치는 측절치와 견치 사이에서 많이 관찰되었다. 술전 교합상태는 III급 부정교합 및 전치부 교차교합(65.1%)이 가장 많았고, 교정치료는 술전과 술후에 비슷하게 시행되었다. 골이식시 동시 시행한 수술로는 이차 구순수 정술이 가장 많았고, 술후 합병증으로는 골결손이 6례, 구비루가 1례, 열개가 3례 발생되었다. 골이식재로는 PMCB와 DFDB가 사용되었고 술후 변연골의 높이는 PMCB를 이식한 경우에 DFDB를 이식한 경우보다 높았으며, PMCB를 이식한 경우에는 변연골의 높이가 증가되었으나 DFDB에서는 변화가 없었다. The aim of this study was to evaluate treatment plan and treatment procedure such as bone graft material, timing of bone graft and orthodontic treatment in 31 alveolar cleft bone graft patients treated at the Department of Oral and Maxillofacial Surgery of Chonnam University Hospital from Jan. 1992 to Dec. 1996. Results obtained were as follows : In total 31 patients of alveolar bone grafts, males(64.5%) were more than females(35.5%). The patients' age ranged between 2 - 33 years of age. Secondary bone grafting was the highest incidence(58.1%) when procedures were undertaken in patients between 6 - 16 years of age. In distribution of cleft side, unilateral clefts(93.5%) were the major part with the left side was larger than the right side. The Missing teeth were found most in lateral incisor, the supernumary teeth were found most between lateral incisor and canine. The most common occlusion before operation was class III malocclusion and anterior cross-bite(65.1%), orthodontic treatment was performed similarly between before and after the bone graft. The most common combined operation with alveolar bone graft was secondary cheiloplasty. The complications were 6 cases of bone defect, a case of oronasal fistula, 3 cases of dehiscence. PMCB and DFDB were used bone graft materials. In marginal bone height after operation, PMCB grafts were higher than DFDB grafts and marginal bone level was increased in the PMCB group but not in the DFDB group.

본 교실에서는 1992년 1월 1일부터 1996년 12월 31일 까지 최근 5년간 전남대학교병원 응급실에 내원한 구강악안면외과 환자에 대한 실태조사를 시행하여 다음과 같은 결과를 얻었다. 남녀의 성비는 2.5 : 1의 비율로 남성에서 호발하였으며, 하발연령층은 20대, 30대, 9세 이하의 순이었다. 응급실에 내원한 환자의 수는 9월과 10월에 11%로 가장 많았다. 응급실에 내원한 원인으로는 교통사고, 추락사고, 구타사고 순이었다. 손상내용은 악안면열상, 악안면골절, 치아손상 순이었다. 악안면골절은 하악골 단독골절이 가장 많았으며 관골-상악골 복합골절, 하악골-상악골 복합골절 순이었으며 하악골 골절시 정중부, 과두부, 우각부 순으로 발생하였다. 저녁 6시부터 새벽 3시 사이에 응급실에 내원한 환자가 전체의 57%를 차지하였다. 주소 발생에서 응급실 내원까지는 8시간에서 12시간 사이가 가장 많았다. 이상의 결과는 구강악안면외과 영역의 응급환자가 비교적 많이 발생하고 있으므로 이를 전담할 수 있는 구강악안면외과 분양가 시급히 개설되어야 할 것임을 시사하였다. Overall study was carried out for the patients visiting Department of Oral & Maxillofacial Surgery through Emergency Room in Chonnam University Hospital, from Jan. 1, 1992 to Dec. 31, 1996. Result obtained were as follows ; Male predilection was shown, the male to female ratio being 2.5 to 1. The frequently developing age group were the first 3rd and 4th decade and under the age of 9 was followed. The number of patients for emergency was peak in September and October to 11%. About the causes for emergency, traffic accident was the most, and fall down injury and assault were followed. About the injury lists, facial laceration was preceded and the next facial bone fracture and the tooth injury followed. In the facial bone fracture, fracture in the mandible only was the most, and zygomaticomaxillary complex fracture, and mandible-maxilla complex fracture were followed. when the case of the mandible fracture, symphysis, condyle, angle were marked in succession. 57% was predomunatly ranged in the timea of 18 : 00 to 03 : 00 for the emergency. From injury onset to visiting emergency room, the range of 8 hours to 12 hours was predominant. Above results suggest that urgent patients of oral and maxillofacial area were relatively so high that division of oral and maxillofacial surgery should be established immediately.

This study was based on a series of 164 patients with zygomatic bone fracture treated at Department of Oral and Maxillofacial Surgery of Chonnam University Hospital from January 1992 to December 1996. The male-to-female ratio was 7:1. Their ages ranged from 8 to 78 years, with a median age of 35.6 years. The age frequency was highest in the second decade (30.5%), and third decade (23.8%), fifth decade (16.5%) in orders. The monthly distrbution of incidence showed October to be the month in which the greatest percentage occured (14.0%). The major cause of zygomatic bone fracture was alleged traffic accidents (53.7%). The incidence of concomitant facial bone fractures was 69,5%, and maxilla fracture (52.4%) was most frequently combined. The admission route was through emergency room (72.3%) and through outpatient department (26.8%). The incidence of associated injuries was 37.2%. The intraoral approach was the major method of treatment in zygomatic bone fracture (57.1%). The most frequent type of zygoma fracture was class IV (33.5%), and class III (25.6%) was next in order of frequency. Complications were enophthalmos (7.3%), facial asymmetry (6.7%), paresthesia (6.1%), and diplopia (2.4%) These results suggest that correct diagnosis and treatment of severity of fracture, concomitant fracture, and associated injuries are necessary, and co-operative treatment with medical department should be performed to reduce postoperative complication. 1992년 1월 1일부터 1996년 12월 31일까지 본과에 입원하여 치료받은 환자중 추적이 가능한 관골 골절 환자 164명을 대상으로 후향적, 임상통계학적으로 비교 분석하여 다음과 같은 결과를 얻었다. 관골 골절 환자의 연령 분포의 범위는 8세부터 78세까지로 평균연령은 35.6세였고, 성별 분포는 7:1로 남성에서 호발하였다. 월별로는 10월(14.0%)과 8월(11.6%)에 많았고 계절별로는 가을(31.1%), 여름(25.6%), 겨울(23.2%), 봄(20.1%)의 순이었다. 발생시각별 분포는 21~24시 (34.2%)와 1~4시 (21.3%)에 많았고, 원인별로는 교통사고(53.7%)가 가장 많은 분포를 보였다. 관골 골절의 분류에 따른 분포는 class IV(33.5%)와 class III(25.6%)가 많았고, 동반된 안면부 골절은 164명중 114명(69.5%)에서 147례가 발생하였으며, 그중 상악골 골절이 52.4%로 가장 많았다. 내원 방법은 응급실을 통해 내원한 경우가 72.3%, 외래를 통해 내원한 경우가 26.8%였으며, 타과와의 연관 손상이 있는 경우는 37.2%였다. 수상후 수술을 받을때까지 경과된 시간은 5 일 이내가 36.6%로 가장 많았으며, 접근방법으로는 구내절개법(57.1%)과 눈썹절개법(38.4%)이 많이 사용되었다. 술후 합병증으로는 안구 함몰증(7.3%), 안모 비대칭 (6.7%), 감각저하(6.1%), 복시 (2.4%) 등이 발생하였다. 이상의 결과에서 관골 골절시에는 골절의 정도와 동반 골절 및 연관 손상에 대한 정확한 진단과 치료가 필요하고 타과와의 유기적인 협조하에 적절한 처치를 해줌으로써 술후 합병증을 줄일 수 있으리라 사료된다.
