  • 본 연구는 비만도에 따른 한국인 남성 폐쇄성수면무호흡 환자의 측모 두부 방사선계측학적 특성을 파악하기 위하여 시행되었다. 이를 위하여 계명대학교 의과대학 동산의료원 수면클리닉에 수면장애를 주소로 내원하여 수면다원검사 후 치과에서 측모 두부방사선계측사진 촬영을 한 87명의 성인 환자들을 체질량지수(BMI)와 수면무호흡지수(AHI)에 따라 비비만 단순코골이군(Non-obese, simple snorers), 비만 단순코골이군(Obese, simple snorers), 비비만 수면무호흡군(Non-obese, OSA patients), 비만 수면무호흡군(Obese, OSA patients)의 4군으로 나누어 비교하였다. 그 결과, 4군 중 비만 수면무호흡군의 수면무호흡지수가 가장 컸으며, 비만 수면무호흡군보다 비비만 수면무호흡군의 하악각이 더 크고 혀 길이는 더 작았다. 또한, 비비만 수면무호흡군보다 비만수면무호흡군의 설골이 더 전하방에 위치하였고, 수면무호흡지수에 영향을 미치는 기여 인자는 비만 수면무호흡군에서는 혀 길이, 비비만 수면무호흡군에서는 설골의 후방위치였다. 이처럼 비만 수면무호흡 환자와 비비만 수면무호흡 환자의 측모 두부방사선계측학적 특성과 기여 인자가 다르게 나타나므로, 치료방법도 따라서 다르게 선택해야 할 것이다. 비만 수면무호흡 환자들에게는 먼저 체중감량이 권고되어야 할 것이고, 비비만 수면무호흡 환자들은 폐쇄부위에 따라 구강 내 장치나 Nasal CPAP(continuous positive airway pressure), UPPP (uvulopalatopharyngoplasty) 등이 추천될 수 있을 것이다.

  • Cleft lip and/or palate is the congenital orofacial malformation most commonly occurred in humans, The disease is multifactorial and is probably caused by genetic and/or environmental factors, So, there are many problems in research concerning etiology and in treatment of the disease, Even the most practiced and sophisticated methods of surgical repair are necessarily followed by scar contraction and fibrosis, which result in skeletal defects, dental abnormalities, cosmetic disfigurement, and speech impairment, As a result, Fetal surgery can be considered but practiced rarely when the deformity is not fatal to life, And treatment of cleft palate is performed in the form of medicine projection into uterus in animal experiments, Many studies show that growth factor and its receptor emerge from the developing palate; and the epidermal growth factor receptors have a important role in craniofacial development and in palatal fusion, The palatal morphogenesis of the avine is different from the mammal's; it takes the form of physiologic cleft palate, Recently, cleft palate fusion experiment was performed when the avine were in the period of palate formation through the exogenous TGF-β3 addition, and it showed that the exogenous TGF-β3 makes fusion of divided palate through certain process when cleft palate is occurred in palatal formation, In this study, I had the conformation of the fusion of cleft palate through the addition of TGF-β in case of chicken embryo, and observed the effect of TGF-β in EGF receptor distribution, And the following is the results of this study, 1. In case of the TGF-βl and β3 addition group, there was the decrease of EGFR(Epidermal Growth Factor Receptor) immunoreactivity in mesenchymal cells beneath the medial edge epithelium and also in epithelial mesenchymal interface which is between medial edge epithelium and nasal septum in 72 hours, 2, The immunoreactivity of the control group resembles that of normal chicken embryo palate in development, 3. In the view through fluorescence confocal microscopy, there was confluence in TGF-β3 addition group, This shows that the confluence induced by exogenous TGF-β3 is related to EGFR expression in palate of chicken embryo, which is a physiologic cleft palate model.

  • Background: In recent years, pediatric chronic sinusitis patients who don't respond with antibiotics are increasing, but there are a few reports on the herbal medicine therapy treating pediatric chronic sinusitis, so this report was studied. Objective: To demonstrate the effect of herbal medicine therapy in the chronic sinusitis before and after treatment using computed tomograpy (CT) and plain radiograpy. Materials and methods: Ninty patients (45 mail and 45 femail) treated in our hospital between February 1998 and August 1999 were studied. Ages ranged from 3 to 13 years (mean age :6.5 years). Sixty two patients had a underlyiing family history (allergy or sinusitis of parents or brothers), In the past history, 68 patients had asthma, allergy of milk, atopic dermatitis, bronchiollitis and irritable bowel syndrom. Illness period was from 10 days to 96 months (mean period:12.4 month). Duration of treatment were from 25 days to 200days (mean:96 days). To ascertain the efficacy of treatment, CT in the 42 and plain radiopgrapy in the 48 patients were checked out. In the CT, three images were obtained 2cm interval on the coronal and axial plan. CT findings of the chronic sinusitis were analyzed for mucoperiostal thickening before and after treatment using 4 grades;(normal, mild, moderate, severe). Normal was defined as below 3mm thickening of mucoperiosteum; mild was 3-5mm thickening; moderate was 5mm-1cm thickening; severe was above 1cm thickening. Plain radiograpy using Water's view provided maxillary sinus, anterior ethmoid sinus, frontal sinus. Normal was defined as simillar to density between sinus and oronasal cavity; mild was defined as generally increased density with no significant mucoperiosteal thickning; moderate was partial mucosal thickening without bony hypertropy; severe was total haziness with mucoperiosteal thickening. Gamihyunggyeyungyo-tang was administered mainly. Gamigwaghyangjeungki-san, Gamizwakwi-eum and Gamihyangso-san were administered for through oral route additional symptoms Results: Of the 90 patients, 84 patients showed complete recovery (93%), 4 patients showed no significant interval change(4%) and 2 patients were aggrevated (2%). Sixty patients were severe(67%) and 26 patients were moderate (29%), 4 patients were mild(4%) The duration of treatment was varied with patient conditions (91 days in average); severe were 101.7 days, moderate were 70 days and mild were 63 days. Fifty three patients with maxillary and ethmoid sinusitis were 114 days, 35 patients with maxillary sinusitis only were 71.5 days. Fifty eight patients with both maxillary sinusitis were 94.6 days, 26 patients with either maxillary sinusitis were 65 days. The symtoms of chronic sinusitis were nasal obstruction(75%), cough(69%), purulunt or mucosal discharge(62%), lymphoid follicle(54%), postnasal dripping(49%), headache(23%) and nose bleeding(22%). Conclusion: We know that herbal medicine therapy is the effective treatment of pediatric chronic sinusitis using plain radiograpy and CT. The duration of treatment may be significant assosiation with the location and degree of chronic sinusitis.

  • Background: The two most common skin cancers are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). The purpose of this study was to describe the detailed clinical behavior of BCC and SCC in the head and neck region over 19 years at a single institution. Methods: A retrospective analysis was performed for all patients with non-melanoma skin cancer who had undergone surgical resection over an 18-year period. Patient charts were reviewed for demographic information, tumor size, onset-to-diagnosis, anatomic location, clinical subtype, histologic differentiation, method of surgical treatment, and recurrence. Results: The review identified 265 cases of either BCC or SCC in 226 patients. Of the 226 patients, 80 (35.4%) were men and 146 (64.6%) were women. BCC (n=138, 55.9%) was more frequent than SCC (109, 44.1%). The most frequent age group was 70-to-79 year olds (45 patients, 35.2%) for BCC and 80-to-89 year olds (41 patients, 41.8%) for SCC. By aesthetic units of the face, the most common location was the nasal unit (44 cases, 31.9%) for BCC and the buccal unit (23 cases, 21.1%) for SCC. The most common clinical subtype of BCC was the nodular type (80 cases, 58.0%). Local flaps were most commonly used to cover surgical defects (136 cases, 55.1%). Recurrent rates were 2.2% for BCC and 5.5% for SCC. Conclusion: In our study, many characteristics of BCC and SCC were compared to previously published reports were generally similar, except the ratio of BCC to SCC. Further study can help to establish the characteristics of BCC and SCC.

  • Prediction of the soft tissue changes following hard tissue movement is very important from the esthetic view point for patients who have orthognathic surgery. There are many cephalometric analysis of facial bone and soft tissue on the lower lip and chin region but few soft tissue analysis on the midface after mandibular setback surgery. This study was performed to obtain whether the mandibular posterior movement has influence on the midface and the predictable ratio of post-operative measurement values of the soft tissue changes following mandibular setback surgery. Fifteen patients (8 males and 7 females) who had undergone mandibular setback surgery were selected and analyzed the soft tissue movement on the upper lip and the cheek region. Post-operative changes of the soft tissue measurements after mandibular surgery were examined on pre- and post-operative cephalometrics and the ratio of changes were analyzed after drawing the reference line on the face with the barium sulfate solution. The reference lines were perpendicular to the intercanthal line from infraorbital foramen and lateral canthus. The results obtained were as follows : 1. There were tendancy of anterior movement of soft tissue adjacent the nose after mandibular surgery 2. There were incerased tendancy of the amount of anterior movement from the nasal crease to the cheek region. 3. The amount of anterior movement of the soft tissue was larger below the palatal plane compared with above the palatal plane in the cheek region. 4. The upper lip length was increased and moved posterior direction after mandibular setback surgery 5. The lower lip was moved posterior direction by posterior movement of the mandibular structure 6. Soft tissue of the midface around the nose moved anterior direction after mandibular setback surgery but there was no correlation between the amount of mandibular setback and the amount of the soft tissue changes

  • 뇌혈류 영상용 방사성의약품 Tc-99m HMPAO는 방사분해에 의해 발생하는 중간산물 때문에 화학적으로 불안정하고, 불순물 생성이 많아 표지효율 저하가 나타나기 쉽다. 과산화테크네슘(free pertechnetate)은 뇌혈류장벽을 통과하지 못하고 침샘과 구강 점막에 집적되며, 불순물이 제거되지 않으면 영상 품질이 저하되어 시각적 평가에 오류가 발생할 수 있다. 따라서 본 연구는 Tc-99m HMPAO를 이용한 뇌혈류 단일광자방출단층촬영(brain perfusion SPECT)에서 타액분비촉진제(sialogogues) 투여가 침샘 및 구강 점막에 집적된 불순물을 줄여 영상 품질 향상에 유용한지 알아보고자 하였다. 뇌혈류 단일광자방출단층촬영을 시행한 환자 중 연구에 동의한 30명을 대상으로 침샘 섭취계수(uptake coefficient)와 뇌혈류 영상을 비교 분석 하였다. 방사성의약품 Tc-99m HMPAO 555 MBq을 투여 후 기저(basal) 두 경부 전면 영상과 뇌혈류 투사상(projection view)을 획득하였다. 타액분비촉진제 구연산(citric acid)을 사용하여 침샘을 자극시킨 후 기저영상 획득 방법과 동일하게 침샘 자극 후 영상(post-citric acid image)을 얻었다. Siemens사의 영상처리 프로그램을 사용하여 좌 우 침샘부위에 관심영역을 설정한 다음 타액분비촉진제 투여 전 후 침샘 섭취계수의 평균차이를 분석(paired t-test)하였으며, 뇌혈류 영상 비교는 획득한 투사상을 반복적재구성(iterative reconstruction) 방법으로 영상을 재구성하여 비교 분석하였다. 두 경부 전면 영상의 침샘 섭취계수를 비교 분석한 결과 구연산 투여 전 섭취계수의 평균값은 $12900{\pm}3101$, 투여 후 섭취계수의 평균값은 $10677{\pm}2742$였다. 타액분비촉진제 투여 후 불순물이 많이 감소되었으며 통계적으로 유의하게 나타났다(t = 10.78, P < 0.05). 뇌혈류 영상을 비교 한 결과 침샘과 구강점막에 집적되었던 불순물이 제거되어 이미지 품질이 크게 향상되었다. 타액분비촉진제를 투여하면 침샘 및 구강 점막에 집적된 불필요한 불순물이 제거되어, 생리적 섭취에 따른 영상 품질저하를 줄일 수 있어 정확한 뇌혈류 평가에 도움이 될 것이다.
