During the past six years from July 1977 to June 1983, fifteen adult patients of patent ductus arteriosus were surgically treated. The results were as follows: 1. Of the 15 patients, their age range was 17 to 34 years with a mean of 24 years, and sexual predominance was women [9. cf. 6 men]. 2. The most common symptom showed exertional dyspnea, and 10 patients were classed in NYHA class II, the rest were all class III. 3. On physical examination, all patients were auscultated continuous murmur, but concomitantly diastolic murmur was noted apical region in 2 patients. 4. On roentgenogram of chest, normal finding was 3 patients, and the other patients were revealed the evidence of pulmonary congestion. 5. The electrocardiogram was normal in 6 patients, but LVH was seen in 5, and 2 patients were LVH+ LAH. 6. Cardiac catheterization was performed in 12, and mean value of SO2[LPA-RV] was 6.3%, Q/Q 2.09, peak systolic pulmonary arterial pressure 45.3 mmHg, and Rp/Rs 0.365. 7. All operations were carried out by posterolateral thoracotomy. In 6 patients, division and suture of ductus were possible, the other patients were treated by division and ligation with heavy silk or Dacron patch. 8. Postoperative complications were hoarseness, persistent murmur, reoperation for bleeding, and atelectasis. Early and late mortality was 20% [3 patients], and cause of death was mainly aneurysmal rupture of previous operative site.

The purpose of this study was to evaluate the amount and interrelationship of the soft and hard tissue changes after simultaneous maxillary advancement and mandibular setback surgery in skeletal Class III malocclusion. The sample consisted of 25 adult patients(13 males and 12 females) who had severe anteroposterior skeletal discrepancy. These patients had received presurgical orthodontic treatment and surgical treatment which consisted of simultaneous Le Fort I or Le Fort II osteotomy and bilateral sagittal split ramus osteotomy. The presurgical and postsurgical lateral cephalograms were evaluated. The computerized statistical analysis was carried out with SPSS/$PC^+$ program. The results were as follows. 1. The correlation of maxillary hard and soft tissue horizontal changes were high and the ratios for soft tissue to A point were $71\%$ at Sn, $67\%$ at SLS and $37\%$ at LS. 2. The correlation of mandibular hard and soft tissue horizontal changes were very high and the ratios were $84\%$ at LI, $107\%$ at ILS, $96\%$ at Pog' and $97\%$ at Gn'. 3. The correlation of mandibular hard tissue horizontal changes and soft tissue vertical changes were moderate. 4. The upper to lower lip length were increased(P<0.001). 5. The soft tissue thickness were decreased in upper lip and increased in lower lip(P<0.001). The postsurgical changes were reversely correlated with initial thickness in upper lip.

The purpose of this study is to investigate the cephalometric characteristics of the open-bite patients with DJD of TMJ. The DJD open-bite cases were compared with normal samples and Class II open-bite cases with normal TMJ respectively. Twenty three open-bite patients with bilateral DJD of TMJ($13.9\~35.3$ yens old, Group I) were selected from the Department of Orthodontics, SNUDH. Group ll consisted of thirteen Class II open-bite cases($13.2\~27.4$ years old) with no TMD signs/symtoms and good condylar shapes. Group III samples were the forty eight healthy dental students who have Class I molar relationships with no history of orthodontic treatment, good facial balance and no TMD symptoms($20.0\~26.8$ years old). First, sixty measurements in the lateral cephalometric radiographs and analysis of variance(P<0.05, Scheffe) were used to compare these three groups. The seven measurements showed significant difference(p<0.05) between Group I and Group II. After analysis of variance, six of them were used for the discriminant analysis(Wilks' stepwise analysis) and the discrminant function for Group I/Group II was obtained. The results and conclusions were as follows : In most of the measurments, Group I and Group II showed the same skeletal and dental characteristics. But seven of the sixty measurements(FH-PP angle, SNB, FH-ArGo angle, articulare angle, genial angle, upper gonial angle and Ar-Go length) were significantly different(p<0.05) between Group I and Group II. These differences may be explained by the fact that in DJD cases the mandible rotated backward due to the shortening of the ramus following the degenerative destruction of condylar head and its surrounding structures. The resulting discriminant function was : $D={-0.120X}_1+{0.066X}_2+{0.144X}_3-{0.058X}_4+2000,\;where\;X_1=ArGo\;length(mm),\;X_2=SArGo\;angle(degree),\;X_3=FH-PP\;angle(degree),\;X_4=Gonial\;angle(degree)$. Mean of the group centroids was -0.555 and percent of the 'grouped' cases correctly classified was $88.89\%$.

174 patients who visited in the Department of Dentistry, College of Medicine, Yeungnam University from 1983. 7. 15 to 1986. 11. 30 were surveyed on the tendency of patient distribution and the state of Angle's classification. The results were as follows : 1. There was increased visiting rate of patient per year. Female outnumbered male by a ratio of 1.3 : 1. 2. 8-15 age group was 74% in total visiting in the most frequency. The average visiting numbers of each month were higher among the vacation and was about 74% in that period. 3. As showed the living distribution, Nam Gu and Su Sung Gu's patients were 53% of the total. 4. As the motive of visiting in Dental Department, patients of 30% in total patients visited for themself to receive orthodontic treatment and others was introduced patients. 5. By classification, Class I malocclusion was 63% in total visiting patient, Class II malocclusion 17%, ClassIII malocclusion 20%. Crowding among Class I malocclusion was 60%.

This study was performed to investigate the factors related to vibration of temporomandibular joint during mandibular opening movement. For this study, 144 patients with temporomandibular disorders were randomly selected. Angle's classification, lateral guidance pattern, range of maximal mouth opening, preferred chewing side, and affected side were investigated clinically. Mandibular torque rotational movement during opening was recorded with $BioEGN^{(R)}$ and vibration of temporomandibular joint during opening was recorded with $Sonopak^{(R)}$. After clinical diagnosis was made, visual analogue scale(VAS) was used for evaluation of clinical progress of the subject's chief complaints. The author calculated VAS treatment index(VAS Ti) from the record of VAS. The more VAS Ti was, the less remission of subjective symptom was, The data were analyzed with SAS/Stat program and the results of this study were as follows: 1. There were no significant difference in all the variables of joint vibration by age and sex. 2. Integral and peak amplitude in patients of Angle's class I were higher than those of class II or III patients. Integral in patients of group function was higher than that in patients of canine guidance or other types of lateral excursion. 3. As to Angle's classification or lateral guidance type, there were almost not significant difference between subgroup of same class or type and subgroup of different class or type on both sides. And there were also almost not difference between one side and the other side related to preferred chewing side or affected side. 4. Patients with disk displacement with reduction showed higher value of integral and peak amplitude than any other patients. 5. Joint vibration variables significantly correlated with VAS Ti of pain. with clinical range of mouth opening, and with ingredients of mandibular torque rotational movement.

The patient, 16 years female, complained of anterior cross-bite and retrusion of maxilla. Mandibular incisors occluded labially to maxillary incisors. Normally developed mandibular arch in normal elation to facial line, S-N-Pog was within normal range. Cross-bite of anterior teeth was corrected by means of Class III elastics under multibanded system. Space for alignment of crowding of upper anterior teeth was regained by means of cervical headgear and sliding yoke. She gained good alignment of anterior teeth and attractive facial profile after 2 years.

Macroglossia can cause dentomusculoskeletal deformities, instability of orthodontic and orthognathic surgical treatment, and create masticatory, speech and airway management problems. To determine whether a reduction glossectomy is necessary, it will important to identify the signs and symptoms of macroglossia. Development of dentoskeletal changes directly related with tongue size, such as an anterior open bite or a Angle Class III malocclusion tendency, would indicate that reduction glossectomy may be beneficial. For reduction glossectomy, several techniques have been reported. However, in most techniques the tip of tongue is removed. So its excision causes the loss of most mobile and sensitive portion of the tongue, and creates ankylosed, globular tongue. To avoid such problems, central tongue reduction technique have been proposed. This article will introduce central tongue reduction for anterior openbite case associated with macroglossia.
