Four-part displaced fractures, four-part fracture-dislocations, impression fractures of the articular surface involving greater than 50% of the head, and head-splitting fractures are to be best treated by primary prosthetic replacement. 3 primary prosthetic replacements were performed for the treatment of the proximal humeral fractures(l case of four-part displaced fracture, 2 cases of fracture-dislocation) and all cases were followe( up at least 3 years. Case II had excellent result, case I was satisfactory, and case III failure by Neers numerical ratin method. There were proximal subluxation roentgenologically in case I and III.

BACKGROUND AND OBJECTIVES: The objectives were to analyze the results of the laryngeal framework surgery (LFS) in one institute during 12 years. We reviewed the present position of LFS in the phonosurgery field and discussed the prospects for this type of surgery in the future. SUBJECTS AND METHOD: One hundred seventy nine charts of patients who underwent LFS in Yongdong Severance hospital from 1992 to 2003 were reviewed. Types of procedures were made according to the classification/ nomenclature of European Laryngological Society. RESULTS: One hundred ninty seven operations had been performed during 12 years in 179 patients. Type I thyroplasty was the most common procedure (28.9%). Type I thyroplasty+Arytenoid adduction (26.4%), Type III thyroplasty (16.8%), Arytenoid adduction (15.2%), Injection medialization (11.2%), Type IV thryroplasty (1.5%) followed in the order of most commonly operated choices. Of 197 cases, 18 cases were revision. There was only one major complication (dyspnea). A variety of dysphonias, which include vocal fold paralysis (71.5%), various pitch problems (mutational dysphonia (14%), androphonia (1.1%)), glottal insufficiency (12.8%), and some cases of spasmodic dysphonia (0.6%), had been treated with LFS. CONCLUSION: Laryngeal framework surgery is a new type of surgery that aims to improve the voice by restructuring the laryngeal framework. This type of surgery has become increasingly popular, because it has been found to be safe and effective.

17 cases of acute myocardial infarction with no or insignificant narrowing of major coronary arteries on angiogram and without any-other types of heart disease were found in a series of 133 consecutively studied patients with acute myocardial infarction(12,7%). There were no differences in risk factors between groups. Although the infarction site were similar in both groups, the patients with normal coronary arteries had fewer complications during hospitalization(p<0.05) and lesser ST segment change during the exercise test before discharge(p<0.05). In the hemodynamic fingings, cardiac index, left ventricualr and diastolic pressure and resional wall motion were similar in both groups of the patients, but ejection fraction was higher(p<0.05) in the patients with the normal coronary arteries. In conclusion, it could be predicted that the acute myocardial infarction with the normal coronary arteries would have the better prognosis. And a transient coronary occlusion, as the most likely pathogenic mechanism of the acute mtocardial infarction with normal coronary arteries, might be studied in the aspect of the thrombosis following lysis, the coronary artery spasm and the platelet aggregation.

From May, 1975 to August, 1986, we experienced 21 patients with ruptured aneurysm of the sinus of Valsalva. 1) Their ages ranged from 15 to 52 years with a mean age of 26.7 years, and 14 patients were male and 7 patients were female. Among 18 cases of which aneurysms occurred on the right sinus of Valsalva, 15 cases (83%) ruptured into the right ventricle, 1 case (6%) ruptured into the right atrium and 2 cases (11%) ruptured into the pulmonary artery. All 3 cases of which aneurysms occurred on the noncoronary sinus ruptured into the right atrium. 2) Clinical symptoms consisted of dyspnea (95%), palpitation (81%), chest pain (43%), orthopnea (33%), cough (14%), hemoptysis (5%), oliguria (5%), and fever (5%). In all patients continuous heart murmur was audible. Hepatomegaly (48%), pulmonary basal rale (14%), and pretibial pitting edema (19%) were also observed. 3) In all patients diagnosis was made with cardiac catheterization and angiography, and confirmed by operation excetpt one case. 4) Among 20 patients who had been performed corrective surgery, ventricular septal defect was observed in 16 patients (85%), aortic insufficiency in 5 patients (25%), pulmonary infundibular stenosis in 1 patient (5%), patent foramen ovale in 1 patient (5%), and tricuspid insufficiency in 1 patient (5%). Ventricular septal defect was observed in all 16 patients whose aneurysms of the right coronary sinus of Valsalva ruptured into the right ventricle and the pulmonary artery. 5) All patients survived operation, and no postoperative complication was found except 1 patient to whom reoperation was performed because of postoperative aortic insufficiency and detachment of the patch closure for ventricular septal defect. There was symptomatic improvement in all patients.

Application of membranes for guided tissue regeneration(GTR) have been confined to the subgingival barrier functions; however, many studies have provided evidence that some drugs, including tetracycline, initially can promote the growth of periodontal ligament or alveolar bone in peridontal therapy. Osseous regeneration in periodontal defects is increased by local administration of tetracycline due to its anti-collagenolytic effect, which enhances bone-forming ability via osteoblast cell chemotaxis and reduced bone resorption. The aim of this study was to evaluate effects of tetracycline loaded poly-L-lactide(PLLA) barrier membranes for guided bone regenerative potential. Tetracycline was incorporated into the PLLA membrane with the ratio 10% to PLLA by weight. Ability to guided bone regeneration of the membranes were tested by measuring new bone in the tibial defects(7x10x5 mm3) of the beagle dog for 4, 5, and 6 weeks. In control, drug-unloaded PLLA membranes were used in same size of defect. In histologic finding of the defect area, a few inflammatory cells were observed in both groups. These membrane were not perforated by connective tissue and maintained their mechanical integrity for the barrier function for 4-6 weeks. New bone formation was greater in defects covered by tetracycline-loaded membrane than in defects covered by drug- unloaded membranes. In bone regeneration guiding potential test, tetracycline-loaded membrane was more effective than drug- unloaded membranes(p<0.05). These results suggest that tetracycline-loaded PLLA membranes potentially enhance guided bone regenerative efficacy and might be a useful barrier for GTR in periodontal treatment.

From march, 1983 to May, 1987, we experienced 17 patients of Marfan syndrome. The clinical profile and course of 17 patients of Marfan syndrome were reviewed. 1) Their ages ranged from 13 to 50 years with a mean age of 30 years and 16 patients were male and 1 patient was female. 2) musculoskeletal features were present in 14(88%) of the 16 examined. Ocular features were found in 5(42%) of 12 examined. Familial features were present in 7(47%) of 15 examined. 3) Among cardiovascular manifestations dissecting aneurysm was present in 10(59%) patients, aortic annuloectasia in 15(94%), MR in 4(24%) and MVP in 1(6%). 4) Modified Bentall operation was performed to 8 patients. Two of them died. The other 8 patients took a conservative medical therapy. Four of them died.

Spasmodic dysphonia Is a form of focal dystonia affecting laryngeal muscles. There have been a few reports on the neurological aspects of the patient with spasmodic dysphonia. No data on the clinical courses and possible causative neurological diseases have been reported. We analysed 44 patients with spasmodic dysphonia, using a check-list of clinical symptoms and laboratory tests in a prospective manner, Forty one patients had adductor type of spasmodic dysphonia and three patients had abductor type. Five different clinical courses have been identified ; about half of the patients showed relentless progress of symptoms for many years(range 1-26 years ; mean 9.8 years). Magnetic resonance imaging study of the brain showed abnormalities in three patients(2 had a focal lesion in the basal ganglia and 1 had multiple cerebral infarctions). One showed acanthocytosis on electron-microscopic examination of the peripheral blood smear. Navicular tremor, low facial dyskinesla, and development of other involuntary movement at the time of onset of spasmodic dysphonia may be clues suggestive of symptomatic form of spasmodic dysphonia.
