2.The cephalometric study of skeletal types in Class III malocclusion with reduced lower anterior face height.
Korean Journal of Orthodontics 1996;26(2):205-218
A given facial type can be considered as a syndrome in which various features are aggregated, so a single parameter is not sufficient to accurately identify a given facial type. This study was designed to identify & characterize the skeletal types that blend under the headline-'Cl III,deepbite'. Cephalograms of thirty-four untreated mixed dentition patients, selected mainly on the basis of clinical impression of CI III with reduced lower face heights were studied. The following conclusion can be drawn. 1. CI III malocclusion with reduced lower face height could be classified into three types. 2. Subtype 1 was identified by the following features : strong ramus, more anteriorly positioned upper molars without alveolar hypoplasia, acutely reduced Mn. plane angle. 3. Subtype 2 was characterized by a short ramus, sharply reduced postrior alveolar height, and normal Mn. plane angle. In general, this type had hypoplasia tendency in the vertical dimension. 4. In subtype 3, the AUFH occupying more percentage than ALFH was a outstanding feature. Ramal height was in normal range, alveolar hypoplasia and slightly reduced Mn. plane angle was observed. 5. The features of the subtypes were reflected in certain indices, which can be regarded as discriminative index. LAFH: if reduced, regardless of subtypes, indicates reduced lower ant. face height consistently. FHR: when this ratio is increased, it indicates subtype 1. FHl: when this ratio is in normal range, it indicates subtype 2. FPI: if reduced greatly, it indicates subtype 3.

Facial dimple creation is a simple surgical procedure. Nonetheless, several complications can occur. Actinomycosis is a rare chronic granulomatous infection caused by Actinomyces species. Some conditions that can cause actinomycosis are trauma, oral surgery, and poor dental hygiene. We report a case of actinomycosis that developed on a created facial dimple. A 51-year-old woman presented with a palpable mass on her left cheek that was approximately 1 cm in size. She had undergone facial dimple-creating surgery on both perioral areas at a local clinic 12 years previously. She had not experienced any problems until she was diagnosed with rheumatoid arthritis and diabetes mellitus about 2 years previously, for which she took leflunomide and methotrexate. The mass was completely excised through an intraoral approach. The specimen was grossly described as a gray-yellow cystic mass containing non-absorbable suture material. The filamentous nature of the Actinomyces organisms was observed in dark-stained foci on a histologic examination, confirming the diagnosis of actinomycosis. Indwelling non-absorbable suture materials may increase the risk for opportunistic infections, such as actinomycosis, in immunocompromised patients. Therefore, plastic surgeons should be aware of a patient's general hygiene, immune condition, and medical history when using these materials.

We present a case of Brown-Sequard syndrome due to a massive cervical disc herniation at C5/6 level, presenting sings of sudden and severe spinal cord compression. The lesion was diagnosed by MRI and herniated cervical disc was removed under the surgical microscope via anterior route. The result of operation was good. A brief review of the literature is given.

INTRODUCTION: Understanding the normal distribution of the tracheal diameter and crross- sectional area is one of the key elements in the management of various tracheal pathologies or tracheal reconstruction for the patients in growing age. However, data for Korean standard has been lacking. This study was designed to analyze retrospectively the distribution of tracheal diameter and cross-sectional area in young Koreans, which can afford fundamental data for the management of tracheal diseases. MATERIAL AND METHOD: Of the patients who underwent computerized tomogram of the chest between May 1996 and August 1998, one hundred six young patients(age range: 0-20 years) were included. Patients with any conditions which might affect the tracheal cross-sectional area or diameter, such as tracheal disease, previous operation, mediastinal tumor, or obstructive lung disease were excluded from the study. Gender distribution was 69 males and 37 females. Tracheal diameters, anterior-posterior and transverse, were measured at the level of the thoracic inlet(level I) and the aortic arch(level II). Types of the trachea were divided into round, oval, or horseshoe shaped on cross-sectional view, and the dimension was calculated by using the equation of A=1/4(pi)ab(A; area, (pi); 3.14, a; anterior-posterior diameter, b; transverse diameter). We analyzed the distribution of the diameter at each level and compared the cross-sectional area with respect to age and gender. A p-value lower than 0.05 wa considered significant. RESULT: The trachea of patients less than 5 years old were round in shape at both of level I and II, and no differences in cross-sectional area was observed between the levels(p=NS). As the age increased, the trachea become oval in shape at level I while it remained round in shape at level II(p=0.020). The tracheal diameter and cross-sectional area increased as the age increased with a linear correlation(r>0.9). In patients less than 5 years of age, female patients showed larger cross-sectional area than male patients (p=0.020), and it was reversed in patients older than 15 years of age(p=0.002). CONCLUSION: From the above results, we suggest chest computerized tomogram as a safe and reliable tool in measuring the tracheal diameter and cross-sectional area. We also provide the data as a standard for distribution of the tracheal diameter and cross-sectional area in young Korean population.

The authors report a case of thoracic disc herniation at T11/12 level which was downward migrated, presenting with signs of progressive spinal cord compression. The lesion was diagnosed by MRI. The operation was done by transthoracic transpleural approach using surgical microscope and the rib was not resected due to floating ribs of T11, 12. A Carbon cage with cancellous bones were used for the graft at the partial corpectomy site. The result of operation was good.

Peak expiratory flow meter(PEFM) is a portable medial device used for home health care of chronic respiratory diseases such as asthma. PEFM adapts spring principle for convenient measurement of expiratory peak flow rate, however linear scale could lead to a substantial measurement e rror. The pre sent study identified inherent er ror of the device by theore tical ana lysis, and accurately measured the error of a patented commercial PEFM. Consistent error was observed mainly due to non-linearity of the flow-to-distance conversion principle, which could be fitted to a quadratic formula with satisfactory accuracy. A simple error compensation technique was accordingly proposed based on quadratic error modeling, which decreased measurement error down to less than 1/3 of before- compensation corresponding to only an error of less than 15LPM over a wide range of flow(100-500LPM). Error compensation table was constructed for convenient use of patients. The present error compensation technique is simple and convenient not only to enhance home health care quality but also for the manufacturers to build more accurate PEFM devices.
