Complications after a median sternotomy incision, which is used currently in most open heart surgery, are serious, although it is infrequent. Reconstruction of the sternal defect resulting from dehiscence of median sternotomy is still big challenge to the most plastic surgeons. Since vascularized greater omentum was transposed to eliminate mediastinal wound problems, many vascularized regional muscle flaps became mainstay in reconstruction of median sternotomy wound. We treated 13 patients with median sternotomy dehiscence between October of 1993 and March of 1998. In two patients, the wound problems were so confined to superficial tissue that debrided and closed primarily. Eleven patients with deep wound infection were managed with vigorous debridement of all necrotic tissues and resultant defects were covered with regional muscle flaps: rectus myocutaneous flap(3) and bilateral pectoralis advancement flap(8). We used the pectoralis major advancement flaps without counter incision at humeral insertion site and the dissections were limited only medial to the anterior axillary line to preserve the axillary fold. In five patients with larger defects, we elevated muscle and cutaneous flaps separately to make these flaps more mobile. Large portion of two rectus abdominis flaps could not survive, whereas pectoralis advancement flaps had mo special wound problems. Only one patient developed fistula due to remained wire, regardless to flap surgery.

BACKGROUND: In patients with myocardial infarction, one needs to know the location, extent and severity of wall motion abnormalities to assess prognosis and guide therapy. Thus more precise quantatative estimates of regional ventricular function are required. Regional wall motion has generally been assessed by displaying the multiple cardiac images of RVG as endless-loop movie, but the cinematic display was not objective. We used the usefulness of the phase analysis in evaluating the global left ventricular function and regional wall motion abnormalities of patients with myocardial infarction. The accuracy of the RVG cinematic display in detecting regional wall motion abnormalities in patients with myocardial infarction was also evaluated. METHODS: Studied cases were 97 patients with myocardial infarction and 20 normals with low likelihood of coronary artery disease. Coronary angiography and contrast left ventriculography were performed in all patients with myocardial infarction. The regional wall myocardial infarction(presence) is defined when the EKG presented the evidence of myocardial infarction, left ventriculogram showed RWMA(regional wall motion abnormality) along with stenosis of 50% or greater of the regional supplying coronary artery. Each patient was imaged in 45 left anterior oblique(LAO) view, anterior(Ant) view and left lateral(Lt Lat) view. We evaluated Left ventricular ejection fraction(LVEF) from time-activity curve. We constructed the histogram for the left ventricle and both ventricle separately to obtain the global and total phase angle(GPA, TPA), standard deviation of phase angle(GSDPh, TSDPh), full width half maximum(GFWHM, TFWHM). The left ventricle was divided into 7 segments. LAO projection ; septal, apical, basal lateral, apical lateral, Ant projection ; anterolateral, Lt Lat projection ; inferior, posterior, Phase angle(RPA) and full width half maximum(RFWHM) from the histogram (regional 7 segments) were examined. On the RVG cinematic display, the standard 4 grading system was used, normal, hypokinesia, akinesia, dyskinesia. The observer evaluated regional wall motion abnormality of the 7 segments for all cases. The sensitivity of the above parameters and RVG cinematic display was evaluated. We analyzed the regional parameters among the patents with regional wall myocardial infarction(presence), those without regional wall myocardial infarction(absence) and control group using the t-test. The statistical analysis was done by one way ANOVA between regional phase analysis and RVG cinematic display. RESULTS: The sensitivity of LVEF was lowest(70.1%) and the GFWHM was highest among the global parameters(89.1%). But RFWHM showed even higher sensitivity(96.9%), thus regional phase analysis was also required. The RVG cinematic display was also sensitive(92.7%), but less sensitive than the RFWHM. On regional phase analysis the RPA of septal, apical, inferior, posterior walls of the left ventricle was able to separate presence group from absence group and also presence group from control group and the RPA of the apical lateral wall could separate presence group from absence group. The RPA of basal lateral and anterolateral wall was inaccurate in diagnosing the regional wall myocardial infarction, because basal lateral wall was overlapped by adjacent vascular structures, and the area of anterolateral wall dose not correlate completely beteen the RVG & the left ventriculogram, also the anterolateral wall can be supplied by the obtuse marginal branch of left circumflex artery. The RFWHM of all regional walls of left ventricle could separate presence group from absence group and presence group from control group. We found good correlation between regional phase analysis & left ventriculogram for detection of regional wall myocardial infartion. On RVG cinematic display, the RPA of the normal group was different from that of dyskinesia, akinesia and hypokinesia groups. The RPA of the dyskinesia group was also different from that of skinesia and hypokinesia groups by oneway ANOVA(p<0.05). The RFWHM of the dskinesia group was different from that of the normal group and hypokinesia group. RVG cinematic display correlated well with regional phase analysis and also quantitation of wall motion. CONCLUSIONS: Thus RVG cinematic display was useful and can not be replaced by phase analysis. But the regional phase analysis was sensitive and objective in diagnosing the wall motion abnormality in myocardial infarction.

Split hand split foot(SHSF) is a rare human developmental defect characterized by mi-ssing digits, fusion of remaining digits, and a deep median cleft in the hands and feet. Cy-togenetic studies of deletions and translocations associated with this disorder have indicated that an autosomal dominant split hand/split foot locus maps to 7q21-q22. We have experienced a case of ectrodactyly in a 25-year-old primigravida woman and her baby and reported out our experience with a review of related literature.

This is a case report of correction of malunioned maxilla after traffic accident by Le Fort I osteotomy and posterior segmental osteotomy. By this procedure, authors obtained the following results. 1. The malunioned maxilla after traffic accident which had anterior crossbite, posterior open bite and scissor's bite were corrected by Le Fort 1 osteotomy and posterior segmental osteotomy. 2. No postoperative infection and specific complication were seen in this case. 3. Postoperative intermaxillary fixation was maintained for 8 weeks. And then, the patient could open his mouth in normal range after a week of intermaxillary fixation removal. 4. For rigid fixation and reducing relapse, the osteotomized maxilla was fixed with miniplates.

It is. commonly assumed that nasorespiratory function can exert a dramatic effect upon the development of the dentofacial complex. Specially, it has been stated that chronic nasal obstruction leads to mouth breathing, which causes altered tongue and mandibular positions. If this occurs during a period of active growth, :the .outcome is development of the "adenoid facies". Such patients characteristically: manifest a vertically long lower third facial height, narrow alar bases, lip incompetence, a long and narrow maxillary arch and a greater than normal mandibular plane angle. But several authors have reported that so-called adenoid facies is not always associated with adenoids and mouth breathing, and that a particular type of dentition is not alwarys found in mouth breathers with or without adenoids. Some authors have believed adenoids lead to mouth breathing in cases with particular facial characteristics and types of dentition. We assumed that the ability to adapt to individual's neuromuscular complex is various. So, we compared the difference of influence of mouth breathing between childrens who have different facial types. This study included 60 patients and they were divided into three groups by Rickett's facial type. Their dentition and tongue position were compared. The results are as follows. 1. There is a significant difference in arch width of upper molars between different facial types. Especially dolichofacial type patients have narrowest arch width. 2. There is a significant difference in tongue position between different facial types. Especially dolichofacial type patients have lowest positioned tongue.

We obtained successful functional and esthetic results by grafting of iliac marrow-cancellous bone in 2 cases of alveolar-palatal cleft patients. Bone graft of alveolar-palatal clefts provide bony support to adjacent teeth of cleft area, prevented from relapse of orthodontic arch expansion, closure of oroantral fistula and improvement of speech problem. 1. In one case, extraction of upper right central incisor that was little bone support, alignment of rotated teeth and expansion of collapsed arch segment were done with pre-orthodontic treatment. The other case. Bone grafting was done after removal of prosthesis with no pre-orthodontic treatment. 2. After mucoperiosteal incision in cleft area, the mucosal flap of labial area, palate and nose were separation and the raised nasal mucosa was sutured for closure of oroantral fistula. Then, the iliac marrow-cancellous bones were grafted to cleft site. 3. After 6 months of operation, we had seen the new bone deposition to cleft site in dental radiograph and prosthetic treatment of missing teeth were done.

OBJECTIVE: Few studies have reported direct comparative data of lumbar spine angles between direct lateral interbody fusion (DLIF) and oblique lateral interbody fusion (OLIF). The purpose of this study was to investigate the clinical and radiological outcomes of DLIF and OLIF, and determine influential factors.METHODS: The same surgeon performed DLIF from May 2011 to August 2014 (n=201) and OLIF from September 2014 to September 2016 (n=142). Radiological parameters, cage height, cage angle (CA), cage width (CW), and cage location were assessed. We checked the cage location as the distance (mm) from the anterior margin of the disc space to the anterior metallic indicator of the cage in lateral images.RESULTS: There were significant differences in intervertebral foramen height (FH; 22.0±2.4 vs. 21.0±2.1 mm, p<0.001) and sagittal disc angle (SDA; 8.7±3.3 vs. 11.3±3.2˚, p<0.001) between the DLIF and OLIF groups at 7 days postoperatively. CA (9.6±3.0 vs. 8.1±2.9˚, p<0.001) and CW (21.2±1.6 vs. 19.2±1.9 mm, p<0.001) were significantly larger in the OLIF group compared to the DLIF group. The cage location of the OLIF group was significantly more anterior than the DLIF group (6.7±3.0 vs. 9.1±3.6 mm, p<0.001). Cage subsidence at 1 year postoperatively was significantly worse in the DLIF group compared to the OLIF group (1.0±1.5 vs. 0.4±1.1 mm, p=0.001). Cage location was significantly correlated with postoperative FH (β=0.273, p<0.001) and postoperative SDA (β=-0.358, p<0.001). CA was significantly correlated with postoperative FH (β=-0.139, p=0.044) and postoperative SDA (β=0.236, p=0.001). Cage location (β=0.293, p<0.001) and CW (β=-0.225, p<0.001) were significantly correlated with cage subsidence.CONCLUSION: The cage location, CA, and CW seem to be important factors which result in the different-radiological outcomes between DLIF and OLIF.
