Hyperbaric oxygen therapy(HBO) is defined as breathing 100% oxygen while in an enclosed system pressurized to greater than on atmosphere(sea level). This increased oxygen delivery furthers your body's ability to kill germs and to increase healing. HBO is a supplemental therapy to be used in addition to the current medical and surgical therapy you are receiving. HBO typically is used to complement treatments of medical problems such as bone infections, complication of radiotherapy, and certain chronic, non-healing wounds. On an emergency basis, the chamber also is used to treat problems such as carbon monoxide poisoning and the decompression sickness. We analysed stastically cases which are treated by hyperbaric oxygen therapy in point of oral and maxillofacial region on the Kangnam General Hospital for aid in comprehension and application of this therapy. Total 760 patients were treated at Gangnam Gneral Hospital from July 1996 to September 1999. They were classifed by region to Decompression sickness(DCS), Carbon monoxide poisoning(CO), General surgery(GS), Orthopedics(OS), Oral and Maxillofacial surgery(OMFS), others. Patients of Oral and Maxillofacial surgery were divided by diseses to Osteomyelitis, Osteoradionecrosis, Reconstruction, Bone graft, Difficult wounds, others. The results were as follows. 1. This institute conducts HBO therapy for DCS which takes up 62% and 10.5% for OMF region. 2. In OMF region, Osteomyelitis is 40%, Osteoradionecrosis is next, Bone graft, and Reconstruction is a row. 3. According to our precious study, HBO has been frequently conducted in OMF region compared to past, however, it is less actively conducted in this area for reserch than other conturies. Therefore, We need further application to the clinical use.

There have been many trials to decrease the scar formation followed by wound treatment. TGF-beta plays a important role on wound healing in adult. Therefore the repression of TGF-beta expression will be helpful to decrease scar formation. Decorin is known to competitively inhibit TGF-beta expression. Decorin were subcutaneously administered in surgical wounds in rabbits to investgate the preventing effect of scar formation for clinical application. Histologic findings of wound healing progresses is similar with control and experimental group at 2week. 2.5 microgram decorin of administrated group was similar to those of control group at 4 and 8week. In wound healing process 10 microgram decorin of administrated groupsat showed that thickness of immature collagen fibers(scar) was decreased as compared with control group at 4, 8 weeks. 20 microgram decorin of administrated group showed similar histologic features to 10 microgram administrated group. The wounds of 8week experimental group(10, 20 microgram) were completely recovered to the normal surrounding skin tissue including sweat gland and hair follicle. These results suggested that decorin can be of help to the prevention of local scar formation.

BACKGROUND: About half of the world population is infected with H. pylori, but the transmission and the source of this infection are still unclear. Recently, dental plaque (DP) and saliva have been implicated as possible sources of H. pylori infection. This study was done to investigate the detection rates of H. pylori in the DP and saliva by use of PCR depending on H. pylori infection state of gastric mucosa. METHODS: In 46 subjects, gastric H. pylori colonization was evaluated with CLO test, microscopy of Gram stained mucosal smear, culture and histology after modified Giemsa staining in the antrum and body, respectively. A patient was regarded as H. pylori positive if one or more of the four aforementioned test methods demonstrated H. pylori colonization of the gastric mucosa. For detection of H. pylori in the DP and saliva, PCR assay was done with ET4-U and ET4-L primers. To estimate the sensitivity and specificity of this PCR, H. pylori positivity was evaluated in the antrum and body, separately. RESULTS: The sensitivity of mucosal PCR was 50.0% (27/54) and the specificity 86.8% (33/38). When a subject was regarded as H. pyloi positive, if either antrum or body mucosal H. pylori was is positive, the positive rate of mucosal PCR was 62.1% (18 subjects) in the 29 H. pylori-positive and 17.6% (3 subjects) in the 17 H. pylori-negative subjects. DP PCR was positive in 2 of 29 H. pylori-positive subjects (6.9%) and none in the 17 H. pylori-negative (0%). Saliva PCR was positive in 4 of 14 H. pylori-positive subjects (28.6%) and none of 6 H. pylori-negative (0%). CONCLUSION: The detection rates of H. pylori in DP and saliva by PCR were rather low, 6.9% and 28.6%, respectively, and these rates might have been underestimated by low sensitivity of the PCR method used in this study. However, the results that H. pylori was found in the DP and saliva suggest that the oral cavity can perform a role as a reservoir of H. pylori in Korea.

The facial esthetics are much affected by nasal changes due to especially its central position in relation to facial outline and so appropriately evaluated should be the functional and esthetic aspects of the nose associated with the facial appearance. Generally, a maxillary surgical movement is known to induce the changes of nasolabial morphology secondary to the skeletal repositioning accompanied by muscular retraction. These changes can be desirable or undesirable to individuals according to the direction and amount of maxillary repositioning. We investigated the surgical changes of bony maxilla and its effects to nasal morphology through the analysis of the lateral cephalogram in the Le Fort I osteotomy. Subjects were 10 patients(male 2, female 8, mean age 22.3 years) and cephalograms were obtained 2 weeks before surgery(T1) and 6 months after surgery(T2). The surgical maxillary movement was identified through the horizontal and vertical repositioning of point A. Soft-tissue analysis of the nasal profile was performed employing two angles: nasal tip projection(NTP), columellar angle(CA). Also, alar base width(ABW) was assessed directly on the patients with a slide gauge. The results were as follows: 1. Both anterior and superior movement above 2mm of maxilla rotated up nasal tip above 1mm. Either anterior or superior movement above 2mm of maxilla made prediction of the amount & direction of NTP changes difficult. Especially, a correlation between horizontal movement of maxilla and NTP rotated-up was P<0.01. 2. Both much highly anterior and superior movement of maxilla is accompanied by more CA increase than either highly. Especially, the correlation between horizontal movement of maxilla and CA change was P<0.05. 3. Anterior and/or superior movement of maxilla was accompanied by the unpredictable ABW widening. 4. The amount of changes of NTP, CA, and ABW is not in direct proportion to amout of anterior and/or superior movement of maxilla. 5. Nasal morphologic changes following Le Fort I osteotomy are affacted by not merely bony repositioning but other multiple factors.

Facial and head pains are common symptoms and etiology is recognized in majority of cases, However, in some instances, the complex anatomy and emotional overlay make diagnosis difficult. The key components of any differential diagnosis are thorough knowedge of the anatomy, including the neuologic and vascular distributions, and adetailed history, Closed locking of the TMJ has been ascribed to internal derangment secondary to anteromedial disk displacement without reduction. Although the true etiologic fator of disk displacement and the process of the devolopment of internal derangment have notbeen clarified, many clinical, surgical arthrographic, and arthroscopic studies support this concept of the cause. A condition of sudden, severe, and sudden, severe, and persistant limited mouth opening, which readily responds to arthrocentesis, is postulated to a vacuum between disc and fossa in the upper compartment of temporomandibular joint. This simple treatment was found to be highiy effective in restablishing normal opening and relieving pain. Thirty-four patients(39 joints) who had sudden-onset. persistent limited mouth opening were of this study. These patients who complained TMD was treated by this arthrocenthesis limited mouth opening were subjects of this study. These patients who complained TMD was treated by this arthrocenthesis. The overall improvement, as expressed in pain and dysfunction level was 74.4%, with no recurrence of severe closed lock. So the authour thinks that this arthocenthesis is simple, effective and predictable procedure.
