This is a retrospective study on maxillofacial fractures of Korean. The study was based on a series of 510 patients who had been treated for maxillofacial bone fractrues as in-patient at Yon Sei University Medical Center for the period of January, 1982 to June, 1985. The results were obtained as follows ; 1. The ratio of Male/Female was 3.9:1, and 2nd decade (34.9%) was the highest age group in incidence, and age range was 15/12 years to 76 years. 2. Traffic accident (45.1%), fighting (21.0%) were the most common causes of maxillofacial bone fractures. 3. The frequent locations of maxillo facial fractures were mandible (50.8%), zygoma and zygomatic arch (26.2%), nasal bone (8.1%) and others, in order. 4. In mandibular fractures, isolated fracture of mandible showed 86.8%, symphysis (46.7%), condyle (23.4%) and angle (19.6%), in order. 5. In fracture of maxilla, isolated maxilla, fracture was relatively low (25.7%), and zygomatic complex fracture was divided into zygomatic complex (63.8%) and zygomatic arch (31.6%). Bilateral fracture showed 4.6% and it demonstrated whether isolated or combined with other facial bones, but fracture pattern of midface was extremely variable. 6. Treatment of maxillofacial fractures was rendered open reduction in most of cases. 7. Associated injuries of maxillofacial fractures demonstrated head(49.3%), lower extremities (16%) and upper extremities (11.8%).

The main objective of this study was to observe the antimicrobial effect of hyperbaric oxygen therapy (HBO) on the infected microorganisms, aerobic and anaerobic, of the mandibular osteomyelitis in Albino rats. The experimental osteomyelitis was induced by formation of bone hole into the medullary cavity and inoculation of Staphylococcus aureus as aerobic microorganism, and Bacteroides melaninogenicus as anaerobic microorganism separately. Author used 170 rats (Sprague-Dawley strain) dividing into a pilot study (30), aerobic osteomyelitis (80) and anaerobic osteomyelitis (60) groups. In aerobic osteomyelitis caused by S. aureus, the treatment regimen consisted of HBO (2hrs, daily at 2.4 atm.), cephalexin, a combination of both and/or no treatment control group, and in anaerobic osteomyelitis caused by B. melaninogenicus, the treatment regimen consisted of HBO once a day, HBO twice a day and/or no treatment control group, and the results were compared microbiologically. The obtained results were as follows; 1. In vitro study, hyperbaric oxygen therapy (HBO) on Staphylococcus aureus has no direct bacteriostatic effect compared with control group in ambient air, due to similar bacterial growth, and combination of HBO and antibiotic therapy revealed similar antimicrobial effect compared with antibiotic therapy alone. 2. In treatments on experimental osteomyelitis caused by Staphylococcus aureus, HBO is at least as effective as antibiotic therapy, and no significant difference was revealed between HBO group and a combination of HBO and antibiotic therapy group statistically. 3. In vitro study, antimicrobial effect of HBO on Bacteroides melaninogenicus revealed statistical significant difference compared with control group, and HBO twice a day for 4 hours was more effective than HBO once a day for 2 hours in bactericidal effect. 4. In treatment on experimental osteomyelitis caused by Bacteroides melaninogenicus, HOB group revealed high recovery rate compared with control group, while there was no significant difference between HBO once a day and HOB twice a day groups statistically. Hyperbaric oxygen therapy was effective in anaerobic osteomyelitis due to B. melaninogenicus by antibacterial activity and improvement of healing process, while it did not appear to be related to antibacterial activity in aerobic osteomyelitis due to S.aureus. Therapeutic effectiveness of hyperbaric oxygen therapy must be considered as an adjunctive treatment of refractory chronic osteomyelitis in respect that it is at least as effective as antibiotic therapy.

증예보고 : 구강저에 발생한 Dermoid cyst ( 유피낭포 ) 의 치험예

The authors treated a case of dermoid cyst of the floor of the mouth by surgical removal via extraoral approach end examined histopathologically. The case could be summarized as : 1. this 25-year-old male patient visited to our dept. of Oral Surgery, complaining of recurrent swelling on mouth floor and submental region since about 5 years ago. 2. this is a relatively rare case of dermoid cyst arised in floor of the mouth which extended through geniohyoid and genioglossus muscles. 3. Surgical removal of the lesion was performed through external approach and good result was achieved without any complications.

An introduction of three-dimensional cephalometric analysis of facial asymmetry which we currently used is illustrated with a case of facial asymmetry due to deviation prognathism, Rt. side. Posteroanterior projection and submental-vertical projection were useful to measure and record the three-dimensional relationships of anatomic structures to one another in craniofacial asymmetry, rather than lateral cephalogram.

This is a case report that keyhole partial glossectomy was carried out in remaining macroglossia after orthognathic surgery in mandibular prognathism. 1. An excision with keyhole shape reduced length, width in the molar region of tongue. 2. Intermaxillary fixation was removed on the third day after operation and resembled to normal appearance on the tenth day. 3. Speech, sensory, swallowing and tongue movement have been within normal limit.

The authors treated a case of Aspergillosis in Lt. maxillary sinus by Caldwell-Luc operation and examined histopathologically. 1. Aspergillosis is diseased condition caused by species of Aspergillus which are ubiquitous in nature and marked by inflammatory granulomatous lesion. 2. This is a rare case of Aspergillosis involved Lt. maxillary sinus without bony destruction of adjacent structures. 3. Surgical removal of the lesion was performed via Caldwell-Luc approach and good result was achieved without any complication.

This is a case report of 3 impacted canines in unusual position which were treated by surgical removal. The results are as follows; 1. Maxillary and mandibular canine impaction could be revealed by routine radiographic examination rather than patient s complaint. 2. The degree of rotation of impacted canine was various, affecting the curvature of the apex. 3. Combined orthodontic-surgical managements for artificially aided eruption should be considered first, but, if these procedures are not feasible and complication is anticipated, surgical removal should be urged at an early age.

This is to report about new-approaches for treatment of the mid-facial bone fractures. The authors treated successfully two cases of comminuted fracture of the mid-facial bones and one case of coronal and facial deformity due to craniectomy and malunited zygoma complex by coronal and temporal flap approaches. Two cases were treated by coronal flap and one case was treated by temporal flap. These approaches gave many excellent benefits to the operator and patients than other conventional methods of treatment of the mid-facial bone fractures. The results are as follows: 1. Coronal and Temporal Flap approaches were excellent for the fine reduction of comminuted fracture fragments of Zygomatico-maxillary complex and the late reduction of malunited Zygoma complex, because these offered wide operating-field to supra-and lateral orbit rims, zygomatic body and zygomatic arch. 2. These approaches gave excellent cosmetic benefits to the patients due to complete hiding of post-op. scar in hair, and were less danger to important anatomic structures as facial nerves and vessels in spite of radical exposure. 3. Pre-op. orientation and education about safety results may be necessary to the patients and relatives for minimizing of psychological phobia or anxiety to radical scalp incision. 4. These approaches will provide many benefits to the Cranio-Maxillary Orthognatic Surgery sooner or later.
