reconstructive techniques in the oral and maxillofacial surgical field. Further understanding of bone healing mechanism, bone physiology and bone biology, transplantation immunology, and development of tissue banking procedure has enabled oral and maxillofacial surgeons to reconstruct even the most difficult bony defects successfully with the preserved allogeneic bone implant. Now autogenous bone and allogeneic bone implants present a wide variety of surgical options to surgeons, whether used separately or in combination. The surgeons are able to make judicious and fruitful choices, only with a through knowledge of the above-mentioned biologic principles and skillful techniques. The author evaluated 116 cases where allogeneic bones were transplanted for oral and maxillofacial reconstruction.]]>

Maxillofacial Surgery through Emergency Room in Chonnam University Hospital, from Jan. 1, 1992 to Dec. 31, 1996. Result obtained were as follwes; Male predilection was shown, the male to female ratio being 2.5 to 1. The frequently developing age group were the first 3rd and 4th decade and under the age of 9 was followed. The number of patients for emergency was peak in September and October to 11%. About the causes for emergency, traffic accident was the most, and fall down injury and assault were followed. About the injury lists, facial laceration was preceded and the next facial bone fracture and the tooth injury followed. In the facial bone fracture, fracture in the mandible only was the most, and zygomaticomaxillary complex fracture, and mandible-maxilla complex fracture were followed. when the case of the mandible fracture symphysis, condyle, angle were marked in succession. 57% was predomunatly ranged in the timea of 18:00 to 03:00 for the emergency. From injury onset to visiting emergency room, the range of 8 hours to 12 hours was predominant. Above results suggest that urgent patients of oral and maxillofacial area were relatively so high that division of oral and maxillofacial surgery should be extablished immediately.]]>

Maxillofacial region include abrasion, contusion, simple laceration, laceration of skin with underlying tissue, soft tissue injuries combined with facial bone fracture and involving functional structures such as facial such as facial nerve and vessel, orbit, lacrimal duct and salivary gland and so on. The results obtained were as follows ; 1. The age range was 1 to 97, and the highest incidence occured in the 3rd decade(23.4%), followed by the 1st decade (20.2%), 4th decade(18.1%), 4th decade(18.1), and 5th decade(14.3). 2. The sexual ration was 4:1 (M:F). 3. The most common cause of facial laceration was a accident(54.5), followed by blow(17.8%), traffic accident(15.9%) and unknown(10.8%). 4. The most frequently occurred site of injury was a forehead(24), followed by oral cavity(16.9%), lip(15%), eyebrow(14.5%), cheek(14%), chin(11.8%), nose(2%), scalp(1.4%) and neck(0.9%). 5. Most of wound size was less than 3cm in length. 6. 28 patients suffered facial bone fracture, representing 7%. 7. The major complications following facial laceration were infection and facial paralysis caused by facial nerve injuries, representing 4.5% and 1.9%.]]>

Maxillofacial Surgery of Chonnam University Hospital from Jan, 1, 1992 to Dec. 31, 1996 were analyzed clinicostastically. Results obtained were as follows ; Male predominated over female by a ratio of 5.3 to 1. The frequently developing age groups were first 3rd (25%), 4th (21%) and the 2nd (18%) decade on succession. The peakest month was the Angust (16%), and May (11%), September (9%), October(9%). When it comes to the reasons for in-patients, traffic accident was predominant to 39%. In the 234 cases of midfacial fractures, zygomaticomaxillary complex fracture was the most by 37%. The most common with injury show that facial laceration marked by 49%, neurologic injury 24%, and mandibular fractures 20% each by each. About the time from injury onset to operation, 55% of eases were less than a week while the others (45%) more than a week. 3 plates were used for operation : for Le Fort I fracture, 5.5 for Le Fort I,II; I,III; II,III fracture, 7 for Le Fort I,II,III fracture were used. 20 patients (8%) appealed their complication and the most common was reported as infection. Above results suggest that early diagnosis and treatment of fracture site, systemic condition and associated injuries are necessary, and coorperative treatment with medical department should be performed.]]>
