maxillofacial deformity such as facial asymmetry, micrognathia, malocclusion. For treatment of TMJ ankylosis, various surgical interventions were devised ; condylectomy, gap arthroplasty, interpositional arthroplasty and TMJ reconstruction. So, we report our results with documental study and cases of true ankylosis in our department.]]>

maxillofacial surgery. From October, 1998 to March, 1999, dental laser was used in 70 cases. Male patients were 38, female 32. The age ranged from 5 to 77, with a mean of 45.4. Indicated cases were 18 chronic periodontitis, 11 infections, 6 atypical pain, malignant or benign tumor, precancerous lesion, abnormal frenum, TMJ disorder, mucocele, and so forth. CO2 laser(Sharplan 15F, Sharplan Co.) was used in 40 cases, Ho-YAG laser(Duopulse 2000, Excel Co.) 11, Nd-YAG(Duopulse 2000, Excel Co.) 18. We present and discuss about the objectiveness, availability, and future application of laser with case reports.]]>

Maxillofacial Surgery of Wankwang University Hospital from Jan. 1, 1993 to Dec. 31, 1997. The results were as followes: Male predominated over female by a ratio of 4.6 : 1. The most common reasons is traffic accident(88.2%). The elapsed time from injury to operation is average 9.2 days, and the mean admission days were 79 days and removal of plates were average 217.3 days. The most associated facial bone fractures is Zygomatico-Maxillary complex fracture(20%). Associated injuries were neurologic injury(29.4%), orthopedic injury(23.5%), opthalmologic injury(17.6%), body injury(5.8%), neuropsychologic injury(5.8%) and otolaryngologic injury(5.8%) in this order. The most injured teeth were upper and lower incisors. The intubation methods for surgery were orotracheal(29.57%), submental (29.5%), and nasotracheal technique(41%). Most patients had complications, that were post-traumatic telecanthus, nasal depression, scar formation. This results suggest that early diagnosis and treatment is prerequisits to satisfactory result. Aggressive management of NOE fracture with direct or bicoronal exposure with aid of CT is now an accepted norm.]]>
