Access to the craniofacial skeleton and skull base requires osteotomies. An adequate exposure of neoplasms occupying the skull base and the oral cavity and oropharynx, especially retromolar trigone, is very important for precise tumor ablation. The demonstration by Tessier of the capacity for large segments of bone to survive removal and replacement has enabled skull base tumor surgery to grow into a subspeciality. Through the refined craniofacial exposure osteotomies, the surgery is safer, the operation shorter, and the result better both oncologically and reconstructively. We experienced 24 cases of exposure osteotomies consisting of 12 cases transzygomatic approaches, 1 case tranglabellar osteotomy, 1 case lateral transmaxillary approach, 1 case Le Fort II & midline splitting, and 9 cases mandibulotomy. There was no significant complication except a local wound infection in transzygomatic approach and one case of minimal malocclusion after parasymphyseal mandibulotomy. The orthotopic bone graft and the rigid fixation enables the postoperative morbidity to decrease. It seems that the previously inaccessible craniofacial tumors can be treated through the various exposure osteotomies.

Achilles tendon is the most powerful and the biggest tendon of the body and its rupture is frequently sports-related. Many authors reported the effects of mobilization, electricity, ultrasound and various drugs as factors influencing the injured tendon. We studied the effects of early passive mobilization after firm suture using plantaris tendon as tension suture material and reinforcing membrane on the repair of a ruptured Achilles tendon. From March 1992 to December 1995, twenty-two operations on the Achilles tendon were carried out in our hospital. 1. Fourteen patients were male and eight patients were female. The mean patient age was 38 years, ranging from 13 to 68 years. Average follow-up periods was 2 years and 7 months, ranging from 12 months to 3 years and 8 months. 2. The rupture site was 4.7cm proximal to the tendon insertion into the calcaneus on average. 3. We performed the operations with end to end suture technique. After approximation of the ruptured ends of the tendon with a No. 5 Ethibond tension suture using a modified Kessler stitch, placed plantaris tendon in a fascial needle and pass it circumferentially and distal plantaris tendon is fanned out and tacked over the repair. 4. Postoperative treatment was done as following protocol Short leg cast was done with equinus position for initial 3 weeks, and then cast was removed, hydrotherapy and passive exercises was employed. About 6 weeks after operation when the foot can be brought to right angle, a reverse 90degrees ankle stop short leg brace was applied for additional 6 weeks and partial weight bearing was aUowed. 5. Follow-up results were classified according to the Arner-Lindholm scale. We had 16 excellent results and 6 satisfactory results. After rigid suture it may be possible to introduce a regimen of progressive isometric stimulation and protected loading and streching combined with removable orthosis. Such early exercises are likely to improve the rate of rehabilitation over plaster immobilization.

We developed Extor pins for Extor external fixator, it made of stainless steel and applied it clinically to manage open fractures and chronic osteomyelitis from December, 1993 to January, 1995. The main aim of present study is to compare the mechanical strength and biocompatibillity between Extor pins and AO Schanz pins, and to determine the safety and possibility of clinical use. We performed the biomechanical test for bending, tension, and shearing of pin itself using universal testing machine (LR5OK) and pullout test in cadeveric cortical femur to determine the bone holding power. There was no significant difference between Extor and AO Schanz pin (p>0.05). Clinically, the incidence of pin site infection, pin lossening, radiological rarefaction, and pathological change were not different significantly (p>0.05). Although Extor pins are somewhat different from AO Shanz pins in material and design characteristics, we can find the safety and possibility of clinical use of Extor pins made in Korea.

The elbow is the most frequent area of complaint in children and adolescent baseball players. The physical stresses associated with repetitive throwing create extra-ordinary forces, which may affect the normal osteochondral and soft tissue developmental process and are the important factors causing the decrease of competitive power and shortening of life as a baseball player in adolescents. We surveyed the 114 baseball players of middle & high school in Taegu in order to evaluate the prevalance of symptoms and radiologic findings of the elbow and correlation of these findings to career & position of the baseball game. The results were as follows. 1. Of 114 players, 83 were non-pitchers and 31 were pitchers. The mean career was 3.8 years (7 months to 6 years). 2. The 77 players (67.7%) had the pain on their elbow during or after daily exercise. Other clinical symptoms were locking (30.7%), limitation of motion (18.4%), swelling (16.6%) and clicks on motion (10.5%). 3. On the radiogram of the elbow, hypertrophy or separation of medial epicondyle were seen in 34% of players, loose bodies in 17%, hypertrophy of the humerus in 12% and cystic change of the capitellum in 11%. 4. The mean career of symptomatic players was 4.4 years but non-symptomatics was 2.7 years. The mean career of players who had abnormal radiologic findings was 5.1 years but 3.1 years in players who had no abnormal radiologic fingings. 5. Symptoms and pathologic changes were more common in the elbow of pitcher' s group due to throwing frequency & pitching style. 6. Among the 77 players who had any kinds of problem of the elbow, 49 players of them had no experience of visiting hospital. 7. To prevent these injuries of the elbow, the following recommendations were made. First, restrict the number of innings pitched per game. Second, avoid throwing the curve ball in this age group. Third, ensue an adequate warm up period before exercise or rest after games. Fourth, inform parents and coaches of possible harmful nature of excessive throwing.

STUDY OBJECTIVES: To identify the value of symptoms in head trauma patients with alert mental status requiring a head CT scan. METHODS: A retrospective study was performed at an emergency center over 8 months period. Patients(age > or = 7) were enrolled if they presented with a Glasgow Coma Scale score of 15 and underwent head CT after head trauma. The symptoms and signs were recorded in the entry forms prior to head CT The symptoms found in the patients with normal CT were compared with those in abnormal CT showing intracranial injuries. RESULTS: Among the 168 patients, traumatic intracranial abnormality was identified in 34(20.2%) by CT. Skull fracture was idendified in 8(4.8%) in normal CT, 17(10.1%) in abnormal CT group by simple X-ray and CT. In the normal CT group without skull fracture, 65(52.0%) had headache, 61(48.8%) had loss of consciousness( LOC), 43(34.4%) had vomiting, 24(19.2%) had nausea, 7(5.6%) had dizziness. In the abnormal CT group without skull fracture, 14(77.8%) had heacache, 9(50.0%) had LOC, 9(50.0%) had vomiting, 2(11.1%) had nausea, 2(11.1%) had dizziness. The patients with headache were significantly more common in the abnormal CT group. CONCLUSION: A head CT is required in alert head trauma patients with any symptoms and signs of intracranial injuries, especially with headache.

Capsule contraction syndrome is severe constriction of the anterior capsular opening and equatorial capsular bag diameter after extracapsular cataract surgery. It is relatively common in patients with continuous curvilinear capsulorhexis, but rarely in can-opener capsulotomy or anterior radial capsular tears. It is due to capsular bag contraction from fibrous dysplasia of residual lens epithelial cells with weakened zonular resistance. We experienced a case of capsule contraction syndrome in a 72-year old woman with retinitis pigmentosa, who had phacoemulsification following an intact 5.0mm-continuous curvilinear capsulorhexis 4 months before. After successful YAG laser radial anterior relaxing capsulotomy, her visual acuity restored to 0.3, limited by cystoid macular edema.

Trabeculectomy with mitomycin C was performed on three patients with traumatic dislocate crystalline lens and refractory secondary glaucoma, combined with pars plana vitrectomy, intravitreal phacofragmentation and scleral fixation of the IOL. Over nine months after operations, intraocular pressures were well controlled not only without any antiglaucomatous medications and special complications but also with good visual recovery in all patients . Trebeculectomy combined with pars plana vitrectomy may be useful in some patients wit hvireoretinal disease and glaucoma.
