Objectives : To demonstrate the preventive effect on post-operative spinal deformity of the laminoplasty compared with laminectomy for spinal cord tumor. Methods : Sixteen patients who underwent laminoplasty and 89 patients who underwent lamenectomy were reviewed retrospectively after removal of spinal cord tumors between February 1981 and December 1999. The mean follow-up period after laminoplasty and laminectomy were 29 months(range, 12-49 months) and 66 months(range, 6-120 months) respectively. Patients were observed neurologically and radiologically. Results : Postoperative kyphosis was observed 17 patients(19%) in the laminectomy group, but was not observed in the laminoplasty group. Postoperative slipping was observed 16 patients(18%) in the laminectomy group, but was not observed in the laminoplasty group. Complications such as postoperative scoliosis, rotation, and swan-neck deformity were observed in the laminectomy group, but were not observed in the laminoplasty group. Conclusions : Laminoplasty prevented postoperative spinal deformities after removal of spinal cord tumors, and afforded anatomic reconstruction of the vertebral arch. Additionally, appropriate patient selection maximizes the chance of optimal neurologic outcomes and minimizes complications. Laminoplasty appears to warrant further evaluation as an alternative to wide laminectomies for exposure of intraspinal tumors.

Objectives : Since vertebroplasty has been introduced, we performed short segment pedicle screw fixation with augmented intra-operative vertebroplasty in patients with unstable thoraco-lumbar fracture. Our intentions are to demonstrate the efficacy and indication of this new technique compare to conventional methods. Material and Methods : The surgery comprised of pedicle screw fixations on one level above and below the fracture site, and the fractured level itself, if pedicle is intact, and intra-operative vertebroplasty under the fluoroscopic guide with in-situ postero-lateral bone graft. Also, in cases of bone apposition, we removed those with small impactor through a transfascetal route. During the last 2 years, we performed in seven(7) unstable thoraco-lumbar fracture patients who consisted of two different characteristics, those four(4) with primary or secondary osteoporosis and three(3) of young and very healthy. All patients were followed clinically by A.S.I.A. score and radiography. Results : Mean follow up period was 14 months. We observed well decompressed state via transfascetal route in cases of bone fragments apposition and no hardware pullout in osteoporotic cases, no poly-methyl-methacrylate (PMMA) leakage through the fracture sites into the spinal canal, and no kyphotic deformities in both cases during follow-up periods. All patients demonstrated solid bony fusion except one following osteoporotic compression fracture on other sites. Conclusions : In the management of unstable thoraco-lumbar fracture, we believe that this short segment pedicle screw fixation with augmented intra-operative vertebroplasty reduce the total length or levels of pedicle screw fixation without post-operative kyphotic deformity.

Torticollis is a deformity of the neck that shows tilting of the head toward the affected side and rotation of the chin toward the opposite side. In many cases with this condition, unilateral tightness of the sternocleidomastoid muscle is found frequently with fibrous tumor. The analysis of 43 cases of congenital muscular torticollis and result of their physical therapy are reported. The research was from Jan. 1, 1990 to Dec. 31, 1995 at Ulsan Dong Kang Hospital. The results obtained were as follows. 1. There were 30 males(69.8%) and 13 females(30.2%). Age distribution of patients showed below 2 month 20 cases(46.5%), above 1 year 7 cases(16.3%), $5{\sim}6/11{\sim}12$ months 4 cases(9.3%), and $7{\sim}8$ month 2 cases(4.6%). 2. 25 cases(58.1 %) were on the right and 18 cases(41.9%) on the left side. Torticollis was mild to moderately severe in mild 22 cases(51.1 %), moderate 18 cases (41.9 %) and severe 3 cases(7%). 3. There were normal spontaneous delivery in 36 cases(83.7%), Cesaean section in 4 cases (9.3%) and breech presentation in 3 cases(7%). Sequence of birth, the 1st born babys were 30 cases(69.8%) and the 2nd born babys were 13 cases(30.2%). 4. Above fair result of physiotherapy were 36 cases(83.7%). 5. Of the 43 cases with fellow up, above fair 32 cases(74.4%) and poor 11 cases(25.6%) showed. As conclusion, passive stretch exercise of sternocleidomastoid muscle with early torticollis diagnosis seems more successful in recovery than no exercise.

Objective : Ankylosing spondylitis is an inflammatory rheumatic disease mainly affecting the axial skeleton. The rigid spine may secondarily develop osteoporosis, further increasing the risk of spinal fracture. In this study, we reviewed fractures in patients with ankylosing spondylitis that had been clinically diagnosed to better define the mechanism of injury, associated neurological deficit, predisposing factors, and management strategies. Methods : Between January 2003 and December 2013, 12 patients with 13 fractures with neurological complications were treated. Neuroimaging evaluation was obtained in all patients by using plain radiography, CT scan, and MR imaging. The ASIA Impairment Scale was used in order to evaluate the neurologic status of the patients. Management was based on the presence or absence of spinal instability. Results : A total of 9 cervical and 4 thoracolumbar fractures were identified in a review of patients in whom ankylosing spondylitis had been diagnosed. Of these, 7 fractures were associated with a hyperextension mechanism. 10 cases resulted in a fracture by minor trauma. Posttraumatic neurological deficits were demonstrated in 11 cases and neurological improvement after surgery was observed in 5 of these cases. Conclusions : Patients with ankylosing spondylitis are highly susceptible to spinal fracture and spinal cord injury even after only mild trauma. Initial CT or MR imaging of the whole spine is recommended even if the patient's symptoms are mild. The patient should also have early surgical stabilization to correct spinal deformity and avoid worsening of the patient's neurological status.

Purpose: The purpose of this study is to evaluate the results of alveolar bone grafting in patients with various types of cleft lip and to compare the success rates according to the lateral incisors and canines. Methods: The postoperative radiographs of 20 patient with a cleft lip and alveolar process alone (CLAP), complete unilateral cleft lip and palate (UCLP) and complete bilateral cleft lip and palate (BCLP) were retrospectively analyzed. The alveolar bone height was classified according to ${\AA}$byholm (1981) and Bergland (1986) and we evaluated the dentition at the time of surgery and the existence of a lateral incisor and impacted canines. Results: 16 (80%) of the 20 patients were assigned to Type I & II and they were considered successful. In the UCLP group, the success rate was significantly better than that of the UCLP and BCLP groups. The success rate was significantly better than when the cleft was grafted with the existence of a lateral incisor and before the eruption of the canines. Conclusion: The severity of the deformity influenced the success rate. The timing of the operation was a critical variable that affected the outcome in patients with cleft lip and palate.

안면비대칭의 주원인은 하악골이며, 하악골의 비대칭 성장에 대한 상악골의 보상성장에 따라 교합면 경사 등이 초래된다. 디지털 사진과 삼차원 CT 등 다양한 방법으로 정확한 진단을 하고 수술을 포함한 치료계획을 세운다. 술전 교정 치료는 상악골과 하악골 치열의 치성 보상(dental compensation)을 제거하면서 상악 치열의 중심은 상악골의 정중선에, 하악 치열의 중심은 하악골 정중선에 맞게 이동하여 술후 상하악 치열궁이 일치하면서 동시에 안모 정중선에 일치하게 맞추어야 한다. 악교정 수술은 일반적으로 상하악 동시 수술을 하게 되며 우각부 풍융도 교정과 이부 성형술(genioplasty) 등을 부가적으로 할 수 있으며, 교합면 경사 교정과 수평 회전 등의 이동이 상하악 위치에 서로 영향을 주면서 수술 후 안모 변화에 대한 예측을 어렵게 만들기 때문에, 다양한 분석을 통해 정확한 예측으로 최선의 결과를 얻는 것이 가장 중요하다.

Purposes: Wide scars occurring on the lower face and neck are a source of both functional and esthetic problems. Consequently, we can use skin grafts, pedicled flaps, free flaps, and tissue expansion for the reconstruction of this area. Compared with other reconstruction techniques, tissue expansion is advantageous in that it enables the maintenance of a color and texture similar to that of the adjacent tissue. However, the conventional method of tissue expansion has been reported to lead to an unnatural cervicomental angle and to the deformity of adjacent structures. We have therefore made efforts to prevent these problems through the use of several operative procedures. Methods: Forty-one patients with lower facial and cervical scars underwent tissue expansion. The tissue expansion was performed using a rectangular-shaped Nagosil$^{(R)}$ tissue expansion device. On insertion of the tissue expander, the intermediate area of superficial fat layer was dissected and then the tissue expander was inserted to make a flap that was as thin as possible. In advancement of the flap, a capsule-formed by the tissue expander-was used for the interrupted fixed suture of the flap to the fascia of the platysma muscle of the neck. This procedure was performed multiple times and also performed between the flap and the periosteum of the mandible, such that the tension was removed during the suture of the flap margin. Finally, the patients were fitted with a Jobst$^{(R)}$ facial garment in order to stabilize the operation site at least twelve months. Results: The most prevalent location of the scar was the cheek (15 cases), followed by the chin in 14 cases and the neck in 12 cases. The mean size of scar was $55.7{\pm}39.4cm^2$. Conclusions: Using our procedures, we have experienced no significant deformities and have also achieved a more natural cervicomental angle in the patients.

구순 구개열을 가지는 성인 남자 17명의 두 부계측방사선 사진을 McNamara씨 분석법을 중심으로 하여 정상 대조군과 비교하여 다음과 같은 결론을 얻었다. 구순 구개열 환자에서 Na. perpendicular to point A. SNA angle이 통계적으로 유의하게 작게 나와 두개저에 대해 상악이 후방에 위치하였다(p<0.01). Effective maxillary length, Maxillomandibular differential, Wit's appraisal 등이 구순 구개열 환자와 대조군에서 통계적으로 유의하였으나 Effective mandibular length, Mandibular plane angle, Facial axis angle, Lower anterior facial height 등은 유의하지 않았다. 이는 하악의 경사도, 성장방향 등은 정상이나 상악의 절대적인 길이가 작으며 이로 인하여 상하악간의 부조화가 생긴 것으로 사료된다. 구순 구개열 환자에서 pogonion to Na. perpendicular가 95% 신뢰구간에서 통계적으로 유의하게 작게 나와 하악이 두개저에 대해 상대적으로 후방에 위치하였다. 교정치료에도 불구하고 point A에 대해 상악 전치가 상대적으로 후방에 위치하였다.
