Purpose: The treatment of children mandibular condyle fracture that is severely displaced is controversial. The conservative treatment of it may lead to complications - mandibular deficiency, asymmetry, malocclusion and temporomandibular joint dysfunction. Moreover, open reduction carries risks for growth retardation, facial nerve injury, scarring and joint stiffness. The aim of this article is to present an alternative technique of the treatment by using a threaded Kirschner wire and external rubber traction. Materials: From November 2005 to May 2008, three patients underwent the management by using a threaded Kirschner wire and external rubber traction. A threaded Kirschner wire was inserted in the condylar segment by using a C-arm. We applied the external rubber traction, and we reducted the segment progressively until complete reduction. The mandibular - maxillary fixations were removed after 3 weeks, and patients went into training for mouth opening. Results: The technique didn't result in complications - joint dysfunction, facial nerve injury, sore, infection and nonunion during follow - up period. Radiologic follow - up examinations revealed correct reduction in all patients. In all cases, we found restoration of preinjury occlusion and temporomandibular joint function. Conclusions: Closed reduction of children mandibular condyle fracture by using a threaded Kirschner wire and external rubber traction did achieve anatomic reduction and restore mandibular height. This alternative technique is simple, effective, inexpensive, easy to apply and minimally invasive.

다발성 안면골절 시 연조직 및 경조직의 소실로 인해 적절한 과두-디스크의 기능을 회복할 위치를 찾는데 어려움이 있다. 다발성 안면골절 및 양측 과두골절과 부족한 수직고경 및 안면비대칭을 가진 환자가 내원하였다. 교합안정장치를 이용하여 골절된 과두를 정복하고 과두-디스크 복합체에 새로운 기능적 위치를 선정하였다. 추적조사를 통해 과두의 위치가 편안감과 안정성이 적절하다고 판단한 뒤 임플란트와 고정성 보철물을 이용한 완전구강회복을 시행하였다. 환자는 심미성과 기능에 만족하였으며 안정적 교합상태를 보였지만 추가적인 교합변화의 가능성을 배제할 수 없기 때문에 야간안정장치 및 정기적인 관리가 필요할 것으로 사료된다.

Background: The standard treatment of nasal bone fractures in pediatric patients is closed reduction. Conservative treatment is sometimes performed, but poses a risk of nasal deformity. The aim of this study was to evaluate the outcomes of bone remodeling in pediatric nasal fractures. Methods: Information was extracted from the medical records of patients under 12 years of age who received conservative treatment for a nasal bone fracture and underwent follow-up computed tomography (CT) examinations. The initial fracture and its outcomes over time were graded as excellent, good, or fair according to the malalignment, displacement, or irregularity of the fractured segments. The outcomes of remodeling were evaluated through changes in the grade of the fracture between initial and subsequent CT scans. Results: The review identified 16 patients between March 2015 and December 2019. Their mean age was 6.2 years, and the average follow-up period was 4.9 months. Three of the five patients with a plane I frontal impact showed improved outcomes of remodeling from good to excellent, and the remaining two patients, improved from fair to good. Eight of the 11 patients with plane I lateral impacts showed improved outcomes, from good to excellent, while one patient, improved from fair to good, one patient, improved from fair to excellent, and one patient showed no interval changes. Conclusion: In 15 of these 16 patients with non-severe fractures, the bony contour improved through remodeling, without surgical intervention. Therefore, we suggest that conservative treatment is a feasible option for mild pediatric nasal fractures.

Background: When performing reduction of zygomatic arch fractures, locating the inward portion of the fracture can be difficult. Therefore, this study investigated the discrepancy between the locations of the depression on the soft tissue and bone and sought to identify how to determine the inward portion of the fracture on the patient's face. Methods: We conducted a retrospective review of chart with isolated zygomatic arch fractures of type V in the Nam and Jung classification from March 2013 to February 2022. For consistent measurements, a reference point (RP), at the intersection between a vertical line passing through the end point of the root of the ear helix in the patient's side-view photograph and a transverse line passing through the longest horizontal axis of the external meatus opening, was established. We then measured the distance between the RP and the soft tissue depression in a portrait and the bone depression on a computed tomography (CT) scan. The discrepancy between these distances was quantified. Results: Among the patients with isolated zygomatic arch fractures, only those with a fully visible ear on a side-view photograph were included. Twenty-four patients met the inclusion criteria. There were four types of discrepancies in the location of the soft tissue depression compared to the bone depression: type I, forward and upward discrepancy (7.45 and 3.28 mm), type II, backward and upward (4.29 and 4.21 mm), type III, forward and downward (10.06 and 5.15 mm), and type IV, backward and downward (2.61 and 3.27 mm). Conclusion: This study showed that discrepancy between the locations of the depressions on the soft tissue and bone exists in various directions. Therefore, applying the transverse and vertical distances measured from a bone image of the CT scan onto the patient's face at the indicated RP will be helpful for predicting the reduction location.

Luxation of the hip is the most common luxation seen in small animals. Luxations are classified by the direction in which the femoral head lies in relation to the acetabulum and craniodorsal luxations are the most common type. Recommendations for treatment are based on the presence of preexisting disease, the type and duration of luxation and severity of concurrent injuries. In this study modified external skeletal fixation was used for craniodorsal coxofemoral luxation in 5 dogs. Luxated head Joint was reduced and fixator pins were applied into the greater trochanter, the middle point of iliac body and the lateral surface of sacroiliac joint in a closed fashion. Reduction was successful in 4 of the 5 operated limbs. Complications noted in this study included pin tract drainage, pin loosening and secondary fracture at the pin insertion site.

Cerebral venous sinus thrombosis (CVST) following a closed head injury in pediatric patients is a rare condition, and an early spontaneous recanalization of this condition is extremely rare. A 10-year-old boy was admitted with a mild, intermittent headache and nausea five days after a bicycle accident. The brain computed tomography showed an epidural hematoma at the right occipital area with pneumocephalus due to a fracture of the occipital skull bone. The brain magnetic resonance imaging and the magnetic resonance venography demonstrated a flow signal loss from the right sigmoid sinus to the right jugular vein. The diagnosis was sigmoid sinus thrombosis, so close observations were selected as a treatment for the patient because of his gradually improving symptoms; however, he complained of vomiting 14 days the after conservative treatment. The patient was readmitted for a further examination of his symptoms. The laboratory and the gastroenterological examinations were normal. Due to concern regarding the worsening of the sigmoid sinus thrombosis, the brain magnetic resonance venography was rechecked and it revealed the recanalization of the venous flow in the sigmoid sinus and in the jugular vein.

The purpose of this study was to investigate the radiographic images of the condylar head in clinically normal subjects and the TMJ patients using standardized projection technique. 45 subjects who have not clinical evidence of TMJ problems and 96 patients who have the clinical evidence of TMJ problems were evaluated, but the patients who had fracture, trauma and tumor on TMJ area were discluded in this study. For the evaluation of radiographic images, the author has observed the condylar head positions in closed mouth and 2.54㎝ open mouth position taken by the standardized transcranial oblique lateral projection technique. The results were as follows: 1. In closed mouth position, the crest of condylar head took relatively posterior position to the deepest point of the glenoid fossa in 8.9 % of the normals and in 26.6% of TMJ patients. 2. In 2.54㎝ open mouth position, condylar head took relatively posterior position to the articular eminence in 2.2% of TMJ patients and 39.6% of the normals. 3. In open mouth position, the horizontal distance from the deepest point of the glenoid fossa to the condyla head was 13.96㎜ in the normals and 10.68㎜ in TMJ patients. 4. The distance of true movement of condyalr head was 13.49㎜ in the normals and l0.27㎜ in TMJ patients. 5. The deviation of mandible in TMJ patients was slightly greater than that of the normals.

The purpose of this communication is to review the 390 cases of chest trauma, treated at Department of Thoracic and Cardiovascular Surgery, School of Medicine Kyungpook National University from 1960 to 1977. Patients were grouped into two: group `60s [1960-1969] of 103 cases and group `70s [1970-1977] of 257 cases. As the number of cases of each group showed, chest trauma cases increased three times in `70s . The main causes of trauma were auto accident, falling down, industrial injury and stab wound in that order for both groups. Eighty per cent of cases of `60s were between 20 and 59 years and 73.8% of same age range for `70s. Rib fracture of fourth to eighth rib was the most common lesion in both `60s and `70s group. The incidence of hemothorax or hemopnemothorax significantly increased among `70s group than `60s. Clinical manifestations of chest pain and dyspnea remained most frequent symptoms for both groups. The pertinent principles of treatment for the chest trauma were conservative therapy, closed thoracotomy and open thoracotomy. Closed thoracotomy was performed more freely during the period of 1970-1977, with encouraging clinical results. Very few cases of complications other than pneumothorax or hemopneumothorax occurred. Those are fibrothorax, asphyxia, atelectasis and mediastinitis. The overall mortality was 3.9% for the `60s and 2.1% for the `70s group. The possible causes of death of 14 cases of chest trauma whom died on arrival during 1970-1977 were analyzed.
