Background: The aim of our retrospective study is to evaluate the management of isolated orbital floor fractures considering the clinical, functional and aesthetic results according to the surgical approach and the type of materials used. Methods: Retrospectively, clinical, radiological, surgical, and ophthalmological data from 79 patients were collected from January 2010 to December 2016. Furthermore, included patients were interrogated on functional and aesthetic satisfaction. Results: The main causes of trauma were physical aggression followed by accidents. The median time between trauma and surgery was 4 days. The most common surgical approaches were the subciliary and the transconjunctival ones. Alloplastic materials were used in 75 patients. In two patients, we used a combination of two grafts. Patients experienced minor immediate complications. On follow-ups, none of our patients suffered from ocular movement restrictions. Patients treated by subciliary approach had higher risk of retractile scaring compared to other surgical approaches. In our study, patients agreed to complete a questionnaire assessing functional and aesthetic outcomes with a high satisfaction score. No association between the implant material used and the results has been assessed. Conclusion: This study describes the results of orbital floor reconstructions. Despite a variety of materials used and surgical approaches performed, we believe that the transconjunctival approach is the most suitable option with a high satisfaction score.

Purpose: Maxillofacial trauma predominantly affects young adults between 20 and 40 years of age. Although radioprotection is a legal requirement, the significant potential of dose reduction in computed tomography (CT) is still underused in the clinical routine. The objective of this study was to evaluate whether maxillofacial fractures can be reliably detected and classified using ultra-low-dose CT. Materials and Methods: CT images of 123 clinical cases with maxillofacial fractures were classified by two readers using the AOCOIAC software and compared with the corresponding results from post-treatment images. In group 1, consisting of 97 patients with isolated facial trauma, pre-treatment CT images at different dose levels (volumetric computed tomography dose index: ultra-low dose, 2.6 mGy; low dose, <10 mGy; and regular dose, <20 mGy) were compared with post-treatment cone-beam computed tomography (CBCT). In group 2, consisting of 31 patients with complex midface fractures, pre-treatment shock room CT images were compared with post-treatment CT at different dose levels or CBCT. All images were presented in random order and classified by 2 readers blinded to the clinical results. All cases with an unequal classification were re-evaluated. Results: In both groups, ultra-low-dose CT had no clinically relevant effect on fracture classification. Fourteen cases in group 2 showed minor differences in the classification code, which were no longer obvious after comparing the images directly to each other. Conclusion: Ultra-low-dose CT images allowed the correct diagnosis and classification of maxillofacial fractures. These results might lead to a substantial reconsideration of current reference dose levels.

Over 60 cases were enlisted, but only 31 cases among 24 patients were eligible with a minimum follow-up of 1 year and complete medical documents with imaging data. There were 18 boys and 6 girls, and 7 patients had bilateral lesions. The age of the patients ranged from 2 to 20 years(mean:10.5 years). At their first visit, most lesions had a highly characteristic location and radiographic appearance of radiolucent lesion(s) ranging from 1 to 3cm, except for one case of 5.5 cm in the posteromedial comer of distal femoral metaphysis. The margins were generally well-defined, although some were ill-defined. After reviewing our cases from the viewpoint of clinical course and radiographic patterns, we divided these lesions into two types. Type I is the osteolytic lesion excavated into the posteromedial aspect of the distal femur without cortical defect; and type II is the buldged out lesion of the femur with cortical irregularity into the surrounding soft tissues. Both types have distinctive clinical courses. Type I lesions were easy to make a definite diagnosis with plain radiographs alone, but in type II, it was sometimes very difficult to differentiate it from malignant tumors or chronic localized osteomyelitis. For this lesion, Gd-enhanced MRI was the most effective method for differential diagnosis. In this study, biopsy was not necessary to confirm the diagnosis. Clinical symptoms of type I were very minor or even absent. Many of them were accidentally found after minor trauma around the knee joint. Clinical symptoms disappeared far earlier than radiographical lesions. No treatment such as restriction of activity or drugs was necessary. For type II, the clinical symptoms were more accentuated and lasted longer, and it was necessary to restrict the activity for a certain period in many cases. However, all were self-limited.

Purpose: This study aimed to determine new criteria for detecting independent factors with high sensitivity in cases of cervical spine injury. We compared the sensitivity, the specificity, and the false negative predictive value (NPV) of plain radiographs with those of computed tomography for cervical spine injury in patients with minor head injury. Methods: We retrospectively reviewed the cases of 357 patients who underwent both cervical plain radiographs and computer tomography from January 2006, to September 2008. Patients were divided into two groups: the cervical spine injury group and the no cervical spine injury group. New criteria were organized based on variables that had significant differences in the logistic regression test. Results: Among the 357 patients, 78 patients had cervical spine injuries. The average age was $43.9{\pm}15.2$ yrs old, and the male-to-female ratio was 1.90. The most common mechanism of injury was motor vehicle accidents. There was a significant difference in loss of consciousness, Glasgow Coma Scale (GCS)=14, neurologic deficit, posterior neck tenderness, and abnormality of the cervical plain radiographs between the two groups on the logistic regression test. New criteria included the above five variables. If a patient has at least variable, the area under the ROC curve of the new criteria was 0.850, and the sensitivity and the false NPV were 87.2% and 5.2%, respectively. Conclusion: New criteria included loss of consciousness, GCS=14, neurologic deficit, posterior neck tenderness, and abnormality of the cervical plain radiographs. If the patient had at least 1 variable, he or she could have a of cervical spine injury with a sensitivity of 87.2% and a false NPV of 5.2%.

This study was done to define nursing diagnose and to test the validity of the characteristics for patients with cerebrovascular accidents being seen at home by home health care nurses. This study was a descriptive study. The sample consisted of 10 experts(professors and home health care nurses) who had had a variety of experience using nursing diagnoses in clinical practice, and 336 nurse progress notes for 18 patients with cerebrovascular accidents. First, 32 nursing diagnoses were defined by the analysis of 336 nurse progress notes, and ten nursing diagnoses were selected according to a criteria of frequency and four nursing diagnoses from home health care clinical practice. Second, content validity was examined by an expert group which considered the sign / symtoms of the fourteen nursing diagnoses. The instrument used for this was a checklist for sign / symtoms based on the nurse progress notes and literature : Carpenito(1993), Kim Cho Ja et al (1994), Lee Sun Ok et al.(1994), Kim Mae Ja et al. (1992), Seoul University Hospital (1993) , Kim Mi Ja et al. (1991). The data were collected from March 1995 to April 1995. Data were analyzed using Content Validity Incidence where if 80% or more of the expert group agreed, characteristics were defined as a major sign/symtoms, if between 50% and 79% of the expert group agreed with the characteristic it was defined as a minor sign / symtoms. The results of this study are summarized as follows : 1. Thirty-two nursing diagnoses related to patients with cerebrovascular accidents were defined. There was a high frequency for the following : 'Potential for disuse syndrome (61%)', 'Impaired physical mobility(50%)', 'Impaired skin integrity (44.4%)', Potential for aspiration(33.3%)', 'Potential for infection: respiration(33.3%)', 'Self-care deficit : bathing /hygine(27.8%)', 'Ineffective family coping(22.2%)', 'Potential for trauma(22.2%)', 'Alteration in nutrition: less than body requirements(22.2%)'. The following diagnoses were also used in home health care clinical practice : 'Anxiety in family (50%)', 'Caregiver fatigue(27.8%)', 'Ineffective treatment behavior (22.2%)', 'Ineffective Levin tube management and Levin tube feeding(22.2%)'. Fourteen nursing diagnoses were selected. 2. Ten of the nursing diagnoses for patients with cerebrovascular accident were listed as nursing diagnoses by NANDA but four nursing diagnoses were new nursing diagnoses used in home health care clinical practice. 3. Characteristics of the ten Nursing Diagnoses from NANDA were developed from the sign /symtoms in the literature and in the nurse progress notes. These characteristics was verified as major or minor sign / symtoms by the expert group. 4. Characteristics of the four nursing diagnoses used in home health care were not defined by the literature but only by the nurse progress notes and verified as major or minor signs /symtoms by the expert group. On the basis of the findings of this study, the following recommendations are made : 1. Continual study is necessary to identify other signs /symtoms not verified in this study. 2. It is necessary to use verified signs /symtoms in home health care clinical practice. 3. It is necessary to define related factors which define each diagnoses in this study. 4. It is necessary to develop of standardized nursing are plans which include defined signs and symtoms. 5. It is necessary to study the outcomes of the standardized nursing care plans.

Objective : The incidence of head injury has been increasing in the rural area. The author investigated the clinical features and difficulties in care of the acute head-injured patients in this area. Method and Material : The authors performed a retrospective review of radiological data and clinical records in patients with mild to moderate head injury. Cause, type of craniocerebral injury, delayed intracranial lesions, complications, its relation to alcohol abuse, and outcome were analyzed. Results : In total of 68 cases, 20(29.4%) victims were associated with acute alcohol intoxication. Motor vehicle accident was the leading cause of head injury and the most common craniocerebral lesion was basilar skull fracture. Eight(11.8%) patients showed delayed radiological and clinical deterioration and 40(58.8%) were followed-up regularly after discharge. The subdural hygroma was commonly noted in the elderly and alcoholics. Causes of thirty events that resulted in an atypical and difficult neurosurgical practice were as follows : delayed admission, premature discharge against doctor's request, refusal of radiological studies and admission, misunderstanding of disease entity, and unreasonable desire of transfer to tertiary hospitals. Inaccurate initial diagnoses were made by emergency doctors in twenty patients. During the course of treatment, there were a few complications such as alcohol withdrawal, acute otitis media, cerebrospinal fistula, facial weakness, and posttraumatic seizure. Outcome was good in 60(88.2%) patients. Conclusion : Most of minor head trauma patients in this series have shown good results, but we have to consider some possible complications and delayed intracranial lesions in these patients that should be managed with special cautions with various kinds of treatment difficulties.

Only a few cases of anterior longitudinal ligament (ALL) injury related with retropharyngeal hematoma without fracture have previously been reported. The treatment of choice for retropharyngeal hematoma is generally considered to be conservative care, but we believe that early surgery of this pathology would be better in certain situations. Here, we describe two cases with life-threatening large retropharyngeal hematomas related with ALL injuries and operated on at an early stage. Two previously healthy patients visited the emergency room with neck pain and dyspnea after falling. Serious neck swelling was observed and lateral neck X-ray showed severe widening of the prevertebral space. Due to dyspnea progression, emergency endotracheal intubation was performed. Although there was no primary cause of the retropharyngeal hematoma on preoperative examination, ALL tearing was intraoperatively confirmed during early surgery. The in-hospital evolutions of the patients were favorable after surgery. We should bear in mind the possibility of ALL injury and perform early surgery where possible given the earlier convalescence and good prognosis.
