Substantial confusion exists regarding the nomenclature of benign vocal fold lesions (BVFL), because there were no pathologically diagnostic findings and deep understanding of pathogenesis in the past. There is no consensus on specific labels for BVFL, nor are the most commonly used terms defined. There is a need for a defined nomenclature for the purpose of improving communication among clinicians and with patients. Furthermore, precise definitions of BVFL will facilitate clinical research of voice disorders and may lead to a better understanding of outcomes for BVFL treatment. Laryngoscope, stroboscope, voice evaluation are used to diagnose BVFL. The objective of this review article was to develop a new paradigm of BVFL nomenclature using patient's history, stroboscope, voice therapy results, and operative findings. Furthermore, precise definitions of BVFL will facilitate clinical research of voice disorders and may lead to a better understanding of outcomes for BVFL treatment.

A patient was 29 year old house wife who was admitted to the Yonsei University Medical Center on 6 th of Nov., in 1970, with chief complaints of complete loss of bilateral visual acuity, generalized weakness, frequent palpitations, claudication of masseter muscles and intermittent fainting. These symptoms were developed 5 years prior to admission. Physical finding on admission revealed complete loss of bilateral visual acuity, absence of both radial and carotid pulse, but there was good femoral and popliteal pulse. She couldn't open her mouth as she desired and had weakness of mastication. Radiological findings of plane chest PA were not significant. Aortogram(Cineangiogram) showed non-visualization of both carotid and subclavian arteries. It showed only innominate and interal mammary artery preoperatively. The operative findings were as follows: There were complete obliterative changes in both common carotid and subclavian arteries, and periarteritis in the innominate artery. Tube Dacron Prosthesis Bypass with V-arm between innominate artery and both common carotid arteries was performed after thromboendarterectomy. Histopathological finding of the thromboend arterectomy specimen was compatible with pulseless disease, which showed marked fibrous thickening of intima and a diffuse inflammatory cell infiltration of the whole layers. Her postopererative course was uneventful. Follow up aortogram(Cineangiogram) was taken on 11th postoperative day, which revealed both common carotid arteries patent. Her preoperative Subjective symtoms disappeared remarkably, such as her visual acuity improved much, fainting and vertigo disappeared completely and she can go to bath room without difficulty and help. Another patient was 34 year old house wife who was admitted on August, 1964 with chief complaints of frequent fainting and progresive visual loss. She was operated only thromboendarterectomy of both common carotid arteries. Postoperative course was smooth and subjective symptoms were disappeared.

To prevent recurrence of spontaneous pneumothorax, 23 patients were operated through median sternotomy for simultaneous resection of bilateral bullae, And 27 patients with spontaneous pneumothorax were treated with unilateral thoracotomy, We studied the number, duration and sites of recurrence including findings of CT scan, as well as comparing the both operated group. The incidence of spontaneous pneumothorax was 88% in patients with the ages between 16 to 35 Forty one patients[82%] were operated with the indication of recurrent pne-umpthorax. The number of pneumothorax attack was 2.34 per patient with recurrent pneumothorax. The 87.8% of recurrence was occured within 6 months from last attack. Ips-ilateral recurrnet pneumothorax was 56.1% and contallateral involve was 43.9%. The bilaterality of visible bullae was 90.9% in the findings of chest CT scan and 91.3% in the operative finding. The sensitivity and accuracy for bulla detection with chest CT were 92.6%, respectively. Exclude one case of complicated median sternotomy infection, the postoperative hospital stay was shorter in median sternotomy approached group[P<0.05]. In conclusion, the bullous lesions of the lung have tendency of bilaterality so that median sternotomy for simultaneous resection of bilateral bullae should be considered in patients with contralateral visible bullae with chest CT.

Purpose: Recent developments in minimally invasive techniques have the potential to reduce surgical morbidity, promote patient recovery, accelerate surgical procedures, and thus improve cost-effectiveness in case management. In this study, we compared the treatment efficacy and results of supraorbital keyhole approach (SOKA) with those of conventional unilateral frontal craniotomy (CUFC) for traumatic intracerebral hemorrhage (TICH) in the frontal lobe. Methods: We analyzed the data of 38 patients who underwent CUFC (n=30) and SOKA (n=8) and retrospectively reviewed their medical records and radiological findings. Furthermore, we tried to identify the best surgical method for such lesions by including patients who underwent burr hole aspiration and drainage (BHAD) (n=9) under local anesthesia due to various circumstances. Results: The difference in the initial Glasgow coma scale score, operative time, and length of hospitalization between the CUFC and SOKA were statistically significant. All radiological features between the two groups including associated skull fracture, amount of pre- and postoperative hematoma, percentage of complete hematoma removal, pre- and postoperative midline shifting of the hematoma, and development of postoperative delayed hematoma were not statistically significant. Our experience of 46 patients with TICH in the frontal lobe with any of the three different surgical methods including BHAD enabled us to obtain valuable findings. Conclusions: Although it is difficult to insist that one particular approach is more useful than the other, we are confident that SOKA will have more advantages over CUFC in carefully selected patients with frontal TICH depending on the surgical experience of a neurosurgeon.

Intraoperative cytologic examination of intracranial tumors using crush preparation provides useful information in operative decision making. The diminutive nature of many biopsy specimens, particularly those obtained by stereotactic neurosurgical procedures emphasizes the importance of combining the cytologic smear method with conventional frozen section interpretation. The great advantage of the cytologic smear method resides in its suitability for the study of minute fragments of tissue, allowing retention of the majority of the specimen for optimal processing. We present the cytologic features of 3 cases of intracranial germ cell tumors(2 germinomas and 1 endodermal sinus tumor), using crush preparation during intraoperative diagnosis and compare them with histologic findings. The cytologic features of the germ cell tumors were similar to those of the respective gonadal counterparts. The cytologic differential diagnosis of both types of germ cell tumors is described.

The purpose of this study was to aid in diagnosis of salivary gland disease by comparing the sialogram with the scintigram. In this study, 47 patients (52 glands) who had taken the sialography and the scintigraphy were examined. The result of two methods was compared with the clinical and operative diagnosis. The following results are obtained. 1. In inflammatory diseases of the salivary gland, the scintigraphy can be a valuable substitution for a sialography. 2. In inflammatory diseases of the salivary gland, we can get more informations in case of the combined use of the sialography and the scintigraphy. 3. In tumorous lesion of the salivary gland, the sialography is superior to the scintigraphy. But both methods are less valuable in diagnosing the extraglandular tumors.

Purpose: This study aimed to explore nursing students' experiences of observing surgeries in the operating room. Methods: The data were collected through written scripts of nursing students who participated in the operating room practice. Data were analyzed via qualitative content analysis. Results: Five themes emerged from the data: 'preparing with the thrilled hearts toward unknown area', 'drawing back in front of the mirror of realities', 'becoming an audience at a lifesaving orchestra', 'reaching a tipping point of knowing', and 'redrawing the trajectory of dream to be a nurse'. Conclusion: This study will prove helpful in describing their needs for systemic and emotional support. Findings indicated that major contributions of surgical observations to nursing students are more integrated understandings of nursing and the determinations of their career preferences.

A modified procedure for the operative management of the corrected transposition of the great arteries with ventricular septal defect and pulmonary stenosis or atresia was performed in 4 patients. (age ; 18 months-9 years). The operation consists of a venous switch procedure (Senning), intraventricular baffling directing the blood flow from the morphologic left ventricle into the aorta via ventricular septal defect through the right ventriculotomy, and insertion of valved conduit between the morphologic right ventricle and the pulmonary artery. All the four patients had large non-restrictive ventriular septal defects and no evidence of significant mitral valve regurgitation. Both ventricles were well-developed. Three cases had pulmonary atresia, and the remainder had severe subpulmonic stenosis. Postperatively, all patients showed no findings of systemic or pulmonary venous obstruction withnormal sinus rhythm. One patient died of sepsis due to infection by Methicillin-resistant S. aureus on the thirteenth postoperative day. Follow-up is done on the survivors, and all of them are dong well with regular sinus rhythm, with their functional class I or II at 2 to 8 months after the operation.

Bochdalek hernia in adult is relatively uncommon. We experienced a surgical case of Bochdalek hernia in a 29 year old housewife. She was admitted via E-R due to left chest pain and nausea for 1 months. 5 days before admission, she had Cesarean section on private hospital. After delivery, nausea and exertional dyspnea were aggravated. On admission, chest PA showed herniated stomach, colon, small intestine on left thorax. She was diagnosed of diaphragmatic hernia and operated. Operative findings were as follows: 1. hypoplastic: lower lobe of left lung, 2. stomach, colon, small intestine, spleen were herniated, 3. the defect was located on posterolateral portion of diaphragm, measuring 10 x 8 cm in size. Herniated intestines were reduced and diaphragmatic defect was repaired as interrupted sutures with 2-0 Mersilene. Postoperative courses were uneventful and the patient was discharged on POD 10th.

During a eight month period[from December, 1988 to July, 1989], a series of 35 adults undergoing redo-valve replacement or coronary artery bypass grafting was selected to an autotransfusion group[n=10] or a control group[n=25]. The Cell Saver System[Haemonetics Corp., Graintree, Mass] was employed for autotransfusion. With this system, all blood shed in the operative field before and after cardiopulmonary bypass and remained in cardiotomy reservoir after cardiopulmonary bypass was aspirated by means of a locally heparinized collecting system. After the salvaged blood was centrifuged, the resulting red cell concentrate subsequently reinfused. The patients receiving autologous blood required significantly less banked homologous blood than their controls[3213k1020 ml and 506051931 ml, respectively: p=0.001] There were no clinical infections in the autotransfusion group, although 40% of the cultures of processed blood were positive. And there was no apparent intergroup difference of the clinical and the hematologic and hemostatic laboratory findings. We conclude that autotransfusion using cell saver is effective for saving the homologous blood transfusion in cardiac surgery.
