Pneumonectomy on a patient with documented poor pulmonary function indicating a contraindication to surgery can be associated with a high risk of serious postoperative morbidity or mortality. However the usual criterias, on the performance of a pneumonectomy on a high risk patient based on the preoperative assessment of the pulmonary function may not sometimes predict with accuracy the operative outcome in the postoperative period. We recently performed pneumonectomy with good results on a patient with poor pulmonary function that would otherwise have been an absolute contraindication to surgery by usual criteria.

The purpose of this study was undertaken to determine the effects of orthognathic surgery on speech. The hyposis stated herein is that functional behaviors of the dentofacial complex, such as speech production, may be adversely affected by deviations of a structural nature(especially, Class III malocclusion). Twenty adults with Class III malocclusion(13 female and 7 male) were studied preoperative, immediate postoperative and either 6 or 12 months postoperative lateral cephalograms. They had mandibular prognathism and had undergone mandible setback operation. The position of tongue, soft palate(Uvula), hyoid bone, respiratory track width, and pharyngeal depth were assessed on lateral cephalograms with 23 cephalometric variables, ANOVA, Paired t-tests and Pearson's product-moment correlation coefficient tests were used to evalute the operative changes in all cephalometric parameters. A experienced speech and language pathologists performed narrow phonetic transcriptions of tape-recorded words and sentences produced by each of the ninth patients and the recording tapes were analyzed by phonetic computer program(Computerized Speech Lab(CSL) Model 4300BI(U.S.A.)) These judges also recorded their ratings of each patient's overall consonants, hypernasality, hyponasality, and articulation proficiency. The results obtained are as follows; 1. There were significant changes in distance of posterior pharyngeal wall to tongue (TI-TW2, TS-TW3) after the surgery at 6 months postoperatively(each p<0.01 p<0.05). 2. The posterior tongue point(TI, TS, PPT) moved posteriorly after surgery and remained to its changed position at 6 months postoperatively(p<0.05). The displacement of tongue was correlated with the movement of mandibular setback amount(p<0.05). The hyoid bone moved posteriorly superiorly after immediate postoperative period. There was significant changes in hyoid bone movement after immediated postoperative period(p<0.05), but returned to its original position during the follow-up period(p>0.05) 3. The soft palate was displaced posteriorly superiorly after immediated operative period and remained to its changed position at 6 months postoperatively(p<0.05). ANS-PNS-SPT angle increasing, PPU-PPPo distance narrowing was showed after surgery, and remained its appearance 6 months postoperatively(p<0.05). 4. There were significant changes in formant value and squre diagram of vowel sound after the orthognathic surgery and the follow-up period. There were significant changes in /ㅅ/sound and posterior tongue sound. 5. The posterior movement of tongue and the posteriosuperior movement of soft palate was correlated with mandibular setback amount after orthognathic surgery. On the vowel squre diagram, the author found that the place of articulation after operation moved downward, backward, upward. 6. In assessing speech abnormalities, dental occlusion should be considered as a contributing factor. The vast majority of subjects with preoperative misarticulations eliminated or reduced their errors following orthognathic surgery. There was significant difference in speech impovement between pre- and postoperation.

Pediatric laparoscopic splenectomy has been gradually accepted as the surgical management of a various splenic disorders, particularly in hematologic diseases. We report our experience with 16 patients who underwent this procedure because of hematologic disorders during the past 3 and a half years at the Department of Surgery, St. Mary's Hospital, the Catholic University Medical College. The mean age was 10 years(range 6-16 years) and the mean spleen weight was 210 gm(range 85-500 g). The indication for splenectomy were hereditary spherocytosis(6 cases), idiopathic thrombocytopenic purpura(8 cases), autoimmune hemolytic anemia(1 case), and idiopathic splenomegaly(1 case). All splenectomies were performed safely with mean estimated blood loss of 233 ml. Mean operative time and mean postoperative hospital stay were 157 min and 4.5 days, respectively. Postoperative pain, medication was needed in 3 cases, just one injection in immediate postoperative period. Diet was started on the second or third postoperative day. In conclusion, laparoscopic splenectomy in pediatric patients is a safe procedure, offering a small of abdominal scar, much less pain, a shorter hospital stay and car the lower postoperative morbidity.

Objective : The goal of treatment for spinal cord ependymoma is complete removal without postoperative neurological deficit. The authors analyzed the surgical results and factors influencing the postoperative prognosis. Methods : Fifty-one cases of primary spinal cord ependymoma, surgically treated between 1979 and 2003, were retrospectively analyzed. The mean follow-up period was 44 months. Results : Gross total removal was achieved in 42 patients and incomplete removal in nine. The proportion of complete surgical removals was influenced by tumor location and histology. Disease progression was observed in five cases [9.8%], the mean progression free interval after surgical removal was 48 months and the 5-year progression free rate was 68%. Disease progression was found in none of the 42 cases who underwent complete removal, and in 5 of 9 cases who hadincomplete removal group [P<0.001]. Statistically significant disease-progression factors by multivariate analysis were the surgical extent of removal [P=0.012]. preoperative functional status [P=0.032] the presence of intratumoral cysts [P=0.007] and postoperative radiation therapy [P=0042]. Of those patients who underwent incomplete removal, radiation therapy was found to significantly improve the clinical result [P=0042]. Conclusion : In the surgical treatment of spinal cord ependymoma, preoperative functional status, the presence of intratumoral cysts, the extent of removal, and postoperative radiation therapy were found to be significant prognostic factors of postoperative outcome.

Objective : To compare two different methods of rigid fixation in postoperative stability after mandibular setback. Material and Methods : 28 patients with Class III malocclusion were treated by bilateral sagittal split ramus osteotomy(BSSRO) and mandibular setback were selected for this study. Group A(n=14) had the bone segments fixed with monocortical miniplate on the lateral side of the mandibular body and Group B(n=14) had three noncompressive bicortical screw inserted at the genial area through a transcutaneous approach. Cephalograms were taken preoperatively, postoperatively within 1 weeks and at a follow-up period (mean 8.9 months after surgery) and the amount of setback and postoperative change were measured. Results : Postoperative relapse between two groups was minimal in setback of the mandible. Statistical analysis showed no significant difference in postoperative relapse. Conclusion : This study suggests that both methods of skeletal fixation investigated give comparable postoperative stability and their use in mandibular setback appears to be a fairly stable clinical procedure .

Objective : Frameless stereotactic aspiration of a hematoma can be the one of the treatment options for spontaneous intracerebral hemorrhage in the basal ganglia. Postoperative hematoma enlargement, however, can be a serious complication of intracranial surgery that frequently results in severe neurological deficit and even death. Therefore, it is important to identify the risk factors of postoperative hematoma growth. Methods : During a 13-year period, 101 patients underwent minimally invasive frameless stereotactic aspiration for basal ganglia hematoma. Patients were classified into two groups according to whether or not they had postoperative hematoma enlargement in a computed tomography scan. Baseline demographic data and several risk factors, such as hypertension, preoperative hematoma growth, antiplatelet medication, presence of concomitant intraventricular hemorrhage (IVH), were analysed via a univariate statistical study. Results : Nine of 101 patients (8.9%) showed hematoma enlargement after frameless stereotactic aspiration. Among the various risk factors, concomitant IVH and antiplatelet medication were found to be significantly associated with postoperative enlargement of hematomas. Conclusion : In conclusion, our study revealed that aspirin use and concomitant IVH are factors associated with hematoma enlargement subsequent to frameless stereotactic aspiration for basal ganglia hematoma.

Background: Pregabalin has been studied as a single or multimodal analgesic drug for postoperative pain management in different types of surgeries. We evaluated the analgesic effect of 150 mg of pregabalin in resolving post-gastrectomy pain. Methods: Forty-four patients were randomized into two groups: a pregabalin group that received oral pregabalin (150 mg) 2 h before anesthetic induction, and a control group that received placebo tablets at the same time. Data on postoperative pain intensity (visual analog scale [VAS], at 30 min, 2 h, 4 h, and 24 h), consumption of fentanyl in patient-controlled analgesia (PCA), and the proportion of patients requiring rescue analgesics at different time intervals (0-2 h, 2-4 h, and 4-24 h) were collected during the 24 h postoperative period. Results: The VAS scores did not show significant differences at any time point and consumption of fentanyl in PCA and the proportion of patients requiring rescue analgesics did not differ between the two groups. The groups did not differ in the occurrence of dizziness, sedation, and dry mouth. Conclusion: A preoperative 150 mg dose of pregabalin exerts no effect on acute pain after gastrectomy.

Objectives: This study aimed to compare the postoperative pain and clinical performance after partial pulpotomy by using ProRoot MTA and Endocem MTA. Materials and Methods: Twenty-eight teeth requiring partial pulpotomy due to deep dental caries or traumatic injury were included in this study. After 2mm removal of exposed pulp and bleeding control, the ProRoot MTA or Endocem MTA was randomly adjusted to the exposed site. 1, 2, 4, and 12 weeks after the final restoration, the patients were recalled to check the postoperative pain or another unfavorable signs. Pearson's chi-square test was used for statistical analysis to evaluate any differences among tested materials. Results: 3 of 28 teeth showed postoperative pain and cold positive during follow-up period (10.7%). There were no statistically differences in pain occurrence between two tested materials (P > 0.05). Conclusions: In the limitations of this study, partial pulpotomy by using Endocem MTA showed the advantages of short setting time and lower postoperative pain incidence, allowing one visit treatment.

Purpose : To evaluate the role of postoperative radiotherapy in the management of primary or recurrent intracranial meningiomas. Methods and Materials : A retrospective review of 34 intracranial meningioma patients referred to the Yonsei Cancer Center for postoperative radiotherapy between 1981 and 1990 was undertaken. Of the 34 patients, 24 patients received elective postoperative radiotherapy after total or subtotal resection(Group 1), and 10 patients received postoperative radiotherapy as a salvage treatment for recurrent tumors(Group 2). Ten patients received postoperative radiotherapy after total resection, and twenty-four after subtotal resection. Ten patients who had total tumor resection were referred for radiotherapy either because of angioblastic or malignant histologic type(4 patients in Group 1) or because of recurrent disease after initial surgery(6 patients in Group 2). Radiation dose of 50-56 Gy was delivered over a period of 5-5.5 weeks using 4MV LINAC or Co-60 teletherapy unit. Results : Overall actuarial progression free survival(PFS) at 5 years was $80\%$. Survival was most likely affected by histologic subtypes. Five year PFS rate was $52\%$ for benign angioblastic histology as compared with $100\%$ for classic benign histology. For malignant meningiomas, 5 year PFS rate was $44\%$. The recurrence rates of classic, angioblastic, and malignant type were $5\%(1/21),\;80\%(4/5)$, and $50\%(4/8)$, respectively. The duration between salvage post-operative radiotherapy and recurrence was longer than the duration between initial surgery and recurrence in the patients of group 2 with angioblastic or malignant histology. Conclusion . Postoperative radiotherapy of primary or recurrent intracranial meningiomas appears to be effective modality, especially in the patients with classic meningiomas. In angioblastic or malignant histologies, a more effective approach seems to be needed for decreasing recurrence rate.
