As the use of free tissue reconstruction becomes more routine, attention is being focused not only on flap survival, but also on functional refinements in these flaps. One of the more important aspects of improving the outcome of these reconstruction may relate to the return of sensation. The anterolateral thigh free flap is based on the descending branch of the lateral circumflex femoral artery. This fasciocutaneous flap is indicated whenever a relatively thin flap is required in reconstruction. A neurosensory flap can be employed based on the anterior branched of the lateral femoral cutaneous nerve of the thigh. Since 1996, 15 patients with soft tissue defect on various regious were treated by using the anterolateral thigh sensate free falp. All flaps survived without total loss. Anastomosis of the sensible nerve on the recipient site with the anterior branch of the lateral femoral cutaneous nerve of the thigh was performed. All patients showed recovery of sensation in the anterolateral thigh sensate free falp beginning between the 4th and 6th month postoperatively. Follow-up periods ranged from 8 to 34 months and the results of sensory recovery were satisfactory. Therefore, resensitization of an anterolateral thigh free flap should be attempted by a nerve anastomosis in this transplant. The longterm success in this study suggests the benefits of microsurgical neurotization in free tissue transplantation.

PURPOSE: This study examined the efficacy of ureteroscopic stone manipulation with comparing the success rates and complications rates. MATERIALS AND METHODS: The manipulation of calculi can be done under the direct vision of ureteroscope using dormia baskets with increasing safety and efficacy. The results of ureteroscopic removal of stones were reviewed in 636 cases. From January 1992 to October 1997, 636 patients underwent ureteroscopic removal of stones. RESULTS: There were 236 female and 400 male patients between 16 and 75 years old. The success rates of ureteroscopic removal of stones were related to location of the calculus: 95.8% in lower ureter, 87.7% in mid ureter and 90% in upper ureter(overall success rate was 95%). 35 cases(5.8%) of complication occurred in 604 cases of success: Severe ureteral mucosal injury in 25 patients, gross hematuria(>48hours) in 4 patients, ureteral mucosal prolapse in 3 patients, flank pain(>48hours) in 2 patients, ureteral perforation in 1 patient. CONCLUSIONS: Ureteroscopic removal of stones can be successful and safe treatment modality for lower urethral stones, especially with plentiful experience and good surgical skill.

To compare the effects of atracurium, 0.75 mg/kg, on the mean arterial pressures, heart rates and plasma histamine levels under 2%-enflurane inhalation with mask, 24 patients were allocated randomly into two groups; one(Group I, n=12) which atracurium was administered with rapid bolus injection for 5 seconds and the other(Group II, n=12) with the slow injection for 75 seconds. In both groups, there are the most significant decreases and the recovery in mean arterial pressure 1~2 min and 5 min after atracurium, respectively, Group I showed a significant decrease of mean arterial pressure about 10% more than Group II. In heart rate, there are the significant decreases gradually to 87~88% of control 5 min after atracurium in both graups except the only significant increase(104%) 1 min after atracurium in Group I. And Group I showed a significant increase(200%) in plasma histamine concentration (p< 0.05) 2 min after injection than before, but Group II did no significant change. In conclusion, the slow injection of atracurium over 75s during induction of anesthesia can attenuate the histamine-induced cardiovascular response.

For many years, interest in cardiac function has primarily centered around the systolic pump performance of the left ventricle. it is now recognized, however, that diastolic abnormalities may be just as important in the pathophysiology of certain cardiac disease states. To examine the left ventricular abnormalities (especially diastolic events) in hypertension, diastolic and systolic time intervals were measured from simultaneous high-speed recordings of a phonocardiogram, ECGs, apexcardiogram, echocardiogram and external carotid pulse in 35 hypertensive patients and were compared with those in 15 normal subjects. The hypertensive patients showed significantly prolonged preejection period (PEP) and shortened ejection time (ET), compared to those in normal control subjects (p<0.005, p<0.05 respectively). The PEP/ET ratio too was different from the control subjects in hypertensive patients (0.335+/-0.050 vs 0.422+/-0.666; p<0.005). The isovolumic relaxation time (IVRT) was increased to 81.3+/-15.0 msec, which was significantly longer (p<0.005) than in normal subjects (56.7+/-10.7 msec), in patients with hypertension. The active filling period (AFP) was also prolonged. In patients with hypertension there was no significant difference in rapid filling period and slow filling period compared with those in normal subjects. It is likely that in hypertensive patients the alterations of diastolic time intervals, reflecting disorders in elasticity and compliance, may occur in conjunction with abnormal systolic events.

The anatomy of oral cavity in Down syndrome is characterized by hypotonic macroglossia, small oral cavity, and narrow palate with high-arch shape. Because of such characteristics, patients show difficulty in articulation, resonance and phonation. They also suffer from respiratory difficulty due to narrow upper respiratory tract which is exaggerated by hypertrophied tonsil and adenoid. So far we operated on 100 children with Down syndrome for partial glossectomy in average volume of 4.6 cc. We analyzed the results by means of questionnaires and speech test with multi-speech model 3700 program before and after the operation. After partial glossectomy, we observed that they could close their lips comfortably, and it can mitigate the stigma of Down syndrome. We could also observe the improvement in voice quality, pitch, resonance and articulation. Through paired t-test using SAS, we analyzed value of F1, F2-F1, and changes of fundamental frequency(Fo). After partial glossectomy, anteriorly positioned tongue of Down patients became significantly smaller in size and be located posteriorly.
