Reconstruction of partial ear defect to approximate the opposite normal ear is actually very difficult. Because the patterns of partial ear defect (site, shape and size of defect) are extremely variable, the operative method on each case should be changed. In an effort to overcome these problems, many reconstructive methods have been reported so far. We experienced 11 cases of partial ear defect from September, 1995 to August, 1996 and different reconstructive methods were applied In this study, the most common cause of partial ear defect was trauma (9 cases) and the most common site was middle part of ear helix. The defects were varying from 1x2 cm to 1.5x5 cm in size. The methods that has been used for reconstruction of ear defect include direct closure, helical chondrocutaneous advancement flap, Dieffenbach's method, retroauricular flap, tubed bipedicled flap and so on. We could get to know the merits and demerits of each method through this follow up study. So authors obtained the several basic conclusions about the merits and demerits of each method and standard of method selection in various patterns of ear defects. From analysis of the cases with review of literature, the our conclusions are as follows. 1. If the size of de(tract is small and the patient does not want to have two times of operation, direct closure can be done with good results. 2. If the defect exists on ear auricle confuted to helix and if there are no or small amount of associated cartilage defect, tubued bipedicled flap seems to be proper. 3. With the ear auricle defect confined to helix, especially helix of upper ear auricle, helical chondrocutaneous advancement flap can brought tile best result, though it has disadvantage of being decreased in its size 4. If there are extensive defect on ear auricle extending over scapha and antihelix, retroauricular flap can be done with good results. 5. In the ear auricle defect acompanying considerably large cartilage loss, Dieffenbach's method is thought to be proper.

Hurthle cell tumors are an infrequent neoplasm of the thyroid gland in adults. Hurthle cell tumors represent 4. 5% to 10% of all primary thyroid epithelial neoplasms in the foreign literature. It has been known as Hurthle cell tumor since Ewing was the first to use this term in 1928. Tumor occurring in an infant was described by Symmers(1941) and Morrow(1945). The authors experienced a case of congenital Hurthle cell tumor of the thyroid gland in a 2 months old boy. He was admitted to the pediatric surgical department because of a growing mass in the neck since birth. Ultrasonogram showed a huge lobulated homogenous solid mass with medium level echogenicity in the region of the thyroid gland. Subtotal thyroidectomy of right lobe and total thyroidectomy of left lobe were done. The specimen measures 2x3x1.5 cm and 7x3x3 cm, respectively. It was an encapsulated, yellow gray firm and solid mass. The cut surface was smooth, glistening and homogenous. Microscopicully, the tumor was composed of tightly packed regular follicles lined by polyhedral, cuboidal, large cells with a granular acidophilic cytoplasms. The nuclei are vesicular, usually only a little bit larger than those of normal thyroid cells.

Background: Esmolol is rapid hydrolyzed by plasma esterase but may inhibit plasma cholinesterase activity based on its structure. This study was designed to evaluate the interactions between esmolol and succinylcholine or mivacurium which are metabolized by plasma cholinesterase and to determine the inhibitory effect of esmolol on human plasma cholinesterase. Methods: Neuromuscular effects of succinylcholine (1.0 mg/kg) and mivacurium (0.15 mg/kg) with or without esmolol (0.5 mg/kg or 1.0 mg/kg) were compared in 57 adult patients (ASA class I) during O2-N2O-isoflurane anesthesia. Neuromuscular block was monitored by recording the compound electromyogram of the hypothenar muscle resulting from supramaximal train of four stimuli applied to the ulnar nerve. Also plasma cholinesterase activity was measured before and 5, 10 minutes after injection of esmolol. Results: Time from injection to onset of over 95% block, clinical duration from injection to 25% recovery of control twitch, and recovery index defined as from 25% to 75% twitch recovery of succinylcholine or mivacurium were not altered by pretreatment of esmolol. Plasma cholinesterase activity was not decreased after injection of esmolol 0.5 mg/kg, but decreased by 5% after injection of 1.0 mg/kg (p<0.05). Conclusions: It is unlikely that neuromuscular blocking effects of succinylcholine and mivacurium are prolonged by administration of clinical doses of esmolol (0.5~1.0 mg/kg) due to inhibition of plasma cholinesterase activity in human.

Vecuronium induced intense neuromuscular blockade was evaluated in 40 USA class l, ll adult patients using the post tetanic count (PTC) and train-of-four(TOF) methods. All patients were anesthetized with thiopental sodium, nitrous oxide(50%), and enflurane(1~2%). Neuromuscular monitoring commended immediately after administration of thiopental sodium. The ulnar nerve was stimulated using surface electrodes and the mechanical response of the adductor policis muscle recorded using the Acclograph, neuromuscular transmission monitor. TOF nerve stimulation was used every 15s. After supramaximal stimulation was achieved a bolus of vecuronium 0.1mg/kg was injected intravenously. The traches was intubated when TOF response was depressed to 95% or above to control twitch height and the lungs ventilated with a tidal volume of 10ml/kg and a rate of 14 b.p.m. The patients were allocated randomly to two groups of 20 patients each. Patients in control group were allowed to recover TOF response spontaneously, and in PTC group were applied tetanic stimulation(50Hz for 5s) at 7 minutes intervals during no TOF response. In PTC group, the tetanic stimulation was preceded by a 30s period of 1Hz stimulation on each occasion, which was continued after the 3s pause. Duration of no TOF response in each group, and relationship between first post tetanic twitch height of PTC and time to first reaction to TOF nerve stimulation in PTC group were measured. In the results, duration of no TOF response was shortened by tetanic stimulation(p<0.01). There was a close inverse correlation between first post tetanic twitch height or PTC and time to first reaction to TOF nerve stimulation (p<0.01). It was concluded that PTC method appeared to be a valuable supplement to TOF nerve stimulation in assessment and trend for vecuronium induced intense neuromusclular blockade.
