From May 1988 to January 1997 authors had experienced 13 cases of recurred blepharoptosis. Previous operative procedures were frontalis muscle suspension in 10 cases and levator resection in 3 cases. Follow up period ranged from 11 months to 9 years. We have treated recurred blepharoptosis using frontalis myofascial flap, orbicularis oculi muscle flap and levator resection in accordance with the postoperative levator function and degree of ptosis of patient and considering previous operative technique. The results were that 12 patients have gained the levator excursion over 7 mm and reduced the height difference between both palpebral fissures less than 2 mm after reoperation (good in 6 cases and satisfactory in 6 cases). From these results we might conclude that the frontalis myofascial flap technique is a good secondary blepharoptosis operation for patient with less than 2 mm of levator function, orbicularis oculimuscle flap technique with 2-4 mm of levator function, levator resection with over than 4 mm of levator function. The expert technique and experience are also important factor for the treatment of recurred blepharoptosis.

It is difficult to treat the complete cleft lip because of wide cleft and malaligned alveolar process, outward rotation of greater(medial) alveolar segment, and severe nasal deformity. Lip adhesion without presurgical orthopedic appliance was performed on 8 consecutive infants with unilateral complete cleft of the primary palate before denfinitive lip repair with Millard I procedure. Among 8 patients, 6 patients had complete unilateral cleft lip with alveolar cleft only and 2 patients were accompanied with complete cleft palate. All patients had more than a 10-mm-wide lip cleft with alveolar arch discrepancy. Lip adhesions were performed at 1-2 months of age and definitive repair was done at 5-6 months of age. Lip adhesions were performed by Randall's method and cheiloplasty was done by Millard I technique. Satisfactory results of lip and nose were obtained aesthetically in 8 cases after an average follow-up of 32 months. The vertical height of the medial and lateral lip segment were a symmetric appearance, while the vermilion tubercle, philtrum, and Cupid's bow were natural. Disadvantages included increased operating time and the sacrifice of same-lip tissue. In conclusion, preliminary lip adhesion can have better functional, esthetic and emotional results since the disadvantages are minor compared to the advantages.

During the period from May to October 1969, the authors carried out a series of tests with the aim to ascertain the present status of susceptibility of adult cockraoches to various insecticides. The tests on the susceptibility of cockroaches to dieldrin, D.D.V.P., Diazinon; Dibrom, Malathion and lindane were performed with the topical application and the residual film methods under the conditions of 26 degrees C and 80% of relative humidity. The insects tested were collected from Seoul City and were reared at the laboratory. Some of the important results so far obtained can be summarized as follows: The median lethal doses (LD(50)) of the five insecticides against female adult cockroaches were: 0.4 ug/roach or 4.02 ug/body weight (gm) by Dieldrin, 0.29/roach or 2.88 ug/body weight (gm) by D.D.V.P., 0.29 ug/roach or 2.96 ug/body weight (gm) by Diazinon, 0.54 ug/roach or 5.37 ug/body weight (gm) by Dibrom, and 2.96 ug/roach or 29.60 ug/body weight (gm) by Malathion. And those against male adult cockroaches were: 0.18 ug/roach or 3.29 ug/body weight (gm) by Dieldrin, 0.27 ug/roach or 4.89 ug/body weight (gm) by D.D.V.P., 0.16 ug/roach or 2.91 ug/body weight (gm) by Diazinon, 0.49 ug/roach or 8.97 ug/body weight (gm) by Dibrom, and 1.32 ug/roach or 24.19 ug/body weight (gm) by Malathion. The level of susceptibility of adult cockroaches to the insecticides tested was 1.0-1.6 times higher as compared with the results obtained on the Japanese Takashi strain. The median knockdown times (LT(50)) of the female adult cockroaches by insectcides at 1% concentration of 3 mg per square centimetre were 1.82 hours by Malathion, 1.36 hours by Diazinon, 0.56 hours by Lindane, 0.50 hours by Dibrom, and 2.56 hours by D.D.V.P. A marked difference was seen to exist between the males and the females. The female cockroaches were more resistant than the male to Dieldrin, Diazinon and Malathion.

Paraneoplastic pemphigus is a distinct and rare autoimmune disease characterized by extensive and painful mucosal ulcerations and polymorphic desquamated skin lesions in the setting of an underlying neoplasm, typically of lymphoreticular origin. Thus difficulties in the management of anesthesia can be expected. A 66-years-old man was scheduled for removal of intraabdominal sarcoma associated with paraneoplastic pemphigus. Physical examination showed multiple erythematous bullae, crusts, plaques and target-like lesions on the whole body and desquamated erythematous skin lesions on the back and extremities. In the operating room, his right femoral artery was cannulated with a 20 G, 12.7 cm CVP catheter and left femoral and subclavian veins with 14 G, 20 cm CVP catheters, respectively. After application of 4 % lidocaine spray, his oropharynx and supraglottic area were evaluated under direct laryngoscopy and revealed multiple ulcerations on oral mucosa, but no distinct lesion on supraglottic area. Anesthesia was induced by rapid-sequence method with fentanyl, thiopental sodium and succinylcholine followed by endotracheal intubation. The endotracheal tube was held by a roll gauze around the neck and its cuff was minimally inflated to avoid overpressure against his tracheal wall. After the end of surgery, his oral cavity was suctioned with no remarkable bleeding, and tracheal wall including cuff-contacted area was evaluated under fiberoptic bronchoscopy, revealed intact wall without any bulla or ulceration. The patient was transferred to intensive care unit for proper postoperative management after extubation of endotracheal tube.

Endoscopic technique have become very popular in plastic and reconstructive surgery. They have provided advantages over previously closed techniques by minimizing scars, soft tissue manipulation and access with excellent visualization and magnification. More than twenty cases of facial bone surgery were performed over the past 3 years by endoscopic assistance. Our series consist of 3 cases of frontal bone contouring, 1 zygoma contouring, 3 fracture of zygoma, 9 fracture of orbit, 4 rhinoplasty for deviated nose. To accomplish this technique, a rigid 4 mm, 30 degree down angled endoscope was used. The frontal bone or zygomatic arch is approached endoscopically through two or three small incisions on the temporoparietal scalp. All endoscopic instrument are then manipulated through these incisions. The approach for zygoma complex, maxilla and mandible needs intraoral incision. Recontouring by a power bur and osteotomy using a small saw are done with endoscopic visual assistance. Rigid fixation requires an additional small incision over the plate for trocar method. The other technique was same with routine standard rhinoplasty procedures. The duration of follow-up ranged 3 months to 27 months. The postoperative course were satisfactory with fewer complication than conventional technique. The extra-time need for the endoscopic procedures was about 1 hour Endoscopically assisted facial bone recontouring, osteotomy and plate fixation can be performed with adequate visualization and direct manipulation of all facial bone. Complications usually associated with extensive incisions and pool visualization may be avoided. This technique may prove to be ideal for aesthetic surgery for facia skeleton with smaller scars and less morbidity.

10.Central Lucency of Pelvic Phleboliths: Comparison of Plain Radiographs and Noncontrast Helical CT.
Journal of the Korean Radiological Society 2000;43(1):81-85
PURPOSE: Central lucency of pelvic phleboliths is frequently observed on plain pelvic radiographs. When it is also present on noncontrast helical CT images, pelvic phleboliths may be easily diagnosed, with no suspicion of distal ureteral calculi. The objective of this study was to determine the frequency with which this phenome-non is seen on plain radiographs and noncontrast helical CT images. MATERIALS AND METHODS: During a recent two-year period we identified 70 patients with renal colic who under-went both abdomino-pelvic radiography and noncontrast helical CT scanning. Radiographs were obtained at 70 -85 kVp and 30 -40 mA; CT scans were preformed within one month of plain radiography with parameters of 120 kVp, 200 -220 mA, 5-mm collimation, and pitch of 1 -1.6, and using soft tissue and bone window settings. With regared to the central lucency of pelvic phleboliths, as seen on both on radiographs and CT im-ages, two experienced radiologists reached a consensus. RESULTS: Among the 70 patients, a total of 150 pelvic phleboliths was found. In all cases except one, pelvic radi-ography and noncontrast helical CT revealed the same number of phleboliths. The exception was a case in which one of two phleboliths demonstrated by CT was not seen on radiographs. Pelvic radiography revealed central lucency in 95 of these 150 phleboliths (63%), but noncontrast helical CT failed to depict a hypodense center in any phlebolith. CONCLUSION: Central lucency of pelvic phleboliths, as frequently seen on plain pelvic radiographs, was not revealed by routine noncontrast helical CT in any patient.The presence or absence of central lucency on these CT images cannot, therefore, be used to differentiate phleboliths from distal ureteral calculi.
