Reconstruction of the auricle is one of the most fastidious fields in plastic and reconstructive facial surgery, because the ear is made up of complex cartilage framework arid its thin skin envelope. Insertion of carved rib cartilage is the most popular method for framework fabrication. But it has some disadvantages such as donor site morbidity, lesser flexibility of rib cartilage, difficulty in carving structure and distortion of cartilage after calving. Furthermore surgeon's talent and sufficient practice are necessary for a satisfactory result. So we introduced the concept of perichondral graft to improve the framework fabrication. In 1972 Skoog and associates reported that free perichondral grafts could be used to produce new cartilage. And several other reports supported the chondrogenesis of free perichondral graft. We molded the human ear using silicone rubbed impression material. And the eat mold was wrapped up in perichodrium of rabbit ear and placed in a subcutaneous pocket in formes of graft and flap. Six and eight weeks later, rabbits were sacrified and the newly formed cartilage framework was harvested. Grossly it showed the same appearance as the human eat and elastic property of normal cartilage. In histologic examination, it showed mature structure of normal cartilage; large lacunae containing spherical chondrocytes surrounded by well defined capsule.

PURPOSE: To compare the exposure rates of two wrapping materials for hydroxyapatite (HA) ocular implants (Tutoplast(R) vs. vicryl mesh). METHODS: We reviewed the medical records of 137 eyes of 137 patients who had received intraorbital HA implantation from March 1997 to March 2001. RESULTS: We used Tutoplast(R) in 72 patients and vicryl mesh in 65 patients. The mean follow-up period was 22.1 months. Implant exposure developed in four cases of eyes using vicryl mesh. No case of exposure occurred in eyes using Tutoplast(R). The mean period from operation and implant exposure was 3.5 weeks (1.5~5 weeks). CONCLUSIONS: When vicryl mesh was used as the wrapping material for HA intraorbital implant it is advisable to pay more attention to the possible postoperative implant exposure than when Tutoplast(R) was used.

We report a case of xanthoma disseminatum in a 24 year old male paitient. Multiple yellow-brown papules developed on the flexor aurfaces, such as the neck, axillae, antecubital fossae, groin, and perianal regions. Some papules were detected arouns the eyes and uvulai. biopsy specimen revealed a dense infiltrate of histiocytes, foam cells, Touton giant cells, and other inflammatory cells. No Langerhans granules were seen in the electron microscopic analysis.

Perigraft seroma is uncommon complication of polytetrafluoroethylene(PTFE) grafts applied as an arteriovenous shunt for hemodialysis. It is a collection of clear, sterile fluid confined to nonsecretory fibrous pseudomembrane, most commonly localized around the middle and distal portion of graft. The possible etiologic factors of perigraft seroma include poor graft incorporation, mechanical graft damage caused by alcohol and povidone-iodine, intraoperative streching of the graft, variations in quality control at the time of manufacture and contributing factors such as anemia and coagulopathy in uremia. The best strategy for management of perigraft seroma is not clear. spiration or drainage alone is not effective, and some authors advocate graft removal. We report a case of perigraft seroma around arterial end of PTFE graft along with a brief review of the literatures.

Myasthenia gravis is a autoimmune neuromuscular disorder characterized by weakness and fatigability of skeletal muscles. The underlying defect is a decrease in the number of available acetylcholine receptors at neuromuscular junction due to an antibody-mediated autoimmune attacks. The course of myasthenia gravis during pregnancy is not predictable. We experienced a patient of myasthenia gravis associated with pregnancy who underwent cesarean section and transient neonatal myasthenia gravis of the newborn. We present this case with brief review of the concerned literatures.

PURPOSE: This study was undertaken to correlate the CT and histopathologic findings of abscess wall. MATERIALS AND METHODS: The CT findings of 12 patients with pathologically proven brain abscess were retrospectively analyzed with particular attention to the thickness, smoothness and uniformity of enhancing abscess wall, and the results were correlated with histopathologic findings. RESULTS: Two patients with acute cerebritis showed an isodense ring on non-contrast CT(NCCT), but a true capsule formation could not be identified at pathologic examination. Six other patients with isodense ring on NCCT consisted of early to late cerebritis(3 cases), late cerebritis to early capsule(1 case), early capsule(1 case), and late capsule(1 case). These 6 cases showed ring enhancement on contrast enhanced CT(CECT) and true capsule formation pathologically. There was no isodense ring on NCCT in the remaining four patients. They consisted of early to late cerebritis(2 cases), late cerebritis(1 case), and late cerebritis to early capsule formation(1 case). These also showed ring enhancement on CECT and true capsule formation pathologically. CONCLUSION: We found that it is difficult to predict the exact stage of brain abscess on preoperative CT findings. It is suggested that clinical findings and sequential dynamic CT may provide more detailed informations for evaluation of abscess staging.

Three cases of successful pregnancy outcome after intensive care in the patients with rare mullerian anomaly of complete uterine septum, hypoplastic cervical duplication and longitudinal vaginal septum in infertility clinic are reported. These presented three cases are the reports of supporting the embryologic hypothesis of bidirectional mullerian development which fusion and resorption begins at the isthmus and proceeds simultaneously in both the cranial and caudal directions rather than the classical views of unidirectional(caudal to cranial) mullerian development. Thus, we present here three cases of rare mullerian anomaly and their pregnancy outcomes in an attempt to alert gynecologist to the possible occurrence of such a malformation. In 2 cases, successful pregnancy outcomes were achieved after abdominal or hysteroscopic uterine septotomy before pregnancy and in the last case, successful pregnancy outcome intensive obstetric care was achieved even under uncorrected uterine anomaly and complete removal of uterine septum resulted in uneventful postoperative courses at the same time of cesarean section.

Persistent cloaca is a very rare congenital malformation with the incidence of 1/50,000-250,000 births. This malformations have a single common perineal opening for the genital, urinary and gastrointestinal tracts. Because of wide spectrum of abnormal anatomy involving upper urinary tract, gastrointestinal systems, cardiovascular system, central nervous system, and respiratory system, prenatal diagnosis is difficult through ultrasound during pregnancy. It has been reported that if the anomalies are diagnosed early, they can be corrected surgically. We present a case of persistent cloaca with meconium peritonitis and hydrometrocolpos confirmed by neonatal surgery after emergency cesarean section.
