  • Deviated nose is highly challenging in rhinoplasty since the surgeon should consider both aesthetic and functional aspects of the nose. Deviated nose correction is surgically complex, and a thorough understanding of the mechanical and physiological changes of intranasal structures, including the septum and turbinates, is necessary for functional improvement.

  • Septo-optic dysplasia is a congenital anomaly with diverse phenotypes from normal to mixtures of visual abnormality, endocrine dysfunction, psychomotor retardations and epileptic seizures. It is characterized by optic atrophy, pituitary dysfunction and midline structure abnormalities in corpus callosum or septum pellucidum. Diagnosis of septo-optic dysplasia plus is made when cortical malformations accompanied. Here we report a middle-aged woman with septo-optic dysplasia plus having unilateral optic atrophy, agenesis of septum pellucidum and cortical malformations.

  • We treated a 37-year-old male with traumatic hematoma in the suprapatellar bursa that had developed in the form of persistent swelling on suprapatellar area of left knee after blunt trauma. Though there were no obvious abnormal findings on plain roentgenographs, an isolated suprapatellar cystic lesion with fluid-fluid level on T2-weighted sagittal image of MRI was noted. We found the suprapatellar plica with complete septum and no synovitis in the knee joint proper by arthroscopy. We incised the plica and found leakage of blood-stained fluid from the suprapatellar bursa. There were no findings of pigmented villonodular synovitis or other tumorous lesions. At 6 months after surgery, the patient felt symptom-free and there was no recurrence.

  • We developed an optimal design interface based on VBA(Visual Basic Application) that takes advantage of API(Application Program Interface) function of commonly used EM analysis software. The developed interface is adopted for an optimal design of a septum in a waveguide tee junction using PSO(Particle Swarm Optimization) algorithm. The objective function of the optimal design is defined by $S_{11}$-parameter of the waveguide tee junction Design variables are established as position of the septum, that are changed to satisfy the design goal Using the developed design interface and PSO algorithm, the objective function converged to the smallest value, showing the validity of the proposed method. The design interface was developed using Microsoft Excel software, enabling easy control of design parameters for user. Also, various analysis parameters can be set in the Excel interface, including waveguide input mode and frequency. After completion of the design, field solutions at user-specified positrons can be extracted to the output files in complex number form.

  • Objectives : This study was conducted to find out the effect of Yukmijiwhangtanggamibang (YM) on growth, learning and memory of rats. Methods : It was divided SD rats into Sham group, 192 Saporin injection(SA+Saline) group and Injection of 192 Saporin with YM(SA+YM) group. Growth measure length of bone and tail. Memory performance was used aquisition test and learning retention of morris water maze. It was detected acetylcholinesterase(AChE), cholineacetyltransferase(ChAT) at medial septum and hippocampus by immunohistochemistry Results : Body Weight of the SA+YM Group increased effectively, as compared with SA Saline group. Growth of bone in the SA+YM Group increased effectively, as compared with SA+Saline group. Growth of Tail in the SA+YM Group increased effectively, as compared with SA_Saline group. The SA+YM Group in Aquisition Test improved effectively, as compared with SA+Saline group. The SA+YM Group in Learning Test improved effectively, as compared with SA+Saline group. The numbers of ChAT cells in Medial septum increased effectively, as compared with SA+Saline group. The numbers of ChAT cells in CA1 of Hippocampus increased, but was not effective. Conclusion : These results suggest that YM has an improving effect on the impaired learning through the effects on memory registration and retrieval.

  • The primary procedural components of deviated nose correction are as follows: osteotomy to correct bony deviation, septal deviation correction, manipulation of the dorsal septum to correct upper lateral cartilage deviation, and correction of functional problems (manipulation for correction of internal valve collapse and hypertrophy of the inferior turbinate). The correction of tip and nostril asymmetry cannot be overemphasized, because if tip and nostril asymmetry is not corrected, patients are unlikely to provide favorable evaluations from an aesthetic standpoint. Tip asymmetry, deviated columella, and resulting nostril asymmetry are primarily caused by lower lateral cartilage problems, which include deviation of the medial crura, discrepancy in the height of the medial crura, and asymmetry or deformity of the lateral crura. However, caudal and dorsal septal deviation, which is a more important etiology, should also be corrected. A columellar strut graft, correction of any discrepancy in the height of the medial crura, or lateral crural correction is needed to correct lower lateral cartilage deformation depending on the type. In order to correct caudal septal deviation, caudal septal shortening, repositioning, or the cut-and-suture technique are used. Surgery to correct dorsal septal deviation is performed by combining a scoring and splinting graft, a spreader graft, and/or the clocking suture technique. Moreover, when correcting a deviated nose, correction of asymmetry of the alar rim and alar base should not be overlooked to achieve tip and nostril symmetry.
