PLA/LPCL/HPCL blend fibers composed of poly (lactic acid) (PLA), low molecular weight poly ($\varepsilon$-caprolactone) (LPCL), and high molecular weight poly ($\varepsilon$-caprolactone) (HPCL) were prepared by melt blending and spinning for bioab­sorbable filament sutures. The effects of blending time and blend composition on the X-ray diffraction patterns and tensile properties of PLA/LPCL/HPCL blend fibers were characterized by WAXD and UTM. In addition, the effect of in vitro degra­dation on the weight loss and tensile properties of the blend fibers hydrolyzed during immersion in a phosphate buffer solu­tion at pH 7.4 and 37$^{\circ}C$ for 1-8 weeks was investigated. The peak intensities of PLA/LPCL/HPCL blend fibers in X-ray diffraction patterns decreased with an increase of blending time and LPCL contents in the blend fibers. The weight loss of PLA/LPCL/HPCL blend fibers increased with an increase of blending time, LPCL contents, and hydrolysis time while the tensile strength and modulus of the blend fibers decreased. The tensile strength and modulus of the blend fibers were also found to be increased with an increase of HPCL contents in the blend fibers. The optimum conditions to prepare PLA/LPCL/HPCL blend fibers for bioabsorbable sutures are LPCL contents of $5 wt\%, HPCL contents of $35 wt\%, and blending time of 30 min. The strength retention of the PLA/LPCL/HPCL blend fiber prepared under optimum conditions was about $93.5\% even at hydrolysis time of 2 weeks.

Craniofacial dysostosis is considered to be one of rarely observed syndromes characterized by premature closing of all cranial sutures. The first patient was a 4-year-old male infant who had been complaining of empyema. Clinical findings showed exophthalmos, hypertelorism and facial asymmetry. Conventional radiographs demonstrated abscence of cranial sutures and underdeveloped maxilla. CT scan demonstrated the digital impressions of the inner surface of the cranial vault, enlarged and depressed sella turcica. The second patient was a 2-year-old female infant who had been complaining of facial deformity. Clinical findings showed hypertelorism and underdeveloped maxilla. Radiographs showed premature synostosis of all cranial sutures, depressed and enlarged sella turcica, and hypoplastic maxilla. 3 years after operation, her look improved. However, resurgery may be considered to decreasing intracranial pressure and for correction of facial deformity. Two interesting cases showing ‘cloverleaf’ skulls were presented.

We report a simple technique for repairing capsular tear, using only a hook-like, cannulated instrument and braided sutures without relaying steps. A No. 2 braided suture is passed through the lumen of the instrument. Under direct arthroscopic view, the tip of the instrument is passed through the side of the capsule that has previously been separated with the probe. One end of the suture is retrieved with a grasper through a separate portal. The tip is moved back without withdrawing through the skin, and reinserted into the other side of the capsule. Holding the end retrieved earlier, the other end of the suture is retrieved with a suture retriever. After complete removal of the instrument, the suture is tied through a cannula using the standard knot tying techniques. The same procedures are repeated for other required knots.

Esophageal atresia with tracheoesophageal fistula may occur as separate, but usually occur in combination. First described by Thomas Gibson in 1696, esophageal atresia was not successfully treated until 1939 when the first two survivors of staged correction were described by Ladd and Leven. In 1941, Haight and Towsley performed the first successful one-stage primary repair. We report three cases of esophageal atresia with tracheoesophageal fistula of which were treated with one-stage surgical repair method. The operation was performed tra-nspleurally through right 4th intercostal space. The fistula in the trachea was closed with interrupted 5-O prolene sutures and esophagoesophageal anastomosis was performed with 3-O prolene single layer sutures in all cases. All patients tolerated the operative procedures and recovered uneventfully. On follow-up study, anastomotic stricture was developed in one patients, so esophageal dilatation was performed for it with the Griintzig balloon catheter and the result was satisfactory. The other patients were well-being without any complication.

Understanding the development of a skull deformity requires an understanding of the normal morphogenesis of the cranium. Craniosynostosis is the premature, pathologic ossification of one or more cranial sutures leading to skull deformities. A review of the English medical literature using textbooks and standard search engines was performed to gather information about the prenatal development and growth of the cranial vault of the neurocranium. A process of morphogenic sequencing begins during prenatal development and growth, continues postnatally, and contributes to the basis for the differential manner of growth of cranial vault bones. This improved knowledge might facilitate comprehension of the pathophysiology of craniosynostosis.

This study was performed to observe the gross reactions of surrounding maxillary sutures to the widening of midpalatal suture in the dog. Three healthy dog were chosen for the experiment. One animal was used as control, and two were used as experimental animals. Midpalatal suture was expanded total 7mm with screw for 10 days. The following results were obtained : 1. Midpalatal suture was expanded with the most width, in which anterior was be more expanded than the posterior, and shape was wedge form. 2. Interincisive suture was definitely expanded. 3. Internasal suture and interfrontal suture were slightly expanded. 4. Expansion of frontomaxillary suture, frontoparietal suture, frontonasal suture, zygomatico temporal suture, zygomatico frontal suture, zygomatico maxillary suture, occipito mastoid suture, occipito parietal suture, naso incisive suture, naso maxillary suture, and incisive maxillary suture were not observed.

A 3-year-old girl with a primitive neuroectodermal tumor (PNET) and a 6-yearold girl with acute lymphoid leukemia were referred to us because of problems with their implantable central venous ports (Port-A-Cath$^{(R)}$). On physical examination, the ports were upside-down, so a needle could notbe inserted through the membrane of the port. Right lateral side view of the chest radiogram confirmed port inversion in both cases. At operation, the ports were inverted and the transfixing sutures were totally absorbed. The ports were rotated 180 degrees and anchoring sutures placed.

The cervical esophageal stricture has various surgical modalities and difficulties in reconstruction. We had experienced a case of successful reconstruction of the cervical esophageal restenosis using the free jejunal graft, on 30 year old man had had esophageal stricture after ingestion of lye. He had undergone colon interposition[esophagocologastrostomy] with left colon feeding gastrostomy. But restenosis was occurred just above of the cervical esophagocolostomy site several times of balloon dilatation were failed. So, we decided to use of the free jejunal graft. The free jejunal graft was isolated about 15cm length with it`s vascular arcades. The graft was irrigated with the mixed solution as isotonic saline, heparin and papaverine chloride. The artery of graft was anastomosed to the branch of the external carotid artery in end to side with continuous sutures of the 8.0 Prolene. The vein of the graft was anastomosed to the branch of the anterior facial vein in end to end with continuous sutures of the 8.0 prolene. Postoperative course was uneventful and the patient was discharged after removal of the tracheostomy cannula and gastrostomy tube.

The repair of esophageal atresia with a long gap continues to pose difficulties for the surgeon. There is a general agreement that the child's own esophagus is the best, however, primary repair is not always possible. Foker JE et al. (1997) developed a technique of esophageal lengthening using external traction sutures. We successfully treated one patient with a 4.5cm gap esophageal atresia (4 vertebral spaces) using the external traction suture technique.
