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.

From July 1992 through January 1993, 11 patients with unstable angina received aorto-coronary bypass surgery at Dong-A University Hospital. There were 5 males and 6 females whose age ranged from 36 to 76 years old. Of the 11 patients, 3 were Functional class IL 5 were Functional class 111.3 were Functional class IV. Preoperative coronary angiography showed a significant stenosis of the left anterior descending artery in 9 cases, of its diagonal branch in I case, of the circumfiex artery in 3 cases, and of its obtuse marginal branch in 2 cases, of the right coronary artery in 4 cases, and of left main coronary artery in 3 cases. There were 4 cases of single vessel disease, 1 double vessel disease, 3 triple vessel disease and 3 left main disease. A single graft was placed in 1 patient, a double graft in 5, a triple graft in 2, and a quadriple graft in 3 patients. Left internal mammary artery plus saphenous vein graft were used in 4 patients. Postoperative complications were mediastinitis in 1, sternal instability in 2, pneumonia in 1, arrythmia in I case.

Between July, 1987, and September, 1988, 6 patients with coronary occlusive disease received coronary artery bypass surgery at Kyungpook University Hospital. There were five males and one female whose age ranged from 39 to 64 years[mean 54*8.0 years]. Of the 6 patients, 5 suffered from unstable angina, 1 suffered from stable angina. Selective coronary angiography revealed a significant stenosis of the left anterior descending artery in 6 cases, of its diagonal branch in 1 case, of the right coronary artery in 1 case, the circumflex artery in 1 case, and of its obtuse marginal branch in 1 case. The mode of anastomosis were single saphenous vein graft in 3 cases, single left internal mammary artery graft in 1 case, double saphenous vein graft with sequential anastomosis in 1 case, and left internal mammary artery plus saphenous vein graft in 1 case. Of these, 6 grafts to left anterior descending artery were done. There was no operative death, but perioperative myocardial infarction was happened in 1 case. All survivors were free of angina and discontinuing medical therapy during the follow up period[mean 7.8*5.15 months].

Use of the left internal thoracic artery(ITA) to bypass the left anterior descending(LAD) coronary artery has become the standard of care based on its superior graft patency, reduced cardiac events, and enhanced survival. But rarely we encountered with injury to the artery during harvesting which leads to loss of the merits of surgery. We reconstructed inadequate ITAa with other arterial conduits so proximal stump to be a blood source if possible. Maternal and method: Between January 1996 and March 1999, 12 patients received bypass with the reconstructed left internal thoracic artery grafts to left anterior descending artery because of an injury(n=8), short or small(n=4). Right or left ITA was used to LAD as a free graft(n=2). And the other 10 left ITAs were extended with radial artery(n=6), right ITA(n=3), saphenous vein(n=1). Composite "T" graft was made with other arterial conduits in these extended graft(n=5). Result: There was only one morbidity of minor would problem, and no mortality. The patency of extended graft to LAD was complete in 5 patients who received angiography during the period of 2wks to 2 years postoperative, but one of side branch of "T" graft occluded. All of these patients were well. Conclusion: Reconstructive extension with the use of other arterial conduit for the injured proximal ITA is warranted in any patients with acceptable results. acceptable results.

Purpose: Reconstruction of a full thickness defect of the nose is a difficult task for plastic surgeons because the anatomical characteristic, shape, and function of the nose all need to be taken into consideration. Most often, a local flap or a composite graft is used, but for a large defect, reconstruction using free flaps is the most ideal method. In free flap reconstruction, the chondrocutaneous preauricular area can be a suitable donor site. We performed a chondrocutaneous preauricular free flap with an interpositional vascular graft for reconstruction of a nasal ala. Methods: A 46 year-old male presented to the hospital with a right alar deformity induced by a dog bite. During the surgery, the existing scar tissue was removed and thereby a newly formed full thickness defect was reconstructed using the chondrocutaneous preauricular free flap with an interpositional vascular graft harvested from the descending branch of the lateral femoral circumflex vessel between the facial and superficial temporal vessels of the free flap. Results: The flap survived without flap loss and showed symmetry in its overall shape, contour, texture, and color. The patient was satisfied with the results and the surgery yielded no additional scars at the nasolabial fold area. Conclusion: The chondrocutaneous preauricular free flap is a valuable method in reconstruction of full thickness defects of the nose, and using the descending branch of the lateral femoral circumflex vessel as the interpositional vascular graft at the anastomotic site produces reliable results.

This study examined the anatomical relationships along with the variability of the facial nerve trunk and its branches with an emphasis on the intraparotid connections between the divisions. And histomorphometric observations of the facial nerve branches and fascicles were performed on 40 Korean half-heads. The facial nerve trunk was bifurcated into two main divisions(35/40, 87.5%) and the other five cases were divided into a trifurcation pattern. According to the origin of the buccal branch, the branching patterns of the facia l nerve were classified into four categories. Communications between the facial and auriculotemporal nerve branches were observed in 37 out of 40 cases(92.5%). In the histological observation, the buccal branch had the greatest number of branches(3.47), however the zygomatic branch had the largest diameters(0.93mm). This detailed description of the facial nerve anatomy wi ll provide useful information for surgical procedures such as a tumor resection. a facial nerve reconstruction, autonerve graft. and facelift.

Oral cancer ablation surgery results in tissue defects with functional loss. Accompanying neck dissection results in facial nerve weakness and dysmorphic changes. To minimize the complications after oral cancer surgery, accurate dissection without damaging facial nerve and vital structures are mandatory. Marginal mandibular branch of facial nerve should be dissected or contained in the superficial layer of deep cervical fascia to minimized facial palsy after operation. Reconstruction after cancer ablations is routine procedures and free flap reconstruction is the most commonly used. Radial forearm free flap is the most versatile flap to reconstruct soft tissue defects and it is easy to design according to the defect size and shape. However, donor site scar and secondary skin graft from thigh result in unesthetic and cumbersome wounds. Double layered collagen graft in the donor site could reduce secondary donor site for skin graft. In conclusion, oral and maxillofacial surgeon should know the exact anatomy of the face and neck during neck dissection. Radial forearm free flap is most versatile flap for soft tissue reconstruction and double collagen graft can reduce postoperative scar and there is no need for secondary skin graft.

Background: Cross-facial nerve graft is considered the treatment of choice for facial reanimation in patients with unilateral facial palsy caused by central facial nerve damage. In most cases, a traditional parotidectomy skin incision is used to locate the buccal and zygomatic branches of the facial nerve. Methods: In this study, cross-facial nerve graft with the sural nerve was planned for three patients with facial palsy through an intraoral approach. Results: An incision was made on the buccal cheek mucosa, and the dissection was performed to locate the buccal branch of the facial nerve. The parotid papillae and parotid duct were used as anatomic landmarks to locate the buccal branch. Conclusions: The intraoral approach is more advantageous than the conventional extraoral approach because of clear anatomic marker (parotid papilla), invisible postoperative scar, reduced tissue damage from dissection, and reduced operating time.

The instep flap and medialis pedis flap are both originate based on the medial plantar artery. The medialis pedis flap is based from the deep branch and the instep flap is based from the superficial branch. To increase the axial rotation, it is acceptable to ligate the lateral plantar artery. However, this can partially affect the blood supply of the plantar metatarsal arch. We restored the blood flow with a vein graft between the posterior tibial artery and the ligated stump. From 2012 to 2020, 12 cases of heel reconstruction, including seven instep flaps and five medialis pedis flaps, were performed with ligation of the lateral plantar artery. The stump of the lateral plantar artery was restored with a vein graft and between the posterior tibial artery and the ligated stump. Patients were followed for 18 months. Long-term results showed the vascular restoration of the lateral plantar artery remained patent demonstrated by doppler ultrasonography. Restoring blood flow to the lateral plantar artery maintains good blood supply to the toes. If the patient in the future develops a chronic degenerative disease, with microvascular complications, bypass surgery can still be performed because of the patency of both branches.

Anionic acrylic resin utilizing macromer(TBMA-g-MMA) copolymer was synthesized by preparing (TBMA) macromer using anionic living polymerization, followed by graft copolymerization with MMA macromer. To control the anionic site content in graft copolymer, the relative composition((TBMA) macromer/MMA ratio) of the graft copolymer was controlled at 7/3, 10/90, 15/85, 20/80, 30/70, 40/60, 50/50 in weight content. In the course of anionic living polymerization of(TBMA) macromer, broad molecular weight distribution (1.4~1.5) was obtained by using n-butyllithium-diphenyethylene initiatior system at $-78^{\circ}C$. To introduce the double bond at the end of chain in termination step, methacryloyl chloride was reacted after insertion of benzaldehyde as capping material. Moreover, TBMA parts in graft copolymer were hydrolyzed in the presence of p-toluenesulfonic acid catalyst, and neutralization of graft copolymer with triethylamine was granted acrylic resin to anionic site. Molecular weight and molecular weight distribution of(TBMA) macromer were determined by GPC, and the hydrolysis of TBMA with neutralization of acrylic resin were determined by IR and NMR. From water dispersion and stability point of view, stable dispersion state appeared at low molecular weight(TBMA) macromer with a small TBMA content as a result of scrutiny about the relation to TBMA content and branch length for(TBMA) macromer molecular weight in graft copolymer.
