Background: The most important factor in preventing sternal complications is stable sternal approximation. We have tried to find the most effective sternal closure method by examining the incidence of sternal dehiscence with or without infection in patients with cardiac surgery through median sternotomy. Material and Method: This study was performed in 489 patients over 45 years of age with median sternotomy for open cardiac surgery. Simple closure with interrupted 6 wires was performed in 159 patients, figure-of-8 closure technique in 119, overlapping interrupted closure using 10 wires in 150, and combined closure technique of interrupted simple closure and figure-of-8 suture closure in 61. Two hundred thirty-four patients underwent valve and aortic operations and 213 patients coronary artery bypass surgery. Result: Sternal dehiscence with or without infection occurred in 12 (2.5 %) patients. The complication developed in 5 of 159 patients (3.1%) with six interrupted simple closure, in 4 of 119 patients (3.4%) with figure-of-8 closure, and in 3 of 150 patients (2.0%) with overlapping interrupted closure using 10 wires, but there was no complication in 61 patients with combined closure technique (relative risk for other closure techniques, p<0.05). There was no significant difference in the incidence of the sternal complication between valve and aortic operation group and coronary artery bypass group (3.0% vs 2.3%, not significant), but diabetes mellitus was a significant independent risk factor (odds ratio and multivariate analysis, p<0.05). Conclusion: The sternal closure technique that combines simple interrupted suture closure and figure-of-8 suture closure may be a more useful technique to enhance sternal stabilization compared to other closure techniques, such as simple interrupted closure, 8-figure closure, and overlapping interrupted closure.

Purpose: There is no consensus regarding the relationship between the width of keratinized mucosa and the health of periimplant tissues, but clinicians prefer to provide enough keratinized mucosa around dental implants for long-term implant maintenance. An apically positioned flap during second stage implant surgery is the chosen method of widening the keratinized zone in simple procedures. However, the routine suture techniques used with this method tend to apply tension over the provisional abutments and decrease pre-existing keratinized mucosa. To overcome this shortcoming, a pre-fabricated implant-retained stent was designed to apply vertical pressure on the labial flap and stabilize it in a bucco-apical direction to create a wide keratinized mucous zone. Methods: During second stage implant surgery, an apically displaced, partial thickness flap with a lingualized incision was retracted. A pre-fabricated stent was clipped over the abutments after connecting to the provisional abutment. Vertical pressure was applied to displace the labial flap. No suture was required and the stent was removed after 10 days. Results: A clinically relevant amount of keratinized mucosa was achieved around the dental implants. Buccally displaced keratinized mucosa was firmly attached to the underlying periosteum. A slight shrinkage of the keratinized zone was noted after the healing period in one patient, but no discomfort during oral hygiene was reported. Clinically healthy gingiva with enough keratinized mucosa was achieved in both patients. Conclusions: The proposed technique is a simple and time-effective technique for preserving and providing keratinized tissue around dental implants.

Background: Simple ventricular septal defect(VSD) is the most common congenital heart disease. Although closure of VSD is currently associated with a relatively low risk, experience with younger and smaller infants has been variably less satisfactory. We assessed the results of surgical closure of VSD in infant. Materials and Methods: Between 1996 and 2000, 45 non-restrictive VSD patients underwent patch repair and retrospective analysis was done. Patients were divided into two groups based on weight: group I infants weighed 5kg or less(n=16), and group II infants weighed more than 5kg(n=29). Both groups had similar variation in sex, VSD location, aortic cross clamp time and total bypass time. But combined diseases (ASD, PDA, MR) were more in group I. We closed VSD with patch and used simple continuous suture method in all patients. Results: There were no operative mortality, no reoperation for hemodynamically significant residual shunt and no surgically induced complete heart block. As a complication, pneumonia(group I: 2 cases, group II: 2 cases), transient seizure(group II: 2), wound infection(group I: 1, group II: 1), urinary tract infection(group I: 1) and chylopericardium(group I: 1) developed, and there was no significant difference between two groups(p>0.05). Conclusion: Early primary closure with simple continuous suture method was applicable in all patients with non-restrictive VSD without any serious complications.

Purpose: The zygomatic arch is a key element which composes the facial contour. In many cases of zygomatic arch fracture, it is difficult to fix rigidly the fractured segments. If reduced bone segments were not fixed rigidly, they are proven to be displaced by mastication or unintentional external forces. So, unfixed zygomatic arch fracture after reduction may require a external device of prevention of collapse. We introduce a new protector which stabilizing the fractured segments to prevent for collapse of the reduced zygomatic arch fracture. Methods: After reduction of zygomatic arch with blind approach(Gillies', Dingman or Keen's approach), bone segments was pulled with percutaneous traction suture in medial aspect of zygomatic arch. Then, the suture was fixed with Aqua $splint^{(R)}$, externally. And intraoperative and postoperative X-ray was done. The splint was removed on 14 days after the operation. Results: 5 patients were treated with this method. 4 patients of total patients had no collapse in zygomatic arch. There was minimal collapse in one patient. Postoperative complications such as facial nerve injury, mouth opening difficulty, contour deformity, infection, scar were not observed. Conclusion: In comparison with other techniques, this technique has several advantages which are simple and easy method, short operation time, no scar, less soft tissue injury, and facilitated removal of splint. Therefore, Aqua $splint^{(R)}$ would be a good alternative to prevent for collapse in unstable zygomatic arch fractures

Twenty one cows in Goyang and Paju cities were referred due to displacement of the abomasum and foreign body in the rumen. Omentopexy and rumenotomy through a right flank celiotomy were performed for treatment of abomasal displacement and the foreign body removal in the rumen. The right paralumbar fossa is clipped and prepared surgically. Local anesthesia is instituted by performing inverted L block. The abdomen was entered through 25 to 30 cm vertical incision in the right paralumbar fossa starting 4 to 5 cm ventral to the transverse processes of the lumbar vertebrae. A 14-gauge needle with rubber tubing attached is inserted to relieve the gaseous pressure and to facilitate further exploration and manipulation. The rumen was gently pulled out of the abdominal cavity and incision was made at the omentum. Rumenotomy was done and retrieved the foreign body. After the rumen was rinsed with sterile saline, the rumen wall was closed by a Lembert suture technique. The omentum was closed by a simple continuous suture. Right flank omentopexy was performed for the surgical correction of abomasal displacement. Recovery results among 21 cows included 9 excellent, 5 good, 2 fair and 5 bad. It was considered that operation of abomasal displacement and foreign body removal in the rumen through right flank celiotomy was a good surgical technique to reduce expenses, surgical pain, and surgery time.

Purpose: Male nipple hypertrophy is a rare condition but is a social embarrassment for individual. The currently available techniques of nipple reduction already described in the literature for female patients are discussed, but the goal of treatment is different in male patients. In male patient, the diameter as well as vertical height should be reduced simultaneously to achieve better aesthetic results. Our new technique can reduce the diameter of the hypertrophic nipple as well as the vertical height efficiently and simply. Methods: A 19-years-old man with nipple hypertrophy on the right chest presented. The flap is designed based on the site of left nipple, symmetry, the diameter, and the projection desired. The widths of the V flaps determine projection, whereas the diameter of the C flap determines the diameter of the nipple and top of the new nipple. Unnecessary hypertrophic tissues are extirpated and the V flaps are elevated. The nipple base is reduced by purse-string suture technique. The V flaps are wrapped around, and C flap is used as a cap. Results: No complication including nipple necrosis or sensory loss were found during follow-up period. The normal symmetry of the nipple contour was restored. Conclusion: We describe a simple technique for male nipple reduction using a C-V flap with purse-string suture. In our experience, this technique has provided good aesthetic result and patient satisfaction.

The authors introduce an operative technique which is simple and effective for the treatment of the large prepatellar bursitis, avoiding problems by the conventional open technique such as tender scar, infection and recurrence. We treated three cases of the large refractory prepatellar bursitis caused by acute direct trauma. Bursectomies were performed by using an arthroscope and percutaneous multiple sutures were applied to the overlying skin with mattress fashion. There were no complications after treatment over one year follow-up. We suggest that this technique is very useful, greatly minimizes the chance of recurrence and reduces the possibility of post-operative infection.

Purpose: The aim of this study was to clinically assess the impact of a prefabricated implant-retained stent clipped over healing abutments on the preservation of keratinized mucosa around implants after implant surgery, and to compare it with horizontal external mattress sutures. Methods: A total of 50 patients were enrolled in this study. In the test group, a prefabricated implant-retained stent was clipped on the healing abutment after implant surgery to replace the keratinized tissue bucco-apically. In the control group, horizontal external mattress sutures were applied instead of using a stent. After the surgical procedure, the width of the buccal keratinized mucosa was measured at the mesial, middle, and distal aspects of the healing abutment. The change in the width of the buccal keratinized mucosa was assessed at 1 and 3 months. Results: Healing was uneventful in both groups. The difference of width between baseline and 1 month was $-0.26{\pm}0.85mm$ in the test group, without any statistical significance (P=0.137). Meanwhile, the corresponding difference in the control group was $-0.74{\pm}0.73mm$ and it showed statistical significance (P<0.001). The difference of width between baseline and 3 months was $-0.57{\pm}0.97mm$ in the test group and $-0.86{\pm}0.71mm$ in the control group. These reductions were statistically significant (P<0.05); however, there was no difference between the 2 groups. Conclusions: Using a prefabricated implant-retained stent was shown to be effective in the preservation of the keratinized mucosa around implants and it was simple and straightforward in comparison to the horizontal external mattress suture technique.

Background Buried non-incisional double-eyelid blepharoplasty is a popular aesthetic procedure. Although various modified continuous suture techniques have been used to create a more natural appearance and to reduce downtime, complications such as loosening of the double fold, asymmetry, and foreign body reactions have been observed. Methods This study included 250 patients who underwent double-eyelid blepharoplasty between March 1997 and November 2012 using a modified single-knot continuous buried non-incisional technique. With 4 stab incisions in the upper eyelids, one of two needles loaded with double-armed 7-0 nylon was passed in one direction alternately through the dermis and the conjunctiva, while the other needle was passed subconjunctivally in the opposite direction. Both ends of the sutures were knotted within a lateral stab incision of the upper eyelids and were buried in the orbicularis oculi muscle. Results Most patients displayed satisfactory aesthetic results, and no significant complications occurred. There was no obvious regression of the double fold; however, 3 patients required reoperation to correct loosening of the fold on one side during the follow-up period. One patient presented with the suture knot subcutaneously, and the knot was removed in the clinic. Conclusions The modified single-knot continuous buried non-incisional technique is a simple and less time-consuming method for a durable double fold and provides satisfactory aesthetic results.
