  • Surgeons are increasingly using the right mini-thoracotomy approach to perform aortic valve surgery. This approach has shown better results in terms of blood loss and length of hospital stay than the sternotomy approach. For selected patients requiring aortic root and ascending aorta surgery, a right mini-thoracotomy approach may prove beneficial. In our technique, we placed a 5-cm horizontal skin incision in the right second intercostal space. Femoro-femoral cardiopulmonary bypass was established. A valved aortic conduit was used for aortic root replacement. The patient's postoperative course was uneventful, with a short hospital stay. This technique offers a minimally invasive approach to aortic root and ascending aorta surgery with easy adaptability and reduced costs.

  • Background Various surgical methods for repairing medial orbital wall fractures have been introduced. The conventional technique requires total separation of the displaced orbital bones from the orbital soft tissues. However, subperiosteal dissection around the fracture can cause additional damage. The aim of the present study is to introduce a method of reconstructing medial orbital wall fractures without subperiosteal dissection named the "push-out" technique. Methods Six patients with post-traumatic enophthalmos resulting from an old medial orbital wall fracture and 10 patients with an acute medial orbital wall fracture were included. All were treated with the push-out technique. Postoperative computed tomography (CT) was performed to assess the correct positioning of the implants. The Hertel scale and a comparison between preoperative and postoperative orbital volume were used to assess the surgical results. Results Restoration of the normal orbital cavity shape was confirmed by examining the postoperative CT scans. In the old fracture group, the median orbital volume of the fractured side was $29.22cm^3$ preoperatively, and significantly improved postoperatively to a value of $25.13cm^3$. In the acute fracture group, the median orbital volume of the fractured side was $28.73cm^3$ preoperatively, and significantly improved postoperatively to a value of $24.90cm^3$. Differences on the Hertel scale also improved, from 2.13 mm preoperatively to 0.25 mm postoperatively in the old fracture group and from 1.67 mm preoperatively to 0.33 mm postoperatively in the acute fracture group. Conclusions The push-out technique can be considered a good alternative choice for old medial orbital wall fractures with posttraumatic enophthalmos, acute medial orbital wall fractures including large fractured bone segments, and single-hinged greenstick fractures.

  • Background: The purpose of this study is to investigate the efficacy and safety of the sedation technique for implant surgery by combining the use of inhalation of nitrous oxide/oxygen with intravenous midazolam. Methods: Patients requiring surgery for the placement of dental implants were randomly allocated to two groups receiving intravenous midazolam or a combined technique using nitrous oxide/oxide and intravenous midazolam. Safety parameters, cooperation scores, anxiety scales, total amount of midazolam administered and recovery time were recorded and compared. Results: There were a statistically significant reduction in the amount of midazolam required to achieve optimal sedation (P<0.01), an overall significant reduction in recovery time (P<0.01), a significant reduction in anxiety scales (P<0.05), and a significant improvement in cooperation (P<0.05) and peripheral oxygen saturation (P<0.05) when a combined technique of inhalational $N_2O/O_2$ and midazolam was used. Conclusions: For implant surgery, this combining sedation technique could be safe and reliable, demonstrating reduction of total dose of midazolam and level of patient's anxiety and improvement in patient's recovery and cooperation.

  • Two Korean short-haired cats were admitted to the Veterinary Medical Teaching Hospital, Chonnam National University, with severe lower lip avulsion. In the first case, the treatment was performed using the tension-free suture technique with rubber tube stents. The second case was treated using the tension-free suture technique with rubber tube stents for lip avulsion and using the cerclage wiring technique for alveolar fracture. The teeth around the alveolar fracture were extracted and bone graft and collagen membrane were applied at the alveolar fracture site to stabilize the mandibular alveolar fracture. Thereafter, the cerclage wire was placed circumferentially around the mandible. In both cases, normal function of the oral cavity was successfully recovered by repairing the anatomic abnormality. In conclusion, tension-free suture technique can be a treatment option for bilateral lower lip avulsion in cats.

  • One hundred and thirty-seven patients had reconstructive surgery of injured feet with microsurgical technique in the Department of Orthopaedic Surgery at Yonsei University College of Medicine from 1983 to 1997. The results were as follows: 1. There were 89 cases in men and 48 cases in women, who together had a mean age of 21.3 years. 2. The causes of injuries were 97 cases from traffic accidents, 15 cases from burns, 11 cases from machinery injury, 5 cases from infection, 2 cases from falling, 2 cases from glass injury, 2 cases from snake bite, 2 cases from explosive injury, and 1 case from ulceration. 3. There were 47 cases with inguinal flaps, 36 cases with scapular flaps, 36 cases with parascapular flaps, 7 cases with deltoid flaps, 4 cases with lateral thigh flaps, 3 cases with latissimus dorsi flaps, 2 cases with tensor fascia lata flaps, and 2 cases with dorsalis pedis flaps. 4. One hundred and twenty-seven(92.7%) cases were successful in reconstructive surgery with microsurgical technique. 5. Functionally, the thick skin flap or sensory flap has less ulceration and good protective sensation. We considered that the function and cosmetic appearance were excellent after reconstructive surgery of the injured feet with microsurgical reconstructive technique and that the thick skin flap or sensory flap has less ulceration and good protective sensation.

  • Traumatic cleft earlobes are a common problem encountered by plastic and reconstructive surgeons. Various techniques have been reported for the repair of traumatic cleft earlobes. Usually, the techniques of split earlobe repair are divided into two categories, namely straight- and broken-line repairs. Straight-line repair is simple and easy, but scar contracture frequently results in notching of the inferior border of the lobule. It can be avoided by the broken-line repair such as Z-plasty, L-plasty, or a V-shaped flap. Between April 2016 and February 2017, six patients who presented with traumatic cleft earlobe underwent surgical correction using a combination of the inverted V-shaped excision technique and vertical mattress suture method. All the patients were female and had a unilateral complete cleft earlobe. No postoperative notching of the inferior border the lobule occurred during 6-16 months of follow-up. Without the use of a broken-line repair, both the patients and the operators attained aesthetically satisfactory results. Therefore, the combination of the inverted V-shaped excision technique and vertical mattress suture method is considered useful in the treatment of traumatic cleft earlobes.

  • Temporalis tendon transfer is a technique for dynamic facial reanimation. Since its inception, nearly 80 years ago, it has undergone a wealth of innovation to produce the modern operation. Temporalis tendon transfer is a relatively minimally invasive technique for the dynamic reanimation of the paralyzed face. This technique can produce significant and appropriate movement of the lateral oral commissure, more closely mimicking the normal side. The aim of this article is to review the technique of temporalis tendon transfer involving transferring of the coronoid process of the mandible with the insertion of the temporalis tendon via intra-oral and transcutaneous approach.

  • Video-assisted thoracic surgery (VATS) is a minimally invasive technique that has many advantages in postoperative pain and recovery time. Because of its advantages, VATS is one of the surgical techniques widely used in patients with lung cancer. Most surgeons perform VATS for lung cancer with three or more incisions. As the technique of VATS has evolved, single-port VATS for lung cancer has been attempted and its advantages have been reported. We describe our experiences of VATS for lung cancer with a single incision in this report.

  • This study was done to compare the results of the one-incision technique and the conventional two incision technique for the arthroscopic treatment of the posterior cruciate ligament injury. Fifty-five patients with the posterior cruciate ligament injury underwent the arthroscopic posterior cruciate ligament reconstruction using bone-patellar tendon-bone(BTB) graft. Patients with combined ligament injuries requiring concomitant operative treatment were excluded in this study. The conventional two-incision technique was performed in ten patients(Group I) and the one-incision technique in forty-five patients(Group II). The average duration of follow-up was 45 months in Group I(range, 40 to 50 months) and 36 months in Group II(range, 24 to 68 months). Auto BTB grafts were utilized for all patients in Group I. In Group II, 34 BTB autografts and 11 BTB allografts were utilized. The functional results were evaluated according to the Lysholm Knee Scoring scale and the Hospital for Special Surgery(HSS) knee ligament rating form. The postoperative posterior laxity was measured with a KT 1000 or 2000 arthrometer. Lysholm postoperative mean values were 90.0 in Group I and 90.6 in Group II. HSS mean values were 87.7 in Group I and 92.6 in Group II. HSS postoperative mean value showed better results in Group II(p=0.037). The average side-to-side difference of the posterior translation measured by the KT 2000 arthrometer were 2.10 mm(range, 1 to 4 mm) in Group I and 2.38 mm(range, 0 to 5 mm) in Group II. But there was no statistically significant difference. In Group II, the results of the autograft and allograft showed no significant difference. The arthroscopic posterior cruciate ligament reconstruction using one-incision technique showed good results comparable to the conventional two-incision technique. This technique minimizes potential injury to the extensor mechanism, especially vastus medialis obliquus, and scar formation over the medial femoral condyle. The operation can be finished within one tourniquet time by using only one-incision.
