Most of aortic injuries after blunt chest trauma usually occur at the aortic isthmus and are identified in the emergency department soon after arrival. Delayed aortic injures by fractured posterior ribs, however, are relatively rare and have been reported only a few times. We recently experienced an iatrogenic descending aortic injury sustained as a result of a direct puncture by a sharp rib end after surgical stabilization of rib fractures.

Purpose: This study tested the effectiveness of brochure- and video-based education on managing surgical site infections by operating room health personnel. Methods: From April 20 to May 4, 2021, 34 operating room health personnel were subjected to training on surgical site infection management using brochures and educational videos. A survey was then conducted on knowledge, perception, and adherence regarding surgical site infection management. Results: After receiving training on surgical site infection management, the knowledge score increased significantly (15.15±2.09 vs.19.70±1.96, p<.001). However, the perception and adherence scores were already near perfect before the intervention and did not further increase after the intervention. Conclusion: It is necessary to develop and utilize continuous and substantive educational programs to improve perception and adherence of surgical site infection management.

Various treatments for trigeminal neuralgia (TN) are known to yield initial satisfactory results; however, the surgical treatment has excellent long-term outcomes and a low recurrence rate. Surgical treatment addresses the challenge of vascular compression, which accounts for 85% of the causes of TN. As for surgical treatment for TN, microvascular decompression (MVD) has become the surgical treatment of choice after Peter J. Jannetta reported the results of MVD surgery in 1996. Since then, many studies have reported a success rate of over 90% for the initial surgical treatment. Most MVDs aim to separate (decompress) the culprit vessel from the trigeminal nerve. To increase the success rate of surgery, accurate indications for MVD and management of the offender vessels without complications are critical. In addition, if there is no vascular compression, partial sensory rhizotomy or internal neurolysis can be performed to improve surgical outcomes.

Germectomy is a surgical method most typically performed in young adults. The indications for treatment are controversial. The purpose of this review was to determine the correct indications for germectomy and to discuss the advantages and disadvantages of the procedure. We reviewed the surgical techniques (anesthetic methods, patient preparation, and flap designs) and complications. Germectomy for orthodontic purposes is a common indication for surgical removal of tooth germ among young patients. Several studies have supported removal at an earlier age to produce fewer surgical complications. Several surgical techniques have been described in the literature.

Objective : Ossification of posterior longitudinal ligament (OPLL) in the thoracic spine may cause chronic compressive myelopathy that is usually progressive, and unfavorable by conservative treatment. Although surgical intervention is often needed, the standard surgical method has not been established. Recently, it has been reported that posterior decompression with dekyphosis is effective surgical technique for favorable clinical outcome. The purpose of this study was to evaluate the surgical outcomes in patients with thoracic OPLL according to dekyphosis procedure and to identify predictive factors for the surgical results. Methods : A total of 25 patients with thoracic OPLL who underwent surgery for myelopathy from May 2004 to March 2017, were retrospectively reviewed. Patients with cervical myelopathy were excluded. We assessed the clinical outcomes according to various surgical approaches. The modified Japanese orthopedic association (JOA) scores for the thoracic spine (total, 11 points) and JOA recovery rates were used for investigating surgical outcomes. Results : Of the 25 patients, 10 patients were male and the others were female. The mean JOA score was 6.7±2.3 points preoperatively and 8.8±1.8 points postoperatively, yielding a mean recovery rate of 53.8±31.0%. The mean patients' age at surgery was 52.4 years and mean follow-up period was 40.2 months. According to surgical approaches, seven patients underwent anterior approaches, 13 patients underwent posterior approaches, five patients underwent combined approaches. There was no significant difference of the surgical outcomes related with different surgical approaches. Age (≥55 years) and high signal intensity on preoperative magnetic resonance (MR) image in the thoracic spine were significant predictors of the lower recovery rate after surgery (p<0.05). Posterior decompression with dekyphosis procedure was related to the excellent surgical outcomes (p=0.047). Dekyphosis did not affect the complication rates. Conclusion : In this study, our result elucidated that old age (≥55 years) and presence of intramedullary high signal intensity on preoperative MR images were risk factors related to poor surgical outcomes. In the meanwhile, posterior decompression with dekyphosis affected favorable clinical outcome. Posterior approach with dekyphosis procedure can be a recommendable surgical option for favorable results.

The objective of the present study was to evaluate the effectiveness of autoligation techniques for castrating healthy male small breed dogs. Forty dogs were divided into four groups, with 10 in each group, based on maturity and the surgical technique used: 1) immature dogs aged less than 1 year, with autoligation of the spermatic cord via a scrotal approach (SAL) as the surgical technique (SAL-IM); 2) mature dogs aged 1 year or older, with the same SAL surgical technique (SAL-M); 3) immature dogs aged less than 1 year, with double ligation of the spermatic cord with an absorbable suture via a prescrotal approach (PDL) as the surgical technique (PDL-IM); and 4) mature dogs aged 1 year or older, with the same PDL surgical technique (PDL-M). The effectiveness of the surgical technique was evaluated by comparing the operating time and complications between these four groups. The significant decreases in operating times were found in SAL-IM and SAL-M compared with those of PDL-IM and PDL-M (p < 0.01 and p < 0.01). Regardless of maturity, the SAL surgical technique reduced operating time by approximately 69.5% compared with the PDL surgical technique. When the complication severities were scored, the results showed no significant differences among the four group. The autoligation technique for castration in healthy male small breed dogs is considered to be effective because the operating time consuming is less than conventional techniques.

Background During the early stages of lymphedema, active physiologic surgical treatment can be applied. However, lymphedema patients often have limited knowledge and misconceptions regarding lymphedema and surgical treatment. We analyzed the correlations between lymphedema severity and surgical technique according to patients' awareness of surgical treatment for secondary upper extremity lymphedema (UEL). Methods Patients with UEL diagnosed between December 2017 and December 2019 were retrospectively evaluated. At the time of their presentation to our hospital for the treatment of lymphedema, they were administered a questionnaire about lymphedema and lymphedema surgery. Based on the results, patients were classified as being aware or unaware of surgical treatment. Lymphedema severity was classified according to the arm dermal backflow (ADB) stage and the MD Anderson Cancer Center (MDACC) stage based on indocyanine green lymphography conducted at presentation. Surgical techniques were compared between the two groups. Results Patients who were aware of surgical treatment had significantly lower initial ADB and MDACC stages (P<0.05) and more frequently underwent physiologic procedures than excisional procedures (P=0.003). Conclusions If patients are actively educated regarding surgical treatment of lymphedema, physiologic procedures may be performed during the early stages of UEL.

Ingrown toenails are most common among school-age children and adolescents though they can be observed at any age. Causes of ingrown toenails are increased curvature, trauma, and external pressure. Treatment of ingrown toenails can be broadly characterized as conservative and surgical. Conservative treatment can be performed using various methods, such as a gutter splint, dental floss, and cotton. Surgical treatments may be divided into two main approaches; narrowing of the nail plate and debulking of periungual tissues. However, these various conservative and surgical treatments have high recurrence rates, and thus, the author used a permanent surgical method based on the use of a paronychium flap to treat a 15-year-old male adolescent with excessive periungual tissues and curved ingrown toenails who did not improve despite conservative and several surgical treatments over 4 years. Subsequently, toenail shape was maintained without recurrence 22 months after surgery, and there were no complaints of inflammation or pain while walking. This simple surgical method can be performed on patients with advanced ingrown toenails due to excessive periungual tissues and nail curvature and can be expected to have permanent effects.
