Objective : Vagus nerve stimulation (VNS) has been used in epilepsy patients refractory to standard medical treatments and unsuitable candidates for resective or disconnective surgery. In this study, we investigated the efficacy of VNS to patients who had refractory result to epilepsy surgery and patients with post-traumatic epilepsy. Methods : We analyzed the effect of VNS in 11 patients who had undergone previous epilepsy surgery and patients with intractable post-traumatic epilepsy associated with brain injury. All patients underwent VNS implantation between October 2005 and December 2006. Results : We evaluated seizure frequency before and after implantation of VNS and maximum follow up period was 24 months. In the first 6 months, 11 patients showed an average of 74.3% seizure reduction. After 12 months, 10 patients showed 85.2% seizure reduction. Eighteen months after implantation, 9 patients showed 92.4% seizure reduction and 7 patients showed 97.2% seizure reduction after 24 months. Six patients were seizure-free at this time. Conclusion : We conclude that the VNS is a helpful treatment modality in patients with surgically refractory epilepsy and in patients with post-traumatic epilepsy due to severe brain injury.

Traumatic flank hernia (TFH) is rare and prone to recurrence, which makes appropriate treatment challenging. No current guidelines define the optimal timing and method of repair. Meanwhile, recent advances in laparoscopic techniques are reshaping the options for the treatment of TFH. A dual approach that utilizes both laparoscopic and open methods has not previously been reported. Herein, we present the successful treatment of TFH after blunt trauma. A 46-year-old male patient underwent elective herniorrhaphy on hospital day 3, in which laparoscopic implantation of a sublay mesh and extracorporeal implantation of an onlay mesh were performed. Such techniques may be appropriate and result in feasible outcomes in hemodynamically stable patients with large TFH who are strongly suspected of having bowel herniation or concomitant intraperitoneal injuries. Larger studies are needed to assess the long-term results.

Purpose: Epidermoid cyst may be congenital or acquired. Acquired cysts are most commonly of traumatic origin and result from an implantation or downward displacement of an epidermal fragment. Traumatic epidermoid cysts are rare tumors occurring on the nasal tip, especially resulting aesthetic procedure. So, we report a rare case of an iatrogenic epidermoid cyst in the nasal tip following rhinoplasty. Methods: A 44 - years old man had undergone rhinoplasty for several times. First time, the previous augmentation rhinoplasty and wedge osteotomy were performed nineteen months ago, lastly implant removal and unknown filler injection were performed one year ago at another local clinic. He had induration and tenderness on nasal tip and dorsum continued for 3 months. We thought that it caused by foreign body reaction with residual alloderm in nose. For removal of residual alloplastic material, open approach using transcolumellar incision was done. But, incidentally we found cystic mass on the nasal tip. Results: The findings were of an $0.8{\times}0.5{\times}0.5cm$ sized round cystic mass containing cream coloured material with a thick cheese - like consistency. The mass was completely excised and submitted for histology. This confirmed the diagnosis of an epidermoid cyst lined by keratinizing squamous epithelium. There was no induration, tenderness and sign of recurrence after excision of the mass. Conclusion: Epidermal cyst of the nasal tip region represents an unusual clinical lesion and it presents as foreign body reaction. And then, our case demonstrates that meticulous surgical approach and suture technique are the keys to prevention against iatrogenic nasal epidermoid cyst, especially in secondary rhinoplasty.

Objective : The widely accepted treatment option of a traumatic carotid cavernous fistula (TCCF) has been detachable balloon or coils based fistula occlusion. Recently, covered stent implantation has been proving an excellent results. The purpose of this study is to investigate our experiences with first line choice of covered stent implantation for TCCF at level 1 regional trauma center. Methods : From November 2004 to February 2020, 19 covered stents were used for treatment of 19 TCCF patients. Among them, 15 cases were first line treatment using covered stents. Clinical and angiographic data were retrospectively reviewed. Results : Procedures were technically successful in all 15 cases (100%). Immediate angiographic results after procedure were total occlusion in 12 patients (80%). All patients except two expired patients had image follow-up (mean 15 months). Recurred symptomatic three patients underwent additional treatments and achieved complete occlusion. Mean clinical follow-up duration was 32 months and results were modified Rankin Scale 1-2 in five, 3-4 in five, and 5 in three patients. Conclusion : The covered stent could be considered as fist line treatment option for treating TCCF patients especially in unstable vital sign. Larger samples and expanded follow-up are required to further develop their specifications and indications.

A 5-year-old intact female Maltese, a 4-year-old neutered male Chihuahua, and a 5-year-old neutered male Maltese were referred to Veterinary Medical Teaching Hospital of Seoul National University for assessment of traumatic corneal laceration accompanied by anterior lens capsule disruption by cat claw. Severe uveitis, hypopyon, fibrinous exudate, diffuse corneal edema, and/or glaucoma were observed. B-mode ocular ultrasound showed lens capsule rupture and hyperechoic lens in all three cases. Despite aggressive treatments, the three eyes continued to deteriorate with endophthalmitis, leading to enucleation. Septic implantation syndrome associated with phakitis, severe pyogranulomatous endophthalmitis, and keratitis was confirmed by histopathological examination.

A 2-year-old miniature poodle dog was referred to Seoul Animal Clinic for assessment of traumatic ocular lesion by cat claw. Corneal perforation accompanied by hyphema following iridal laceration was observed in the left eye. Topical antibiotics, mydriatics and systemic antibiotics/steroids were applied to treat severe uveitis with miosis and fibrinous exudate. Although lenticular lesion was explored after mydriasis, it was obscured by severe corneal edema around corneal perforation. Despite aggressive treatments, the uveitis became more serious in the next day. To prevent septic implantation syndrome from anterior lens capsule disruption, phacoemulsification surgery was performed. The anterior lens capsule disruption was detected during continuous curvilinear capsulorhexis. The left eye remained the vision with mild posterior capsule opacification and intermittent conjunctival hyperemia during seven-month follow-up.

의원성의 외상 혹은 감염은 신경 손상의 중요한 원인 중 하나이며, 이는 의사-환자 관계에 매우 큰 영향을 주는 일로 여겨진다. 관련 치과 술식의 예로는 임플란트 시술시 직접적인 혹은 열에 의한 손상, 근관치료시의 약제 유출, 발치시의 외력, 전달국소마취시 바늘에 의한 외상, 악골 수술로 인한 외상 등이 있다. 이러한 신경손상이 발생하지 않도록 위험군 예측 및 시술 시 주의가 필요하며, 신경 손상 시 조기 발견을 통해 제대로 대처하지 않으면 만성적 신경병증으로 발전할 수 있는 가능성이 높아질 수 있으므로 그 징후를 신속히 파악하고 적절히 관리하는 것이 매우 중요하다.

Rehabilitation of the paralyzed face as a result of trauma or surgery remains a daunting task. Complete restoration of emotionally driven symmetric facial motion is still unobtainable, but current techniques have enhanced our ability to improve this emotionally traumatic deficit. Problems of mass movement and synkinesis still plague even the best reconstructions. The reconstructive techniques used still represent a compromise between obtainable symmetry and motion at the expense of donor site deficits, but current techniques continue to refine and limit this morbidity. In chronically paralyzed face, direct nerve anastomosis, nerve graft, or microvascular-muscle graft is not always possible. In this case, regional muscle transposition is tried to reanimate the eyelid and lower face. Regional muscle includes maseeter muscle, temporalis muscle and anterior belly of the digastric muscle. Temporalis muscle is preferred because it is long, flat, pliable and wide-motion of excursion. In order to reanimate the upper and lower eyelid, Upper eyelid Gold weight implantion and lower eyelid shortening and tightening is mainly used recently, because this method is very simple, easy and reliable.

Total knee arthroplasty has become a common procedure for treatment of severe osteoarthritis, rheumatoid arthritis and post-traumatic arthritis. In the past, failure of total knee arthroplasty was commonly attributable to aseptic loosening, often associated with component malalignment, soft tissue imbalance. With improved surgical instrumentation and soft tissue balancing techiniques, failure secondary to mechanical loosening has been minimal. But surgeons are still dissatisfied with implant malalignment. Correct tibiofemoral alignment seems to be particularly important since it is generally agreed that axial deviation and imprecise implantation may lead to loosening of the implant component. Navigation systems and robotic techniques could potentially solve problems of imprecision in traditional total knee arthroplasty. It is expected that the success rate and longevity of total knee arthroplasty will be improved during the twenty first century.
