목적 : 관절경 검사에서 전방 십자 인대의 만성 파열에서 파열된 전방 십자 인대가 슬관절 내에서 반흔을 형성하고 있는 경우 전방 전위 감소 여부, 자기 공명 영상 및 동반손상을 분석하고자 한다. 대상 및 방법 : 1996년 12월부터 2000년 5월까지 전방 십자 인대의 만성 파열이 있었던 19예를 대상으로, 관절 계측기의 환측과 건측의 도수 전방 최대 전위차, 자기 공명 영상 및 동반손상을 분석하였다. 결과 : 만성 파열이 있었던 19예 중 7예$(37\%)$의 KT-2000관절계측기 검사 중 환측과 건측의 도수 최대 전방 전위차는 평균 $2.78{\pm}2.41mm$$(0\~6.5)$로, 반흔 형성이 없었던 12예의 평균 $5.75{\pm}2.52mm(3\~10)$와 비교하여 유의한 차이를 보였으며, 반월상 연골의 손상은 반흔을 형성하고 있던 7예 중 2예$(28\%)$, 반흔 형성이 없었던 12예 중 8예$(67\%)$에서 동반되었다. 자기 공명 영상 소견은 파열된 전방 십자 인대의 원위 조각이 비교적 직선주행으로 대퇴 기시부를 향하는 경우가5예, 연속성을 유지하며 국소적인 각형성이 있는 경우가 2예였다. 결론 : 전방 십자 인대 만성 손상의 관절계측기 검사에서 유의한 전방 전위가 없고, 자기 공명 영상에서 파열된 원위 조각이 비교적 직선 주행으로 대퇴 기시부를 향하거나 연속성을 유지하며 국소적인 각 형성을 이루는 소견들을 보이는 예에서는 파열된 전방 십자 인대의 반흔 형성을 고려해야될 것으로 사료되며, 반흔을 형성하고 있는 예에서 반월상 연골의 손상 빈도가 낮은 소견은 전방 십자 인대 완전 파열의 자연경과 연구에 도움이 되리라 생각한다.

Urinary tract infection (UTI), the most common bacterial disease in childhood, is frequently associated with urinary tract anomalies (15-50%) and can induce renal scarring, which is a cause of hypertension and chronic kidney disease. Despite the high risk of renal scarring in infancy, the diagnosis may be delayed due to its nonspecific presenting symptoms; moreover, over-diagnosis is frequent due to the contamination of urine samples. The delay in diagnosis and treatment may induce sepsis or renal scar, while over-diagnosis is responsible for unnecessary antibiotic treatment and costly urinary imaging studies. UTI guidelines have been ever-changing for the past three decades, but some controversial issues remain. This article is a revision of the previous KSPN (Korean Society of Pediatric Nephrology) guideline and addresses the recent controversies concerning childhood UTI.

Corner mouth lift is in increasing demand among young patients in East Asia. Although various surgical methods exist for corner mouth lift, many patients are reluctant to undergo surgery due to fears of postsurgical scarring. We present a new technique aimed at reducing postoperative scarring. The technique involves triangular excision of the corner of the mouth and incision of the commissure with transposition of a lateral vermilion flap to lift the corner of the mouth. The muscle around the corner of the mouth is dissected to release tension. The corner mouth lift was successfully performed in all patients. It can be effectively used even in patients, such as young Asian women, who are susceptible to hypertrophic scars.

Many clinicians expect complete healing after the removal of temporary anchorage devices, but clinical examination may reveal scar-like tissue. This report presents the typical features of scarring detected after the removal of miniscrews, and the clinical outcome of scar revision along with its pathologic features.

Squamous cell carcinoma (SCC) is a form of neoplasm that origins from the epithelial surface of many organs. Ocular occurrence in small animals is rare, especially in the central cornea without the involvement of limbus or conjunctiva. In the current case, a 10-year-old, spayed female Shih-Tzu was presented with a central corneal mass. Through an ophthalmic examination the sign of corneal scarring around the mass was found. Pink fleshy lesion that protruded outward was removed through superficial keratectomy. The mass with the size of $8.5{\times}6.5$ millimeter was histopathologically diagnosed as corneal SCC infiltrating not only the epithelium, but also the superficial corneal stroma with surrounding superficial lymphoplasmacytic and neutrophilic chronic keratitis. Also, the adjacent, non-affected corneal epithelium was markedly hyperplastic and keratinized; the adjacent stroma was moderately vascularized and fibrotic. The pulse-dose therapy using 1% topical 5-flourouracil were applied for five cycles. The tumor has not recurred through nine months of follow-up time.

Purpose: Single hair transplantation for eyebrow loss has been considered as a good method of achieving natural appearance of eyebrow. To date, however, no study has reported the survival rate following single hair transplantation for cicatricial eyebrow alopecia. Methods: We performed single hair transplantation using Choi hair transplanter for 49 cases of scarring eyebrow loss from March 2003 to March 2006. Of these cases, 33 could be under a follow-up postoperatively for more than seven months. These 33 cases comprised 20 men and 13 women. Mean follow-up period was 12 months (7-36 months). In 17 patients(51.5%), 100 to 200 hairs were unilaterally transplanted. Results: Following initial hair transplantation, the surgical outcome was excellent in 11 cases(33.3%), good in 12 cases(36.4%), fair or poor in the remaining ten cases(30.3%). All procedures were done under intravenous sedation and local or regional block anesthesia. It took about one and a half hours for us to transplant 200 hairs. The shape of eyebrow was aesthetically acceptable with a good direction and an ideal inclination of hairs. No patients developed notable complications, while 30 percent had a low survival rate. Conclusion: Single hair transplantation using Choi hair transplanter is a safe, effective surgical method for scarring eyebrow loss.

Vocal fold scarring is an intractable phonosurgical condition. The number of patients with vocal fold scars is increasing with the aging of society and with the increasing application of laryngeal microsurgery. Many methods are available to treat these, including voice therapy, stem cells, regenerative scaffolds, and growth factors. However, no standard treatment strategy has yet been established, and novel techniques are required. Basic fibroblast growth factor has been shown to be effective for the treatment of mild chronic vocal fold scarring. The combined use of basic fibroblast growth factor and regenerative scaffolds is currently under investigation. Here, we report a female patient in whom vocal fold scarring developed after two laryngeal microsurgeries. We performed laryngeal microsurgery to remove the scar tissue and used basic fibroblast growth factor and a collagen scaffold to promote healing. The patient's voice quality was greatly increased, and she was content with her voice after 2 years of follow-up. This is the first report of this methodology in Korea and is presented along with a review of the literature.

Background: Minimizing scarring has long been a challenge in plastic surgery. Factors affecting scar formation are well known, but the effect of some patient-specific factors such as dermal thickness remains unverified. Management of factors predictive of scarring can improve postoperative patient satisfaction and scar treatment. Methods: For 3 years, we used ultrasonography to measure dermal thickness in female patients who had undergone thyroidectomy for cancer at our hospital. We confirmed the influence of dermal thickness on hypertrophic scar formation and the Patient and Observer Scar Assessment Scale scar score 6 months after surgery. Results: There was a positive correlation between dermal thickness and scar score (p<0.05), and dermal thickness appears to be a cause of hypertrophic scar formation (p<0.05). Conclusion: Thick dermis was found to cause poor scar formation and hypertrophic scarring. Prediction of factors that can influence scar formation can be used to educate patients before surgery and can help in scar management and improvement in patient satisfaction.
