Women attach great importance to the presence of a three-dimensional nipple upon completion of the breast reconstruction process. To meet patients' expectations, nipple-areolar complex reconstruction should achieve symmetry in position, size, shape, texture, and color, as well as minimizing donor-site morbidity. However, it is well known that regardless of the reconstructive technique, loss of nipple projection can be reasonably expected. We developed and evaluated a quick, simple, and innovative technique using injectable Integra Flowable Wound Matrix to increase nipple projection after reconstruction. Twenty breast cancer patients who underwent nipple reconstruction resulting in unsatisfactory projection were enrolled in our retrospective study. Nipple projection was measured at the time of surgery and after 6 and 12 months. A visual analogue scale was used to assess patients' satisfaction. Our technique yielded reliable results in terms of the long-lasting maintenance of nipple projection. This method is high-priced, but cost-effective, since one kit may suffice for three patients. Furthermore, our patients were very appreciative of this technique as a single-step, minimally invasive, painless procedure with no reported necessity of re-intervention.

Objectives: This case series aims to introduce the nasal floor approach for extracting inverted mesiodens. Materials and Methods: Through a retrospective chart review between January 2022 and February 2023, we included the mesiodens patients using nasal floor approach, and analysis the location of mesiodens from the anterior nasal spine (ANS), total operation time, and complications. Results: Each mesiodens was located 10 to 12 mm from the ANS and was covered with a cortical layer of the nasal floor. All mesiodens were successfully extracted without exposing the adjacent incisors or nasopalatine nerve within 30 minutes from draping to postoperative dressing. Conclusion: The nasal floor approach is an efficient extraction method that reduces bone removal and prevents anatomical damage while removing the mesiodens just below the nasal floor bone.

Although radiation and chemotherapy methods for cancer therapy have advanced significantly, surgical resection is still recommended for most cancers. Therefore, intraoperative imaging studies have emerged as a surgical tool for identifying tumor margins. Intraoperative imaging has been examined using conventional imaging devices, such as optical near-infrared probes, gamma probes, and ultrasound devices. However, each modality has its limitations, such as depth penetration and spatial resolution. To overcome these limitations, hybrid imaging modalities and tracer studies are being developed. In a previous study, a multi-modal laparoscope with silicon photo-multiplier (SiPM)-based gamma detection acquired a 1 s interval gamma image. However, improvements in the near-infrared fluorophore (NIRF) signal intensity and gamma image central defects are needed to further evaluate the usefulness of multi-modal systems. In this study, an attempt was made to change the NIRF image acquisition method and the SiPM-based gamma detector to improve the source detection ability and reduce the image acquisition time. The performance of the multi-modal system using a complementary metal oxide semiconductor and modified SiPM gamma detector was evaluated in a phantom test. In future studies, a multi-modal system will be further optimized for pilot preclinical studies.

Purpose: Currently, many operations are performed using the single-incision laparoscopic method. Although there have been recent reports on single-incision laparoscopic ileostomy, none have compared this method to conventional laparoscopic ileostomy. This study aimed to assess the safety and feasibility of single-incision laparoscopic ileostomy for anastomotic leakage following laparoscopic low anterior resections. Methods: From April 2012 to April 2017, 38 patients underwent laparoscopic ileostomy (single-incision; 19 patients referred to as group A, conventional laparoscopy; 19 patients referred to as group B) for anastomotic leakage following laparoscopic low anterior resection. We analyzed surgical and clinical outcomes between the 2 groups. Patients in whom a protective ileostomy was carried out during the initial laparoscopic low anterior resection were excluded from this study. Results: No significant differences were observed between the 2 groups in terms of patient demographics and initial operation details. Incisional surgical site infections occurred less in group A than in group B (2 of 19 vs. 9 of 19, P = 0.029). The median ileostomy operation time, amount of intraoperative bleeding, parastomal hernia ratio, hospital stay duration after ileostomy, postoperative pain score were not significantly different between the 2 groups. Conclusion: Single-incision laparoscopic ileostomy is safe and feasible method of fecal diversion for anastomotic leakage following laparoscopic low anterior resection.

어린이 영구전치의 법랑질 발육 결함이나 고정성 장치에 의한 교정치료 후 탈회 병소는 흔히 심미적 문제를 유발한다. 본 연구는 상악 전치부에 위 원인에 의한 탈회로 인하여 백반양 병소를 보이는 21명 어린이의 38개 치아를 대상으로, 최근 비침습적인 방법으로 소개된 resin infiltration 기법을 적용하고, 병소의 색조의 임상적 개선 효과를 비교, 분석하여 다음과 같은 결과를 얻었다. 1. 1주 후 색조가 개선된 병소는 발육 결함 병소의 25%, 교정 탈회 병소의 61%로 나타났다. 2. 발육 결함 병소의 40%, 교정치료 후 탈회 병소의 6%에서는 시술 전후의 색조변화를 관찰할 수 없었다. 3. 법랑질 발육결함 병소에서는 시술 직후 보다 1주 후에 더 많은 색조 변화를 관찰할 수 있었다. 결과적으로 일부 증례에서는 색조의 극적인 개선이 관찰되었으나, 또 일부 증례에서는 변화가 거의 나타나지 않았는데, 이는 병소 깊이의 차이에 기인한 것으로 사료되었다.

소아치과 임상에서는 제2유구치의 탈락 직후에 제1대구치 근심면을 직접 관찰하고 여기에 발생한 백반양 초기 우식병소를 목격할 기회가 많다. 유구치와는 달리, 잔존 기대수명이 매우 긴 제1대구치의 경우에는 근심면 초기 우식병소에 대하여 와동형성에 이은 전통적인 수복치료를 하거나 아무런 조치 없이 방관하는 것은 부적절할 것으로 사료되어, 본 연구는 이 시기 어린이들에 있어서 제1대구치 근심면 초기 우식의 유병률을 조사하고 이에 적합한 조치를 모색할 목적으로 시도되었다. 본 연구는 6개월간 부산대학교병원 소아치과에 내원한 어린이 중 제2유구치를 발거하여 제1대구치의 근심면을 직접 관찰할 수 있었던 어린이들의 124개 제1대구치를 대상으로, 근심면 백반양 초기 우식병소의 유병률을 조사하였다. 그리고 그 진행을 차단하기 위한 노력의 일환으로 평활면 초기 우식병소를 가진 치아 시편에 복합레진 접착제만 도포하거나 접착제에 이어 전색제를 도포하고 온도순환과 염색을 시행한 후, 단면을 통하여 미세누출 여부를 관찰하여 다음과 같은 결과를 얻었다. 1. 124개 관찰대상 치아 중 제1대구치 근심면이 건전한 경우는 34%에 불과하였으며, 백반양 초기 우식병소를 가진 것은 53%, 이미 우식와동이 확인된 것은 13%였다. 2. 접착제나 접착제와 전색제를 도포한 시료의 단면 관찰에서는 두군 모두에서 20% 정도의 미세 누출을 보였다. 결론적으로, 어린이 제1대구치 근심면의 초기 우식은 매우 높은 유병률을 보여 이에 대한 보다 적극적인 대처와 효율적인 비침습적 접근방법이 모색되어야 할 것으로 생각되었다.

Purpose: Reduced port surgery (RPS) for gastric cancer has been frequently reported in distal gastrectomies but rarely in total gastrectomies. This study aimed to determine the feasibility of 3-port totally laparoscopic total gastrectomy (TLTG) with overlapping esophagojejunal (EJ) anastomosis. Materials and Methods: A total of 81 patients who underwent curative TLTG for gastric cancer (36 and 45 patients with 3-port and 5-port TLTG, respectively) were evaluated. All 3-port TLTG procedures were performed with the same method as 5-port TLTG, including EJ anastomosis with the intracorporeal overlap method using a linear stapler, except for the number of ports and assistants. Short-term outcomes, including the number of lymph nodes (LNs) harvested by station and postoperative complications, were analyzed retrospectively. Results: Clinical characteristics were not significantly different among the groups, except that the 3-port TLTG group was younger and had a lower rate of pulmonary comorbidity. There were no cases of open conversion or additional port placement. All operative details and the number of harvested LNs did not differ between the groups, but the rate of suprapancreatic LN harvest was higher in the 3-port TLTG group. No significant differences were observed in the overall complication rates between the 2 groups. Conclusions: Three-port TLTG with overlapping EJ anastomoses using a linear stapler is a feasible RPS procedure for total gastrectomy to treat gastric cancer.

The aim of this case report was to describe an innovative orthodontic treatment method that combined surgical and orthodontic techniques. The novel method was used to achieve a positive result in a case of moderate crowding by employing a computer-guided piezocision procedure followed by the use of clear aligners. A 23-year-old woman had a malocclusion with moderate crowding. Her periodontal indices, oral health-related quality of life (OHRQoL), and treatment time were evaluated. The treatment included interproximal corticotomy cuts extending through the entire thickness of the cortical layer, without a full-thickness flap reflection. This was achieved with a three-dimensionally printed surgical guide using computer-aided design and computer-aided manufacturing. Orthodontic force was applied to the teeth immediately after surgery by using clear appliances for better control of tooth movement. The total treatment time was 8 months. The periodontal indices improved after crowding correction, but the oral health impact profile showed a slight deterioration of OHRQoL during the 3 days following surgery. At the 2-year retention follow-up, the stability of treatment was excellent. The reduction in surgical time and patient discomfort, increased periodontal safety and patient acceptability, and accurate control of orthodontic movement without the risk of losing anchorage may encourage the use of this combined technique in appropriate cases.
