Purpose: This systematic review aimed to compare the efficacy, defined in terms of the mean percentage of root coverage (mRC), of surgical treatment approaches combined with adhesive restorations of non-carious cervical lesions (NCCLs) to that of root coverage alone in patients with a single gingival recession (GR) and NCCL. Methods: A literature search was conducted to identify longitudinal studies reporting the mRC following treatment for the correction of GR defects associated with NCCLs using a combination of surgical and restorative techniques in systemically and periodontally healthy patients. Results: The search resulted in the retrieval of 12,409 records. Seven publications met the inclusion criteria for the qualitative synthesis of data. The mRCs ranged from 69% to 97%. In the medium term, the gingival margin position was more stable when a connective tissue graft (CTG) was used, independently of whether restoration of teeth with NCCLs was performed. Conclusions: The strength of the evidence was limited by methodological heterogeneity in terms of study design as well as the unit and period of analysis, which precluded a metaanalysis. Although no definitive conclusion could be drawn due to the lack of sufficient evidence to estimate the effectiveness of the interventions, CTG-based procedures contributed to gingival margin stability regardless of the performance of restoration to treat NCCLs.

Delayed esophageal rupture due to blunt injury is not new. However, rupture due to suspected barotrauma is very rare. We describe a case of esophageal rupture in a male 24-year-old patient after diving in shallow waters. The patient was quadriplegic and could not experience the typical chest pain related to rupture and resulting mediastinitis. The rupture was discovered 4 days after emergency decompressive laminectomy and fusion for his cervical spine. The rupture was evidently caused by barotrauma and was discovered four days after admission. He underwent primary closure and pericardial flap as a life-saving procedure.

오늘 날, 물질 문명이 고도로 발달함에 따라 인두 및 인두 손상이 날로 증가하는 경향을 보이고 있다. 교통 사고나 운동 경기는 폐쇄적 외상을 일으키기 쉽고 빈도는 적지만 심각한 증상을 초래하는 개방적 외상의 원인으로는 총상이나 자상 등을 들 수 있다. 인후두의 개방적 외상에서 가장 문제가 되는 것은 적절한 치료에 있다. 이 부위의 외상은 손상의 정도나 범위에 따라 차이는 있지만 신속한 처치가 요구되고 협착이나 누출 등과 같은 심각한 후유증을 남기기 때문에 적절한 치료 방법이 요구되는 것이다. 일반적으로 이에 대한 치료는 적절한 기도 유지를 위한 기관절개술과 단순 봉합등을 일차적으로 시행하고 차후에 후유증에 대한 이차 수술을 시행하는 것이 보통이다. 최근, 저자들은 자상으로 인해 인두 뿐만 아니라 인두까지 광범위한 개방적 외상을 입고 이차 감염까지 일으켜 인후두 조직 및 전경부 피부의 심한 결손을 보인 환자에게 잔여 후두 적출술을 시행한 후 피부봉이나 육경피부변을 사용하지 않고 전경부 피부변을 이용해서 피부 결손부를 얻었기에 문헌적 고찰과 함께 보고하는 바이다.

Ten intrabony defects in 10 patients were treated by flap surgery including root surface debridement and placement of an expanded polytetrafluoroethylene(ePTFE) membrane. The membranes were removed after 4-6 weeks. This study was performed to examine the retrived ePTFE membrane by scanning electron microscopy(SEM) for bacterial contamination and adherent connective tissue elements, and to compare it with clinical conditions. The cervical portion of the membrane, which in most cases had become partially exposed to the oral cavity, had a bacterial deposit. Small bacterial colonies and a scatter of single cells in some instances extended into the apical portion of the membrane. Fibroblast-like cells, erythrocytes and fibrous structures were seen in the apical portion of the membrane. Outer surface of membrane tends to more bacterial contamination than inner surface(p<0.01), and upper portions more than lower portions(P<0.01). Comparison of ultrastructural findings and clinical conditions revealed that extent of bacterial contamination of the membrane correlated with gingival inflammation and extent of membrane exposure, but it was not significant statistically. The results suggested that gingival inflammation and membrane exposure affect periodontal regeneration by the use of ePTFE membrane.

Submandibular gland ptosis is a common impediment to obtaining superior surgical aesthetic results in neck lift surgery. Techniques for suspending the submandibular gland have been proposed, but these procedures have the drawbacks of disturbing the floor of the mouth mucosa and periosteum. We present an approach of submandibular gland suspension for the treatment of gland ptosis by employing a platysma and hyoid bone fascia cradle. Our technique was performed on cadaveric models. The platysma muscle and hyoid bone cradle for submandibular gland ptosis was created on the left side of the neck in two cadavers. A submental incision with sharp dissection was performed to raise a supraplatysmal flap. A subplatysmal plane was developed until the submandibular gland was identified. Sutures were used to pexy the platysma to the hyoid bone periosteum and deep cervical fascia, tightening the overlying muscle and in turn elevating the submandibular gland. Submandibular gland ptosis must be corrected in order to achieve exemplary aesthetic results. Our approach of creating a cradle with the platysma and hyoid bone avoids the potential complications of previously described sling procedures, while still maintaining the integrity of the gland and surrounding tissues.

Mesenchymal chondrosarcoma is a rare malignant tumor of bone and soft tissue. This aggressive form of chondrosarcoma represents only 3% to 9% of all chondrosarcomas. This neoplasm is characterized by sheets or clusters of undifferentiated spindle or round cells surrounding discrete nodules of well-differentiated cartilage. We experienced a case of mesenchymal chondrosarcoma on mandibular body. Two years ago, the patient had been treated the intrabony cystic lesion on mandiblular left body. At that time, cartilage portion was not detected in the cystic specimen. Two years after cyst enucleation, the recurred large neoplasm in the mandibular left body was noted, and it was diagnosed as 4.5 cm sized mesenchymal chondrosarcoma. The mandibular tumor was widely resected and rigid-plate and cervical musculocutaneous flap were used for reconstruction of resected bone and soft tissues. No complications and recurrence were noted for 6 months postoperatively.

저자들은 1예의 전두부 연조직 결손과 2예의 경부와 안면에 형성된 다발성의 반혼구축 환자에서 조직확장술올 이용하여 양호한 두경부의 연조직 재건을 얻을 수 있었다. 다양한 연조직의 결손이나 변형에서 적절한 증례를 선택하여 올바르게 적용할 경우 조직 확장술은 유용한 재건방법이 될 수 있을 것으로 생각된다.

Purpose: Angiosarcoma is a tumor of mesenchymal origin with an extremely high rate of metastasis and invasiveness. This tumor is notorious for its very poor prognosis, although surgical excision followed by radiation therapy is considered to be effective by many. The authors experienced three angiosarcoma patients with their tumors removed and wounds covered with split-thickness skin grafts and/or latissimus dorsi free flaps. Methods: Three patients were admitted to our hospital showed plaques of different morphology. Based on their medical records, these patients were classified by sex, age, type of reconstruction, recurrence, and further treatment after surgical removal. Results: All patients were male, with a mean age of 72 years (range, 66 to 77 years). Split-thickness skin grafts with latissimus dorsi free flaps were performed on two cases, and of these two cases, cervical lymph node biopsy was done in one case, and radical neck dissection was done in the other. In all cases, radiation therapy was done within two weeks of tumor removal. Distant metastasis occurred without local recurrence in two of the cases. Lung was the first organ affected by metastasis. In the remaining case, the tumor recurred locally 6 times, and additional excision was necessary. All patients died due to local recurrence and lung metastasis. Conclusion: Irregular margins and high recurrence and metastasis rates cause a poor prognosis in large angiosarcoma of the scalp. Radiotherapy and chemotherapy should be strongly considered in large angiosarcomas.

치은연 하방에 치아 우식증이나 치아 파절이 발생했을 때, 치아를 탈구시켜 즉시 정출시키는 외과적 정출술을 이용한 치관 연장술은 자연치를 보존하고 추가적인 치주적 수술 없이 단기간에 심미적인 보철 치료를 가능하게 한다. 본 환자는 16세 남환으로 본원 보존과로부터 상악 좌측 중절치의 심미 수복을 위해 본원 보철과로 의뢰되었다. 상악 좌측 중절치는 근관치료가 되어 있었으며 치관-치근 파절로 인해 협측 치관 길이는 4mm였으며 구개측 판막을 열었을 때 근심 구개측 치경부 파절 범위는 치은 하방 3-4mm에 위치하였다. 외과적 정출술을 통한 치관연장술을 시행하였으며 경과 관찰 및 임시 치아의 단계를 거쳐 3개월 후에 전부 도재관으로 수복하여 만족할 만한 임상결과를 얻을 수 있었다.
