Purpose: Soft tissue recessions frequently cause esthetic disharmony and dissatisfaction. Compared with soft tissue coverage around a tooth, the coverage of an implant site is obviously unpredictable. Particularly in the cases of thin mucosa, a significant greater amount of recession takes place compared to thick mucosa. To overcome this problem, this case report demonstrates a two-step mucosal dehiscence coverage technique for an endosseous implant. Methods: A 33-year-old female visited us with the chief complaint of dissatisfaction with the esthetics of an exposed implant in the maxillary left cental incisor region. A partial-thickness pouch was constructed around the dehiscence. A subepithelial connective tissue graft was positioned in the apical site of the implant and covered by a mucosal flap with normal tension. At 12 months after surgery, the recipient site was partially covered by keratinized mucosa. However, the buccal interdental papilla between implant on maxillary left central incisor region and adjacent lateral incisor was concave in shape. To resolve the mucosal recession after the first graft, a second graft was performed with the same technique. Results: An esthetically satisfactory result was achieved and the marginal soft tissue level was stable 9 months after the second graft. Conclusions: The second graft was able to resolve the mucosal recession after first graft. This two-step approach has the potential to improve the certainty of esthetic results.

Posterior transarticular screw fixation for atlantoaxial instability due to trauma or rheumatoid arthritis provides immediate rigid fixation of the C1-2 vertebral segment while preserving motion between the occiput and C1. This technique provides more resistance to translational and rotational forces than wiring technique. However, the technique of transarticular screw fixation is inherently demanding because of the complex anatomy of the occipitocervical region and vertebral artery(VA) at risk for arterial damage. VA injury may lead to serious subsequent neurological deficits and possibly death from bilateral VA injury. We report a case of a vertebral artery-to-epidural venous plexus fistula after posterior transarticular screw fixation which was treated with balloon occlusion.

Purpose: This case report discusses the effect of a root submergence technique on preserving the periodontal tissue at the pontic site of fixed dental prostheses in the maxillary anterior aesthetic zone. Methods: Teeth with less than ideal structural support for fixed retainer abutments were decoronated at the crestal bone level. After soft tissue closure, the final fixed dental prostheses were placed with the pontics over the submerged root area. Radiographic and clinical observations at the pontic sites were documented. Results: The submerged roots at the pontic sites preserved the surrounding periodontium without any periapical pathology. The gingival contour at the pontic site was maintained in harmony with those of the adjacent teeth, as well as the overall form of the arch. Conclusions: The results of this clinical report indicate that a root submergence technique can be successfully applied in pontic site development with fixed dental prostheses, especially in the maxillary anterior esthetic zone.

Flabby tissue is not rare for denture wearers. Mucostatic impression technique is necessary due to compromised retention and stability of denture resulting from distortion of mobile flabby tissue. In this report, individual tray was fabricated by model-scanning and 3D printing treatment denture. And then, mucostatic impression for flabby tissue was obtained by using individual tray modified with window technique. Definitive denture was fabricated based on information of treatment denture including incisal pontic arrangement, jaw relationship and occlusion.

Untreated severe tricuspid regurgitation (TR) is associated with poor outcomes. Functional TR occurs secondary to dilatation of the annulus and tethering of the leaflets. Ring annuloplasty alone can correct most cases, but is insufficient in cases of severe annular dilatation due to severe leaflet tethering. In such cases, a tricuspid edge-to-edge technique may be an option. However, stitching of the leaflet tips alone is likely to result in tearing of the leaflets. Approximation of the durable chordae tendineae is considered helpful for this problem. Herein, we present the case of a 39-year-old man who had undergone open-heart surgery for acute type A aortic dissection 13 months earlier. A right mini-thoracotomy approach with a beating-heart strategy was used, which did not require unnecessary pericardial adhesiolysis and dissection. This technique had the advantage of reducing the operation time and the risk of bleeding. To summarize, we present a case of tricuspid valve repair in a high-risk patient with severe leaflet tethering that was successfully managed using these methods.

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare condition characterized by nodular lesions predominantly in the head and neck region, often causing discomfort or pain. Treatment remains challenging because of its rarity and the lack of established guidelines. This report presents a case of ALHE affecting the earlobes that was successfully managed using ear lobule reduction surgery and subsequent intralesional steroid injections. A 31-year-old woman with a history of recurrent earlobe masses underwent a partial excision to avoid the loss of the earlobe. Histopathological examination confirmed Kimura disease, a variant of ALHE. Subsequent local methylprednisolone injections effectively controlled the remaining lesions, resulting in significant size reduction without notching. Various treatment modalities have been attempted for this condition; however, recurrence rates remain high. Surgical resection combined with intralesional corticosteroid injections is the preferred approach. In this case, a sub-antitragal groove technique for earlobe reduction was employed to preserve the lateral edge of the ear lobule, minimize the risk of deformity, and achieve a predictable outcome. The sub-antitragal groove technique offers an approach to reduce earlobe size without compromising aesthetics. Further research is required to elucidate the pathogenesis of ALHE and establish standardized treatment protocols for this rare condition.

Tooth autotransplantation using socket lifting like this case had been seldom reported. So this report demonstrates a case using this technique which is frequently used for maxillary posterior implantation. Clinical considerations and pitfalls will be discussed.

This report describes a month-old female infant with a rare supracardiac type of total anomalous pulmonary venous connection which have intrapulmonary drainage and small left atrium. The left pulmonary vein drained into right hilum via transverse common pulmonary vein, and then both pulmonary veins drained into superior vena cava via ascending connecting vein. This anomaly was sucessfully repaired by double patch technique.
