Left sinus of Valsalva aneurysm(SVAn)is a very rare clinical entity. We present a 68-year-old female with left SVAn, 5 cm in diameter, compressing the left main coronary artery and causing antero-septal asynergy. She also had massive pericardial effusion, moderate to severe(grade Ⅲ)aortic regurgitation, and mitral regurgitation. One month after pericardial drainage, the patient successfully underwent composite graft replacement of the aortic root, reimplantation of the right coronary artery and suture closure of thin friable left main trunk(LMT)orifice, as well as double coronary artery bypass grafting with bilateral internal mammary arteries to the left anterior descending artery and the diagonal branch...

Intraventricular conduction abnormalities following cardiac surgery have been thoroughly described, especially after valvular surgery. It is also widely known that several anesthetic factors can cause autonomic disturbances resulting in the unmasking of sinus node dysfunction, significant bradycardia, and cardiovascular collapse during the intraoperative period. However, little is known about asymptomatic episodes, especially those occurring prior to coronary artery bypass grafting (CABG). We report a rare occurrence of an intraventricular conduction defect that presented in an asymptomatic patient following non-ST-elevation myocardial infarction prior to urgent CABG...

BACKGROUND: A sinus floor augmentation may be indicated when a lack of hard tissue impedes implant placement. Although clinically successful, evidence supporting the long-term three-dimensional stability of the grafted volume is scarce. Second, evidence on the patient's acceptance of this type of treatment is limited. PURPOSE: First is to evaluate the changes in graft volume after lateral wall sinus lifting based on superimposed cone beam computed tomography (CBCT) images and then to assess patient-reported outcome measures (PROMs) and clinical outcomes...

BACKGROUND: After tooth loss, the posterior maxilla is usually characterized by limited bone height secondary to pneumatization of the maxillary sinus and/or collapse of the alveolar ridge that preclude in many instances the installation of dental implants. In order to compensate for the lack of bone height, several treatment options have been proposed. These treatment alternatives aimed at the installation of dental implants with or without the utilization of bone grafting materials avoiding the perforation of the Schneiderian membrane...

The orbito-zygomatic complex (OZC) includes several key structures, and its destruction leads to the impairment of functional activities such as nutrition, communication, nasal support, and vision. Management of benign tumors of the OZC is therefore a surgical challenge because of the necessity for reconstruction of these elements. Autogenous bone is considered the gold standard for reconstruction. Nevertheless, there is difficulty related to the complex anatomy and distorted skeletal anatomic landmarks, which require precise work in the case of bone grafts...
