OBJECTIVE To test the feasibility of laser tissue welding (LTW) in creating an endoscopic transluminal repair of esophageal perforation. STUDY DESIGN Animal model. SUBJECTS AND METHODS A diode laser was used to create an endoluminal rabbit esophageal perforation repair. Burst pressures were compared with open incision, external suture, and external laser-augmented suture closure. Comparison...

Furcal perforation is usually an undesired complication that can occur during preparation of endodontic access cavities or exploring canal orifice of multirooted teeth. Inadequacy of the repair materials has been a contributing factor to the poor outcome of repair procedures. On the basis of the recent physical and biologic property studies of the relatively new introduced mineral trioxide aggr...

Iatrogenic aortic valve injury during non-aortic cardiac surgery is an infrequent complication. regurgitation (AR) has been reported after mitral repair, septal myomectomy, closure of the ventricular defect, and atrial defect repair. Various causes have for AR surgery. Perforation leaflet a common cause AR. Other are tension retraction due to inadvertent suture placement. A few previous case re...

TMJ disc related diseases are difficult to be cured due to the poor repair ability of the disc. TMJ-SDSCs were ideal cell sources for cartilage tissue engineering which have been widely used in hyaline cartilage regeneration. Fibrin gel has been demonstrated as a potential scaffold for neocartilage formation. The aim of this study was to repair the TMJ disc perforation using fibrin/chitosan hyb...

Anasal septal perforation is a defect in any portion of the cartilaginous or bony septum with no overlying mucoperichondrium or mucoperiosteum on either side. In the perforation, the mucosal edges epithelialize, preventing closure of the defect. Although some patients may be completely asymptomatic, symptoms can arise from altered nasal laminar airflow, and they may be severely disturbing to pa...

PURPOSE The present study compared the regenerative outcome of sinus graft procedures in a group of patients who underwent the repair of an intraoperatively diagnosed sinus membrane perforation to that of a group of patients without sinus membrane perforations. MATERIALS AND METHODS A sinus floor augmentation procedure was performed in 73 sinuses in 63 patients. In 28% of these sinuses a sign...

OBJECTIVES This study aims to report our experience on surgical repair of nasal septal perforations (NSP) using bilateral intranasal advancement/rotation flaps with open septoplasty technique. PATIENTS AND METHODS Medical records of 28 consecutive patients who were operated for NSP in our clinic between January 2009 and February 2013 were retrospectively analyzed. Demographic features of the ...

esophageal perforation continues to be a difficult diagnostic and management problem. recommendations regarding treatment remain controversial. 17 patients with perforation of the esophagus were retrospectively reviewed at the thoracic surgery unit of imam khomeini hospital between 1981 and 1992. the majority of the injuries involved the thoracic esophagus (10 or 59%), followed by the cervical ...

UNLABELLED A 51-year-old male with known osteogenesis imperfecta (OI) (type 1) presented with symptoms and signs of infective endocarditis. Transthoracic echocardiography showed chordal rupture and free mitral regurgitation, resulting in an emergency mitral valve repair. The surgical procedure was largely uneventful but subsequent clinical course on the intensive care unit was complicated by bo...

Subclavian artery (SCA) perforation is a rare complication while performing SCA intervention. In our present report, a 73-year-old female, with stenosis of the left SCA and situs inversus, presented with exercise-induced left arm weakness. The SCA stenosis was treated with direct stenting with a balloon-expansible Express LD 10×25 mm stent. However, it caused iatrogenic SCA perforation and hemo...
