OBJECTIVE The goal of this study was to evaluate the effects of perforation edge approximation and direct application of basic fibroblast growth factor (bFGF) each alone on the healing of large traumatic tympanic membrane perforations with inverted edges in humans. STUDY DESIGN Prospective, sequential allocation, three-armed, controlled clinical study. SETTING University-affiliated teaching...

Septal perforations are difficult problems that the otolaryngologist has to solve. In fact, the otolaryngologist has to identify the cause, which in most cases is either iatrogenic or idiopathic, to decide upon the need for surgery, and select the most suitable surgical technique of those currently available, for the case under consideration. All surgical procedures, aimed at repair of nasal se...

PURPOSE Nephrostomy tube insertion and/or a ureteral stent placement is advised when pelvi-calyceal perforations are encountered during percutaneous nephrolithotomy (PNL) nevertheless totally tubeless PNL is a possible exit strategy in percutaneous renal surgery therefore case series on the short term clinical outcomes of noninvasive management of iatrogenic pelvicalyceal perforations encounter...

PURPOSE To study the predisposing conditions, treatments, and visual outcomes of nontraumatic corneal perforations. METHODS A retrospective chart review was conducted of all nontraumatic corneal perforations seen between January 1992 and December 1998, with > or = 3 months of follow-up, at the Cornea Service Wills Eye Hospital. RESULTS A total of 40 nontraumatic corneal perforations was ana...

DA Esophageal perforations can generally be classified as iatrogenic or idiopathic. Iatrogenic perforations are usually caused by gastroenterologists or surgeons performing endoscopy who inadvertently perforate the esophagus over the course of the procedure. Iatrogenic perforations can occur via a variety of other means, including when a nasogastric or feeding tube placement goes wrong or, less...

Glove perforation during surgery has always been a matter of concern as it increases the infection rate and the risk of transmission of blood borne diseases. To determine the common causes, the site and the awareness of glove perforations in orthopaedic surgery, a prospective study was conducted to assess the rate of glove perforation during 130 consecutive orthopaedic operations. All gloves wo...

OBJECTIVE In open lung surgery the surgical access is encircled by the ribs, which should result in a high glove perforation rate compared with other surgical specialities. METHODS Prospectively the surgeon, first and second assistant and the scrub nurse wore double standard latex gloves during 100 thoracotomies. Parameters recorded were: procedure performed, number of perforations, localizat...

introduction : furcal perforations are one of the most challenging causes of endodontic failures. several materials including mta have been used for non surgical repair of these perforations. the aim of this study was to compare treatment outcome of furcal perforation treatment in primary molars using root mta and proroot mta. materials and methods: this in vitro study was conducted on 54 prima...

normal 0 false false false en-us x-none ar-sa background: considering the presence of squamous epithelial cells and fibroblasts in the tympanic membrane (tm), topical estrogen application may influence the repair of tm perforations. therefore, this study was designed to investigate the healing effect of topical estrogen on chronic tm perforations and improvement in hearing threshold. materials ...

statement of problem: perforations are significant complications that can occur during root canal therapy and may result in the destruction of adjacent periodontal tissues. an ideal material for repairing a perforation should be biocompatible and have a high sealing ability. purpose: the aim of this study was to compare histologic tissue responses of experimentally induced pulp chamber perforat...
