Human amniotic membrane as a homograft material was compared to temporalis fascia to close tympanic membrane perforations in 50 patients with chronic otitis media. Human amniotic membrane was used in 20 patients while temporalis fascia was used in the remaining 30. Anatomical closure of the perforation and reduction of the air-bone gap was measured. The graft uptake showed a 65% success rate fo...

The aim of this study was to clarify whether hydroxyapatite/collagen composite material (HAp/Col) could be useful as a graft for maxillary sinus floor augmentation (MSFA). MSFA and implant placement were performed simultaneously. When the lateral approach employed, 3 out 19 implants failed in sinuses (success rate; 84.2%), these cases alveolar bone heights, cortical thicknesses values stability...

introduction: tympanoplasty is a standard procedure to repair tympanic membrane perforation. the aim of this study is to evaluate the results of tympanoplasty (hearing improvement and tympanic membrane closure rate) in patients suffering from chronic perforation of the tympanic membrane by considering the prognostic factors.  materials and methods: in a prospective study, based on the results o...

BACKGROUND Burns are among the most devastating forms of injury. Nowadays the standard treatment for deep partial thickness and full-thickness burn is early excision and grafting, but this technique is not always feasible; and this leads to chronicity and microbial colonization of burn wounds. Interesting properties of human amniotic membrane made us use it in management of chronic infected bur...

Many cultivars of ornamental conifers are difficult to propagate. Cuttings may root poorly and graft success may be highly variable even in the hands of skilled, experienced propagators. Because of these problems, we conducted a detailed study of the physiology of graft formation in Picea pungens 'Hoopsi' scions grafted on Picea abies rootstocks with the purpose of identifying factors limiting ...

Abstract Background This study aims to compare the graft uptake rate and hearing improvement of fat versus inlay butterfly tragal cartilage in repair perforations chronic otitis media mucosal adults. In this retrospective study, twenty-eight patients were included with small dry anteroinferior tympanic membrane (less than 1/3 membrane). The age range was 18 44 years old. Myringoplasty done unde...

OBJECTIVE To compare long- term outcomes of buccal mucosa graft (BMG) augmentation urethroplasty for long segment bulbar urethral strictures done by placing the graft ventrally, dorso-laterally and dorsally. MATERIAL AND METHODS We conducted a single institution retrospective study on 112 who underwent BMG augmentation urethroplasty for non-traumatic bulbar urethral strictures between January...

INTRODUCTION For dorsal onlay graft placement, unilateral urethral mobilization is less invasive than standard circumferential urethral mobilization. Apart from success in terms of patency of urethra, other issues like sexual function, overall quality of life and patient satisfaction remain important issues while comparing outcomes of urethroplasty. AIM To prospectively compare the objective ...

Abstract Background Temporalis fascia and perichondrium are still the most successful graft materials for primary microscopic repair of tympanic membrane perforations worldwide with 80% to 90% success rate. However, minimally invasive surgery is becoming standard in many fields endoscope has been largely incorporated ear over past 10 years. This study aimed evaluate rate endoscopic transcanal c...

BACKGROUND The purpose of this report was to analyze the results obtained from a group of interventional nephrologists working in multiple centers performing basic procedures that are used routinely in the management of vascular access problems, with an effort toward establishing standards for evaluating success, complication rates, and acceptable times for procedure duration and fluoroscopy. ...
