Injection laryngoplasty is a common operative technique used in the management of unilateral vocal fold paralysis. Cymetra is a micronized particulate injectable form of acellular human dermis that is commonly used for vocal cord medialization procedures. We report migration of an intracordal bolus of Cymetra into the medial wall of the pyriform sinus. Histopathology from endoscopic resection o...

Background: Recent studies indicate an increased incidence of pertussis disease in recent years. The aim of this study was to evaluate the efficacy of the acellular vaccine for children (as a replacement of current whole cell vaccine in the Expanded Program on Immunization) and for high-risk adults in Iran through updating current best available evidence.   Methods: We performed a syste...

BACKGROUND Dermal skin substitutes have become a standard of care in burn treatment. OBJECTIVE To compare and assess wound contracture reduction and histologic incorporation into the wound, dermal substitutes were implanted into full-thickness skin wounds in nude mice. MATERIALS AND METHODS Thirty-seven mice received a full-thickness 2 x 2 cm dorsal skin wound, and were either implanted wit...

BACKGROUND Posterior pharyngeal augmentation is a recognized treatment for velopharyngeal insufficiency in selected candidates. To date, however, the procedure has failed to gain widespread acceptance because of the absence of an implant material with sufficient safety, durability, and biocompatibility. In this study, the use of micronized acellular dermal matrix injection for augmentation of t...

We describe our initial experience with the novel application of processed human cadaveric allograft skin in reconstruction of a damaged corpus cavernosum associated with distal extrusion of a penile prosthesis. The material was evaluated for ease of reconstruction, adequacy of repair, and outcome. Human processed dermis allograft requires no intraoperative harvesting, is technically easy to fa...

introduction: to describe the underlay tympanoplasty technique using an acellular dermal graft(alloderm) for tympanic membrane (tm) reconstruction in a guinea pig model and to demonstrate the feasibility of the technique using alloderm tissue harvested from the prepuce as a source of tissue for future grafting in human tm reconstruction.   materials and methods: the prepuce was divided during c...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background : recently autologous fat tissue transfer has gained much popularity. on the other hand, applying the transferring methods with a higher survival rate is still controversial. the aim of this study is to compare dermis-fat graft and dermal-fascia-fat graft. methods : this animal study was conducted in 2008-2009. ...

Secondary cutaneous amyloidosis refers to clinically unapparent amyloid deposits within the skin in association with a pre-existing skin condition or skin tumors, such as basal cell carcinoma, porokeratosis, solar elastosis, Bowen's disease, and mycosis fungoides. A 70-year-old woman presented with a 6-month history of asymptomatic multiple yellowish plaques on both legs. She had been diagnosed...

INTRODUCTION Acellular dermal matrices have been used with increasing frequency in both reconstructive and cosmetic surgery. While many studies have described the safety and morbidity profiles of these materials, little is known about the relative mechanical properties of individual sheets of allograft harvested from distinct donors. METHODS Sixty-two individual sheets of an acellular dermal ...
