To be used as a temporary dressing in the external auditory canal following tympanoplasty or stapedectomy procedures.
The OTOSILK™ Graft Dressing is a sterile, disposable graft dressing constructed of non-adherent material, designed for use with split thickness skin grafts used in procedures such as tympanoplasty, canalplasty, mastoid tympanoplasty, correction of congenital aural atresia, and removal of canal exostoses.
Split thickness skin grafts may be taken from several sites, using either a razor blade or dermatome. The OTOSILK dressing will be used as a carrier for this skin graft to the ear canal. The graft is placed dermis side up on the dressing and the uncovered material is trimmed away. The skin graft and dressing are then applied to the canal. The dressing is removed from the canal one to two weeks post-operatively. The blue color of the OTOSILK Graft Dressing increases visualization of the dressing, ensuring total removal from the ear canal without disturbing the graft.

(a)
Identification. An occlusive wound dressing is a nonresorbable, sterile or non-sterile device intended to cover a wound, to provide or support a moist wound environment, and to allow the exchange of gases such as oxygen and water vapor through the device. It consists of a piece of synthetic polymeric material, such as polyurethane, with or without an adhesive backing. This classification does not include an occlusive wound dressing that contains added drugs such as antimicrobial agents, added biologics such as growth factors, or is composed of materials derived from animal sources.(b)
