METHOD FOR CLOSING TYMPANIC MEMBRANE PERFORATION Russian patent published in 2015 - IPC A61F11/00 A61B17/00 A61L27/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to otorhinolaryngology, and can be used in myringoplasty, for repairing partially lost anatomic structures, such as tympanic membrane. The surgery is performed with local or general anaesthesia. A tympanic membrane defect is closed with a thinned prepared alloplant in the form of an allogeneic cartilage plate. Before implanting, the alloplant is fragmented up to 0.2-0.3 mm thick and 0.8-0.9 cm in diameter that is followed by placing the plate into a bottle with a fixing fluid. The final stage of the operation involves placing the alloplant on the edges of the tympanic membrane defect. The cartilage plate is supposed to be more by 1.0-1.5 mm in size with the plate edges to be ovelapped with the acoustic meatus skin. The acoustic meatus is packed.

EFFECT: method provides the reliable fixation of the alloplant, preventing its postoperative dislocation and retraction, audiological characteristics of the alloplant as close to the characteristics of the normal tympanic membrane as possible, the absence of implant rejection and pronounced immune response, proteolytic enzyme stability, necessary rigidity of the cartilage plate, reduced length of the intervention, the absence of a cosmetic auricle defect.
