METHOD FOR CARRYING OUT PLASTIC REPAIR OF EXTERNAL ACOUSTIC DUCT WITH AURICULAR HIRCUS BEING FORMED Russian patent published in 2005 - IPC

Abstract RU 2255678 C1

FIELD: medicine.

SUBSTANCE: method involves cutting skin behind auricle rudiment and exposing mastoid process area. Antrum is opened in Chipault triangle with an exit to tympanic cavity of the middle ear. Bone portion of the external acoustic duct is formed in single-stage operation. To form hircus, cartilaginocutaneous flap on pedicle is cut out from upper pole of the auricle rudiment and placed in projection of acoustic duct beginning. The modeled hircus is fixed some distance forward from the external acoustic duct towards soft tissues of jaws. To cover the bone portion of the newly created external acoustic duct, skin flap on pedicle is cut out from the mastoid region. Sutures are placed between two formed parts of the acoustic duct along the cartilaginocutaneous flaps contact line. The auricle rudiment is mobilized and transferred backwards to a position closer approximating the physiological one.

EFFECT: accelerated treatment course.
