METHOD FOR OPERATION FOR CHRONIC TUBOTYMPANIC PURULENT OTITIS MEDIA Russian patent published in 2023 - IPC A61F11/20 A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, in particular to otorhinolaryngology. Access to the middle ear is performed with mobilization of the external auditory canal. At the same time, a skin incision is made along the entire length of the behind-the-ear fold. The soft tissues of the behind-the-ear region are dissected in layers to the bone, exposing the site of the mastoid process. The skin of the posterior, upper and lower walls of the external auditory canal is separated anteriorly along the entire length until the tympanic ring is reached. Then, a vertical skin incision of the posterior wall of the external auditory canal is made in the middle of the bone section of the external auditory canal, 1.0 cm long. Traction of the auricle is performed together with the skin of the posterior wall of the external auditory canal anteriorly, fixing the free ends of the silicone strip with a clip on the surgical underwear used to drape the surgical wound. Using a power tool equipped with a diamond cutter, the cortical layer of the posterior bone wall of the external auditory canal is removed until the anterior meatotympanic angle is visualized, creating a remodeled plane of the posterior bone wall of the external auditory canal. Next, the meatotympanic flap is mobilized by dissecting the tympanic ring from 6 to 1 hour clockwise for the right ear, or from 6 to 11 hours counterclockwise for the left ear. Then, after performing tympanoplasty, the placement of the graft used for plastic replacement of the tympanic membrane defect is controlled. After that, the edges of the skin incision of the external auditory canal are compared. A silicone protector is placed over the incision area. Then the surgical access is closed.

EFFECT: method allows to improve visualization during revision of middle ear structures and control during tympanoplasty and placement of a plastic flap to close a tympanic membrane defect, increase the efficiency of treatment of patients with chronic otitis media.
