METHOD FOR SURGICAL TREATMENT OF ISOLATED ANOMALY OF THE DEVELOPMENT OF THE MIDDLE EAR Russian patent published in 2021 - IPC A61F11/00 A61B17/00 

FIELD: medicine; otorhinolaryngology.

SUBSTANCE: behind-the-ear incision with transmeatal access is performed. A checkup of the tympanic cavity and an assessment of the condition of auditory ossicles and the partial atretic plate are carried out. The atretic plate and the lateral wall of the attic are removed. The mobilization of the auditory ossicle chain is carried out, a gap between auditory ossicles and the bone tympanic ring of at least 1.5 mm is formed. A meatotimpanal flap is placed into position with the closure of the tympanic membrane defect with an autofascial flap. Tamponade of the external auditory canal and suturing of the behind-the-ear wound are performed. After assessing the condition of auditory ossicles and the partial atretic plate, bone bridges that fix ossicles to the atretic plate are removed using an instrument: a curette or a hook. After that, a fibrous layer and the mucous membrane are separated from the medial surface of the partial atretic plate until the latter is removed. After removing the atretic plate, an elongated hammer handle is partially resected. The use of protectors that protect the auditory ossicles is carried out. After that, a hollow above the projection of the bone tympanic ring is formed using boron. Then, protectors are removed. A silastic fragment is placed on the bone tympanic ring opposite the end of the hammer handle.

EFFECT: method makes it possible to increase the efficiency of hearing-improving operations in patients with isolated anomaly of the development of the middle ear and the presence of the partial atretic plate, reduce the traumaticity of the operation and prevent the refixation of the auditory ossicles.
