Preobrazhensky Modification of Stapedectomy

Preobrazhensky modification of stapedectomy (PMST) is a surgical procedure that is used to treat diseases of the middle ear and labyrinth. It was developed by Soviet otorhinolaryngologist Nikolai Aleksandrovich Preobrazhensky in the 1970s.

PMST is one of the most common operations in otorhinolaryngology. It involves removing part of the stapes, which is part of the hearing aid. The operation is performed under general anesthesia and takes about 40 minutes.

Benefits of PMCT include improved hearing, reduced tinnitus, and a reduced chance of complications such as infection or bleeding. Additionally, the surgery can be performed as an outpatient procedure, making it more convenient for patients.

However, like any other surgical procedure, PMCT has its risks and limitations. Some patients may experience pain, discomfort, or dizziness after surgery. There is also a chance of complications such as bleeding, infection, or nerve damage.

In general, PMST is an effective and safe method for treating middle ear diseases. However, before carrying out it, it is necessary to conduct a thorough examination and consultation with an otolaryngologist.

Introduction: **Modified stapedectomy** is an operation to remove part of the stapes to treat progressive hearing loss. To change the direction of the bone and other cartilaginous structures, a modified version of the operation is used, proposed by Professor Evgeniy Aleksandrovich Preobrazhensky in the USSR.

Description of technology: The modification is as follows:

1. Removal of the stapes is carried out while preserving the sutures of the lower petrosal wall. 2. Resection of the stapes does not reach the site of formation of the bone plate. 3. Replacement in the area where the bone plate is created is performed with a bone frame. In this way, optimal pressure is maintained on
