Our extra-scalar operating method of cochlear implantation. Experience with 46 cases

Area of Science:

• Neurosurgery
• Otolaryngology
• Biomedical Engineering

Background:

• Cochlear electrode placement traditionally involves invasive procedures.
• Minimally invasive techniques are sought to reduce surgical risks and improve patient outcomes.
• Accessing the cochlea requires precise surgical navigation.

Purpose of the Study:

• To develop a novel surgical method for cochlear electrode implantation.
• To enable electrode placement without opening the tympanic cavity or vestibule.
• To utilize the medial wall of the tympanic cavity as a primary surgical access point.

Main Methods:

• Surgical technique focusing on accessing the cochlea via the medial tympanic cavity wall.
• Utilizing the bony cochlear wall for electrode insertion.
• Developing an operating method for minimally invasive electrode placement.

Main Results:

• The medial wall of the tympanic cavity provides a favorable surgical access route.
• The proposed method allows for electrode placement without opening the scale tympani or vestibule.
• Surgical access to the cochlea is adequate using this approach.

Conclusions:

• A new, less invasive surgical method for cochlear electrode placement has been elaborated.
• The medial cochlear wall is a viable and accessible surgical target for electrode insertion.
• This technique offers a promising alternative for cochlear implant procedures.
