Vestibular nerve section, performed via a translabyrinthine approach, is a surgical procedure aimed at alleviating severe recurrent episodes of vertigo. This condition can significantly impact a patient's quality of life, leading to debilitating symptoms that may not respond to conservative treatments. The procedure involves a meticulous surgical technique that begins with a C-shaped incision made above the ear, extending around the back of the ear. This incision allows access to the mastoid bone, where a complete mastoidectomy is conducted using specialized high-speed drills and various burs to remove bone and create a clear pathway to the inner ear structures. The surgery entails careful dissection to expose critical anatomical landmarks, including the facial nerve, the internal auditory canal, and the vestibular nerves. The goal of the procedure is to section the superior and inferior vestibular nerves, which are responsible for transmitting balance information to the brain, thereby interrupting the pathways that contribute to vertigo. The surgical site is then irrigated, and the incision is closed in layers to promote healing and minimize complications.
