Best Doctor List Near You for Acoustic Neuroma (vestibular Schwannoma) Surgery in Shahr e bozorg

Acoustic neuroma, also known as vestibular schwannoma, is a benign tumor that develops on the vestibulocochlear nerve, which is responsible for hearing and balance. This condition arises from Schwann cells, which produce the myelin sheath that insulates nerve fibers. Although these tumors are generally slow-growing and non-cancerous, they can lead to significant complications due to their location near the brainstem and cerebellum. As the tumor enlarges, it can cause hearing loss, tinnitus (ringing in the ears), and balance difficulties. Surgical intervention is often considered when the tumor significantly affects a patient's quality of life, if there is a rapid growth noted on imaging, or if neurological deficits arise. The choice of surgical approach depends on various factors, including the size and location of the tumor, the patient's age and overall health, and their preferences regarding the potential risks and benefits. The most common surgical techniques include the translabyrinthine approach, retrosigmoid approach, and middle cranial fossa approach, each with distinct advantages and risks. The translabyrinthine approach is a common method for larger tumors and involves the removal of the inner ear structures to gain access to the tumor; while effective, this typically results in total hearing loss in the affected ear. The retrosigmoid approach, on the other hand, allows access to the tumor while preserving hearing in some cases, as it does not require removal of the inner ear structures; however, it is more technically challenging and carries a risk of complications such as cerebrospinal fluid leaks or facial nerve injury. The middle cranial fossa approach is less frequently used and is typically reserved for smaller tumors where hearing preservation is a priority. Regardless of the technique chosen, acoustic neuroma surgery aims to remove as much of the tumor as possible while minimizing damage to surrounding structures, particularly the facial nerve, which can result in facial weakness or paralysis if injured. Post-operatively, patients often require rehabilitation, particularly if balance difficulties are present or if the facial nerve has been compromised, leading to facial asymmetry or weakness. Hearing rehabilitation, such as the use of hearing aids or cochlear implants, may also be necessary depending on the extent of hearing loss. Overall, the choice for surgery and the selected approach are determined through a detailed discussion between the patient and a multidisciplinary team consisting of neurosurgeons, otologists, and radiation oncologists. The decision is primarily influenced by the tumor characteristics, the patient's symptomatology, and their functional status, ultimately aimed at enhancing the patient's quality of life while minimizing risks. Following surgery, regular follow-up imaging and evaluations are standard to monitor for any potential recurrence or complications, ensuring the best possible outcome for individuals affected by this condition.
