The present study reviewed the prevalence of postoperative facial palsy after removal of large vestibular schwannoma using translabyrinthine approach microsurgery, predictive factors of postoperative facial palsy, tumor control, and the extent of internal acoustic meatus tumor removal.Ī retrospective review of patients’ medical records was conducted at the department of otorhinolaryngology–head–neck surgery and neurosurgery in a tertiary referral center. Therefore, the present study investigated predictive factors for tumor control. However, the tumor remnant should be monitored by regular imaging and controlled with radiosurgery if there is a significant progression in tumor size. The modern concept of facial nerve preservation with subtotal and near-total resection is generally established and well understood, and residual tumor has been deemed to be acceptable. Surgery aims to completely remove the tumor and minimize complications in patients with acoustic neuroma. There are few reports discussing the extent of internal acoustic meatus tumor removal. Larger tumor size with greater possibility of internal acoustic meatus involvement may affect the surgical outcome. Given the functional and cosmetic effects of facial nerve dysfunction, it is important to determine the perioperative factors that influence the preservation of facial nerve function. Since then, patient morbidity and mortality rates have reduced due to a gradual refining of the approach technique. In 1894, Sir Charles Ballance was the first to successfully resect an acoustic neuroma. Suitable management for each individual case involves careful consideration of factors including patient age, health status, tumor size and location, residual hearing in both ears, and neurological symptoms due to tumor compression.
Due to the characteristics of these tumors, the routine treatment protocols are observation, stereotactic radiotherapy, and surgical intervention including the middle cranial fossa approach, suboccipital/retrosigmoid approach, and translabyrinthine approach. Vestibular schwannoma, also known as acoustic neuroma, is the most commonly reported type of cerebellopontine angle tumor. Most tumors in the cerebellopontine angle are benign and slow-growing.
