The translabyrinthine approach was developed by William F. House, M.D., [2] who began doing dissections in the laboratory with the aid of magnification and subsequently developed the first middle cranial fossa and then the translabyrinthine approach for the removal of acoustic neuroma.
A vestibular schwannoma (VS), also called acoustic neuroma, is a benign tumor that develops on the vestibulocochlear nerve that passes from the inner ear to the brain. The tumor originates when Schwann cells that form the insulating myelin sheath on the nerve malfunction. Normally, Schwann cells function beneficially to protect the nerves which ...
For patients with NF2, the surgeon will spend a significant amount of time removing the acoustic neuroma tumours before inserting the implant. Depending upon the surgical approach, this may involve sacrificing the auditory nerve, thus rendering the patient deaf. [ 3 ]
Acoustic neuroma (vestibular schwannoma) – benign neoplasm of Schwann cells affecting the vestibulocochlear nerve; Meningioma – benign tumour of the pia and arachnoid mater; Ménière's disease – causes sensorineural hearing loss in the low frequency range (125 Hz to 1000 Hz).
The Acoustic Neuroma Association recommends that cell phone users use a hands-free device. Meningiomas are significantly more common in women than in men; they are most common in middle-aged women. Two predisposing factors associated with meningiomas for which at least some evidence exists are exposure to ionizing radiation (cancer treatment of ...
radiotherapy or surgical excision of vestibular schwannoma or acoustic neuroma, though, in most cases, it is unlikely that hearing will be preserved; Stapedectomy and stapedotomy for otosclerosis - replacement or reshaping of the stapes bone of the middle ear can restore hearing in cases of conductive hearing loss
Acoustic neuroma - a slow-growing, benign tumor of the acoustic nerve. [2] Symptoms, which most often start after the age of 30, can include dizziness, headache, vertigo, loss of balance, ringing sensations, and numbness. [3] Ganglioneuroma - a tumor of the sympathetic nerve fibers arising from neural crest cells. [4]
Acoustic neuromas are non-cancerous tumors. [90] They can be treated with surgery, radiation therapy, or observation. Early intervention with surgery or radiation is recommended to prevent progressive hearing loss. [91]
