He made seminal contributions to hearing preservation acoustic neuroma
Hearing preservation in unilateral acoustic neuroma
is one of the risk factors of sudden sensorineural hearing loss (SSHL) (3-15%).
In the 1960s, the development of microscopes revolutionized the treatment of acoustic neuroma
. However, recent studies have shown that microsurgical tumor removal is associated with morbidity and a mortality rate reported to be 1% or less.
Brainstem tumors including gliomas and acoustic neuromas
can lead to central hypoventilation [5, 6].
Regarding the hearing loss and tinnitus, there was no remarkable response, and the explanation could be related to pressure due to pathology that cause an enhancing lesion in the internal auditory meatus involving the 7th-8th nerve complex most likely acoustic neuroma
Trigeminal neuralgia due to an acoustic neuroma
in the cerebellopontine angle.
A low risk association was found between GPX1 C > T polymorphism (rs1800668) with prostate cancer 8 while marginal association existed between GPX1 rs1800668 C > T polymorphism and risk of prostate cancer.9 A study was carried out in Chinese Han population that provides no association between C/T polymorphism in GPX-1gene (rs1800668) and susceptibility to noise-induced hearing loss.10 Similarly numerous studies were conducted for risk of Alzheimer's disease,11 for Kashin-Beck disease12 and risk of glioma, glioblastoma, meningioma, or acoustic neuroma
for GPX-1C/T polymorphism (rs1800668)13 and found no association for this polymorphism.
Eighteen (18) cases (69.23%) were acoustic neuroma
and 4 cases (15.38%) were meningioma, 3 cases (11.54%) were epidermoid and 1 case (3.85%) was arachnoid cyst.
Predicting long-term facial nerve outcome after acoustic neuroma
I was diagnosed in 1996 at age 53, but didn't have a major exacerbation until 2004, and since then have had several other issues like hydrocephalus, acoustic neuroma
and a heart attack, so my body isn't cooperating very well anymore.
