1ENT Department, Jordan University of Science & Technology, Irbid. khraistarek@hotmail.com
Objectives:
To study the effect of pre-operative hearing level and tumour size on the hearing outcome of hearing preservation surgery for vestibular schwannoma.
Study Design And Setting:
A review of literature conducted at Gruppo Otologico, a tertiary referral centre for neurotology and skull base surgery.
Results:
A total of 1993 patients in 16 publications addressing the topic of hearing preservation surgery in vestibular schwannoma were analysed. The American Academy of Otolaryngology-Head and Neck Surgery hearing classification system was the classification upon which we based our analysis.
Conclusion:
Defining hearing preservation as class-A hearing, there was a strong inverse relationship between pre-operative hearing and post-operative hearing levels and between tumour size and post-operative hearing levels.
