Audiology Grand Rounds at Henry Ford Hospital: Diagnostics

---

1.  Patient A was eventually diagnosed with which condition? NF type 1 NF type 2 Idiopathic MS

2.  Neurofibromastosis type 2 is responsible for approximately what percentage of acoustic tumors? 5% 20% 40% 80%

3.  “Rollover” is often consistent with which of the following? Conductive hearing loss Sensory hearing loss caused by loss of outer hair cells Retrocochlear dysfunction All of the above.

4.  Considering the age of patient B (25 years), which treatment option would typically be advocated? Surgery to remove the tumor because they are considered to be more virulent in younger people Stereotactic radiosurgery because the patient’s age makes them a poor candidate for traditional surgery Watchful waiting with serial MRIs because vestibular schwanommas are typically slow growing and will not likely have a negative impact on a patient of this age None of the above

5.  Otosclerosis is the likely cause of this hearing loss in patient C as evidenced by which of the following? Absent acoustic reflexes in the presence of normal tympanogram Mixed hearing loss Family history and onset of symptoms associated with pregnancy All of the above

6.  Which of the following has been found to be true of the otoscerlosis? There is little to know evidence for genetic causes of otosclerosis Genetic causes can be found in at least half of otosclerosis cases Otosclerosis has the same prevalence regardless of race or location of origin The mode of inheritance of otosclerosis is well understood

7.  Otosclerosis is: More common in males More common in females Found in the same proportions among genders More common in children

8.  High-dose oral steroids are often used as a treatment for idiopathic sudden sensorineural hearing loss. According to a recent double-blinded study, steroid treatment yielded: better results than no treatment poorer results than no treatment approximately the same results as no treatment uninterpretable outcomes

9.  The authors of the aforementioned study mentioned in the previous question also found that which of the following was associated with recovery from idiopathic sudden sensorineural hearing loss? Presence of tinnitus Absence of tinnitus Presence of vertigo symptoms Absence of vertigo symptoms

10.  Mahmud et al. found that acoustic neuromas: may cause degenerative changes in the cochlea are much more common than previously believed do not cause sudden hearing loss all of the above
