Answers:
Wave II in the following image corresponds to signal transduction through what structure?
A) Lateral lemniscus
B) Brainstem
C) Cochlear Nucleus
D) Peripheral CNVIII
E) Central CNVIII
This image represents a normal ABR.
Wave I – generated by the peripheral portion of cranial nerve VIII
Wave II – generated by the central portion of cranial nerve VIII
Wave III – generated by the cochlear nucleus
Wave IV – generated by the superior olivary complex/lateral lemniscus
Wave V – generated by the lateral lemniscus/inferior colliculus
What is the primary use of CHAMP?
Cochlear Hydrops Analysis Masking Procedure is used primarily for detecting Meniere disease.

Quick Facts:
Perichondritis of Auricle
-Often due to trauma (wrestling, lac or ear piercing)
-Infections perichondritis most often due to pseudomonas.
-Treat w/ I&D and/or Abx.
-May involve ear lobule.
-Can also be caused by inflammatory process = relapsing polychondritis.
-Associated with other autoimmune diseases and involves cartilages of nose, neck and chest.
-Treat w/ steroids/pain control.
-Ear lobule not involved in relapsing polychondirits.
