MC cause of conductive and SN hearing loss
conductive: ceruman impaction
SN: prebycusis
damaged ossicle, mastoiditis, OM, FB, ETD, secondary to URI, Perf TM, fluid, otosclerosis, cholesteatoma, tumors
causes of conductive HL
CNS lesion, neuro d/o, aminoglycosides, loops, meniere, neuroma, labyrinthitis, infection
causes of SN HL
vertigo
SE of reglan, promethazine
extrapyramidal, tardive dyskinesis, dystonia, parkinsonism
dangers of dopamine blockers
reglan, promethazine
neuroleptic malignant syndrome
Neuro leptic malignancy syndrome
stop dopamine blocker

Can lead to cholesteatoma.
avoid what
