What You Need to Know About PSOM
All that cavalier owners need to know about primary secretory otitis media (PSOM)
Primary secretory otitis media (PSOM) has become more frequently diagnosed in cavalier King Charles spaniels. It consists of a highly viscous mucus plug which fills the dog’s middle ear and may cause the tympanic membrane to bulge. PSOM has been reported almost exclusively in cavaliers.
Because the pain and other sensations in the head and neck areas, resulting from PSOM, are similar to some symptoms caused by syringomyelia (SM), some examining veterinarians may have mis-diagnosed SM in cavaliers which actually have PSOM and not SM.
