9 Questions
What is the most likely mechanism for the man's xerostomia?
Decrease in mucin concentration associated with CN IX damage
What is the clinical manifestation of this man's xerostomia?
Low saliva volume and high viscosity
Which nerve is likely implicated in the development of the man's xerostomia?
CN IX (Glossopharyngeal nerve)
What is the most likely cause of the man's xerostomia following radiation treatment?
Decrease in mucin concentration associated with CN IX damage
What is the role of the glossopharyngeal nerve (CN IX) in the development of xerostomia following radiation treatment?
Activation of salivary glands
How does radiation treatment likely affect the salivary glands, leading to xerostomia?
Stimulation of glossopharyngeal nerve (CN IX) activity causing a decrease in mucin concentration
What is the most likely mechanism for the man's xerostomia?
Decrease in mucin concentration associated with CN IX damage
Which nerve damage is most likely responsible for the development of the man's xerostomia?
CN IX damage
What is the role of sympathetic nerve damage in the development of xerostomia?
Increases water concentration in saliva
