Diseases of the Salivary Glands Flashcards
What nerve provides parasympathetic innervations to the submandibular glands?
Chorda tympani nerve
What nerve provides parasympathetic innervation to the Parotid glands?
CN IX: Glossopharyngeal
What nerve provides parasympathetic innervation to the sublingual gland?
Chorda tympani nerve
MC parotid abnormality associated with HIV
Diffuse lymphoepithelial cystic disease
MC benign salivary gland tumor
pleomorphic adenoma
MC malignant salivary gland tumor
mucoepidermoid carcinoma
What needs to be worked up if you find a cystic parotid mass?
HIV work up for diffuse lymphoepithelial cystic disease
What is the diagnostic test of choice for Sjogrens?
Minor salivary gland biopsy
- 3-5 glands from the lower lip
- look for lymphocytic infiltration
Which benign salivary gland tumor can present bilaterally?
Warthin’s tumor (10% of the time)
Which malignant salivary gland tumor can present bilaterally?
Acinic cell
What is the initial work up for salivary gland mass?
FNA biopsy + CT (or MRI)
sometimes CT + MRI can be helpful in making diagnosis
Name 7 high risk features that are indications for postoperative radiotherapy of a parotid neoplasm?
- High grade tumor
- Gross or microscopic residual disease
- Lymph node metastasis
- Extraparotid extension
- Tumors involving facial nerve CNVII
- Some deep lobe cancers
- Recurrent disease
Frey’s syndrome?
Gustatory sweating of the skin overlying the surgical site of the parotidectomy.
-Caused by parasympathetic nerves growing into the superficial sweat glands postoperatively.
How do you treat Frey’s syndrome?
- Botox injections
- topical antiperspirants
- Jacobson’s neurectomy
Should neuromuscular blockade be utilized during parotid surgery?
NO, you need to be able to stimulate the facial nerve once it has been anatomically identified.
