This is part two of my talk on swellings and lumps arising in the salivary gland tissue. It's Professor John Langdon once again. We'll start with management of salivary gland neoplasms.
I'm not, in this talk, talking very much about management of salivary gland diseases at all because it's not your remit but there are some important background points to make. This slide repeats what I've labored previously that the majority of tumors arise in the parotid and 75% of them are benign.
This slide is a specimen of superficial parotidectomy, and you're looking at the deep aspect. And you can see at the edge of the specimen is the normal healthy parotid tissue of the superficial lobe. Within that, you can see a benign pleomorphic adenoma which is lobulated and is not covered by normal unaffected parotid tissue. In other words, when you dissect in the plane of the facial nerve, more often than not, the nerve is in direct contact with the tumor.
This is the histology of that specimen showing one of the oscillations or nodules arising from the pleomorphic adenoma. And you can see that the capsule is deficient around the actual nodule. Now this means that although we talk about formal parotidectomy with the dissection of the facial nerve as being the gold standard for the management of parotid tumors, we kid ourselves if we think we're removing the tumor with a cuff of unaffected tissue, we're not.
