How necessary is a lacrimal gland biopsy with prolapse? (Photo)

If there are suspicious signs or the gland looks abnormal, then biopsy is warranted. Otherwise biopsy is not necessary for purely prolapsed lacrimal glands especially when both sides are prolapsed as in your case.

The biopsy supports that argument that it is being done for medical reasons rather than cosmetic reasons. I would not fault a surgeon for biopsy. However, there is no reason to think this herniated lacrimal gland is abnormal. I would biopsy this gland but the procedure is cosmetic but insurance would likely cover the pathology fees. For peace of mind, you may want the biopsy. There is very little downside.

typically the biopsy and repositioning can be done all in the same surgery. Yes, I would always recommend a biopsy in this situation. Even a normal appearing lacrimal gland can sometimes have issues that would only be revealed by biopsying in the tissue. Best of luck!

The picture shows upper eyelid ptosis and herniation of the lacrimal gland. You use your forehead muscle to see better and that causes over stretched upper lids. There is no need for biopsy. You should have do both(ptosis and herniated gland) at the same time. Please see the link
