Is Mohs surgery safe with cheek implants?

Thank you for the excellent question.  Cheek implants are normally placed in the deeper subcutaneous tissues so these are not normally an issue for Mohs surgery for superficial skin cancers on the cheek. You should definitely discuss your previous surgery with your Mohs surgeon so that they can take into account scarring and tissue rearrangement from your previous implants.
I hope your Mohs surgery went well and that you are cancer free with an excellent cosmetic result.

The plane of dissection would typically be different. Cheek implants are placed directly on bone while Mohs is a more superficial type of surgery and takes place on the skin surface and rarely goes deeper than the fat under the skin.You should be safe having Mohs on the cheek but I would first consult with your cheek implant surgeon or another facial plastic surgeon.

Hi greetings from the UK. Presumably you're contemplating Moh's surgery for some sort of cheek located malignancy. Cheek implants are typically located beneath the muscle whereas most Mohs surgery is limited to a more superficial plane above the facial musculature- hence it's pretty rare that one should expose the implants so the risk of an infection of the implant is pretty uncommon. Best Wishes and good luckDavid
