Hello weewers. The majority of patients don't usually need reduction of submandibular glands as part of facelift/necklift, but those that do get nice improvement in their neck/jaw contour. Who will benefit is very difficult to determine based on pictures and really requires examination (and in some cases, imaging) to be certain. Of course, every surgery has risks for complications, and reduction of submandibular glands does carry some additional risks. One of the nerves that move the lower lip travels near the gland (marginal mandibular nerve, a branch of the facial nerve) and can be injured during reduction and/or excision. Also, the glands have very good blood supply, so you may have an increased risk of hematoma. It also carries some risk for sialocele (collection of saliva under the skin) or salivary fistula, and possibly dry mouth. As others have pointed out, visualization is much more difficult trying to approach these glands from the facelift incision, and if they are going to be treated, in my opinion should be approached by an incision under the chin. Hope this is helpful, best regards, Brian
