What a facial prosthesis is, and what it is not
A facial prosthesis is a made part that replaces tissue the body no longer has. Here is who makes one, how it stays on, and where surgery fits beside it.
Most people meet the idea of a facial prosthesis at a hard moment: a cancer operation that removes an ear, an injury that takes part of the nose, an eye that has to go. The question that follows is simple and rarely answered well. What exactly is this thing, and how does it differ from an operation? This page sets out the basic picture, using clinical reviews and hospital patient information, so that the other pages on this site have a place to start from.
A made part that replaces missing tissue
A review of the field in the International Journal of Dentistry describes maxillofacial deformities as conditions that can be congenital, caused by malformation or developmental disturbance, or acquired through disease treatment or trauma. The same review notes that plastic surgery is generally preferred over artificial replacement when it is appropriate, and that several congenital and acquired defects still call for a prosthetic restoration. A facial prosthesis is the made replacement: an ear, a nose, an eye socket with its surrounding tissue, a cheek, or another part of the face, built to fill the gap.
The same review lists eyes, ears, nose, upper jaw, lower jaw and palate among the structures that can be replaced, and says the prostheses are primarily made of acrylic resin, silicone, or both, shaped to the person's own facial structure. Other pages here cover the materials and the making in detail.
Jaw, palate and the inside of the mouth
The word "facial" can hide half the field. The review sorts maxillofacial prostheses into oral, ocular and facial types, among others. When part of the roof of the mouth has been removed, a palatal obturator closes the opening between the mouth and the nasal cavity. According to the review, it is made to restore speech and to improve chewing and swallowing. It can be made before an operation and fitted straight afterward to protect the surgical cavity, or made a few weeks later once there has been time for healing.
Jaw and tongue prostheses exist too. The review says mandibular and tongue prostheses can be used when reconstructive surgery inside the mouth is not an option. These are less visible to the world but central to eating and speaking, and they belong to the same family of work.
How a prosthesis stays in place
A prosthesis that falls off is of little use, so retention is a central question. A review of implant-retained craniofacial prostheses names four ways to hold one in place: anatomical anchorage, such as undercut areas inside an eye socket; mechanical anchorage, for example to a spectacle frame; chemical anchorage with adhesives; and surgical anchorage, which today means titanium implants that pass through the skin and are anchored in bone. Cambridge University Hospitals describes the two common patient experiences in its leaflets: an adhesive-retained prosthesis is applied to clean, dry skin with medical adhesive, while an implant-retained one is held by magnets on the implants. The bone route has its own page, bone-anchored implants.
Who makes them
Several professions overlap here, and their names and legal standing differ from country to country. The American Academy of Maxillofacial Prosthetics describes maxillofacial prosthetics as a subspecialty of prosthodontics concerned with rehabilitating patients who have defects or disabilities. A 2022 review in Frontiers in Oral Health says maxillofacial prosthodontists earn their title through a further specialization in prosthodontics, and that anaplastology began as a formal training program at Stanford University in 1971 through Walter Spohn. The International Anaplastology Association was founded in 1980 under the name American Anaplastology Association, according to the same review.
The review also makes a point worth keeping in mind: where national law does not recognize anaplastology or ocularistry, practitioners have no legal footing to provide care in that country. So the person who makes a prosthesis for you could be a dental specialist, an anaplastologist, an ocularist, or a technician working inside a hospital laboratory, depending on where you live. In every account the work is a team effort, which the Frontiers review says includes cancer surveillance, biomaterials, osseointegration and what it calls hyper-realistic artistic skills.
Beside surgery, not instead of it
One study of facial prostheses calls them an alternative to surgery that provides non-operative rehabilitation, aiming at acceptable appearance and a return to family and social life. That is a fair summary of what a prosthesis offers, as long as "alternative" is not read as "rival". Surgeons and prosthetic teams often work on the same person: surgery to prepare the site, a prosthesis for the part that is missing. The page on prosthesis or reconstruction looks at how teams think it through.
Some parts of the face suit one answer better than another. The implant review observes that very mobile areas such as the lips are hard to treat with a prosthesis and should be surgically reconstructed, even where a remaining defect is covered with a prosthesis. That sentence is a reminder that decisions are made site by site, not by principle.
What a prosthesis cannot do
A prosthesis does not grow, heal or feel. The Cambridge leaflets say the silicone colors fade with ultraviolet light and skin oils, that a prosthesis should last 12 to 18 months with careful maintenance, and that patients have six-monthly reviews with the maxillofacial prosthetist. The long history of the craft, set out on the timeline, includes many materials that wore out faster. Edges are thin and can tear, and the leaflets advise against wearing a prosthesis in bed or for contact sports. None of this is a failure of the idea. It is the ordinary maintenance of a made object worn on a living face.
Your own clinical team has the final word on everything above. If a prosthesis no longer fits, the skin underneath is sore or red, or anything about the face changes, that is a reason to contact the team that looks after you rather than adjust or repair it yourself.
Questions people ask
Is a facial prosthesis permanent?
No. Cambridge University Hospitals says its silicone prostheses should last 12 to 18 months with careful maintenance, because the colors fade. A 2024 review of silicones gives an average lifespan of about 2 years, and an earlier review mentions silicones lasting as little as 6 months. Replacement is a normal part of care.
Who decides between a prosthesis and surgery?
It is a decision for the person and their clinical team. The UK national guidelines for head and neck cancer reconstruction say the choice of reconstruction or prosthetics should involve the surgical teams, the prosthodontist, the maxillofacial technician, the patient and the family.
Is a facial prosthesis the same as a dental prosthesis?
They overlap. Obturators and jaw prostheses sit inside the mouth and are made by dental specialists, while facial prostheses such as ears and noses sit on the skin. The maxillofacial field covers both, which is why its specialists often come from prosthodontics.
In brief
A facial prosthesis is a made replacement for tissue that is missing, held on by anatomy, glasses, adhesive or bone-anchored attachments. It sits beside surgery as another tool, and it asks for ongoing care and periodic remaking. The people who make one differ by country, and the clinical team treating you decides what is suitable.
