Prosthesis or reconstruction: two answers, not rivals

Few questions in this field are asked as often as this one: should the missing part be rebuilt by surgery, or replaced with a prosthesis? This site's view is that the question is better put as which answer, or which combination, suits this person and this site. Neither is a failure of the other. The clinical sources opened for this page do not rank the two in general; they describe factors, and they say the decision is shared. What follows is background for that conversation, not advice about it.

What each approach does

Reconstruction uses the person's own tissue, moved from elsewhere in the body, to rebuild the lost part. The UK national multidisciplinary guidelines on reconstruction after head and neck cancer surgery describe flaps and grafts of this kind, with the choice of flap depending on the plan for rehabilitation. A prosthesis replaces the part with a made one, as explained on what a facial prosthesis is. A review in the International Journal of Dentistry says plastic surgery is generally preferred over artificial replacement when it is appropriate, while noting that several defects still need prosthetic restoration.

The two traditions grew together. A 2021 history of nasal reconstruction in Current Opinion in Otolaryngology and Head and Neck Surgery traces reconstruction by flaps to the Indian surgeon Sushruta, dated by that article to about 600 BC, and to Gaspare Tagliacozzi of Bologna, whose treatise of 1597 described a method using skin from the arm. On the prosthetic side, the same centuries produced the artificial noses and ears described by Ambroise Pare. Both lines appear on the timeline.

What teams commonly weigh

The Heidelberg review of implant-retained prostheses lists indications for choosing a bone-anchored prosthesis, which doubles as a list of factors teams discuss: the need for optimal tumor aftercare, for example when the risk of recurrence is high; local or general reasons that make reconstructive surgery unsuitable, such as skin severely damaged by radiation or poor general condition; use during stages of a plastic reconstruction as an interim prosthesis; failed earlier reconstruction; the patient's own choice not to have reconstructive surgery; high aesthetic demands; and the wish for speedy rehabilitation. The UK guidelines say the choice of prosthetic option or reconstruction depends on the nature of the defect.

Those guidelines add two further points. There are clear advantages in simplifying the surgery and using prosthetic options, they say, but the choice becomes harder to deliver, and harder for the patient to cope with, as the defect becomes larger and more complex. And reconstructive procedures carry their own risks, including flap failure, donor-site problems and, in the larger operations the guidelines discuss, swallowing and voice difficulties and a small perioperative mortality rate. A 2016 paper on photogrammetry makes a less technical point: some aesthetic results can be reached by plastic surgery, but this frequently requires multiple attempts that are time consuming and costly.

It depends on the site

The Heidelberg review is specific that the answer differs by structure. Plastic surgery, it says, is extremely suitable for less complex aesthetic units or partial defects of the ear, nose and eye socket, while particularly mobile areas such as the lips are difficult to treat with prostheses and should definitely be surgically reconstructed, even if a remaining defect is treated with a prosthesis. The UK guidelines discuss obturating small palate defects, gaining very good retention for extensive upper jaw defects with an implant-retained prosthesis, leaving room for an orbital prosthesis when the eye socket is involved, and rehabilitating a classical removal of the nose with a prosthesis. For the nose, the guidelines add that the surgeon can check the margins of the resection and remove more tissue if needed, which is part of why prosthetic planning and cancer surgery are discussed together.

Using both

The two are frequently combined. The implant review describes prostheses used as interim devices during stages of reconstructive surgery, and surgical preparation of the site, such as thinning the skin around an implant, as part of bone-anchored prosthetic care. The page on bone-anchored implants explains that process. The UK guidelines recommend that all cases involving loss of the upper jaw or midface be discussed in a multidisciplinary setting.

A shared decision

The same guidelines state who should be in the conversation: the choice of reconstruction or prosthetics requires discussion among the ablative and reconstructive teams, the prosthodontist, the maxillofacial technician, the patient and the family. A Turkish study frames prostheses as an alternative to surgery that offers non-operative rehabilitation, aiming at acceptable appearance and a return to family and social life. What life with one is like is explored on living with a facial prosthesis.

Nothing here recommends one route. If you are facing this choice, useful things to ask your clinical team include what each route involves, what follow-up it needs, how it fits with any cancer treatment, and what the remaking or revision schedule looks like. Your team has the final word, and a second opinion is a normal part of care.

In brief

Reconstruction rebuilds with the body's own tissue and a prosthesis replaces with a made part. Teams weigh the site and size of the defect, radiation history, cancer follow-up, the person's own preferences and more, and often use both. Neither is a failure of the other, and the choice is one to make with a multidisciplinary team.
